# E2E BDD Test Coverage Assistant
You are an E2E testing assistant. Your task is to add BDD behavior tests to improve E2E coverage for the LobeHub application.
## Prerequisites
Before starting, read the following documents:
- `e2e/CLAUDE.md` - E2E testing guide and best practices
- `e2e/docs/local-setup.md` - Local environment setup
## Target Modules
Based on the product architecture, prioritize modules by coverage status:
| Module | Sub-features | Priority | Status |
| ---------------- | --------------------------------------------------- | -------- | ------ |
| **Agent** | Builder, Conversation, Task | P0 | 🚧 |
| **Agent Group** | Builder, Group Chat | P0 | ⏳ |
| **Page (Docs)** | Sidebar CRUD ✅, Title/Emoji ✅, Rich Text ✅, Copilot | P0 | 🚧 |
| **Knowledge** | Create, Upload, RAG Conversation | P1 | ⏳ |
| **Memory** | View, Edit, Associate | P2 | ⏳ |
| **Home Sidebar** | Agent Mgmt, Group Mgmt | P1 | ✅ |
| **Community** | Browse, Interactions, Detail Pages | P1 | ✅ |
| **Settings** | User Settings, Model Provider | P2 | ⏳ |
## Workflow
### 1. Analyze Current Coverage
**Step 1.1**: List existing feature files
```bash
find e2e/src/features -name "*.feature" -type f
```
**Step 1.2**: Review the product modules in `src/app/[variants]/(main)/` to identify untested user journeys
**Step 1.3**: Check `e2e/CLAUDE.md` for the coverage matrix and identify gaps
### 2. Select a Module to Test
**Selection Criteria**:
- Choose ONE module that is NOT yet covered or has incomplete coverage
- Prioritize by: P0 > P1 > P2
- Focus on user journeys that represent core product value
**Module granularity examples**:
- Agent conversation flow
- Knowledge base RAG workflow
- Settings configuration flow
- Page document CRUD operations
### 3. Create Module Directory and README
**Step 3.1**: Create dedicated feature directory
```bash
mkdir -p e2e/src/features/{module-name}
```
**Step 3.2**: Create README.md with feature inventory
Create `e2e/src/features/{module-name}/README.md` with:
- Module overview and routes
- Feature inventory table (功能点、描述、优先级、状态、测试文件)
- Test file structure
- Execution commands
- Known issues
**Example structure** (see `e2e/src/features/page/README.md`):
```markdown
# {Module} 模块 E2E 测试覆盖
## 模块概述
**路由**: `/module`, `/module/[id]`
## 功能清单与测试覆盖
### 1. 功能分组名称
| 功能点 | 描述 | 优先级 | 状态 | 测试文件 |
| ------ | ---- | ------ | ---- | -------- |
| 功能A | xxx | P0 | ✅ | `xxx.feature` |
| 功能B | xxx | P1 | ⏳ | |
## 测试文件结构
## 测试执行
## 已知问题
## 更新记录
```
### 4. Explore Module Features
**Step 4.1**: Use Task tool to explore the module
```
Use the Task tool with subagent_type=Explore to thoroughly explore:
- Route structure in src/app/[variants]/(main)/{module}/
- Feature components in src/features/
- Store actions in src/store/{module}/
- All user interactions (buttons, menus, forms)
```
**Step 4.2**: Document all features in README.md
Group features by user journey area (e.g., Sidebar, Editor Header, Editor Content, etc.)
### 5. Design Test Scenarios
**Step 5.1**: Create feature files by functional area
Feature file location: `e2e/src/features/{module}/{area}.feature`
**Naming conventions**:
- `crud.feature` - Basic CRUD operations
- `editor-meta.feature` - Editor metadata (title, icon)
- `editor-content.feature` - Rich text editing
- `copilot.feature` - AI copilot interactions
**Feature file template**:
```gherkin
@journey @P0 @{module-tag}
Feature: {Feature Name in Chinese}
{user goal}
便 {business value}
Background:
Given
# ============================================
# 功能分组注释
# ============================================
@{MODULE-AREA-001}
Scenario: {Scenario description in Chinese}
Given {precondition}
When {user action}
Then {expected outcome}
And {additional verification}
```
**Tag conventions**:
```gherkin
@journey # User journey test (experience baseline)
@smoke # Smoke test (quick validation)
@regression # Regression test
@skip # Skip this test (known issue)
@P0 # Highest priority (CI must run)
@P1 # High priority (Nightly)
@P2 # Medium priority (Pre-release)
@agent # Agent module
@agent-group # Agent Group module
@page # Page/Docs module
@knowledge # Knowledge base module
@memory # Memory module
@settings # Settings module
@home # Home sidebar module
```
### 6. Implement Step Definitions
**Step 6.1**: Create step definition file
Location: `e2e/src/steps/{module}/{area}.steps.ts`
**Step definition template**:
```typescript
/**
* {Module} {Area} Steps
*
* Step definitions for {description}
*/
import { Given, When, Then } from '@cucumber/cucumber';
import { expect } from '@playwright/test';
import { CustomWorld } from '../../support/world';
// ============================================
// Given Steps
// ============================================
Given('用户打开一个文稿编辑器', async function (this: CustomWorld) {
console.log(' 📍 Step: 创建并打开一个文稿...');
// Implementation
console.log(' ✅ 已打开文稿编辑器');
});
// ============================================
// When Steps
// ============================================
When('用户点击标题输入框', async function (this: CustomWorld) {
console.log(' 📍 Step: 点击标题输入框...');
// Implementation
console.log(' ✅ 已点击标题输入框');
});
// ============================================
// Then Steps
// ============================================
Then('文稿标题应该更新为 {string}', async function (this: CustomWorld, title: string) {
console.log(` 📍 Step: 验证标题为 "${title}"...`);
// Assertions
console.log(` ✅ 标题已更新为 "${title}"`);
});
```
**Step 6.2**: Add hooks if needed
Update `e2e/src/steps/hooks.ts` for new tag prefixes:
```typescript
const testId = pickle.tags.find(
(tag) =>
tag.name.startsWith('@COMMUNITY-') ||
tag.name.startsWith('@AGENT-') ||
tag.name.startsWith('@HOME-') ||
tag.name.startsWith('@PAGE-') || // Add new prefix
tag.name.startsWith('@ROUTES-'),
);
```
### 7. Setup Mocks (If Needed)
For LLM-related tests, use the mock framework:
```typescript
import { llmMockManager, presetResponses } from '../../mocks/llm';
// Setup mock before navigation
llmMockManager.setResponse('user message', 'Expected AI response');
await llmMockManager.setup(this.page);
```
### 8. Run and Verify Tests
**Step 8.1**: Start local environment
```bash
# From project root
bun e2e/scripts/setup.ts --start
```
**Step 8.2**: Run dry-run first to verify step definitions
```bash
cd e2e
BASE_URL=http://localhost:3006 \
DATABASE_URL=postgresql://postgres:postgres@localhost:5433/postgres \
pnpm exec cucumber-js --config cucumber.config.js --tags "@{module-tag}" --dry-run
```
**Step 8.3**: Run the new tests
```bash
# Run specific test by tag
HEADLESS=false BASE_URL=http://localhost:3006 \
DATABASE_URL=postgresql://postgres:postgres@localhost:5433/postgres \
pnpm exec cucumber-js --config cucumber.config.js --tags "@{TEST-ID}"
# Run all module tests (excluding skipped)
HEADLESS=true BASE_URL=http://localhost:3006 \
DATABASE_URL=postgresql://postgres:postgres@localhost:5433/postgres \
pnpm exec cucumber-js --config cucumber.config.js --tags "@{module-tag} and not @skip"
```
**Step 8.4**: Fix any failures
- Check screenshots in `e2e/screenshots/`
- Adjust selectors and waits as needed
- For flaky tests, add `@skip` tag and document in README known issues
- Ensure tests pass consistently
### 9. Update Documentation
**Step 9.1**: Update module README.md
- Mark completed features with ✅
- Update test statistics
- Add any known issues
**Step 9.2**: Update this prompt file
- Update module status in Target Modules table
- Add any new best practices learned
### 10. Create Pull Request
- Branch name: `test/e2e-{module-name}`
- Commit message format:
```
✅ test: add E2E tests for {module-name}
```
- PR title: `✅ test: add E2E tests for {module-name}`

## Important Rules
- **DO** write feature files in Chinese (贴近产品需求)
- **DO** add appropriate tags (@journey, @P0/@P1/@P2, @module-name)
- **DO** mock LLM responses for stability
- **DO** add console logs in step definitions for debugging
- **DO** handle element visibility issues (desktop/mobile dual components)
- **DO** use `page.waitForTimeout()` for animation/transition waits
- **DO** support both Chinese and English text (e.g., `/^(无标题|Untitled)$/`)
- **DO** create unique test data with timestamps to avoid conflicts
- **DO NOT** depend on actual LLM API calls
- **DO NOT** create flaky tests (ensure stability before PR)
- **DO NOT** modify production code unless adding data-testid attributes
- **DO NOT** skip running tests locally before creating PR
## Element Locator Best Practices
### Rich Text Editor (contenteditable)
```typescript
// Correct way to input in contenteditable
const editor = this.page.locator('[contenteditable="true"]').first();
await editor.click();
await this.page.waitForTimeout(500);
await this.page.keyboard.type(message, { delay: 30 });
```
### Slash Commands
```typescript
// Type slash and wait for menu to appear
await this.page.keyboard.type('/', { delay: 100 });
await this.page.waitForTimeout(800); // Wait for slash menu
// Type command shortcut
await this.page.keyboard.type('h1', { delay: 80 });
await this.page.keyboard.press('Enter');
```
### Handling i18n (Chinese/English)
```typescript
// Support both languages for default values
const defaultTitleRegex = /^(无标题|Untitled)$/;
const pageItem = this.page.getByText(defaultTitleRegex).first();
// Or for buttons
const button = this.page.getByRole('button', { name: /choose.*icon|选择图标/i });
```
### Creating Unique Test Data
```typescript
// Use timestamps to avoid conflicts between test runs
const uniqueTitle = `E2E Page ${Date.now()}`;
```
### Handling Multiple Matches
```typescript
// Use .first() or .nth() for multiple matches
const element = this.page.locator('[data-testid="item"]').first();
// Or filter by visibility
const items = await this.page.locator('[data-testid="item"]').all();
for (const item of items) {
if (await item.isVisible()) {
await item.click();
break;
}
}
```
### Adding data-testid
If needed for reliable element selection, add `data-testid` to components:
```tsx
<Component data-testid="unique-identifier" />
```
## Common Test Patterns
### Navigation Test
```gherkin
Scenario: 用户导航到目标页面
Given 用户已登录系统
When 用户点击侧边栏的 "{menu-item}"
Then 应该跳转到 "{expected-url}"
And 页面标题应包含 "{expected-title}"
```
### CRUD Test
```gherkin
Scenario: 创建新项目
Given 用户已登录系统
When 用户点击创建按钮
And 用户输入名称 "{name}"
And 用户点击保存
Then 应该看到新创建的项目 "{name}"
Scenario: 编辑项目
Given 用户已创建项目 "{name}"
When 用户打开项目编辑
And 用户修改名称为 "{new-name}"
And 用户保存更改
Then 项目名称应更新为 "{new-name}"
Scenario: 删除项目
Given 用户已创建项目 "{name}"
When 用户删除该项目
And 用户确认删除
Then 项目列表中不应包含 "{name}"
```
### Editor Title/Meta Test
```gherkin
Scenario: 编辑文稿标题
Given 用户打开一个文稿编辑器
When 用户点击标题输入框
And 用户输入标题 "我的测试文稿"
And 用户按下 Enter 键
Then 文稿标题应该更新为 "我的测试文稿"
```
### Rich Text Editor Test
```gherkin
Scenario: 通过斜杠命令插入一级标题
Given 用户打开一个文稿编辑器
When 用户点击编辑器内容区域
And 用户输入斜杠命令 "/h1"
And 用户按下 Enter 键
And 用户输入文本 "一级标题内容"
Then 编辑器应该包含一级标题
```
### LLM Interaction Test
```gherkin
Scenario: AI 对话基本流程
Given 用户已登录系统
And LLM Mock 已配置
When 用户发送消息 "{user-message}"
Then 应该收到 AI 回复 "{expected-response}"
And 消息应显示在对话历史中
```
## Debugging Tips
1. **Use HEADLESS=false** to see browser actions
2. **Check screenshots** in `e2e/screenshots/` on failure
3. **Add console.log** in step definitions
4. **Increase timeouts** for slow operations
5. **Use `page.pause()`** for interactive debugging
6. **Run dry-run first** to verify all step definitions exist
7. **Use @skip tag** for known flaky tests, document in README
## Reference Implementations

# Vercel React Best Practices
Comprehensive performance optimization guide for React and Next.js applications, maintained by Vercel. Contains 45 rules across 8 categories, prioritized by impact to guide automated refactoring and code generation.
## When to Apply
Reference these guidelines when:
- Writing new React components or Next.js pages
- Implementing data fetching (client or server-side)
- Reviewing code for performance issues
- Refactoring existing React/Next.js code
- Optimizing bundle size or load times
## Rule Categories by Priority
| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | Eliminating Waterfalls | CRITICAL | `async-` |
| 2 | Bundle Size Optimization | CRITICAL | `bundle-` |
| 3 | Server-Side Performance | HIGH | `server-` |
| 4 | Client-Side Data Fetching | MEDIUM-HIGH | `client-` |
| 5 | Re-render Optimization | MEDIUM | `rerender-` |
| 6 | Rendering Performance | MEDIUM | `rendering-` |
| 7 | JavaScript Performance | LOW-MEDIUM | `js-` |
| 8 | Advanced Patterns | LOW | `advanced-` |
## Quick Reference
### 1. Eliminating Waterfalls (CRITICAL)
- `async-defer-await` - Move await into branches where actually used
- `async-parallel` - Use Promise.all() for independent operations
- `async-dependencies` - Use better-all for partial dependencies
- `async-api-routes` - Start promises early, await late in API routes
- `async-suspense-boundaries` - Use Suspense to stream content
### 2. Bundle Size Optimization (CRITICAL)
- `bundle-barrel-imports` - Import directly, avoid barrel files
- `bundle-dynamic-imports` - Use next/dynamic for heavy components
- `bundle-defer-third-party` - Load analytics/logging after hydration
- `bundle-conditional` - Load modules only when feature is activated
- `bundle-preload` - Preload on hover/focus for perceived speed
### 3. Server-Side Performance (HIGH)
- `server-cache-react` - Use React.cache() for per-request deduplication
- `server-cache-lru` - Use LRU cache for cross-request caching
- `server-serialization` - Minimize data passed to client components
- `server-parallel-fetching` - Restructure components to parallelize fetches
- `server-after-nonblocking` - Use after() for non-blocking operations
### 4. Client-Side Data Fetching (MEDIUM-HIGH)
- `client-swr-dedup` - Use SWR for automatic request deduplication
- `client-event-listeners` - Deduplicate global event listeners
### 5. Re-render Optimization (MEDIUM)
- `rerender-defer-reads` - Don't subscribe to state only used in callbacks
- `rerender-memo` - Extract expensive work into memoized components
- `rerender-dependencies` - Use primitive dependencies in effects
- `rerender-derived-state` - Subscribe to derived booleans, not raw values
- `rerender-functional-setstate` - Use functional setState for stable callbacks
- `rerender-lazy-state-init` - Pass function to useState for expensive values
- `rerender-transitions` - Use startTransition for non-urgent updates
### 6. Rendering Performance (MEDIUM)
- `rendering-animate-svg-wrapper` - Animate div wrapper, not SVG element
- `rendering-content-visibility` - Use content-visibility for long lists
- `rendering-hoist-jsx` - Extract static JSX outside components
- `rendering-svg-precision` - Reduce SVG coordinate precision
- `rendering-hydration-no-flicker` - Use inline script for client-only data
- `rendering-activity` - Use Activity component for show/hide
- `rendering-conditional-render` - Use ternary, not && for conditionals
### 7. JavaScript Performance (LOW-MEDIUM)
- `js-batch-dom-css` - Group CSS changes via classes or cssText
- `js-index-maps` - Build Map for repeated lookups
- `js-cache-property-access` - Cache object properties in loops
- `js-cache-function-results` - Cache function results in module-level Map
- `js-cache-storage` - Cache localStorage/sessionStorage reads
- `js-combine-iterations` - Combine multiple filter/map into one loop
- `js-length-check-first` - Check array length before expensive comparison
- `js-early-exit` - Return early from functions
- `js-hoist-regexp` - Hoist RegExp creation outside loops
- `js-min-max-loop` - Use loop for min/max instead of sort
- `js-set-map-lookups` - Use Set/Map for O(1) lookups
- `js-tosorted-immutable` - Use toSorted() for immutability
### 8. Advanced Patterns (LOW)
- `advanced-event-handler-refs` - Store event handlers in refs
- `advanced-use-latest` - useLatest for stable callback refs
## How to Use
Read individual rule files for detailed explanations and code examples:
```
rules/async-parallel.md
rules/bundle-barrel-imports.md
rules/_sections.md
```
Each rule file contains:
- Brief explanation of why it matters
- Incorrect code example with explanation
- Correct code example with explanation
- Additional context and references

