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
src/components— project-specific reusable components@lobehub/ui/base-ui— headless primitives. If the component lives here, use it. Do NOT import the same-named root export.@lobehub/ui— higher-level / antd-wrapping components (only when no base-ui equivalent)- antd — only when neither base-ui nor
@lobehub/uiroot provides it - 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 |
|---|---|
Alert (+ AlertProps) |
import { Alert, type AlertProps } from '@lobehub/ui/base-ui'; |
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'; |
Drawer |
import { Drawer } 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 forModal,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 |
| Layout | Center, DraggablePanel, Flexbox, Grid, Header, MaskShadow |
| Navigation | Burger, Menu, SideNav, Tabs |
State
Keep transient state in its smallest useful owner. Extract a custom hook when state transitions and handlers obscure rendering or form a reusable unit; do not extract solely because a component has a particular number of hooks.
Split a component only to establish a real state, reuse, render-update, or mountable-capability boundary. Do not split solely to make files smaller; when a file reaches the 1200-line limit in source-layout, find one of these boundaries rather than cutting at a line count. Decomposing a heavy domain feature into host-assembled atoms is owned by compose-atoms.
Render Performance and Memoization
Treat memo, useMemo, and useCallback as opt-in optimizations, not default component wrappers. Before adding one, identify the actual rerender boundary and prefer structural fixes:
- Split at the update boundary.
- Move transient state to its smallest owner.
- Use narrow Zustand selectors and avoid broad subscriptions.
Do not memoize prop-free or trivially rendered components, or a component that normally receives new objects, arrays, functions, or JSX children. Do not use memoization to compensate for state held too high in the tree.
Use memoization only when the subtree is demonstrably expensive or frequently repeated, its relevant inputs are stable during normal parent renders, and profiling or a concrete render-path analysis identifies the avoided work. State that reason in the implementation summary or PR.
Layout
Use Flexbox and Center from @lobehub/ui. See references/layout-kit.md for full props and examples.
- Use
gapinstead ofmarginfor spacing between flex children - Use
flex={1}to fill available space - Nest Flexbox for complex layouts; set
overflow: 'auto'for scrollable regions
