React Component Writing Guide

• Use antd-style for complex styles; for simple cases, use inline style attribute

- **Prefer createStaticStyles with cssVar.*** (zero-runtime) — module-level, no hook call required - Only fall back to createStyles + token when styles genuinely need runtime computation (dynamic props, JS color fns like readableColor/chroma) - See .cursor/docs/createStaticStyles_migration_guide.md for full pattern

• Use Flexbox and Center from @lobehub/ui for layouts (see references/layout-kit.md)
• Component priority: src/components > @lobehub/ui/base-ui > @lobehub/ui > custom implementation

- Always prefer @lobehub/ui/base-ui primitives (Select, Modal, DropdownMenu, Popover, Switch, ScrollArea…) over antd equivalents - Fall back to @lobehub/ui higher-level components when base-ui has no match - Only implement a custom component as a last resort — never reach for antd directly

• Use selectors to access zustand store data

@lobehub/ui Components

If unsure about component usage, search existing code in this project. Most components extend antd with additional props.

Reference: node_modules/@lobehub/ui/es/index.mjs for all available components.

Common Components:

• General: ActionIcon, ActionIconGroup, Block, Button, Icon
• Data Display: Avatar, Collapse, Empty, Highlighter, Markdown, Tag, Tooltip
• Data Entry: CodeEditor, CopyButton, EditableText, Form, FormModal, Input, SearchBar, Select
• Feedback: Alert, Drawer, Modal
• Layout: Center, DraggablePanel, Flexbox, Grid, Header, MaskShadow
• Navigation: Burger, Dropdown, Menu, SideNav, Tabs

Routing Architecture

Hybrid routing: Next.js App Router (static pages) + React Router DOM (main SPA).

Key Files

• Entry: src/spa/entry.web.tsx (web), src/spa/entry.mobile.tsx, src/spa/entry.desktop.tsx
• Desktop router (pair — always edit both when changing routes): src/spa/router/desktopRouter.config.tsx (dynamic imports) and src/spa/router/desktopRouter.config.desktop.tsx (sync imports). Drift can cause unregistered routes / blank screen.
• Mobile router: src/spa/router/mobileRouter.config.tsx
• Router utilities: src/utils/router.tsx

.desktop.{ts,tsx} File Sync Rule

CRITICAL: Some files have a .desktop.ts(x) variant that Electron uses instead of the base file. When editing a base file, always check if a .desktop counterpart exists and update it in sync. Drift causes blank pages or missing features in Electron.

Known pairs that must stay in sync:

How to check: After editing any .ts / .tsx file, run Glob for <filename>.desktop.{ts,tsx} in the same directory. If a match exists, update it with the equivalent sync-import change.

Router Utilities

import { dynamicElement, redirectElement, ErrorBoundary } from '@/utils/router';

element: dynamicElement(() => import('./chat'), 'Desktop > Chat');
element: redirectElement('/settings/profile');
errorElement: <ErrorBoundary />;

Navigation

Important: For SPA pages, use Link from react-router-dom, NOT next/link.

// ❌ Wrong
import Link from 'next/link';
<Link href="/">Home</Link>;

// ✅ Correct
import { Link } from 'react-router-dom';
<Link to="/">Home</Link>;

// In components
import { useNavigate } from 'react-router-dom';
const navigate = useNavigate();
navigate('/chat');

// From stores
const navigate = useGlobalStore.getState().navigate;
navigate?.('/settings');