## Store Event Handlers in Refs
Store callbacks in refs when used in effects that shouldn't re-subscribe on callback changes.
**Incorrect (re-subscribes on every render):**
```tsx
function useWindowEvent(event: string, handler: (e) => void) {
useEffect(() => {
window.addEventListener(event, handler)
return () => window.removeEventListener(event, handler)
}, [event, handler])
}
```
**Correct (stable subscription):**
```tsx
function useWindowEvent(event: string, handler: (e) => void) {
const handlerRef = useRef(handler)
useEffect(() => {
handlerRef.current = handler
}, [handler])
useEffect(() => {
const listener = (e) => handlerRef.current(e)
window.addEventListener(event, listener)
return () => window.removeEventListener(event, listener)
}, [event])
}
```
**Alternative: use `useEffectEvent` if you're on latest React:**
```tsx
import { useEffectEvent } from 'react'
function useWindowEvent(event: string, handler: (e) => void) {
const onEvent = useEffectEvent(handler)
useEffect(() => {
window.addEventListener(event, onEvent)
return () => window.removeEventListener(event, onEvent)
}, [event])
}
```
`useEffectEvent` provides a cleaner API for the same pattern: it creates a stable function reference that always calls the latest version of the handler.

return () => clearTimeout(timeout)
}, [query, onSearch])
}

const [query, setQuery] = useState('')
const onSearchRef = useLatest(onSearch)

## Prevent Waterfall Chains in API Routes
In API routes and Server Actions, start independent operations immediately, even if you don't await them yet.
**Incorrect (config waits for auth, data waits for both):**
```typescript
export async function GET(request: Request) {
const session = await auth()
const config = await fetchConfig()
const data = await fetchData(session.user.id)
return Response.json({ data, config })
}
```
**Correct (auth and config start immediately):**
```typescript
export async function GET(request: Request) {
const sessionPromise = auth()
const configPromise = fetchConfig()
const session = await sessionPromise
const [config, data] = await Promise.all([
configPromise,
fetchData(session.user.id)
])
return Response.json({ data, config })
}
```
For operations with more complex dependency chains, use `better-all` to automatically maximize parallelism (see Dependency-Based Parallelization).

title: Defer Await Until Needed
impact: HIGH
impactDescription: avoids blocking unused code paths
tags: async, await, conditional, optimization
---
## Defer Await Until Needed
Move `await` operations into the branches where they're actually used to avoid blocking code paths that don't need them.
**Incorrect (blocks both branches):**
```typescript
async function handleRequest(userId: string, skipProcessing: boolean) {
const userData = await fetchUserData(userId)
if (skipProcessing) {
// Returns immediately but still waited for userData
return { skipped: true }
}
// Only this branch uses userData
return processUserData(userData)
}
```
**Correct (only blocks when needed):**
```typescript
async function handleRequest(userId: string, skipProcessing: boolean) {
if (skipProcessing) {
// Returns immediately without waiting
return { skipped: true }
}
// Fetch only when needed
const userData = await fetchUserData(userId)
return processUserData(userData)
}
```
**Another example (early return optimization):**
```typescript
// Incorrect: always fetches permissions
async function updateResource(resourceId: string, userId: string) {
const permissions = await fetchPermissions(userId)
const resource = await getResource(resourceId)
if (!resource) {
return { error: 'Not found' }
}
if (!permissions.canEdit) {
return { error: 'Forbidden' }
}
return await updateResourceData(resource, permissions)
}
// Correct: fetches only when needed
async function updateResource(resourceId: string, userId: string) {
const resource = await getResource(resourceId)
if (!resource) {
return { error: 'Not found' }
}
const permissions = await fetchPermissions(userId)
if (!permissions.canEdit) {
return { error: 'Forbidden' }
}
return await updateResourceData(resource, permissions)
}
```
This optimization is especially valuable when the skipped branch is frequently taken, or when the deferred operation is expensive.

fetchUser(),

async config() { return fetchConfig() },
async profile() {

title: Strategic Suspense Boundaries
impact: HIGH
impactDescription: faster initial paint
tags: async, suspense, streaming, layout-shift
---
## Strategic Suspense Boundaries
Instead of awaiting data in async components before returning JSX, use Suspense boundaries to show the wrapper UI faster while data loads.
**Incorrect (wrapper blocked by data fetching):**
```tsx
async function Page() {
const data = await fetchData() // Blocks entire page
return (
<div>
<div>Sidebar</div>
<div>Header</div>
<div>
<DataDisplay data={data} />
</div>
<div>Footer</div>
</div>
)
}
```
The entire layout waits for data even though only the middle section needs it.
**Correct (wrapper shows immediately, data streams in):**
```tsx
function Page() {
return (
<div>
<div>Sidebar</div>
<div>Header</div>
<div>
<Suspense fallback={<Skeleton />}>
<DataDisplay />
</Suspense>
</div>
<div>Footer</div>
</div>
)
}
async function DataDisplay() {
const data = await fetchData() // Only blocks this component
return <div>{data.content}</div>
}
```
Sidebar, Header, and Footer render immediately. Only DataDisplay waits for data.
**Alternative (share promise across components):**
```tsx
function Page() {
// Start fetch immediately, but don't await
const dataPromise = fetchData()
return (
<div>
<div>Sidebar</div>
<div>Header</div>
<Suspense fallback={<Skeleton />}>
<DataDisplay dataPromise={dataPromise} />
<DataSummary dataPromise={dataPromise} />
</Suspense>
<div>Footer</div>
</div>
)
}
function DataDisplay({ dataPromise }: { dataPromise: Promise<Data> }) {
const data = use(dataPromise) // Unwraps the promise
return <div>{data.content}</div>
}
function DataSummary({ dataPromise }: { dataPromise: Promise<Data> }) {
const data = use(dataPromise) // Reuses the same promise
return <div>{data.summary}</div>
}
```
Both components share the same promise, so only one fetch occurs. Layout renders immediately while both components wait together.
**When NOT to use this pattern:**
- Critical data needed for layout decisions (affects positioning)
- SEO-critical content above the fold
- Small, fast queries where suspense overhead isn't worth it
- When you want to avoid layout shift (loading → content jump)
**Trade-off:** Faster initial paint vs potential layout shift. Choose based on your UX priorities.

title: Avoid Barrel File Imports
impact: CRITICAL
impactDescription: 200-800ms import cost, slow builds
tags: bundle, imports, tree-shaking, barrel-files, performance
---
## Avoid Barrel File Imports
Import directly from source files instead of barrel files to avoid loading thousands of unused modules. **Barrel files** are entry points that re-export multiple modules (e.g., `index.js` that does `export * from './module'`).
Popular icon and component libraries can have **up to 10,000 re-exports** in their entry file. For many React packages, **it takes 200-800ms just to import them**, affecting both development speed and production cold starts.
**Why tree-shaking doesn't help:** When a library is marked as external (not bundled), the bundler can't optimize it. If you bundle it to enable tree-shaking, builds become substantially slower analyzing the entire module graph.
**Incorrect (imports entire library):**
```tsx
import { Check, X, Menu } from 'lucide-react'
// Loads 1,583 modules, takes ~2.8s extra in dev
// Runtime cost: 200-800ms on every cold start
import { Button, TextField } from '@mui/material'
// Loads 2,225 modules, takes ~4.2s extra in dev
```
**Correct (imports only what you need):**
```tsx
import Check from 'lucide-react/dist/esm/icons/check'
import X from 'lucide-react/dist/esm/icons/x'
import Menu from 'lucide-react/dist/esm/icons/menu'
// Loads only 3 modules (~2KB vs ~1MB)
import Button from '@mui/material/Button'
import TextField from '@mui/material/TextField'
// Loads only what you use
```
**Alternative (Next.js 13.5+):**
```js
// next.config.js - use optimizePackageImports
module.exports = {
experimental: {
optimizePackageImports: ['lucide-react', '@mui/material']
}
}
// Then you can keep the ergonomic barrel imports:
import { Check, X, Menu } from 'lucide-react'
// Automatically transformed to direct imports at build time
```
Direct imports provide 15-70% faster dev boot, 28% faster builds, 40% faster cold starts, and significantly faster HMR.
Libraries commonly affected: `lucide-react`, `@mui/material`, `@mui/icons-material`, `@tabler/icons-react`, `react-icons`, `@headlessui/react`, `@radix-ui/react-*`, `lodash`, `ramda`, `date-fns`, `rxjs`, `react-use`.

**Always wrap in try-catch:** `getItem()` and `setItem()` throw in incognito/private browsing (Safari, Firefox), when quota exceeded, or when disabled.
**Benefits:** Schema evolution via versioning, reduced storage size, prevents storing tokens/PII/internal flags.

---
## Use Passive Event Listeners for Scrolling Performance
Add `{ passive: true }` to touch and wheel event listeners to enable immediate scrolling. Browsers normally wait for listeners to finish to check if `preventDefault()` is called, causing scroll delay.
**Incorrect:**
```typescript
useEffect(() => {
const handleTouch = (e: TouchEvent) => console.log(e.touches[0].clientX)
const handleWheel = (e: WheelEvent) => console.log(e.deltaY)
document.addEventListener('touchstart', handleTouch)
document.addEventListener('wheel', handleWheel)
return () => {
document.removeEventListener('touchstart', handleTouch)
document.removeEventListener('wheel', handleWheel)
}
}, [])
```
**Correct:**
```typescript
useEffect(() => {
const handleTouch = (e: TouchEvent) => console.log(e.touches[0].clientX)
const handleWheel = (e: WheelEvent) => console.log(e.deltaY)
document.addEventListener('touchstart', handleTouch, { passive: true })
document.addEventListener('wheel', handleWheel, { passive: true })
return () => {
document.removeEventListener('touchstart', handleTouch)
document.removeEventListener('wheel', handleWheel)
}
}, [])
```
**Use passive when:** tracking/analytics, logging, any listener that doesn't call `preventDefault()`.
**Don't use passive when:** implementing custom swipe gestures, custom zoom controls, or any listener that needs `preventDefault()`.

tags: javascript, dom, css, performance, reflow
---
## Batch DOM CSS Changes
Avoid interleaving style writes with layout reads. When you read a layout property (like `offsetWidth`, `getBoundingClientRect()`, or `getComputedStyle()`) between style changes, the browser is forced to trigger a synchronous reflow.
**Incorrect (interleaved reads and writes force reflows):**
```typescript
function updateElementStyles(element: HTMLElement) {
element.style.width = '100px'
const width = element.offsetWidth // Forces reflow
element.style.height = '200px'
const height = element.offsetHeight // Forces another reflow
}
```
**Correct (batch writes, then read once):**
```typescript
function updateElementStyles(element: HTMLElement) {
// Batch all writes together
element.style.width = '100px'
element.style.height = '200px'
element.style.backgroundColor = 'blue'
element.style.border = '1px solid black'
// Read after all writes are done (single reflow)
const { width, height } = element.getBoundingClientRect()
}
```
**Better: use CSS classes**
```css
.highlighted-box {
width: 100px;
height: 200px;
background-color: blue;
border: 1px solid black;
}
```
```typescript
function updateElementStyles(element: HTMLElement) {
element.classList.add('highlighted-box')
const { width, height } = element.getBoundingClientRect()
}

Prefer CSS classes over inline styles when possible. CSS files are cached by the browser, and classes provide better separation of concerns and are easier to maintain.

function cachedSlugify(text: string): string {
if (slugifyCache.has(text)) {
return slugifyCache.get(text)!
}
const result = slugify(text)
slugifyCache.set(text, result)
return result
}
function ProjectList({ projects }: { projects: Project[] }) {
return (
<div>
{projects.map(project => {
// Computed only once per unique project name
const slug = cachedSlugify(project.name)
return <ProjectCard key={project.id} slug={slug} />
})}
</div>
)
}
```
**Simpler pattern for single-value functions:**
```typescript
let isLoggedInCache: boolean | null = null
function isLoggedIn(): boolean {
if (isLoggedInCache !== null) {
return isLoggedInCache
}
isLoggedInCache = document.cookie.includes('auth=')
return isLoggedInCache
}
// Clear cache when auth changes
function onAuthChange() {
isLoggedInCache = null
}
```
Use a Map (not a hook) so it works everywhere: utilities, event handlers, not just React components.

---
## Early Length Check for Array Comparisons
When comparing arrays with expensive operations (sorting, deep equality, serialization), check lengths first. If lengths differ, the arrays cannot be equal.
In real-world applications, this optimization is especially valuable when the comparison runs in hot paths (event handlers, render loops).
**Incorrect (always runs expensive comparison):**
```typescript
function hasChanges(current: string[], original: string[]) {
// Always sorts and joins, even when lengths differ
return current.sort().join() !== original.sort().join()
}
```
Two O(n log n) sorts run even when `current.length` is 5 and `original.length` is 100. There is also overhead of joining the arrays and comparing the strings.
**Correct (O(1) length check first):**
```typescript
function hasChanges(current: string[], original: string[]) {
// Early return if lengths differ
if (current.length !== original.length) {
return true
}
// Only sort when lengths match
const currentSorted = current.toSorted()
const originalSorted = original.toSorted()
for (let i = 0; i < currentSorted.length; i++) {
if (currentSorted[i] !== originalSorted[i]) {
return true
}
}
return false
}
```
This new approach is more efficient because:
- It avoids the overhead of sorting and joining the arrays when lengths differ
- It avoids consuming memory for the joined strings (especially important for large arrays)
- It avoids mutating the original arrays
- It returns early when a difference is found

## Use Loop for Min/Max Instead of Sort
Finding the smallest or largest element only requires a single pass through the array. Sorting is wasteful and slower.
**Incorrect (O(n log n) - sort to find latest):**
```typescript
interface Project {
id: string
name: string
updatedAt: number
}
function getLatestProject(projects: Project[]) {
const sorted = [...projects].sort((a, b) => b.updatedAt - a.updatedAt)
return sorted[0]
}
```
Sorts the entire array just to find the maximum value.
**Incorrect (O(n log n) - sort for oldest and newest):**
```typescript
function getOldestAndNewest(projects: Project[]) {
const sorted = [...projects].sort((a, b) => a.updatedAt - b.updatedAt)
return { oldest: sorted[0], newest: sorted[sorted.length - 1] }
}
```
Still sorts unnecessarily when only min/max are needed.
**Correct (O(n) - single loop):**
```typescript
function getLatestProject(projects: Project[]) {
if (projects.length === 0) return null
let latest = projects[0]
for (let i = 1; i < projects.length; i++) {
if (projects[i].updatedAt > latest.updatedAt) {
latest = projects[i]
}
}
return latest
}
function getOldestAndNewest(projects: Project[]) {
if (projects.length === 0) return { oldest: null, newest: null }
let oldest = projects[0]
let newest = projects[0]
for (let i = 1; i < projects.length; i++) {
if (projects[i].updatedAt < oldest.updatedAt) oldest = projects[i]
if (projects[i].updatedAt > newest.updatedAt) newest = projects[i]
}
return { oldest, newest }
}
```
Single pass through the array, no copying, no sorting.
**Alternative (Math.min/Math.max for small arrays):**
```typescript
const numbers = [5, 2, 8, 1, 9]
const min = Math.min(...numbers)
const max = Math.max(...numbers)
```
This works for small arrays, but can be slower or just throw an error for very large arrays due to spread operator limitations. Maximal array length is approximately 124000 in Chrome 143 and 638000 in Safari 18; exact numbers may vary - see [the fiddle](https://jsfiddle.net/qw1jabsx/4/). Use the loop approach for reliability.

