React Component Writing Guide

Styling

Scenario	Approach
Most cases	createStaticStyles + cssVar.* (zero-runtime, module-level)
Simple one-off	Inline style attribute
Truly dynamic (JS color fns like readableColor/chroma)	createStyles + token — last resort

Component Priority

1. src/components — project-specific reusable components
2. @lobehub/ui/base-ui — headless primitives. If the component lives here, use it. Do NOT import the same-named root export.
3. @lobehub/ui — higher-level / antd-wrapping components (only when no base-ui equivalent)
4. antd — only when neither base-ui nor @lobehub/ui root provides it
5. Custom implementation — true last resort

If unsure about available components, search existing code or check node_modules/@lobehub/ui/es/index.mjs and node_modules/@lobehub/ui/es/base-ui/.

@lobehub/ui/base-ui — always prefer for these

Component	Import
Select (+ SelectProps, SelectOption)	import { Select } from '@lobehub/ui/base-ui';
Modal (imperative API)	import { createModal, confirmModal, useModalContext, type ModalInstance } from '@lobehub/ui/base-ui';
DropdownMenu	import { DropdownMenu } from '@lobehub/ui/base-ui';
ContextMenu	import { ContextMenu } from '@lobehub/ui/base-ui';
Popover	import { Popover } from '@lobehub/ui/base-ui';
ScrollArea	import { ScrollArea } from '@lobehub/ui/base-ui';
Switch	import { Switch } from '@lobehub/ui/base-ui';
Toast	import { Toast } from '@lobehub/ui/base-ui';
FloatingSheet	import { FloatingSheet } from '@lobehub/ui/base-ui';

For Modal specifically, see the dedicated modal skill — use the imperative createModal({ content: … }) pattern over the legacy <Modal open … /> declarative pattern. base-ui has its own ModalHost already mounted in SPAGlobalProvider.

Common slip: import { Select } from '@lobehub/ui' looks fine but it's the antd-backed Select. Use base-ui Select. Same for Modal, DropdownMenu, etc.

@lobehub/ui root — use when base-ui has no equivalent

Category	Components
General	ActionIcon, ActionIconGroup, Block, Button, Icon
Data Display	Avatar, Collapse, Empty, Highlighter, Markdown, Tag, Tooltip
Data Entry	CodeEditor, CopyButton, EditableText, Form, Input, InputPassword, SearchBar, TextArea
Feedback	Alert, Drawer
Layout	Center, DraggablePanel, Flexbox, Grid, Header, MaskShadow
Navigation	Burger, Menu, SideNav, Tabs

State

When a feature component manages more than 3 pieces of state (useState/useReducer/derived state), extract the logic into a custom hook (e.g. useXxx). Keep the component focused on rendering — the hook holds state and handlers, so logic can be unit-tested without rendering the component.

Layout

Use Flexbox and Center from @lobehub/ui. See references/layout-kit.md for full props and examples.

• Use gap instead of margin for spacing between flex children
• Use flex={1} to fill available space
• Nest Flexbox for complex layouts; set overflow: 'auto' for scrollable regions

Navigation

For SPA pages, use react-router-dom, NOT next/link.

// ❌ Wrong
import Link from 'next/link';

// ✅ Correct
import { Link, useNavigate } from 'react-router-dom';

Access navigate from stores: useGlobalStore.getState().navigate?.('/settings');

Desktop File Sync Rule

Files with a .desktop.ts(x) variant must be edited in sync. Drift causes blank pages in Electron.

Base file (web)	Desktop file (Electron)
desktopRouter.config.tsx	desktopRouter.config.desktop.tsx
componentMap.ts	componentMap.desktop.ts

After editing any .ts/.tsx: glob for <filename>.desktop.{ts,tsx} in the same directory. If found, apply the equivalent sync-import change.

Routing Architecture

Route Type	Use Case	Implementation
Next.js App Router	Auth pages	src/app/[variants]/(auth)/
React Router DOM	Main SPA	desktopRouter.config.tsx + .desktop.tsx (pair)

Router utilities:

import { dynamicElement, redirectElement, ErrorBoundary } from '@/utils/router';
element: dynamicElement(() => import('./chat'), 'Desktop > Chat');
element: redirectElement('/settings/profile');
errorElement: <ErrorBoundary />;

Common Mistakes

Mistake	Fix
Using next/link in SPA	Use react-router-dom Link
Using antd directly	Use @lobehub/ui/base-ui first, then @lobehub/ui
import { Select } from '@lobehub/ui'	import { Select } from '@lobehub/ui/base-ui'
import { Modal } from '@lobehub/ui' + <Modal open> declarative	createModal / confirmModal from @lobehub/ui/base-ui (see modal skill)
import { DropdownMenu/Popover/Switch } from '@lobehub/ui'	Import same name from @lobehub/ui/base-ui instead
createStyles for static styles	Use createStaticStyles + cssVar
Editing only desktopRouter.config.tsx	Must edit both .tsx and .desktop.tsx
Using margin for flex spacing	Use gap prop on Flexbox
Accessing zustand store without selector	Use selectors to access store data (see zustand skill)
Text or icon-text actions built with Flexbox/Text + onClick	Use Button type={'text'} size={'small'} with icon when needed
