# CLAUDE.md — duoqi-admin

> 多奇管理后台，基于 Vite + React + TypeScript + shadcn/ui + Tailwind CSS
> 调用 duoqi-api 的 admin 端点，CSR 纯前端应用

## Current Status

**Phase 1a complete.** Project scaffold built. Phase 1b (Question CRUD) is next.

Development follows the phased roadmap in [dev-spec.md](./dev-spec.md) §九.

## Quick Start

```bash
bun install
bun run dev          # Vite dev server, default port 5173
bun run build        # Production build → dist/
```

## Environment

`.env` is already configured. To change the API URL, edit `.env`:

```env
VITE_API_BASE_URL=http://localhost:3000   # duoqi-api address
```

```

## Key Patterns

- **Routing**: React Router v7 library mode (`createBrowserRouter` + `RouterProvider`). Routes defined in `App.tsx`. Root layout (`routes/__root.tsx`) handles auth guard — redirects to `/login` when not authenticated.
- **Development order**: Follow [dev-spec.md](./dev-spec.md) §九 (Phase roadmap).
- **Auth flow**: Login page → POST `/admin/auth/login` with token → receive admin JWT → store in auth-store → attach as `Authorization: Bearer <jwt>` on all subsequent requests
- **API client**: All admin API calls go through `lib/api-client.ts` (ky v2). Uses `baseUrl` + `prefix: "/admin"`. Auto-attaches auth header. 401 responses trigger logout + redirect to `/login`.
- **Data tables**: TanStack Table v8 headless + shadcn/ui styled components in `components/data-table/`
- **Forms**: React Hook Form + Zod validation for all admin forms
- **State**: Zustand for client state only; server state fetched via API client

## Gotchas

- **shadcn/ui CLI**: After `bunx shadcn@latest add ...`, verify files land in `src/components/ui/` — sometimes they end up in `@/components/ui/` at project root instead.
- **ky v2**: Uses `baseUrl` + `prefix` (not `prefixUrl`). Hooks receive a single state object (`{ request }`, `{ response }`) instead of positional arguments.
- **TypeScript 6**: Requires `"ignoreDeprecations": "6.0"` in tsconfig when using `baseUrl` + `paths` for `@/*` aliases.
- **Tailwind v4**: Uses `@import "tailwindcss"` and `@theme inline` block (not `@tailwind base/components/utilities`).