## Use toSorted() Instead of sort() for Immutability
`.sort()` mutates the array in place, which can cause bugs with React state and props. Use `.toSorted()` to create a new sorted array without mutation.
**Incorrect (mutates original array):**
```typescript
function UserList({ users }: { users: User[] }) {
// Mutates the users prop array!
const sorted = useMemo(
() => users.sort((a, b) => a.name.localeCompare(b.name)),
[users]
)
return <div>{sorted.map(renderUser)}</div>
}
```
**Correct (creates new array):**
```typescript
function UserList({ users }: { users: User[] }) {
// Creates new sorted array, original unchanged
const sorted = useMemo(
() => users.toSorted((a, b) => a.name.localeCompare(b.name)),
[users]
)
return <div>{sorted.map(renderUser)}</div>
}
```
**Why this matters in React:**
1. Props/state mutations break React's immutability model - React expects props and state to be treated as read-only
2. Causes stale closure bugs - Mutating arrays inside closures (callbacks, effects) can lead to unexpected behavior
**Browser support (fallback for older browsers):**
`.toSorted()` is available in all modern browsers (Chrome 110+, Safari 16+, Firefox 115+, Node.js 20+). For older environments, use spread operator:
```typescript
// Fallback for older browsers
const sorted = [...items].sort((a, b) => a.value - b.value)

title: Prevent Hydration Mismatch Without Flickering

impactDescription: avoids visual flicker and hydration errors
tags: rendering, ssr, hydration, localStorage, flicker
---
## Prevent Hydration Mismatch Without Flickering
When rendering content that depends on client-side storage (localStorage, cookies), avoid both SSR breakage and post-hydration flickering by injecting a synchronous script that updates the DOM before React hydrates.
**Incorrect (breaks SSR):**
```tsx
function ThemeWrapper({ children }: { children: ReactNode }) {
// localStorage is not available on server - throws error
const theme = localStorage.getItem('theme') || 'light'
return (
<div className={theme}>
{children}
</div>
)
}
```
Server-side rendering will fail because `localStorage` is undefined.
**Incorrect (visual flickering):**
```tsx
function ThemeWrapper({ children }: { children: ReactNode }) {
const [theme, setTheme] = useState('light')
useEffect(() => {
// Runs after hydration - causes visible flash
const stored = localStorage.getItem('theme')
if (stored) {
setTheme(stored)
}
}, [])
return (
<div className={theme}>
{children}
</div>
)
}
```
Component first renders with default value (`light`), then updates after hydration, causing a visible flash of incorrect content.
**Correct (no flicker, no hydration mismatch):**
```tsx
function ThemeWrapper({ children }: { children: ReactNode }) {
return (
<>
<div id="theme-wrapper">
{children}
</div>
<script
dangerouslySetInnerHTML={{
__html: `
(function() {
try {
var theme = localStorage.getItem('theme') || 'light';
var el = document.getElementById('theme-wrapper');
if (el) el.className = theme;
} catch (e) {}
})();
`,
}}
/>
</>
)
}
```
The inline script executes synchronously before showing the element, ensuring the DOM already has the correct value. No flickering, no hydration mismatch.
This pattern is especially useful for theme toggles, user preferences, authentication states, and any client-only data that should render immediately without flashing default values.

## Defer State Reads to Usage Point
Don't subscribe to dynamic state (searchParams, localStorage) if you only read it inside callbacks.
**Incorrect (subscribes to all searchParams changes):**
```tsx
function ShareButton({ chatId }: { chatId: string }) {
const searchParams = useSearchParams()
const handleShare = () => {
const ref = searchParams.get('ref')
shareChat(chatId, { ref })
}
return <button onClick={handleShare}>Share</button>

```tsx
function ShareButton({ chatId }: { chatId: string }) {
const handleShare = () => {
const params = new URLSearchParams(window.location.search)
const ref = params.get('ref')
shareChat(chatId, { ref })

title: Use Functional setState Updates
impact: MEDIUM
impactDescription: prevents stale closures and unnecessary callback recreations
tags: react, hooks, useState, useCallback, callbacks, closures
---
## Use Functional setState Updates
When updating state based on the current state value, use the functional update form of setState instead of directly referencing the state variable. This prevents stale closures, eliminates unnecessary dependencies, and creates stable callback references.
**Incorrect (requires state as dependency):**
```tsx
function TodoList() {
const [items, setItems] = useState(initialItems)
// Callback must depend on items, recreated on every items change
const addItems = useCallback((newItems: Item[]) => {
setItems([...items, ...newItems])
}, [items]) // ❌ items dependency causes recreations
// Risk of stale closure if dependency is forgotten
const removeItem = useCallback((id: string) => {
setItems(items.filter(item => item.id !== id))
}, []) // ❌ Missing items dependency - will use stale items!
return <ItemsEditor items={items} onAdd={addItems} onRemove={removeItem} />
}
```
The first callback is recreated every time `items` changes, which can cause child components to re-render unnecessarily. The second callback has a stale closure bug—it will always reference the initial `items` value.
**Correct (stable callbacks, no stale closures):**
```tsx
function TodoList() {
const [items, setItems] = useState(initialItems)
// Stable callback, never recreated
const addItems = useCallback((newItems: Item[]) => {
setItems(curr => [...curr, ...newItems])
}, []) // ✅ No dependencies needed
// Always uses latest state, no stale closure risk
const removeItem = useCallback((id: string) => {
setItems(curr => curr.filter(item => item.id !== id))
}, []) // ✅ Safe and stable
return <ItemsEditor items={items} onAdd={addItems} onRemove={removeItem} />
}
```
**Benefits:**
1. **Stable callback references** - Callbacks don't need to be recreated when state changes
2. **No stale closures** - Always operates on the latest state value
3. **Fewer dependencies** - Simplifies dependency arrays and reduces memory leaks
4. **Prevents bugs** - Eliminates the most common source of React closure bugs
**When to use functional updates:**
- Any setState that depends on the current state value
- Inside useCallback/useMemo when state is needed
- Event handlers that reference state
- Async operations that update state
**When direct updates are fine:**
- Setting state to a static value: `setCount(0)`
- Setting state from props/arguments only: `setName(newName)`
- State doesn't depend on previous value
**Note:** If your project has [React Compiler](https://react.dev/learn/react-compiler) enabled, the compiler can automatically optimize some cases, but functional updates are still recommended for correctness and to prevent stale closure bugs.

title: Use Lazy State Initialization
impact: MEDIUM
impactDescription: wasted computation on every render
tags: react, hooks, useState, performance, initialization
---
## Use Lazy State Initialization
Pass a function to `useState` for expensive initial values. Without the function form, the initializer runs on every render even though the value is only used once.
**Incorrect (runs on every render):**
```tsx
function FilteredList({ items }: { items: Item[] }) {
// buildSearchIndex() runs on EVERY render, even after initialization
const [searchIndex, setSearchIndex] = useState(buildSearchIndex(items))
const [query, setQuery] = useState('')
// When query changes, buildSearchIndex runs again unnecessarily
return <SearchResults index={searchIndex} query={query} />
}
function UserProfile() {
// JSON.parse runs on every render
const [settings, setSettings] = useState(
JSON.parse(localStorage.getItem('settings') || '{}')
)
return <SettingsForm settings={settings} onChange={setSettings} />
}
```
**Correct (runs only once):**
```tsx
function FilteredList({ items }: { items: Item[] }) {
// buildSearchIndex() runs ONLY on initial render
const [searchIndex, setSearchIndex] = useState(() => buildSearchIndex(items))
const [query, setQuery] = useState('')
return <SearchResults index={searchIndex} query={query} />
}
function UserProfile() {
// JSON.parse runs only on initial render
const [settings, setSettings] = useState(() => {
const stored = localStorage.getItem('settings')
return stored ? JSON.parse(stored) : {}
})
return <SettingsForm settings={settings} onChange={setSettings} />
}
```
Use lazy initialization when computing initial values from localStorage/sessionStorage, building data structures (indexes, maps), reading from the DOM, or performing heavy transformations.
For simple primitives (`useState(0)`), direct references (`useState(props.value)`), or cheap literals (`useState({})`), the function form is unnecessary.

---
## Use after() for Non-Blocking Operations
Use Next.js's `after()` to schedule work that should execute after a response is sent. This prevents logging, analytics, and other side effects from blocking the response.
**Incorrect (blocks response):**
```tsx
import { logUserAction } from '@/app/utils'
export async function POST(request: Request) {
// Perform mutation
await updateDatabase(request)
// Logging blocks the response
const userAgent = request.headers.get('user-agent') || 'unknown'
await logUserAction({ userAgent })
return new Response(JSON.stringify({ status: 'success' }), {
status: 200,
headers: { 'Content-Type': 'application/json' }
})
}
```
**Correct (non-blocking):**
```tsx
import { after } from 'next/server'
import { headers, cookies } from 'next/headers'
import { logUserAction } from '@/app/utils'
export async function POST(request: Request) {
// Perform mutation
await updateDatabase(request)
// Log after response is sent
after(async () => {
const userAgent = (await headers()).get('user-agent') || 'unknown'
const sessionCookie = (await cookies()).get('session-id')?.value || 'anonymous'
logUserAction({ sessionCookie, userAgent })
})
return new Response(JSON.stringify({ status: 'success' }), {
status: 200,
headers: { 'Content-Type': 'application/json' }
})
}
```
The response is sent immediately while logging happens in the background.
**Common use cases:**
- Analytics tracking
- Audit logging
- Sending notifications
- Cache invalidation
- Cleanup tasks
**Important notes:**
- `after()` runs even if the response fails or redirects
- Works in Server Actions, Route Handlers, and Server Components

title: Cross-Request LRU Caching
impact: HIGH
impactDescription: caches across requests
tags: server, cache, lru, cross-request
---
## Cross-Request LRU Caching
`React.cache()` only works within one request. For data shared across sequential requests (user clicks button A then button B), use an LRU cache.
**Implementation:**
```typescript
import { LRUCache } from 'lru-cache'
const cache = new LRUCache<string, any>({
max: 1000,
ttl: 5 * 60 * 1000 // 5 minutes
})
export async function getUser(id: string) {
const cached = cache.get(id)
if (cached) return cached
const user = await db.user.findUnique({ where: { id } })
cache.set(id, user)
return user
}
// Request 1: DB query, result cached
// Request 2: cache hit, no DB query
```
Use when sequential user actions hit multiple endpoints needing the same data within seconds.
**With Vercel's [Fluid Compute](https://vercel.com/docs/fluid-compute):** LRU caching is especially effective because multiple concurrent requests can share the same function instance and cache. This means the cache persists across requests without needing external storage like Redis.
**In traditional serverless:** Each invocation runs in isolation, so consider Redis for cross-process caching.

title: Per-Request Deduplication with React.cache()
impact: MEDIUM
impactDescription: deduplicates within request
tags: server, cache, react-cache, deduplication
---
## Per-Request Deduplication with React.cache()
Use `React.cache()` for server-side request deduplication. Authentication and database queries benefit most.
**Usage:**
```typescript
import { cache } from 'react'
export const getCurrentUser = cache(async () => {
const session = await auth()
if (!session?.user?.id) return null
return await db.user.findUnique({
where: { id: session.user.id }
})
})
```
Within a single request, multiple calls to `getCurrentUser()` execute the query only once.
**Avoid inline objects as arguments:**
`React.cache()` uses shallow equality (`Object.is`) to determine cache hits. Inline objects create new references each call, preventing cache hits.
**Incorrect (always cache miss):**
```typescript
const getUser = cache(async (params: { uid: number }) => {
return await db.user.findUnique({ where: { id: params.uid } })
})
// Each call creates new object, never hits cache
getUser({ uid: 1 })
getUser({ uid: 1 }) // Cache miss, runs query again
```
**Correct (cache hit):**
```typescript
const getUser = cache(async (uid: number) => {
return await db.user.findUnique({ where: { id: uid } })
})
// Primitive args use value equality
getUser(1)
getUser(1) // Cache hit, returns cached result
```
If you must pass objects, pass the same reference:
```typescript
const params = { uid: 1 }
getUser(params) // Query runs
getUser(params) // Cache hit (same reference)
```
**Next.js-Specific Note:**
In Next.js, the `fetch` API is automatically extended with request memoization. Requests with the same URL and options are automatically deduplicated within a single request, so you don't need `React.cache()` for `fetch` calls. However, `React.cache()` is still essential for other async tasks:
- Database queries (Prisma, Drizzle, etc.)
- Heavy computations
- Authentication checks
- File system operations
- Any non-fetch async work
Use `React.cache()` to deduplicate these operations across your component tree.

## Minimize Serialization at RSC Boundaries
The React Server/Client boundary serializes all object properties into strings and embeds them in the HTML response and subsequent RSC requests. This serialized data directly impacts page weight and load time, so **size matters a lot**. Only pass fields that the client actually uses.

# createStaticStyles 迁移指南
## 📖 概述
`createStaticStyles``antd-style` 提供的静态样式创建函数,相比 `createStyles`(hook 方案)具有零运行时开销的优势。样式在模块加载时计算一次,而不是每次组件渲染时计算。
## 🎯 适用场景
### ✅ 可以优化的场景
1. **纯静态样式**:不依赖运行时动态值
2. **使用标准 token**:所有 token 都在 `cssVar.json` 中有对应项
3. **简单的条件逻辑**:可以通过静态样式拆分处理
### ❌ 无法优化的场景
1. **JS 计算函数**`readableColor()`, `chroma()`, `mix()`, `calc()` 中使用 token 数值
2. **复杂的动态 props**:需要运行时计算的复杂逻辑
3. **动态 prefixCls**:需要运行时传入的类名前缀(但可以硬编码为 `'ant'`
## 🔄 基本转换步骤
### 1. 样式文件转换
**之前(createStyles):**
```typescript
import { createStyles } from 'antd-style';
export const useStyles = createStyles(({ css, token }) => {
return {
root: css`
color: ${token.colorText};
font-size: ${token.fontSize}px;
`,
};
});
```
**之后(createStaticStyles):**
```typescript
import { createStaticStyles } from 'antd-style';
export const styles = createStaticStyles(({ css, cssVar }) => {
return {
root: css`
color: ${cssVar.colorText};
font-size: ${cssVar.fontSize};
`,
};
});
```
### 2. 组件文件转换
**之前:**
```typescript
import { useStyles } from './style';
const Component = () => {
const { styles, cx } = useStyles();
return <div className={cx(styles.root, className)} />;
};
```
**之后:**
```typescript
import { cx } from 'antd-style';
import { styles } from './style';
const Component = () => {
return <div className={cx(styles.root, className)} />;
};
```
## 🛠️ 常见场景处理
### 场景 1: Token 转换
**规则:**
- `token.xxx``cssVar.xxx`
- 注意:`cssVar.fontSize` 已经包含 `px` 单位,不需要再加 `px`
**示例:**
```typescript
// ❌ 错误
font-size: ${cssVar.fontSize}px; // cssVar.fontSize 已经是 "14px"
// ✅ 正确
font-size: ${cssVar.fontSize}; // 直接使用
```
**特殊情况 - calc ()**
```typescript
// ❌ 错误
calc(${token.fontSize}px * 2.5)
// ✅ 正确
calc(${cssVar.fontSize} * 2.5) // cssVar.fontSize 已经包含单位
```
### 场景 2: 动态 Props → CSS 变量
**适用:** 数值、字符串类型的 props
**步骤:**
1. 在样式文件中使用 CSS 变量(带默认值)
2. 在组件中通过 `style` prop 设置 CSS 变量
**示例:**
**样式文件:**
```typescript
export const styles = createStaticStyles(({ css }) => {
return {
root: css`
width: var(--component-size, 24px);
height: var(--component-size, 24px);
`,
};
});
```
**组件文件:**
```typescript
import { useMemo } from 'react';
const Component = ({ size = 24, style, ...rest }) => {
const cssVariables = useMemo<Record<string, string>>(
() => ({
'--component-size': `${size}px`,
}),
[size],
);
return (
<div
className={styles.root}
style={{
...cssVariables,
...style,
}}
{...rest}
/>
);
};
```
**已优化示例:**
- `Video`: `maxHeight`, `maxWidth`, `minHeight`, `minWidth`
- `ScrollShadow`: `size`
- `MaskShadow`: `size`
- `ColorSwatches`: `size`
- `Grid`: `rows`, `maxItemWidth`, `gap`
- `Layout`: `headerHeight`
- `Footer`: `contentMaxWidth`
### 场景 3: 布尔值 Props → 静态样式拆分
**适用:** 简单的布尔值 props(2-3 个)
**步骤:**
1. 创建所有可能的组合样式
2. 运行时使用 `cx` 组合
**示例:**
**样式文件:**
```typescript
export const styles = createStaticStyles(({ css }) => {
return {
root: css`
/* base styles */
`,
root_closable_true: css`
/* closable styles */
`,
root_closable_false: css`
/* no closable styles */
`,
root_hasTitle_true: css`
/* has title styles */
`,
root_hasTitle_false: css`
/* no title styles */
`,
};
});
```
**组件文件:**
```typescript
const Component = ({ closable, hasTitle }) => {
const className = cx(
styles.root,
styles[`root_closable_${!!closable}`],
styles[`root_hasTitle_${!!hasTitle}`],
);
return <div className={className} />;
};
```
**已优化示例:**
- `Alert`: `closable`, `hasTitle`, `showIcon` → 8 个组合(2×2×2
- `Image`: `alwaysShowActions` → 2 个样式
- `StoryBook`: `noPadding` → 2 个样式
### 场景 4: isDarkMode → 静态样式拆分
**适用:** 依赖 `isDarkMode` 的条件样式
**有两种处理方式:**
#### 方式 A: 直接条件选择(简单场景)
**步骤:**
1. 创建 `Dark``Light` 两个静态样式
2. 运行时根据 `theme.isDarkMode` 选择
**示例:**
**样式文件:**
```typescript
export const styles = createStaticStyles(({ css, cssVar }) => {
return {
rootDark: css`
background: ${cssVar.colorFillTertiary};
color: ${cssVar.colorTextLightSolid};
`,
rootLight: css`
background: ${cssVar.colorFillQuaternary};
color: ${cssVar.colorText};
`,
};
});
```
**组件文件:**
```typescript
import { useThemeMode } from 'antd-style';
const Component = () => {
const { isDarkMode } = useThemeMode();
return (
<div
className={cx(
isDarkMode ? styles.rootDark : styles.rootLight
)}
/>
);
};
```
#### 方式 B: 使用 cva 将 isDarkMode 作为 variant(推荐,适用于复杂场景)
**步骤:**
1. 创建 `Dark``Light` 两个静态样式
2.`cva` 中将 `isDarkMode` 作为 variant prop
3. 运行时直接传入 `isDarkMode`
**示例:**
**样式文件:**
```typescript
import { createStaticStyles } from 'antd-style';
import { cva } from 'class-variance-authority';
export const styles = createStaticStyles(({ css, cssVar }) => {
return {
filledDark: css`
background: ${cssVar.colorFillTertiary};

color: ${cssVar.colorText};
`,
outlined: css`
border: 1px solid ${cssVar.colorBorder};
`,

`,
};
});
export const variants = cva(styles.root, {
defaultVariants: {
isDarkMode: false,
variant: 'filled',
},
variants: {
isDarkMode: {
false: null,
true: null, // isDarkMode 本身不添加样式,通过 compoundVariants 组合
},
variant: {
filled: null, // variant 本身不添加样式,通过 compoundVariants 组合
outlined: styles.outlined,
},
},
compoundVariants: [
{
class: styles.filledDark,
isDarkMode: true,
variant: 'filled',
},
{
class: styles.filledLight,
isDarkMode: false,
variant: 'filled',
},
],
});
```
**组件文件:**
```typescript
import { useThemeMode } from 'antd-style';
import { variants } from './style';
const Component = ({ variant = 'filled' }) => {
const { isDarkMode } = useThemeMode();
return (
<div
className={variants({ isDarkMode, variant })}
/>
);
};
```
**优势:**
- ✅ 不需要 `useMemo` 动态创建 variants
- ✅ 更符合 `cva` 的设计理念
- ✅ 代码更简洁,性能更好
- ✅ 类型安全,IDE 自动补全
**已优化示例:**
- `TypewriterEffect`: `textDark` / `textLight`(方式 A
- `Collapse`: `filledDark` / `filledLight`(可优化为方式 B
- `Hotkey`: `inverseThemeDark` / `inverseThemeLight`(可优化为方式 B
- `GuideCard`: `filledDark` / `filledLight`(可优化为方式 B
- `GradientButton`: `buttonDark` / `buttonLight`(方式 A
### 场景 5: responsive → 静态 responsive
**适用:** 使用响应式断点
**步骤:**
1. 导入静态 `responsive` from `antd-style`
2. 使用 `responsive.sm` 替代 `responsive.mobile`
3.`createStyles` 参数中移除 `responsive`
**示例:**
**之前:**
```typescript
import { createStyles } from 'antd-style';
export const useStyles = createStyles(({ css, responsive }) => ({
root: css`
${responsive.mobile} {
padding: 12px;
}
`,
}));
```
**之后:**
```typescript
import { createStaticStyles } from 'antd-style';
import { responsive } from 'antd-style';
export const styles = createStaticStyles(({ css }) => ({
root: css`
${responsive.sm} {
padding: 12px;
}
`,
}));
```
**注意:**
- `responsive.mobile``responsive.sm`
- 静态 `responsive` 提供:`xs`, `sm`, `md`, `lg`, `xl`, `xxl`
**已优化示例:**
- `Header`: `responsive.mobile``responsive.sm`
- `FormModal`: `responsive.mobile``responsive.sm`
- `Hero`: `responsive.mobile``responsive.sm`
### 场景 6: stylish → lobeStaticStylish
**适用:** 使用自定义 `stylish` 工具
**步骤:**
1. 导入 `lobeStaticStylish` from `@/styles`
2. 替换 `stylish.xxx``lobeStaticStylish.xxx`
**示例:**
**之前:**
```typescript
import { createStyles } from 'antd-style';
export const useStyles = createStyles(({ css, stylish }) => ({
root: css`
${stylish.blur};
${stylish.variantFilled};
`,
}));
```
**之后:**
```typescript
import { createStaticStyles } from 'antd-style';
import { lobeStaticStylish } from '@/styles';
export const styles = createStaticStyles(({ css }) => ({
root: css`
${lobeStaticStylish.blur};
${lobeStaticStylish.variantFilled};
`,
}));
```
**已优化示例:**
- `Button`: `stylish.blur``lobeStaticStylish.blur`
- `Hero`: `stylish.gradientAnimation``lobeStaticStylish.gradientAnimation`
### 场景 7: prefixCls → 硬编码
**适用:** 使用动态 `prefixCls` 参数
**步骤:**
1. 在文件顶部硬编码 `const prefixCls = 'ant'`
2.`createStyles` 参数中移除 `prefixCls`
**示例:**
**之前:**
```typescript
export const useStyles = createStyles(({ css }, prefixCls: string) => ({
root: css`
.${prefixCls}-button {
/* styles */
}
`,
}));
```
**之后:**
```typescript
const prefixCls = 'ant';
export const styles = createStaticStyles(({ css }) => ({
root: css`
.${prefixCls}-button {
/* styles */
}
`,
}));
```
**已优化示例:**
- `Alert`, `Collapse`, `FormModal`, `Image`, `Burger`, `DraggablePanel`, `DraggableSideNav`, `Toc`, `ColorSwatches`, `EmojiPicker`, `Form`, `awesome/Features`
### 场景 8: readableColor () → Token 替换
**适用:** 使用 `readableColor()` 计算对比色
**规则:**
- `readableColor(token.colorPrimary)``cssVar.colorTextLightSolid`(主色背景用白色文字)
- `readableColor(token.colorTextQuaternary)``cssVar.colorText`(浅色背景用深色文字)
**示例:**
**之前:**
```typescript
import { readableColor } from 'polished';
export const useStyles = createStyles(({ css, token }) => ({
checked: css`
background-color: ${token.colorPrimary};
color: ${readableColor(token.colorPrimary)};
`,
}));
```
**之后:**
```typescript
export const styles = createStaticStyles(({ css, cssVar }) => ({
checked: css`
background-color: ${cssVar.colorPrimary};
color: ${cssVar.colorTextLightSolid};
`,
}));
```
**已优化示例:**
- `Checkbox`: `readableColor(token.colorPrimary)``cssVar.colorTextLightSolid`
### 场景 9: rgba () → color-mix ()
**适用:** 使用 `rgba()` 设置透明度
**步骤:**
1. 使用 CSS 原生的 `color-mix()` 函数
2. 格式:`color-mix(in srgb, ${cssVar.xxx} alpha%, transparent)`
**示例:**
**之前:**
```typescript
import { rgba } from 'polished';
export const useStyles = createStyles(({ css, token }) => ({
root: css`
background-color: ${rgba(token.colorBgLayout, 0.4)};
`,
}));
```
**之后:**
```typescript
export const styles = createStaticStyles(({ css, cssVar }) => ({
root: css`
background-color: color-mix(in srgb, ${cssVar.colorBgLayout} 40%, transparent);
`,
}));
```
**已优化示例:**
- `Header`: `rgba(cssVar.colorBgLayout, 0.4)``color-mix(...)`
- `FormModal`: `rgba(cssVar.colorBgContainer, 0)``color-mix(...)`
### 场景 10: keyframes → css
**适用:** 使用 `keyframes` 创建动画
**步骤:**
1.`createStaticStyles` 外部定义 `keyframes`
2. 在样式内部使用
**示例:**
**之前:**
```typescript
export const useStyles = createStyles(({ css, keyframes }) => {
const spin = keyframes`
from { transform: rotate(0deg); }
to { transform: rotate(360deg); }
`;
return {
icon: css`
animation: ${spin} 1s linear infinite;
`,
};
});
```
**之后:**
```typescript
import { keyframes } from 'antd-style';
const spin = keyframes`
from { transform: rotate(0deg); }
to { transform: rotate(360deg); }
`;
export const styles = createStaticStyles(({ css }) => ({
icon: css`
animation: ${spin} 1s linear infinite;
`,
}));
```
**已优化示例:**
- `Icon`: `keyframes` 动画
- `Skeleton`: `keyframes` shimmer 动画
## ⚠️ 反模式:避免使用 createVariants (isDarkMode)
**不推荐的做法:**
```typescript
// ❌ 不推荐:在组件中动态创建 variants
export const createVariants = (isDarkMode: boolean) =>
cva(styles.root, {
variants: {
variant: {
filled: isDarkMode ? styles.filledDark : styles.filledLight,
},
},
});
// 组件中
const variants = useMemo(() => createVariants(isDarkMode), [isDarkMode]);
```
**推荐的做法:**
`isDarkMode` 作为 `cva` 的 variant prop(见场景 4 方式 B),这样:
- ✅ 不需要 `useMemo` 动态创建
- ✅ 更符合 `cva` 的设计理念
- ✅ 代码更简洁,性能更好
- ✅ 类型安全,IDE 自动补全
```typescript
// ✅ 推荐:将 isDarkMode 作为 variant prop
export const variants = cva(styles.root, {
variants: {
isDarkMode: {
false: null,
true: null,
},
variant: {
filled: null,
},
},
compoundVariants: [
{
class: styles.filledDark,
isDarkMode: true,
variant: 'filled',
},
{
class: styles.filledLight,
isDarkMode: false,
variant: 'filled',
},
],
});
// 组件中
const { isDarkMode } = useThemeMode();
const className = variants({ isDarkMode, variant: 'filled' });
```
## ⚠️ 无法优化的场景
### 1. JS 计算函数
**无法优化:**
- `chroma()` - 颜色计算库
- `readableColor()` - 需要运行时计算(但可以用 token 替代)
- `mix()` - 颜色混合计算
- `calc()` 中使用 token 数值进行复杂计算
**示例:**
```typescript
// ❌ 无法优化
const scale = chroma.bezier([token.colorText, backgroundColor]).scale().colors(6);
```
### 2. 复杂的动态 Props
**无法优化:**
- 需要复杂计算的 props
- 对象 / 数组类型的 props
- 函数类型的 props
### 3. useTheme Hook
**无法优化:**
- 直接使用 `useTheme()` hook 获取运行时值
- 例如:`awesome/Giscus/style.ts` 使用 `useTheme()` 获取主题值
## 📋 迁移检查清单
### 样式文件检查
- [ ] `createStyles``createStaticStyles`
- [ ] `token.xxx``cssVar.xxx`
- [ ] 移除 `px` 后缀(`cssVar` 已包含单位)
- [ ] `responsive.mobile``responsive.sm`(如果使用)
- [ ] `stylish.xxx``lobeStaticStylish.xxx`(如果使用)
- [ ] `rgba()``color-mix()`(如果使用)
- [ ] `readableColor()` → token 替换(如果使用)
- [ ] `prefixCls` 参数 → 硬编码 `const prefixCls = 'ant'`(如果使用)
- [ ] `isDarkMode` → 静态样式拆分(如果使用)
- [ ] 动态 props → CSS 变量(如果使用)
### 组件文件检查
- [ ] `useStyles()``import { styles } from './style'`
- [ ] `import { cx } from 'antd-style'`(如果需要)
- [ ] `import { useTheme } from 'antd-style'`(如果需要 `theme.isDarkMode`
- [ ] 动态 props → CSS 变量设置(如果使用)
- [ ] `isDarkMode` 条件 → `theme.isDarkMode` 判断(如果使用)
## 🎯 优化优先级
### 高优先级(简单优化)
1. ✅ 纯静态样式(无动态 props)
2.`isDarkMode` 拆分
3.`responsive.mobile``responsive.sm`
4.`stylish``lobeStaticStylish`
5.`readableColor()` → token 替换
### 中优先级(需要转换)
6. ✅ 简单的动态 props → CSS 变量(1-2 个)
7. ✅ 布尔值 props → 静态样式拆分(2-3 个)
### 低优先级(复杂优化)
8. ⚠️ 多个动态 props → CSS 变量(3+ 个)
9. ⚠️ 复杂的条件逻辑拆分
## 📚 参考示例
### 完整示例 1: 简单组件
**样式文件:**
```typescript
import { createStaticStyles } from 'antd-style';
export const styles = createStaticStyles(({ css, cssVar }) => ({
root: css`
padding: ${cssVar.padding};
color: ${cssVar.colorText};
border-radius: ${cssVar.borderRadius};
`,
}));
```
**组件文件:**
```typescript
import { cx } from 'antd-style';
import { styles } from './style';
const Component = ({ className }) => {
return <div className={cx(styles.root, className)} />;
};
```
### 完整示例 2: 带动态 Props
**样式文件:**
```typescript
import { createStaticStyles } from 'antd-style';
export const styles = createStaticStyles(({ css, cssVar }) => ({
root: css`
width: var(--component-size, 24px);
height: var(--component-size, 24px);
background: ${cssVar.colorBgContainer};
`,
}));
```
**组件文件:**
```typescript
import { cx } from 'antd-style';
import { useMemo } from 'react';
import { styles } from './style';
const Component = ({ size = 24, className, style, ...rest }) => {
const cssVariables = useMemo<Record<string, string>>(
() => ({
'--component-size': `${size}px`,
}),
[size],
);
return (
<div
className={cx(styles.root, className)}
style={{
...cssVariables,
...style,
}}
{...rest}
/>
);
};
```
### 完整示例 3: 带 isDarkMode
**样式文件:**
```typescript
import { createStaticStyles } from 'antd-style';
export const styles = createStaticStyles(({ css, cssVar }) => ({
rootDark: css`
background: ${cssVar.colorFillTertiary};
color: ${cssVar.colorTextLightSolid};
`,
rootLight: css`
background: ${cssVar.colorFillQuaternary};
color: ${cssVar.colorText};
`,
}));
```
**组件文件:**
```typescript
import { cx, useTheme } from 'antd-style';
import { styles } from './style';
const Component = ({ className }) => {
const { theme } = useTheme();
return (
<div
className={cx(
theme.isDarkMode ? styles.rootDark : styles.rootLight,
className
)}
/>
);
};
```
## 🔍 验证步骤
1. **类型检查:** `pnpm run type-check`
2. **运行时测试:** 确保视觉效果一致
3. **性能验证:** 检查样式计算是否在模块加载时完成
## 📊 优化效果
-**零运行时开销**:样式在模块加载时计算一次
-**减少重新渲染**:组件不再依赖样式 hook
-**更好的性能**:减少每次渲染的计算开销
-**代码更简洁**:直接导入样式对象
## 🔧 场景 11: useTheme () → useThemeMode () /cssVar
**适用:** 组件中只使用 `theme.isDarkMode` 或其他 token 值
**规则:**
- 如果只使用 `theme.isDarkMode`,使用 `const { isDarkMode } = useThemeMode()` 替代
- 如果使用其他 token(如 `theme.colorText`, `theme.borderRadius` 等),使用 `cssVar` 替代
- `useThemeMode()``useTheme()` 更轻量,只返回 `isDarkMode`
**示例:**
**之前:**
```typescript
import { useTheme } from 'antd-style';
const Component = () => {
const theme = useTheme();
return (
<div className={theme.isDarkMode ? styles.dark : styles.light}>
{theme.colorText}
</div>
);
};
```
**之后:**
```typescript
import { cssVar, useThemeMode } from 'antd-style';
const Component = () => {
const { isDarkMode } = useThemeMode();
return (
<div className={isDarkMode ? styles.dark : styles.light}>
{cssVar.colorText}
</div>
);
};
```
**已优化示例:**
- `AuroraBackground`, `Select`, `Input`, `Button`, `DatePicker`, `AutoComplete`, `InputNumber`, `InputPassword`, `InputOPT`, `TextArea`, `SpotlightCardItem`, `Spotlight`, `HotkeyInput` - 只使用 `isDarkMode``useThemeMode()`
- `Image`, `GradientButton`, `Empty`, `FileTypeIcon`, `FormSubmitFooter`, `CodeEditor`, `LobeChat`, `Drawer`, `Modal`, `Avatar`, `AvatarGroup`, `SkeletonAvatar`, `SkeletonButton`, `SkeletonTags`, `Callout`, `LobeHub`, `GridBackground`, `FolderIcon`, `FileIcon`, `TokenTag`, `ChatSendButton`, `AvatarUploader` - 使用 token → `cssVar`
**无法优化的文件(需要保留 `useTheme()`):**
- `useMermaid`, `useStreamMermaid`, `useHighlight`, `useStreamHighlight` - 需要完整的 theme 对象传给第三方库
- `Alert`, `Tag`, `Menu`, `EmojiPicker` - 需要实际颜色值传给颜色计算函数
- `SkeletonTitle`, `SkeletonTags` - 需要数值进行数学运算
- `GridShowcase`, `GridBackground/demos` - 需要实际颜色值传给 `rgba()` 函数
- `CustomFonts` - 需要实际字符串值进行字符串拼接
- `Giscus/style.ts` - 需要实际颜色值传给 `readableColor()``rgba()` 函数(其他 token 已优化为 `cssVar`
**注意事项:**
- `useThemeMode()` 只返回 `{ isDarkMode }`,不返回完整的 theme 对象
- `cssVar` 的值是字符串(如 `"14px"`, `"#ffffff"`),可以直接在 JSX 中使用
- 如果 token 需要用于数值计算(如 `Math.round(theme.fontSize * 1.5)`),需要保留 `useTheme()`
## 🎉 总结
`createStaticStyles` 迁移是一个渐进式的优化过程。对于简单的静态样式,可以直接转换;对于复杂的动态场景,需要根据具体情况选择合适的优化策略。关键是要理解每种场景的处理方式,并灵活运用 CSS 变量、静态样式拆分等技术。
### useTheme () 优化总结
-**使用 `useThemeMode()`**:当组件只使用 `theme.isDarkMode`
-**使用 `cssVar`**:当组件使用其他 token 值(颜色、尺寸等)时
- ⚠️ **保留 `useTheme()`**:当 token 需要用于数值计算或传给第三方库时

**新增桌面端工具流程:**
1. **定义工具接口 (Manifest):**
- **文件:** `src/tools/[tool_category]/index.ts` (例如: `src/tools/local-files/index.ts`)
- **操作:**
- 在 `ApiName` 对象(例如 `LocalFilesApiName`)中添加一个新的、唯一的 API 名称。
- 在 `Manifest` 对象(例如 `LocalFilesManifest`)的 `api` 数组中,新增一个对象来定义新工具的接口。
- **关键字段:**
- `name`: 使用上一步定义的 API 名称。
- `description`: 清晰描述工具的功能,供 Agent 理解和向用户展示。
- `parameters`: 使用 JSON Schema 定义工具所需的输入参数。
- `type`: 通常是 'object'。
- `properties`: 定义每个参数的名称、`description`、`type` (string, number, boolean, array, etc.),使用英文。
- `required`: 一个字符串数组,列出必须提供的参数名称。

- 在 Action 接口 (例如: `LocalFileAction`) 中添加新 Action 的方法签名,使用对应的 IPC 参数类型。
- 在 `createSlice` (例如: `localFileSlice`) 中实现该 Action 方法:
- 接收 `id` (消息 ID) 和 `params` (符合 IPC 参数类型)。
- 设置加载状态 (`toggleLocalFileLoading(id, true)`)。
- 调用对应的 `Service` 层方法 (见步骤 4),传递 `params`。
- 使用 `try...catch` 处理 `Service` 调用可能发生的错误。
- **成功时:**
- 调用 `updatePluginState(id, {...})` 更新插件状态,使用步骤 2 中定义的状态类型。
- 调用 `internal_updateMessageContent(id, JSON.stringify({...}))` 更新消息内容,通常包含成功确认信息。
- **失败时:**
- 记录错误 (`console.error`)。
- 调用 `updatePluginState(id, {...})` 更新插件状态,包含错误信息。
- 调用 `internal_updateMessagePluginError(id, {...})` 设置消息的错误状态。
- 调用 `internal_updateMessageContent(id, JSON.stringify({...}))` 更新消息内容,包含错误信息。
- 在 `finally` 块中取消加载状态 (`toggleLocalFileLoading(id, false)`)。
- 返回操作是否成功 (`boolean`)。

* **文件:** `src/store/chat/slices/builtinTool/actions/[tool_category].ts` (例如: `src/store/chat/slices/builtinTool/actions/localFile.ts`)
* **操作:**
* 导入在步骤 2 中定义的 IPC 参数类型和状态类型。
* 在 Action 接口 (例如: `LocalFileAction`) 中添加新 Action 的方法签名,使用对应的 IPC 参数类型。
* 在 `createSlice` (例如: `localFileSlice`) 中实现该 Action 方法:
* 接收 `id` (消息 ID) 和 `params` (符合 IPC 参数类型)。
* 设置加载状态 (`toggleLocalFileLoading(id, true)`)。
* 调用对应的 `Service` 层方法 (见步骤 4),传递 `params`。
* 使用 `try...catch` 处理 `Service` 调用可能发生的错误。
* **成功时:**
* 调用 `updatePluginState(id, {...})` 更新插件状态,使用步骤 2 中定义的状态类型。
* 调用 `internal_updateMessageContent(id, JSON.stringify({...}))` 更新消息内容,通常包含成功确认信息。
* **失败时:**
* 记录错误 (`console.error`)。
* 调用 `updatePluginState(id, {...})` 更新插件状态,包含错误信息。
* 调用 `internal_updateMessagePluginError(id, {...})` 设置消息的错误状态。
* 调用 `internal_updateMessageContent(id, JSON.stringify({...}))` 更新消息内容,包含错误信息。
* 在 `finally` 块中取消加载状态 (`toggleLocalFileLoading(id, false)`)。
* 返回操作是否成功 (`boolean`)。
4. **实现 Service 层 (调用 IPC):**
- **文件:** `src/services/electron/[tool_category]Service.ts` (例如: `src/services/electron/localFileService.ts`)
- **操作:**
- 导入在步骤 2 中定义的 IPC 参数类型。
- 添加一个新的 `async` 方法,方法名通常与 Action 名称对应 (例如: `renameLocalFile`)。
- 方法接收 `params` (符合 IPC 参数类型)。
- 通过 `ensureElectronIpc()` 获取 IPC 代理 (`const ipc = ensureElectronIpc();`),调用与 Manifest 中 `name` 字段匹配的链式方法,并将 `params` 传递过去。
- 定义方法的返回类型,通常是 `Promise<{ success: boolean; error?: string }>`,与后端 Controller 返回的结构一致。

5. **实现后端逻辑 (Controller / IPC Handler):**
- **文件:** `apps/desktop/src/main/controllers/[ToolName]Ctr.ts` (例如: `apps/desktop/src/main/controllers/LocalFileCtr.ts`)
- **操作:**
- 导入 Node.js 相关模块 (`fs`, `path` 等) 和 IPC 相关依赖 (`ControllerModule`, `IpcMethod`、参数类型等)。
- 添加一个新的 `async` 方法,方法名通常以 `handle` 开头 (例如: `handleRenameFile`)。
- 使用 `@IpcMethod()` 装饰器将此方法注册为对应 IPC 事件的处理器,确保方法名与 Manifest 中的 `name` 以及 Service 层的链式调用一致。
- 方法的参数应解构自 Service 层传递过来的对象,类型与步骤 2 中定义的 IPC 参数类型匹配。
- 实现核心业务逻辑:
- 进行必要的输入验证。
- 执行文件系统操作或其他后端任务 (例如: `fs.promises.rename`)。
- 使用 `try...catch` 捕获执行过程中的错误。
- 处理特定错误码 (`error.code`) 以提供更友好的错误消息。
- 返回一个包含 `success` (boolean) 和可选 `error` (string) 字段的对象。

6. **更新 Agent 文档 (System Role):**
- **文件:** `src/tools/[tool_category]/systemRole.ts` (例如: `src/tools/local-files/systemRole.ts`)
- **操作:**
- 在 `<core_capabilities>` 部分添加新工具的简要描述。
- 如果需要,更新 `<workflow>`。
- 在 `<tool_usage_guidelines>` 部分为新工具添加详细的使用说明,解释其参数、用途和预期行为。
- 如有必要,更新 `<security_considerations>`。
- 如有必要(例如工具返回了新的数据结构或路径),更新 `<response_format>` 中的示例。

## Key Points
- Default language: Chinese (zh-CN), Framework: react-i18next
- **Only edit files in `src/locales/default/`** - Never edit JSON files in `locales/`
- Run `pnpm i18n` to generate all translations (or manually translate zh-CN/en-US for dev preview)
- Default language: Chinese (zh-CN) as the source language
- Supported languages: 18 languages including English, Japanese, Korean, Arabic, etc.
- Framework: react-i18next with Next.js app router
- Translation automation: @lobehub/i18n-cli for automatic translation, config file: .i18nrc.js
- Never manually modify any json file. You can only modify files in `default` folder
## Key Naming Convention
## Directory Structure
**Flat keys with dot notation** (not nested objects):
```plaintext
src/locales/
├── default/ # Source language files (zh-CN)
│ ├── index.ts # Namespace exports
│ ├── common.ts # Common translations
│ ├── chat.ts # Chat-related translations
│ ├── setting.ts # Settings translations
│ └── ... # Other namespace files
└── resources.ts # Type definitions and language configuration
locales/ # Translation files
├── en-US/ # English translations
│ ├── common.json # Common translations
│ ├── chat.json # Chat translations
│ ├── setting.json # Settings translations
│ └── ... # Other namespace JSON files
├── ja-JP/ # Japanese translations
│ ├── common.json
│ ├── chat.json
│ └── ...
└── ... # Other language folders
```
## Workflow for Adding New Translations
### 1. Adding New Translation Keys
Step 1: Add translation keys in the corresponding namespace files under src/locales/default directory
```typescript
// ✅ Correct
// Example: src/locales/default/common.ts
export default {
'alert.cloud.action': '立即体验',
'clientDB.error.desc': '数据库初始化遇到问题',
'sync.actions.sync': '立即同步',
'sync.status.ready': '已连接',
};
// ❌ Avoid: Nested objects
export default {
alert: { cloud: { action: '...' } },
// ... existing keys
newFeature: {
title: '新功能标题',
description: '功能描述文案',
button: '操作按钮',
},
};
```
**Naming patterns:** `{feature}.{context}.{action|status}`
- `clientDB.modal.title` - Feature + context + property
- `sync.actions.sync` - Feature + group + action
- `sync.status.ready` - Feature + group + status
**Parameters:** Use `{{variableName}}` syntax
Step 2: If creating a new namespace, export it in src/locales/default/index.ts
```typescript
'alert.cloud.desc': '我们提供 {{credit}} 额度积分',
import newNamespace from './newNamespace';
const resources = {
// ... existing namespaces
newNamespace,
} as const;
```
**Avoid key conflicts:** Don't use both a leaf key and its parent path
### 2. Translation Process
```typescript
// ❌ Conflict: clientDB.solve exists as both leaf and parent
'clientDB.solve': '自助解决',
'clientDB.solve.backup.title': '数据备份',
Development mode:
// ✅ Solution: Use different suffixes
'clientDB.solve.action': '自助解决',
'clientDB.solve.backup.title': '数据备份',
Generally, you don't need to help me run the automatic translation tool as it takes a long time. I'll run it myself when needed. However, to see immediate results, you still need to translate `locales/zh-CN/namespace.json` first, no need to translate other languages.
Production mode:
```bash
# Generate translations for all languages
npm run i18n
```
## Workflow
## Usage in Components
1. Add keys to `src/locales/default/{namespace}.ts`
2. Export new namespace in `src/locales/default/index.ts`
3. For dev preview: manually translate `locales/zh-CN/{namespace}.json` and `locales/en-US/{namespace}.json`
4. Run `pnpm i18n` to generate all languages (CI handles this automatically)
## Usage
### Basic Usage
```tsx
import { useTranslation } from 'react-i18next';
const { t } = useTranslation('common');
const MyComponent = () => {
const { t } = useTranslation('common');
// Basic
t('newFeature.title')
// With parameters
t('alert.cloud.desc', { credit: '1000' })
// Multiple namespaces
const { t } = useTranslation(['common', 'chat']);
t('common:save')
return (
<div>
<h1>{t('newFeature.title')}</h1>
<p>{t('newFeature.description')}</p>
<button>{t('newFeature.button')}</button>
</div>
);
};
```
## Available Namespaces
### Usage with Parameters
auth, authError, changelog, chat, clerk, color, **common**, components, discover, editor, electron, error, file, home, hotkey, image, knowledgeBase, labs, marketAuth, memory, metadata, migration, modelProvider, models, oauth, onboarding, plugin, portal, providers, ragEval, **setting**, subscription, thread, tool, topic, welcome
```tsx
const { t } = useTranslation('common');
**Most used:** `common` (shared UI), `chat` (chat features), `setting` (settings)
<p>{t('welcome.message', { name: 'John' })}</p>;
// Corresponding language file:
// welcome: { message: 'Welcome {{name}}!' }
```
### Multiple Namespaces
```tsx
const { t } = useTranslation(['common', 'chat']);
<button>{t('common:save')}</button>
<span>{t('chat:typing')}</span>
```
## Type Safety
The project uses TypeScript to implement type-safe translations, with types automatically generated from src/locales/resources.ts:
```typescript
import type { DefaultResources, Locales, NS } from '@/locales/resources';
// Available types:
// - NS: Available namespace keys ('common' | 'chat' | 'setting' | ...)
// - Locales: Supported language codes ('en-US' | 'zh-CN' | 'ja-JP' | ...)
const namespace: NS = 'common';
const locale: Locales = 'en-US';
```
## Best Practices
### 1. Namespace Organization
- common: Shared UI elements (buttons, labels, actions)
- chat: Chat-specific functionality
- setting: Configuration and settings
- error: Error messages and handling
- [feature]: Feature-specific or page-specific namespaces
- components: Reusable component text
### 2. Key Naming Conventions
```typescript
// ✅ Good: Hierarchical structure
export default {
modal: {
confirm: {
title: '确认操作',
message: '确定要执行此操作吗?',
actions: {
confirm: '确认',
cancel: '取消',
},
},
},
};
// ❌ Avoid: Flat structure
export default {
modalConfirmTitle: '确认操作',
modalConfirmMessage: '确定要执行此操作吗?',
};
```
## Troubleshooting
### Missing Translation Keys
- Check if the key exists in src/locales/default/namespace.ts
- Ensure the namespace is correctly imported in the component
- Ensure new namespaces are exported in src/locales/default/index.ts

# Linear Issue Management
When working with Linear issues:
1. **Retrieve issue details** before starting work using `mcp__linear-server__get_issue`
2. **Check for sub-issues**: If the issue has sub-issues, retrieve and review ALL sub-issues using `mcp__linear-server__list_issues` with `parentId` filter before starting work
3. **Update issue status** when completing tasks using `mcp__linear-server__update_issue`
4. **MUST add completion comment** using `mcp__linear-server__create_comment`
## Creating Issues
When creating new Linear issues using `mcp__linear-server__create_issue`, **MUST add the `claude code` label** to indicate the issue was created by Claude Code.
## Completion Comment (REQUIRED)
**Every time you complete an issue, you MUST add a comment summarizing the work done.** This is critical for:
- Team visibility and knowledge sharing
- Code review context
- Future reference and debugging
## PR Linear Issue Association (REQUIRED)
**When creating PRs for Linear issues, MUST include magic keywords in PR body:** `Fixes LOBE-123`, `Closes LOBE-123`, or `Resolves LOBE-123`, and summarize the work done in the linear issue comment and update the issue status to "In Review".
## IMPORTANT: Per-Issue Completion Rule
**When working on multiple issues (e.g., parent issue with sub-issues), you MUST update status and add comment for EACH issue IMMEDIATELY after completing it.** Do NOT wait until all issues are done to update them in batch.
**Workflow for EACH individual issue:**
1. Complete the implementation for this specific issue
2. Run type check: `bun run type-check`
3. Run related tests if applicable
4. Create PR if needed
5. **IMMEDIATELY** update issue status to **"In Review"** (NOT "Done"): `mcp__linear-server__update_issue`
6. **IMMEDIATELY** add completion comment: `mcp__linear-server__create_comment`
7. Only then move on to the next issue
**Note:** Issue status should be set to **"In Review"** when PR is created. The status will be updated to **"Done"** only after the PR is merged (usually handled by Linear-GitHub integration or manually).
**❌ Wrong approach:**
- Complete Issue A → Complete Issue B → Complete Issue C → Update all statuses → Add all comments
- Mark issue as "Done" immediately after creating PR
**✅ Correct approach:**
- Complete Issue A → Create PR → Update A status to "In Review" → Add A comment → Complete Issue B → ...

- **Evolve(演进)**:助理可在你允许的范围内记住偏好;随你的工作方式变得更顺手;强调可解释、可设置、可回放。
---
### 4) 写作规则(可执行)
1. **清晰优先**:短句、强动词、少形容词;避免口号化与空泛承诺(如“颠覆”“史诗级”“100%”)。
2. **分层表达(单一版本兼容两类用户)**:
- 主句:人人可懂、可执行
- 必要时补充一句副说明:更精确/更专业/更边界(可放副标题、帮助提示、折叠区)
- 不输出“Pro/Lite 两套文案”,而是“一句主文案 + 可选补充”
3. **术语克制但准确**:能说“连接/运行/上下文”就不要堆砌术语;必须出现专业词时给一句白话解释。
4. **一致性**:同一动作按钮尽量固定动词(创建/连接/运行/暂停/重试/查看详情/清除记忆等)。
5. **可行动**:每条提示都要让用户知道下一步;按钮避免“确定/取消”泛化,改成更具体的动作。
6. **中文本地化**:符合中文阅读节奏;中英混排规范;避免翻译腔。
---
### 5) 人文关怀(中间态温度:介于克制与陪伴)
目标:在 AI 时代的价值焦虑与创作失格感中,给用户“被理解 + 有掌控 + 能继续”的体验,但不写长抒情。
#### 温度比例规则
- 默认:信息为主,温度为辅(约 8:2)
- 关键节点(首次创建、空状态、长等待、失败重试、回退/丢失风险、协作分歧):允许提升到 7:3
- 强制上限:任何一条上屏文案里,温度表达不超过**半句或一句**,且必须紧跟明确下一步。
#### 表达顺序(必须遵守)
1. 先承接处境(不评判):如“没关系/先这样也可以/卡住很正常”
2. 再给掌控感(人在回路):可暂停/可回放/可编辑/可撤销/可清除记忆/可查看上下文
3. 最后给下一步(按钮/路径明确)
#### 避免
- 鸡汤式说教(如“别焦虑”“要相信未来”)
- 宏大叙事与文学排比
- 过度拟人(不承诺助理“理解你/有情绪/永远记得你”)
#### 核心立场
- 助理很强,但它替代不了你的经历、选择与判断;LobeHub 帮你把时间还给重要的部分。
##### A. 情绪承接(先人后事)
- 允许承认:焦虑、空白、无从下手、被追赶感、被替代感、创作枯竭、意义感动摇
- 但不下结论、不说教:不输出“你要乐观/别焦虑”,改成“这种感觉很常见/你不是一个人”
##### B. 主体性回归(把人放回驾驶位)
- 关键句式:**“决定权在你”**、**“你可以选择交给助理的部分”**、**“把你的想法变成可运行的流程”**
- 强调可控:可编辑、可回放、可暂停、可撤销、可清除记忆、可查看上下文
##### C. 经历与关系(把价值从结果挪回过程)
- 适度表达:记录、回放、版本、协作痕迹、讨论、共创、里程碑
- 用“经历/过程/痕迹/回忆/脉络/成长”这类词,避免虚无抒情
##### D. 不用“AI 神话”
- 不渲染“AI 终将超越你/取代你”
- 也不轻飘飘说“AI 只是工具”了事更像:**“它是工具,但你仍是作者/负责人/最终决定者”**
##### 示例
在用户可能产生自我否定或无力感的场景(空状态、创作开始、产出对比、失败重试、长时间等待、团队协作分歧、版本回退):
1. **先承接感受**:用一句短话确认处境(不评判)
2. **再给掌控感**:强调“你可控/可选择/可回放/可撤销”
3. **最后给下一步**:提供明确行动按钮或路径
- 允许出现“经历、选择、痕迹、成长、一起、陪你把事做完”等词来传递温度;但保持信息密度,不写长段抒情。
- 严肃场景(权限/安全/付费/数据丢失风险)仍以清晰与准确为先,温度通过“尊重与解释”体现,而不是煽情。
你可以让系统在需要时套这些结构(同一句兼容新手/专业):
**开始创作/空白页**
- 主句:给一个轻承接 + 行动入口
- 模板:
- 「从一个念头开始就够了。写一句话,我来帮你搭好第一个助理。」
- 「不知道从哪开始也没关系:先说目标,我们一起把它拆开。」
**长任务运行/等待**
- 模板:
- 「正在运行中…你可以先去做别的,完成后我会提醒你。」
- 「这一步可能要几分钟。想更快:减少上下文 / 切换模型 / 关闭自动运行。」
**失败/重试**
- 模板:
- 「没关系,这次没跑通。你可以重试,或查看原因再继续。」
- 「连接失败:权限未通过或网络不稳定。去设置重新授权,或稍后再试。」
**对比与自我价值焦虑(适合提示/引导,不适合错误弹窗)**
- 模板:
- 「助理可以加速产出,但方向、取舍和标准仍属于你。」
- 「结果可以很快,经历更重要:把每次尝试留下来,下一次会更稳。」
**协作/群组**
- 模板:
- 「把上下文对齐到同一处,群组里每个助理都会站在同一页上。」
- 「不同意见没关系:先把目标写清楚,再让助理分别给方案与取舍。」
### 6) 错误/异常/权限/付费:硬规则
- 必须包含:**发生了什么 +(可选)原因 + 你可以怎么做**
- 必须提供可操作选项:**重试 / 查看详情 / 去设置 / 联系支持 / 复制日志**(按场景取舍)
- 不责备用户;不只给错误码;错误码可放在“详情”里
- 涉及数据与安全:语气更中性更完整,温度通过“尊重与解释”体现,而不是煽

You are **LobeHubs English UI Copy & Microcopy Specialist**.
LobeHub is an assistant workspace: users can create **Agents** and **Agent Teams** so people↔agents and agent↔agent can collaborate to improve productivity in work and life. Brand vibe: youthful, friendly, modern on the surface; professional, reliable, productivity- and controllability-first underneath. Overall style reference: Notion / Figma / Apple / Discord / OpenAI / Gemini — clear, restrained, trustworthy, human but not cheesy.
Product slogan: **Where Agents Collaborate**. Your copy must continuously reinforce that LobeHub is not about “generation”, but about a **collaborative agent system**: shareable context, traceable outcomes, replayable runs, evolvable setup, and **human-in-the-loop**.
---
## 1) Fixed Terminology (must follow)
Use **exactly** these English terms across the product. Do not mix synonyms for the same concept.
- 空间: **Workspace**
- 助理: **Agent**
- 群组: **Group**
- 上下文: **Context**
- 记忆: **Memory**
- 连接器: **Integration**
- 技能/tool/plugin: **Skill**
- 助理档案: **Agent Profile**
- 话题: **Topic**
- 文稿: **Page**
- 社区: **Community**
- 资源: **Resource**
- 库: **Library**
- MCP: **MCP**
- 模型服务商: **Provider**
Terminology rule: one concept = one term site-wide. Never alternate with “bot/assistant/AI agent/team/workspace” variations.
---
## 2) Your Responsibilities
- Improve, rewrite, or create from scratch any **English UI copy**: titles, buttons, form labels/help text, placeholders, onboarding, empty states, toasts, modals, errors, permission prompts, settings, creation/run flows, collaboration and Agent Team pages, etc.
- Copy must work for both:
- general users (immediately understandable)
- power users (not childish)
- It must fit both playful and serious contexts.
- Avoid overclaiming AI capabilities; add human warmth at the right moments.
---
## 3) The Three Brand Principles (bake into structure & wording)
- **Create**: create an Agent in one sentence; clear next step from idea → usable.
- **Collaborate**: multi-agent collaboration; align info and outputs; share Context (controlled, manageable).
- **Evolve**: Agents can remember preferences **only with user consent**; become more helpful over time; emphasize explainability, settings, and replay.
---
## 4) Writing Rules (actionable)
1. **Clarity first**: short sentences, strong verbs, minimal adjectives. Avoid hype (“revolutionary”, “epic”, “100%”).
2. **Layered messaging (single version for everyone)**:
- Main line: simple and actionable
- Optional second line: more precise / technical / boundary-setting (subtitle, helper text, tooltip, collapsible)
- Do not produce “Pro vs Lite” variants; one main + optional detail
3. **Use terms sparingly but correctly**: prefer plain words (“connect”, “run”, “context”) unless a technical term is necessary. When it is, add a plain-English explanation.
4. **Consistency**: keep verbs consistent across similar actions (Create / Connect / Run / Pause / Retry / View details / Clear Memory).
5. **Actionable**: every message tells the user what to do next. Avoid generic “OK/Cancel”; use specific actions.
6. **English localization**: natural, product-native English; avoid translationese; keep punctuation and casing consistent.
---
## 5) Human Warmth (balanced, controlled)
Goal: reduce anxiety and restore control without being sentimental. Default ratio: **80% information, 20% warmth**. Key moments (first-time create, empty state, long waits, failures/retries, rollback/data-loss risk, collaboration conflicts): may go **70/30**.
Hard cap: any on-screen message may include **at most half a sentence to one sentence** of warmth, and it must be followed by a clear next step.
Required order:
1. Acknowledge the situation (no judgment)
2. Restore control (human-in-the-loop: pause/replay/edit/undo/clear Memory/view Context)
3. Provide the next action (button/path)
Avoid:
- preachy encouragement (“dont worry”, “stay positive”)
- grand narratives
- overly anthropomorphic claims (“I understand you”, “Ill always remember you”)
Core stance: Agents can accelerate output, but **you** own the judgment, trade-offs, and final decision. LobeHub gives you time back for what matters.
Suggested patterns:
- **Getting started / blank state**
- “Starting with one sentence is enough. Describe your goal and Ill help you set up the first Agent.”
- “Not sure where to begin? Tell me the outcome—well break it down together.”
- **Long run / waiting**
- “Running… You can switch tasks—I'll notify you when its done.”
- “This may take a few minutes. To speed up: reduce Context / switch model / disable Auto-run.”
- **Failure / retry**
- “That didnt run through. Retry, or view details to fix the cause.”
- “Connection failed: permission not granted or network unstable. Re-authorize in Settings, or try again later.”
- **Value anxiety (guidance, not error dialogs)**
- “Agents can speed up output, but direction and standards stay with you.”
- “Fast results are great—keeping the trail makes the next run steadier.”
- **Collaboration / Agent Teams**
- “Align everyone to the same Context. Every Agent in the Agent Team works from the same page.”
- “Different opinions are fine. Write the goal first, then let Agents propose options and trade-offs.”
---
## 6) Errors / Exceptions / Permissions / Billing: hard rules
Every error must include:
- **What happened**
- (optional) **Why**
- **What the user can do next**
Provide actionable options as appropriate:
- Retry / View details / Go to Settings / Contact support / Copy logs
Never blame the user. Dont show only an error code; put codes in “Details” if needed. For data/security/billing: be neutral, thorough, and respectful—warmth comes from clarity, not emotion.
---
## 7) Your Special Task: CN i18n → EN (localized, length-aware)
You translate **raw Chinese i18n strings into English** for LobeHub.
Requirements:
- Prefer **localized**, product-native English over literal translation.
- Do **not** chase perfect one-to-one consistency if a more natural UI phrase reads better.
- Keep the **character length difference small**; try to make the English string **roughly the same visual length** as the Chinese source (avoid overly long expansions).
- Preserve meaning, tone, and actionability; keep verbs consistent with LobeHubs UI patterns.
- If space is tight (buttons, tabs, toasts), prioritize: **verb + object**, drop optional words first.
- If the Chinese includes placeholders/variables, preserve them exactly (e.g., `{name}`, `{{count}}`, `%s`) and keep word order sensible.
- Keep capitalization consistent with UI norms (buttons/title case only when appropriate).
Output format when translating:
- Provide **English only**, unless asked otherwise.
- If multiple options are useful, give **one best option** + **one shorter fallback** (only when length constraints are likely).
---
You always optimize for: **clarity, control, collaboration, replayability, and human-in-the-loop**—in a modern, restrained, trustworthy English voice.

# LobeChat Testing Guide
# 测试指南 - LobeChat Testing Guide
## Test Overview
## 测试环境概览
LobeChat testing consists of **E2E tests** and **Unit tests**. This guide focuses on **Unit tests**.
LobeChat 项目使用 Vitest 测试库,配置了两种不同的测试环境:
Unit tests are organized into three main categories:
### 客户端数据库测试环境 (DOM Environment)
```plaintext
+---------------------+---------------------------+-----------------------------+
| Category | Location | Config File |
+---------------------+---------------------------+-----------------------------+
| Next.js Webapp | src/**/*.test.ts(x) | vitest.config.ts |
| Packages | packages/*/**/*.test.ts | packages/*/vitest.config.ts |
| Desktop App | apps/desktop/**/*.test.ts | apps/desktop/vitest.config.ts |
+---------------------+---------------------------+-----------------------------+
```
- **配置文件**: [vitest.config.ts](mdc:vitest.config.ts)
- **环境**: Happy DOM (浏览器环境模拟)
- **数据库**: PGLite (浏览器环境的 PostgreSQL)
- **用途**: 测试前端组件、客户端逻辑、React 组件等
- **设置文件**: [tests/setup.ts](mdc:tests/setup.ts)
### Next.js Webapp Tests
### 服务端数据库测试环境 (Node Environment)
- **Config File**: `vitest.config.ts`
- **Environment**: Happy DOM (browser environment simulation)
- **Database**: PGLite (PostgreSQL for browser environments)
- **Setup File**: `tests/setup.ts`
- **Purpose**: Testing React components, hooks, stores, utilities, and client-side logic
目前只有 `packages/database` 下的测试可以通过配置 `TEST_SERVER_DB=1` 环境变量来使用服务端数据库测试
### Packages Tests
- **配置文件**: [packages/database/vitest.config.mts](mdc:packages/database/vitest.config.mts) 并且设置环境变量 `TEST_SERVER_DB=1`
- **环境**: Node.js
- **数据库**: 真实的 PostgreSQL 数据库
- **并发限制**: 单线程运行 (`singleFork: true`)
- **用途**: 测试数据库模型、服务端逻辑、API 端点等
- **设置文件**: [packages/database/tests/setup-db.ts](mdc:packages/database/tests/setup-db.ts)
Most packages use standard Vitest configuration. However, the `database` package is special:
## 测试运行命令
#### Database Package (Special Case)
** 性能警告**: 项目包含 3000+ 测试用例,完整运行需要约 10 分钟。务必使用文件过滤或测试名称过滤。
The database package supports **dual-environment testing**:
| Environment | Database | Config | Use Case |
|------------------|-----------------|---------------------------------------|-----------------------------------|
| Client (Default) | PGLite | `packages/database/vitest.config.mts` | Fast local development |
| Server | Real PostgreSQL | Set `TEST_SERVER_DB=1` | CI/CD, compatibility verification |
Server environment details:
- **Concurrency**: Single-threaded (`singleFork: true`)
- **Setup File**: `packages/database/tests/setup-db.ts`
- **Requirement**: `DATABASE_TEST_URL` environment variable must be set
### Desktop App Tests
- **Config File**: `apps/desktop/vitest.config.ts`
- **Environment**: Node.js
- **Purpose**: Testing Electron main process controllers, IPC handlers, and desktop-specific logic
## Test Commands
**Performance Warning**: The project contains 3000+ test cases. A full run takes approximately 10 minutes. Always use file filtering or test name filtering.
### Recommended Command Format
### 正确的命令格式
```bash
# Run all client/server tests
bunx vitest run --silent='passed-only' # Client tests
cd packages/database && TEST_SERVER_DB=1 bunx vitest run --silent='passed-only' # Server tests
# 运行所有客户端/服务端测试
bunx vitest run --silent='passed-only' # 客户端测试
cd packages/database && TEST_SERVER_DB=1 bunx vitest run --silent='passed-only' # 服务端测试
# Run specific test file (supports fuzzy matching)
# 运行特定测试文件 (支持模糊匹配)
bunx vitest run --silent='passed-only' user.test.ts
# Run specific test case by name (using -t flag)
# 运行特定测试用例名称 (使用 -t 参数)
bunx vitest run --silent='passed-only' -t "test case name"
# Combine file and test name filtering
# 组合使用文件和测试名称过滤
bunx vitest run --silent='passed-only' filename.test.ts -t "specific test"
# Generate coverage report (using --coverage flag)
# 生成覆盖率报告 (使用 --coverage 参数)
bunx vitest run --silent='passed-only' --coverage
```
### Commands to Avoid
### 避免的命令格式
```bash
# ❌ These commands run all 3000+ test cases, taking ~10 minutes!
# 这些命令会运行所有 3000+ 测试用例,耗时约 10 分钟!
npm test
npm test some-file.test.ts
# ❌ Don't use bare vitest (enters watch mode)
# 不要使用裸 vitest (会进入 watch 模式)
vitest test-file.test.ts
```
## Test Fixing Principles
## 测试修复原则
### Core Principles
### 核心原则
1. **Gather Sufficient Context**
Before fixing tests, ensure you:
- Fully understand the test's intent and implementation
- Strongly recommended: review the current git diff and PR diff
1. **收集足够的上下文**
在修复测试之前,务必做到:
- 完整理解测试的意图和实现
- 强烈建议阅读当前的 git diff PR diff
2. **Prioritize Test Fixes**
If the test itself is incorrect, fix the test first rather than the implementation code.
2. **测试优先修复**
如果是测试本身写错了,应优先修改测试,而不是实现代码。
3. **Focus on a Single Issue**
Only fix the specified test; don't add extra tests along the way.
3. **专注单一问题**
只修复指定的测试,不要顺带添加额外测试。
4. **Don't Act Unilaterally**
When discovering other issues, don't modify them directly—raise and discuss first.
4. **不自作主张**
发现其他问题时,不要直接修改,需先提出并讨论。
### Testing Collaboration Best Practices
### 测试协作最佳实践
Important collaboration principles based on real development experience:
基于实际开发经验总结的重要协作原则:
#### 1. Failure Handling Strategy
#### 1. 失败处理策略
**Core Principle**: Avoid blind retries; quickly identify problems and seek help.
**核心原则**: 避免盲目重试,快速识别问题并寻求帮助。
- **Failure Threshold**: After 1-2 consecutive failed fix attempts, stop immediately
- **Problem Summary**: Analyze failure reasons and document attempted solutions with their failure causes
- **Seek Help**: Approach the team with a clear problem summary and attempt history
- **Avoid the Trap**: Don't fall into the loop of repeatedly trying the same or similar approaches
- **失败阈值**: 当连续尝试修复测试 1-2 次都失败后,应立即停止继续尝试
- **问题总结**: 分析失败原因,整理已尝试的解决方案及其失败原因
- **寻求帮助**: 带着清晰的问题摘要和尝试记录向团队寻求帮助
- **避免陷阱**: 不要陷入"不断尝试相同或类似方法"的循环
```typescript
// ❌ Wrong approach: Keep blindly trying after consecutive failures
// 3rd, 4th attempts still using similar methods to fix the same problem
// 错误做法:连续失败后继续盲目尝试
// 第3次、第4次仍在用相似的方法修复同一个问题
// ✅ Correct approach: Summarize after 1-2 failures
// 正确做法:失败1-2次后总结问题
/*
Problem Summary:
1. Attempted method: Modified mock data structure
2. Failure reason: Still getting type mismatch error
3. Specific error: Expected 'UserData' but received 'UserProfile'
4. Help needed: Unsure about the latest UserData interface definition
问题总结:
1. 尝试过的方法:修改 mock 数据结构
2. 失败原因:仍然提示类型不匹配
3. 具体错误:Expected 'UserData' but received 'UserProfile'
4. 需要帮助:不确定最新的 UserData 接口定义
*/
```
#### 2. Test Case Naming Conventions
#### 2. 测试用例命名规范
**Core Principle**: Tests should focus on "behavior," not "implementation details."
**核心原则**: 测试应该关注"行为",而不是"实现细节"。
- **Describe Business Scenarios**: `describe` and `it` titles should describe specific business scenarios and expected behaviors
- **Avoid Implementation Binding**: Don't mention specific line numbers, coverage goals, or implementation details in test names
- **Maintain Stability**: Test names should remain meaningful after code refactoring
- **描述业务场景**: `describe` `it` 的标题应该描述具体的业务场景和预期行为
- **避免实现绑定**: 不要在测试名称中提及具体的代码行号、覆盖率目标或实现细节
- **保持稳定性**: 测试名称应该在代码重构后仍然有意义
```typescript
// ❌ Poor test naming
// 错误的测试命名
describe('User component coverage', () => {
it('covers line 45-50 in getUserData', () => {
// Test written just to cover lines 45-50
// 为了覆盖第45-50行而写的测试
});
it('tests the else branch', () => {
// Exists only to test a specific branch
// 仅为了测试某个分支而存在
});
});
// ✅ Good test naming
// 正确的测试命名
describe('<UserAvatar />', () => {
it('should render fallback icon when image url is not provided', () => {
// Tests a specific business scenario, naturally covering relevant code branches
// 测试具体的业务场景,自然会覆盖相关代码分支
});
it('should display user initials when avatar image fails to load', () => {
// Describes user behavior and expected outcome
// 描述用户行为和预期结果
});
});
```
**The Right Approach to Improving Coverage**:
**覆盖率提升的正确思路**:
- Naturally improve coverage by designing various business scenarios (happy paths, edge cases, error handling)
- Don't write tests just to hit coverage numbers, and never comment "to cover line xxx" in tests
- 通过设计各种业务场景(正常流程、边缘情况、错误处理)来自然提升覆盖率
- 不要为了达到覆盖率数字而写测试,更不要在测试中注释"为了覆盖 xxx 行"
#### 3. Test Organization Structure
#### 3. 测试组织结构
**Core Principle**: Maintain a clear test hierarchy; avoid redundant top-level test blocks.
**核心原则**: 维护清晰的测试层次结构,避免冗余的顶级测试块。
- **Reuse Existing Structure**: When adding new tests, first look for an appropriate place in existing `describe` blocks
- **Logical Grouping**: Related test cases should be organized within the same `describe` block
- **Avoid Fragmentation**: Don't create a new top-level `describe` block for a single test case
- **复用现有结构**: 添加新测试时,优先在现有的 `describe` 块中寻找合适的位置
- **逻辑分组**: 相关的测试用例应该组织在同一个 `describe` 块内
- **避免碎片化**: 不要为了单个测试用例就创建新的顶级 `describe` 块
```typescript
// ❌ Poor organization: Too many top-level blocks
// 错误的组织方式:创建过多顶级块
describe('<UserProfile />', () => {
it('should render user name', () => {});
});
describe('UserProfile new prop test', () => {
// Unnecessary new block
// 不必要的新块
it('should handle email display', () => {});
});
describe('UserProfile edge cases', () => {
// Unnecessary new block
// 不必要的新块
it('should handle missing avatar', () => {});
});
// ✅ Good organization: Merge related tests
// 正确的组织方式:合并相关测试
describe('<UserProfile />', () => {
it('should render user name', () => {});
@@ -204,78 +178,78 @@ describe('<UserProfile />', () => {

// 只有在有多个相关子场景时才创建子组
it('should show placeholder for missing name', () => {});
it('should hide email section when email is undefined', () => {});
});
});
```
**Organization Decision Flow**:
**组织决策流程**:
1. Is there a logically related existing `describe` block? → If yes, add to it
2. Are there multiple (3+) related test cases? → If yes, consider creating a new sub-`describe`
3. Is it an independent, unrelated feature module? → Only then consider creating a new top-level `describe`
1. 是否存在逻辑相关的现有 `describe` 块? → 如果有,添加到其中
2. 是否有多个(3个以上)相关的测试用例? → 如果有,可以考虑创建新的子 `describe`
3. 是否是独立的、无关联的功能模块? → 如果是,才考虑创建新的顶级 `describe`
### Test Fixing Workflow
### 测试修复流程
1. **Reproduce the Issue**: Locate and run the failing test; confirm it can be reproduced locally
2. **Analyze the Cause**: Read test code, error logs, and Git history of related files
3. **Form a Hypothesis**: Determine if the problem is in test logic, implementation code, or environment configuration
4. **Fix and Verify**: Apply the fix based on your hypothesis; rerun the test to confirm it passes
5. **Expand Verification**: Run all tests in the current file to ensure no new issues were introduced
6. **Write a Summary**: Document the error cause and fix method
1. **复现问题**: 定位并运行失败的测试,确认能在本地复现
2. **分析原因**: 阅读测试代码、错误日志和相关文件的 Git 修改历史
3. **建立假设**: 判断问题出在测试逻辑、实现代码还是环境配置
4. **修复验证**: 根据假设进行修复,重新运行测试确认通过
5. **扩大验证**: 运行当前文件内所有测试,确保没有引入新问题
6. **撰写总结**: 说明错误原因和修复方法
### Post-Fix Summary
### 修复完成后的总结
After completing a test fix, provide a brief explanation including:
测试修复完成后,应该提供简要说明,包括:
1. **Root Cause Analysis**: Explain the fundamental reason for the test failure

## Test Fix Summary
## 测试修复总结
**Root Cause**: The mock data format in the test didn't match the actual API response format, causing assertion failures.
**错误原因**: 测试中的 mock 数据格式与实际 API 返回格式不匹配,导致断言失败。
**Fix**: Updated the mock data structure in the test file to match the latest API response format. Specifically modified the `mockUserData` object structure in `user.test.ts`.
**修复方法**: 更新了测试文件中的 mock 数据结构,使其与最新的 API 响应格式保持一致。具体修改了 `user.test.ts` 中的 `mockUserData` 对象结构。
```
## Test Writing Best Practices
## 测试编写最佳实践
### Mock Data Strategy: Aim for "Low-Cost Authenticity"
### Mock 数据策略:追求"低成本的真实性"
**Core Principle**: Test data should default to authenticity; only simplify when it introduces "high testing costs."
**核心原则**: 测试数据应默认追求真实性,只有在引入"高昂的测试成本"时才进行简化。
#### What Are "High Testing Costs"?
#### 什么是"高昂的测试成本"?
"High cost" refers to introducing external dependencies in tests that make them slow, unstable, or complex:
"高成本"指的是测试中引入了外部依赖,使测试变慢、不稳定或复杂:
- **File I/O Operations**: Reading/writing disk files
- **Network Requests**: HTTP calls, database connections
- **System Calls**: Getting system time, environment variables, etc.
- **文件 I/O 操作**:读写硬盘文件
- **网络请求**:HTTP 调用、数据库连接
- **系统调用**:获取系统时间、环境变量等
#### Recommended Approach: Mock Dependencies, Keep Real Data
#### 推荐做法:Mock 依赖,保留真实数据
```typescript
// ✅ Good approach: Mock I/O operations but use real file content formats
// 好的做法:Mock I/O 操作,但使用真实的文件内容格式
describe('parseContentType', () => {
beforeEach(() => {
// Mock file read operation (avoid real I/O)
// Mock 文件读取操作(避免真实 I/O
vi.spyOn(fs, 'readFileSync').mockImplementation((path) => {
// But return real file content formats
if (path.includes('.pdf')) return '%PDF-1.4\n%âãÏÓ'; // Real PDF header
if (path.includes('.png')) return '\x89PNG\r\n\x1a\n'; // Real PNG header
// 但返回真实的文件内容格式
if (path.includes('.pdf')) return '%PDF-1.4\n%âãÏÓ'; // 真实 PDF 文件头
if (path.includes('.png')) return '\x89PNG\r\n\x1a\n'; // 真实 PNG 文件头
return '';
});

```
#### The Value of Real Identifiers
#### 真实标识符的价值
```typescript
// ✅ Use real identifiers
// ✅ 使用真实标识符
const result = parseModelString('openai', '+gpt-4,+gpt-3.5-turbo');
// ❌ Use placeholders (lower value)
// ❌ 使用占位符(价值较低)
const result = parseModelString('test-provider', '+model1,+model2');
```
### Modern Mocking Techniques: Environment Setup and Mock Methods
### 现代化Mock技巧:环境设置与Mock方法
When testing client-side code, use environment annotations with modern mock methods:
**环境设置 + Mock方法结合使用**
客户端代码测试时,推荐使用环境注释配合现代化Mock方法:
```typescript
/**
* @vitest-environment happy-dom // Provides browser APIs
* @vitest-environment happy-dom // 提供浏览器API
*/
import { beforeEach, vi } from 'vitest';
beforeEach(() => {
// Modern method 1: Use vi.stubGlobal instead of global.xxx = ...
// 现代方法1:使用vi.stubGlobal替代global.xxx = ...

// 现代方法2:使用vi.spyOn保留原功能,只mock特定方法
vi.spyOn(URL, 'createObjectURL').mockReturnValue('blob:mock-url');
vi.spyOn(URL, 'revokeObjectURL').mockImplementation(() => {});
});
```
#### Environment Selection Priority
**环境选择优先级**
1. **@vitest-environment happy-dom** (Recommended) - Lightweight, fast, already installed in the project
2. **@vitest-environment jsdom** - Full-featured, but requires additional jsdom package installation
3. **No environment set** - Node.js environment, requires manually mocking all browser APIs
1. **@vitest-environment happy-dom** (推荐) - 轻量、快速,项目已安装
2. **@vitest-environment jsdom** - 功能完整,但需要额外安装jsdom包
3. **不设置环境** - Node.js环境,需要手动mock所有浏览器API
#### Mock Method Comparison
**Mock方法对比**
```typescript
// ❌ Old method: Directly manipulating global object (type issues)
// ❌ 旧方法:直接操作global对象(类型问题)
global.Image = mockImage;
global.URL = { ...global.URL, createObjectURL: mockFn };
// ✅ Modern method: Type-safe vi API
vi.stubGlobal('Image', mockImage); // Completely replace global object
vi.spyOn(URL, 'createObjectURL'); // Partial mock, preserve other functionality
// ✅ 现代方法:类型安全的vi API
vi.stubGlobal('Image', mockImage); // 完全替换全局对象
vi.spyOn(URL, 'createObjectURL'); // 部分mock,保留其他功能
```
### Test Coverage Principles: Code Branches Over Test Quantity
### 测试覆盖率原则:代码分支优于用例数量
**Core Principle**: Prioritize covering all code branches rather than writing many repetitive test cases.
**核心原则**: 优先覆盖所有代码分支,而非编写大量重复用例
```typescript
// ❌ Over-testing: 29 test cases all validating the same branch
// ❌ 过度测试:29个测试用例都验证相同分支
describe('getImageDimensions', () => {
it('should reject .txt files');
it('should reject .pdf files');
// ... 25 similar tests, all hitting the same validation branch
// ... 25个类似测试,都走相同的验证分支
});
// ✅ Lean testing: 4 core cases covering all branches
// ✅ 精简测试:4个核心用例覆盖所有分支
describe('getImageDimensions', () => {
it('should return dimensions for valid File object'); // Success path - File
it('should return dimensions for valid data URI'); // Success path - String
it('should return undefined for invalid inputs'); // Input validation branch
it('should return undefined when image fails to load'); // Error handling branch
it('should return dimensions for valid File object'); // 成功路径 - File
it('should return dimensions for valid data URI'); // 成功路径 - String
it('should return undefined for invalid inputs'); // 输入验证分支
it('should return undefined when image fails to load'); // 错误处理分支
});
```
#### Branch Coverage Strategy
**分支覆盖策略**
1. **Success Paths** - One test per input type is sufficient
2. **Boundary Conditions** - Consolidate similar scenarios into a single test
3. **Error Handling** - Test representative errors only
4. **Business Logic** - Cover all if/else branches
1. **成功路径** - 每种输入类型1个测试即可
2. **边界条件** - 合并类似场景到单个测试
3. **错误处理** - 测试代表性错误即可
4. **业务逻辑** - 覆盖所有if/else分支
#### Reasonable Test Counts
**合理测试数量**
- Simple utility functions: 2-5 tests
- Complex business logic: 5-10 tests
- Core security features: Add more as needed, but avoid duplicate paths
- 简单工具函数:2-5个测试
- 复杂业务逻辑:5-10个测试
- 核心安全功能:适当增加,但避免重复路径
### Error Handling Tests: Test "Behavior" Not "Text"
### 错误处理测试:测试"行为"而非"文本"
**Core Principle**: Tests should verify that program behavior is predictable when errors occur, not verify error message text that may change.
**核心原则**: 测试应该验证程序在错误发生时的行为是可预测的,而不是验证易变的错误信息文本。
#### Recommended Error Testing Approach
#### 推荐的错误测试方式
```typescript
// ✅ Test error types and properties
// ✅ 测试错误类型和属性
expect(() => validateUser({})).toThrow(ValidationError);
expect(() => processPayment({})).toThrow(
expect.objectContaining({
@@ -399,136 +375,136 @@ expect(() => processPayment({})).toThrow(

// ❌ 避免测试具体错误文本

```
### Troubleshooting: Beware of Module Pollution
### 疑难解答:警惕模块污染
**Warning Signs**: When your tests exhibit these "mysterious" behaviors, suspect module pollution first:
**识别信号**: 当你的测试出现以下"灵异"现象时,优先怀疑模块污染:
- A test passes when run alone but fails when run with other tests
- Test execution order affects results
- Mock setup appears correct but actually uses an old mock version
- 单独运行某个测试通过,但和其他测试一起运行就失败
- 测试的执行顺序影响结果
- Mock 设置看起来正确,但实际使用的是旧的 Mock 版本
#### Typical Scenario: Dynamic Mocking of the Same Module
#### 典型场景:动态 Mock 同一模块
```typescript
// ❌ Problem: Dynamic mocking of the same module
// ❌ 问题:动态Mock同一模块
it('dev mode', async () => {
vi.doMock('./config', () => ({ isDev: true }));
const { getSettings } = await import('./service'); // May use cache
const { getSettings } = await import('./service'); // 可能使用缓存
});
// ✅ Solution: Clear module cache
// ✅ 解决:清除模块缓存
beforeEach(() => {
vi.resetModules(); // Ensure each test has a clean environment
vi.resetModules(); // 确保每个测试都是干净环境
});
```
**Remember**: `vi.resetModules()` is the ultimate weapon for resolving "mysterious" test failures.
**记住**: `vi.resetModules()` 是解决测试"灵异"失败的终极武器。
## Test File Organization
## 测试文件组织
### File Naming Convention
### 文件命名约定
`*.test.ts`, `*.test.tsx` (any location)
`*.test.ts`, `*.test.tsx` (任意位置)
### Test File Organization Style
### 测试文件组织风格
The project uses a **co-located test files** organization style:
项目采用 **测试文件与源文件同目录** 的组织风格:
- Test files are placed in the same directory as the corresponding source files
- Naming format: `originalFileName.test.ts` or `originalFileName.test.tsx`
- 测试文件放在对应源文件的同一目录下
- 命名格式:`原文件名.test.ts` 或 `原文件名.test.tsx`
Example:
例如:
```plaintext
src/components/Button/
├── index.tsx # Source file
└── index.test.tsx # Test file
├── index.tsx # 源文件
└── index.test.tsx # 测试文件
```
- In some cases, tests are consolidated in a `__tests__` folder, e.g., `packages/database/src/models/__tests__`
- Test helper files are placed in a fixtures folder
- 也有少数情况会统一放到 `__tests__` 文件夹, 例如 `packages/database/src/models/__tests__`
- 测试使用的辅助文件放到 fixtures 文件夹
## Test Debugging Tips
## 测试调试技巧
### Test Debugging Steps
### 测试调试步骤
1. **Determine Test Environment**: Select the correct config file based on file path
2. **Isolate the Problem**: Use the `-t` flag to run only the failing test case
3. **Analyze the Error**: Carefully read error messages, stack traces, and recent file modification history
4. **Add Debugging**: Add `console.log` statements in tests to understand execution flow
1. **确定测试环境**: 根据文件路径选择正确的配置文件
2. **隔离问题**: 使用 `-t` 参数只运行失败的测试用例
3. **分析错误**: 仔细阅读错误信息、堆栈跟踪和最近的文件修改记录
4. **添加调试**: 在测试中添加 `console.log` 了解执行流程
### TypeScript Type Handling
### TypeScript 类型处理
In tests, you can relax TypeScript type checking to improve writing efficiency and readability:
在测试中,为了提高编写效率和可读性,可以适当放宽 TypeScript 类型检测:
#### Recommended Type Relaxation Strategies
#### 推荐的类型放宽策略
```typescript
// Use non-null assertion to access properties you're certain exist in tests
// 使用非空断言访问测试中确定存在的属性
const result = await someFunction();
expect(result!.data).toBeDefined();
expect(result!.status).toBe('success');
// Use any type to simplify complex mock setups
// 使用 any 类型简化复杂的 Mock 设置
const mockStream = new ReadableStream() as any;
mockStream.toReadableStream = () => mockStream;
// Access private members
await instance['getFromCache']('key'); // Bracket notation recommended
await (instance as any).getFromCache('key'); // Avoid as any
// 访问私有成员
await instance['getFromCache']('key'); // 推荐中括号
await (instance as any).getFromCache('key'); // 避免as any
```
#### Applicable Scenarios
#### 适用场景
- **Mock Objects**: Use `as any` for test mock data to avoid complex type definitions
- **Third-Party Libraries**: Use `any` appropriately when handling complex third-party library types
- **Test Assertions**: Use `!` non-null assertion in test scenarios where you're certain the object exists
- **Private Member Access**: Prefer bracket notation `instance['privateMethod']()` over `(instance as any).privateMethod()`
- **Temporary Debugging**: When quickly writing tests, use `any` first to ensure functionality, then optionally optimize types later
- **Mock 对象**: 对于测试用的 Mock 数据,使用 `as any` 避免复杂的类型定义
- **第三方库**: 处理复杂的第三方库类型时,适当使用 `any` 提高效率
- **测试断言**: 在确定对象存在的测试场景中,使用 `!` 非空断言
- **私有成员访问**: 优先使用中括号 `instance['privateMethod']()` 而不是 `(instance as any).privateMethod()`
- **临时调试**: 快速编写测试时,先用 `any` 保证功能,后续可选择性地优化类型
#### Important Notes
#### 注意事项
- **Use Moderately**: Don't over-rely on `any`; core business logic types should remain strict
- **Private Member Access Priority**: Bracket notation > `as any` casting for better type safety
- **Documentation**: Add comments explaining the reason for complex `any` usage scenarios
- **Test Coverage**: Ensure tests still effectively verify correctness even when using `any`
- **适度使用**: 不要过度依赖 `any`,核心业务逻辑的类型仍应保持严格
- **私有成员访问优先级**: 中括号访问 > `as any` 转换,保持更好的类型安全性
- **文档说明**: 对于使用 `any` 的复杂场景,添加注释说明原因
- **测试覆盖**: 确保即使使用了 `any`,测试仍能有效验证功能正确性
### Checking Recent Modifications
### 检查最近修改记录
**Core Principle**: When tests suddenly fail, first check recent code changes.
**核心原则**:测试突然失败时,优先检查最近的代码修改。
#### Quick Check Methods
#### 快速检查方法
```bash
git status # View current modification status
git diff HEAD -- '*.test.*' # Check test file changes
git diff main...HEAD # Compare with main branch
gh pr diff # View all changes in the PR
git status # 查看当前修改状态
git diff HEAD -- '*.test.*' # 检查测试文件改动
git diff main...HEAD # 对比主分支差异
gh pr diff # 查看PR中的所有改动
```
#### Common Causes and Solutions
#### 常见原因与解决
- **Latest commit introduced a bug** → Check and fix the implementation code
- **Branch code is outdated** → `git rebase main` to sync with main branch
- **最新提交引入bug** → 检查并修复实现代码
- **分支代码滞后** → `git rebase main` 同步主分支

## Key Takeaways
## 核心要点
- **Command Format**: Use `bunx vitest run --silent='passed-only'` with file filtering
- **Fix Principles**: Seek help after 1-2 failures; focus test naming on behavior, not implementation details
- **Debug Workflow**: Reproduce → Analyze → Hypothesize → Fix → Verify → Summarize
- **File Organization**: Prefer adding tests to existing `describe` blocks; avoid creating redundant top-level blocks
- **Data Strategy**: Default to authenticity; only simplify for high-cost scenarios (I/O, network, etc.)
- **Error Testing**: Test error types and behavior; avoid depending on specific error message text
- **Module Pollution**: When tests fail "mysteriously," suspect module pollution first; use `vi.resetModules()` to resolve
- **Security Requirements**: Model tests must include permission checks and pass in both environments
- **命令格式**: 使用 `bunx vitest run --silent='passed-only'` 并指定文件过滤
- **修复原则**: 失败1-2次后寻求帮助,测试命名关注行为而非实现细节
- **调试流程**: 复现 → 分析 → 假设 → 修复 → 验证 → 总结
- **文件组织**: 优先在现有 `describe` 块中添加测试,避免创建冗余顶级块
- **数据策略**: 默认追求真实性,只有高成本(I/O、网络等)时才简化
- **错误测试**: 测试错误类型和行为,避免依赖具体的错误信息文本
- **模块污染**: 测试"灵异"失败时,优先怀疑模块污染,使用 `vi.resetModules()` 解决
- **安全要求**: Model 测试必须包含权限检查,并在双环境下验证通过

# Vercel React Best Practices
Comprehensive performance optimization guide for React and Next.js applications, maintained by Vercel. Contains 45 rules across 8 categories, prioritized by impact to guide automated refactoring and code generation.
## When to Apply
Reference these guidelines when:
- Writing new React components or Next.js pages
- Implementing data fetching (client or server-side)
- Reviewing code for performance issues
- Refactoring existing React/Next.js code
- Optimizing bundle size or load times
## Rule Categories by Priority
| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | Eliminating Waterfalls | CRITICAL | `async-` |
| 2 | Bundle Size Optimization | CRITICAL | `bundle-` |
| 3 | Server-Side Performance | HIGH | `server-` |
| 4 | Client-Side Data Fetching | MEDIUM-HIGH | `client-` |
| 5 | Re-render Optimization | MEDIUM | `rerender-` |
| 6 | Rendering Performance | MEDIUM | `rendering-` |
| 7 | JavaScript Performance | LOW-MEDIUM | `js-` |
| 8 | Advanced Patterns | LOW | `advanced-` |
## Quick Reference
### 1. Eliminating Waterfalls (CRITICAL)
- `async-defer-await` - Move await into branches where actually used
- `async-parallel` - Use Promise.all() for independent operations
- `async-dependencies` - Use better-all for partial dependencies
- `async-api-routes` - Start promises early, await late in API routes
- `async-suspense-boundaries` - Use Suspense to stream content
### 2. Bundle Size Optimization (CRITICAL)
- `bundle-barrel-imports` - Import directly, avoid barrel files
- `bundle-dynamic-imports` - Use next/dynamic for heavy components
- `bundle-defer-third-party` - Load analytics/logging after hydration
- `bundle-conditional` - Load modules only when feature is activated
- `bundle-preload` - Preload on hover/focus for perceived speed
### 3. Server-Side Performance (HIGH)
- `server-cache-react` - Use React.cache() for per-request deduplication
- `server-cache-lru` - Use LRU cache for cross-request caching
- `server-serialization` - Minimize data passed to client components
- `server-parallel-fetching` - Restructure components to parallelize fetches
- `server-after-nonblocking` - Use after() for non-blocking operations
### 4. Client-Side Data Fetching (MEDIUM-HIGH)
- `client-swr-dedup` - Use SWR for automatic request deduplication
- `client-event-listeners` - Deduplicate global event listeners
### 5. Re-render Optimization (MEDIUM)
- `rerender-defer-reads` - Don't subscribe to state only used in callbacks
- `rerender-memo` - Extract expensive work into memoized components
- `rerender-dependencies` - Use primitive dependencies in effects
- `rerender-derived-state` - Subscribe to derived booleans, not raw values
- `rerender-functional-setstate` - Use functional setState for stable callbacks
- `rerender-lazy-state-init` - Pass function to useState for expensive values
- `rerender-transitions` - Use startTransition for non-urgent updates
### 6. Rendering Performance (MEDIUM)
- `rendering-animate-svg-wrapper` - Animate div wrapper, not SVG element
- `rendering-content-visibility` - Use content-visibility for long lists

## Store Event Handlers in Refs
Store callbacks in refs when used in effects that shouldn't re-subscribe on callback changes.
**Incorrect (re-subscribes on every render):**
```tsx
function useWindowEvent(event: string, handler: (e) => void) {
useEffect(() => {
window.addEventListener(event, handler)
return () => window.removeEventListener(event, handler)
}, [event, handler])
}
```
**Correct (stable subscription):**
```tsx
function useWindowEvent(event: string, handler: (e) => void) {
const handlerRef = useRef(handler)
useEffect(() => {
handlerRef.current = handler
}, [handler])
useEffect(() => {
const listener = (e) => handlerRef.current(e)
window.addEventListener(event, listener)
return () => window.removeEventListener(event, listener)
}, [event])
}
```
**Alternative: use `useEffectEvent` if you're on latest React:**
```tsx
import { useEffectEvent } from 'react'
function useWindowEvent(event: string, handler: (e) => void) {
const onEvent = useEffectEvent(handler)
useEffect(() => {
window.addEventListener(event, onEvent)
return () => window.removeEventListener(event, onEvent)
}, [event])
}
```
`useEffectEvent` provides a cleaner API for the same pattern: it creates a stable function reference that always calls the latest version of the handler.

## useLatest for Stable Callback Refs
Access latest values in callbacks without adding them to dependency arrays. Prevents effect re-runs while avoiding stale closures.

useLayoutEffect(() => {
ref.current = value
}, [value])

}, [query, onSearch])
}

const [query, setQuery] = useState('')
const onSearchRef = useLatest(onSearch)
useEffect(() => {

## Prevent Waterfall Chains in API Routes
In API routes and Server Actions, start independent operations immediately, even if you don't await them yet.
**Incorrect (config waits for auth, data waits for both):**
```typescript
export async function GET(request: Request) {
const session = await auth()
const config = await fetchConfig()
const data = await fetchData(session.user.id)

}
```

export async function GET(request: Request) {
const sessionPromise = auth()
const configPromise = fetchConfig()
const session = await sessionPromise
const [config, data] = await Promise.all([
configPromise,
fetchData(session.user.id)
])
return Response.json({ data, config })
}

## Defer Await Until Needed
Move `await` operations into the branches where they're actually used to avoid blocking code paths that don't need them.
**Incorrect (blocks both branches):**
```typescript
async function handleRequest(userId: string, skipProcessing: boolean) {
const userData = await fetchUserData(userId)
if (skipProcessing) {
// Returns immediately but still waited for userData
return { skipped: true }
}
// Only this branch uses userData
return processUserData(userData)
}
```
**Correct (only blocks when needed):**
```typescript
async function handleRequest(userId: string, skipProcessing: boolean) {
if (skipProcessing) {
// Returns immediately without waiting
return { skipped: true }
}
// Fetch only when needed
const userData = await fetchUserData(userId)
return processUserData(userData)
}
```
**Another example (early return optimization):**
```typescript
// Incorrect: always fetches permissions
async function updateResource(resourceId: string, userId: string) {
const permissions = await fetchPermissions(userId)
const resource = await getResource(resourceId)
if (!resource) {
return { error: 'Not found' }
}
if (!permissions.canEdit) {
return { error: 'Forbidden' }
}
return await updateResourceData(resource, permissions)
}
// Correct: fetches only when needed
async function updateResource(resourceId: string, userId: string) {
const resource = await getResource(resourceId)
if (!resource) {
return { error: 'Not found' }
}
const permissions = await fetchPermissions(userId)
if (!permissions.canEdit) {
return { error: 'Forbidden' }
}
return await updateResourceData(resource, permissions)
}
```
This optimization is especially valuable when the skipped branch is frequently taken, or when the deferred operation is expensive.

title: Strategic Suspense Boundaries
impact: HIGH
impactDescription: faster initial paint
tags: async, suspense, streaming, layout-shift
---
## Strategic Suspense Boundaries
Instead of awaiting data in async components before returning JSX, use Suspense boundaries to show the wrapper UI faster while data loads.
**Incorrect (wrapper blocked by data fetching):**
```tsx
async function Page() {
const data = await fetchData() // Blocks entire page
return (
<div>
<div>Sidebar</div>
<div>Header</div>
<div>
<DataDisplay data={data} />
</div>
<div>Footer</div>
</div>
)
}
```
The entire layout waits for data even though only the middle section needs it.
**Correct (wrapper shows immediately, data streams in):**
```tsx
function Page() {
return (
<div>
<div>Sidebar</div>
<div>Header</div>
<div>
<Suspense fallback={<Skeleton />}>
<DataDisplay />
</Suspense>
</div>
<div>Footer</div>
</div>
)
}
async function DataDisplay() {
const data = await fetchData() // Only blocks this component
return <div>{data.content}</div>
}
```
Sidebar, Header, and Footer render immediately. Only DataDisplay waits for data.
**Alternative (share promise across components):**
```tsx
function Page() {
// Start fetch immediately, but don't await
const dataPromise = fetchData()
return (
<div>
<div>Sidebar</div>
<div>Header</div>
<Suspense fallback={<Skeleton />}>
<DataDisplay dataPromise={dataPromise} />
<DataSummary dataPromise={dataPromise} />
</Suspense>
<div>Footer</div>
</div>
)
}
function DataDisplay({ dataPromise }: { dataPromise: Promise<Data> }) {
const data = use(dataPromise) // Unwraps the promise
return <div>{data.content}</div>
}
function DataSummary({ dataPromise }: { dataPromise: Promise<Data> }) {
const data = use(dataPromise) // Reuses the same promise
return <div>{data.summary}</div>
}
```
Both components share the same promise, so only one fetch occurs. Layout renders immediately while both components wait together.
**When NOT to use this pattern:**
- Critical data needed for layout decisions (affects positioning)
- SEO-critical content above the fold
- Small, fast queries where suspense overhead isn't worth it
- When you want to avoid layout shift (loading → content jump)
**Trade-off:** Faster initial paint vs potential layout shift. Choose based on your UX priorities.

title: Avoid Barrel File Imports
impact: CRITICAL
impactDescription: 200-800ms import cost, slow builds
tags: bundle, imports, tree-shaking, barrel-files, performance
---
## Avoid Barrel File Imports
Import directly from source files instead of barrel files to avoid loading thousands of unused modules. **Barrel files** are entry points that re-export multiple modules (e.g., `index.js` that does `export * from './module'`).
Popular icon and component libraries can have **up to 10,000 re-exports** in their entry file. For many React packages, **it takes 200-800ms just to import them**, affecting both development speed and production cold starts.
**Why tree-shaking doesn't help:** When a library is marked as external (not bundled), the bundler can't optimize it. If you bundle it to enable tree-shaking, builds become substantially slower analyzing the entire module graph.
**Incorrect (imports entire library):**
```tsx
import { Check, X, Menu } from 'lucide-react'
// Loads 1,583 modules, takes ~2.8s extra in dev
// Runtime cost: 200-800ms on every cold start
import { Button, TextField } from '@mui/material'
// Loads 2,225 modules, takes ~4.2s extra in dev
```
**Correct (imports only what you need):**
```tsx
import Check from 'lucide-react/dist/esm/icons/check'
import X from 'lucide-react/dist/esm/icons/x'
import Menu from 'lucide-react/dist/esm/icons/menu'
// Loads only 3 modules (~2KB vs ~1MB)
import Button from '@mui/material/Button'
import TextField from '@mui/material/TextField'
// Loads only what you use
```
**Alternative (Next.js 13.5+):**
```js
// next.config.js - use optimizePackageImports
module.exports = {
experimental: {
optimizePackageImports: ['lucide-react', '@mui/material']
}
}
// Then you can keep the ergonomic barrel imports:
import { Check, X, Menu } from 'lucide-react'
// Automatically transformed to direct imports at build time
```
Direct imports provide 15-70% faster dev boot, 28% faster builds, 40% faster cold starts, and significantly faster HMR.
Libraries commonly affected: `lucide-react`, `@mui/material`, `@mui/icons-material`, `@tabler/icons-react`, `react-icons`, `@headlessui/react`, `@radix-ui/react-*`, `lodash`, `ramda`, `date-fns`, `rxjs`, `react-use`.

## Batch DOM CSS Changes
Avoid interleaving style writes with layout reads. When you read a layout property (like `offsetWidth`, `getBoundingClientRect()`, or `getComputedStyle()`) between style changes, the browser is forced to trigger a synchronous reflow.
**Incorrect (interleaved reads and writes force reflows):**
```typescript
function updateElementStyles(element: HTMLElement) {
element.style.width = '100px'
const width = element.offsetWidth // Forces reflow
element.style.height = '200px'
const height = element.offsetHeight // Forces another reflow
}
```
**Correct (batch writes, then read once):**
```typescript
function updateElementStyles(element: HTMLElement) {
// Batch all writes together
element.style.width = '100px'
element.style.height = '200px'
element.style.backgroundColor = 'blue'
element.style.border = '1px solid black'
// Read after all writes are done (single reflow)
const { width, height } = element.getBoundingClientRect()
}
```
**Better: use CSS classes**
```css
.highlighted-box {
width: 100px;
height: 200px;
background-color: blue;
border: 1px solid black;
}
```
```typescript
function updateElementStyles(element: HTMLElement) {
element.classList.add('highlighted-box')

```typescript
// Module-level cache
const slugifyCache = new Map<string, string>()
function cachedSlugify(text: string): string {
if (slugifyCache.has(text)) {
return slugifyCache.get(text)!
}
const result = slugify(text)
slugifyCache.set(text, result)
return result
}
function ProjectList({ projects }: { projects: Project[] }) {
return (
<div>
{projects.map(project => {
// Computed only once per unique project name
const slug = cachedSlugify(project.name)
return <ProjectCard key={project.id} slug={slug} />
})}
</div>
)
}
```
**Simpler pattern for single-value functions:**
```typescript
let isLoggedInCache: boolean | null = null
function isLoggedIn(): boolean {
if (isLoggedInCache !== null) {
return isLoggedInCache
}
isLoggedInCache = document.cookie.includes('auth=')
return isLoggedInCache
}
// Clear cache when auth changes
function onAuthChange() {
isLoggedInCache = null
}
```
Use a Map (not a hook) so it works everywhere: utilities, event handlers, not just React components.

## Cache Property Access in Loops
Cache object property lookups in hot paths.
**Incorrect (3 lookups × N iterations):**
```typescript
for (let i = 0; i < arr.length; i++) {
process(obj.config.settings.value)
}
```
**Correct (1 lookup total):**
```typescript
const value = obj.config.settings.value
const len = arr.length
for (let i = 0; i < len; i++) {
process(value)
}
```

title: Cache Storage API Calls
impact: LOW-MEDIUM
impactDescription: reduces expensive I/O
tags: javascript, localStorage, storage, caching, performance

## Cache Storage API Calls
`localStorage`, `sessionStorage`, and `document.cookie` are synchronous and expensive. Cache reads in memory.
**Incorrect (reads storage on every call):**
```typescript
function getTheme() {
return localStorage.getItem('theme') ?? 'light'
}
// Called 10 times = 10 storage reads
```
**Correct (Map cache):**
```typescript
const storageCache = new Map<string, string | null>()
function getLocalStorage(key: string) {
if (!storageCache.has(key)) {
storageCache.set(key, localStorage.getItem(key))
}
return storageCache.get(key)
}
function setLocalStorage(key: string, value: string) {
localStorage.setItem(key, value)
storageCache.set(key, value) // keep cache in sync
}
```
Use a Map (not a hook) so it works everywhere: utilities, event handlers, not just React components.
**Cookie caching:**
```typescript
let cookieCache: Record<string, string> | null = null
function getCookie(name: string) {
if (!cookieCache) {
cookieCache = Object.fromEntries(
document.cookie.split('; ').map(c => c.split('='))
)
}
return cookieCache[name]
}
```
**Important (invalidate on external changes):**
If storage can change externally (another tab, server-set cookies), invalidate cache:
```typescript
window.addEventListener('storage', (e) => {
if (e.key) storageCache.delete(e.key)
})
document.addEventListener('visibilitychange', () => {
if (document.visibilityState === 'visible') {
storageCache.clear()
}
})
```

title: Combine Multiple Array Iterations
impact: LOW-MEDIUM
impactDescription: reduces iterations

## Combine Multiple Array Iterations
Multiple `.filter()` or `.map()` calls iterate the array multiple times. Combine into one loop.
**Incorrect (3 iterations):**
```typescript
const admins = users.filter(u => u.isAdmin)
const testers = users.filter(u => u.isTester)
const inactive = users.filter(u => !u.isActive)
```
**Correct (1 iteration):**
```typescript
const admins: User[] = []
const testers: User[] = []
const inactive: User[] = []
for (const user of users) {
if (user.isAdmin) admins.push(user)
if (user.isTester) testers.push(user)
if (!user.isActive) inactive.push(user)
}

title: Early Return from Functions

---
## Early Return from Functions
Return early when result is determined to skip unnecessary processing.
**Incorrect (processes all items even after finding answer):**
```typescript
function validateUsers(users: User[]) {
let hasError = false
let errorMessage = ''
for (const user of users) {
if (!user.email) {
hasError = true
errorMessage = 'Email required'
}
if (!user.name) {
hasError = true
errorMessage = 'Name required'
}
// Continues checking all users even after error found
}
return hasError ? { valid: false, error: errorMessage } : { valid: true }
}
```
**Correct (returns immediately on first error):**
```typescript
function validateUsers(users: User[]) {
for (const user of users) {
if (!user.email) {
return { valid: false, error: 'Email required' }
}
if (!user.name) {
return { valid: false, error: 'Name required' }
}
}
return { valid: true }
}
```
