## Routes

The app uses a two-section layout architecture:

### Chat Section (`/`)

| Path | Name | Component | Description |
|------|------|-----------|-------------|
| `/` | home | `home/index.vue` | Home — empty state when no bot selected |
| `/chat/:botId?/:sessionId?` | chat | `home/index.vue` | Chat interface with bot + session params |

Both routes render the same `home/index.vue` component. The `home` route shows an empty state; the `chat` route auto-selects a bot and optionally a session based on URL params. URL and store state are bidirectionally synced.

### Settings Section (`/settings`)

| Path | Name | Component | Description |
|------|------|-----------|-------------|
| `/settings/bots` | bots | `bots/index.vue` | Bot list grid |
| `/settings/bots/:botId` | bot-detail | `bots/detail.vue` | Bot detail with tabs |
| `/settings/providers` | providers | `providers/index.vue` | LLM provider & model management |
| `/settings/web-search` | web-search | `web-search/index.vue` | Web search provider management |
| `/settings/memory` | memory | `memory/index.vue` | Memory provider management |
| `/settings/speech` | speech | `speech/index.vue` | TTS / speech provider & model management |
| `/settings/email` | email | `email/index.vue` | Email provider management |
| `/settings/browser` | browser | `browser/index.vue` | Browser context management |
| `/settings/supermarket` | supermarket | `supermarket/index.vue` | Template/skill marketplace |
| `/settings/usage` | usage | `usage/index.vue` | Token usage statistics |
| `/settings/profile` | profile | `profile/index.vue` | User profile settings |
| `/settings/platform` | platform | `platform/index.vue` | Platform management |
| `/settings/about` | about | `about/index.vue` | About page |

`/settings` redirects to `/settings/bots` by default.

### Standalone Routes

| Path | Name | Component | Description |
|------|------|-----------|-------------|
| `/login` | Login | `login/index.vue` | Login form (no auth required) |
| `/oauth/mcp/callback` | oauth-mcp-callback | `oauth/mcp-callback.vue` | MCP OAuth callback (no auth required) |

### Auth Guard

- All routes except `/login` and `/oauth/*` require `localStorage.getItem('token')`.
- Logged-in users accessing `/login` are redirected to `/`.
- Chunk load errors (dynamic import failures) trigger an automatic page reload.
- Tauri integration: `afterEach` hook calls `resize_for_route` via `@tauri-apps/api/core` when running inside Tauri.

## Layout System

Two-section layout architecture, both sharing the same `MainLayout` wrapper:

1. **MainLayout** (`layout/main-layout/`) — Top-level wrapper using `SidebarProvider` from `@memohai/ui`. Provides `#sidebar` and `#main` slots.

2. **Chat Section** (`pages/main-section/`) — Uses `MainLayout` with:
   - **Sidebar** (`components/sidebar/`) — Bot list sidebar (collapsible). Header shows "Bots" label + create button. Body lists all bots as `BotItem` entries. Footer has a settings gear link to `/settings`.
   - **MainContainer** (`components/main-container/`) — `<KeepAlive>` wrapped `<RouterView>` for chat pages.

3. **Settings Section** (`pages/settings-section/`) — Uses `MainLayout` with:
   - **SettingsSidebar** (`components/settings-sidebar/`) — Collapsible settings navigation. Top has a "back to chat" button that restores the last selected bot/session. Menu items: Bots, Providers, Web Search, Memory, Speech, Email, Browser, Supermarket, Usage, Profile, About.
   - **SidebarInset** — `<KeepAlive>` wrapped `<RouterView>` for settings pages.

4. **Home/Chat Page** (`pages/home/`) — Internal layout:
   - **SessionSidebar** — Left panel: session search, source filter, new session button, session list.
   - **ChatArea** — Center panel: message list with scroll, input area with attachments.
   - **SessionInfoPanel** — Right panel: session info display.

Several settings pages use **MasterDetailSidebarLayout** (`components/master-detail-sidebar-layout/`) for left-sidebar + detail-panel patterns (providers, web search, email, memory, speech, browser).

## CSS & Theming

Design tokens, color palette, typography, elevation strategy, and component visual specs are defined in `packages/ui/DESIGN.md`. **Read that file before making any UI changes.**

### Tailwind CSS 4

CSS-based configuration (no `tailwind.config.*` file). All design tokens (CSS variables, `@theme inline` mapping, base styles) live in `packages/ui/src/style.css`. The web app imports them via:

```css
@import "@memohai/ui/style.css";
```

### Dark Mode

- Runtime: `useColorMode` from `@vueuse/core` in `store/settings.ts`
- Storage: theme preference persisted via `useStorage`
- Toggle: Available in Settings page and login page
- Usage: semantic tokens auto-switch; no `dark:` prefix needed

### Styling Rules

- Use Tailwind utility classes; avoid `<style>` blocks.
- Always use semantic color tokens (`text-foreground`, `bg-card`, `border-border`, etc.) — never hardcode raw colors (`gray-*`, `bg-white`, `text-black`).
- Follow the design system rules in `packages/ui/DESIGN.md`.

## UI Components (@memohai/ui)

All UI primitives are provided by `@memohai/ui` (43 component groups built on Reka UI). Do not import Reka UI directly. For the component design specification (variants, colors, elevation, spacing), see `packages/ui/DESIGN.md`.

- **Exception**: Physical UI knobs (Switch thumb, Slider thumb) may keep `bg-white` as they need to contrast against colored tracks regardless of theme.
- **No scoped CSS modules**: Styling is done inline via utility classes.

### CSS Imports (main.ts)

```
style.css                    — Tailwind + theme tokens
animate.css                  — Animation utilities
markstream-vue/index.css     — Markdown rendering
katex/dist/katex.min.css     — Math rendering
vue-sonner/style.css         — Toast notifications (in App.vue)
```

`@memohai/ui` provides 43 component groups built on Reka UI primitives + Tailwind + class-variance-authority:

- **Form**: `Form`, `FormField`, `FormFieldArray`, `FormItem`, `FormControl`, `FormLabel`, `FormMessage`, `FormDescription`
- **Input**: `Input`, `Textarea`, `InputGroup` (Addon, Button, Input, Text, Textarea), `NativeSelect`, `Combobox`, `TagsInput`, `InputOTP` (Group, Slot, Separator)
- **Selection**: `Select`, `RadioGroup`, `Checkbox`, `Switch`, `Toggle`, `Slider`
- **Layout**: `Card`, `Separator`, `Sheet`, `Sidebar` (24 sub-components), `ScrollArea`, `Collapsible`, `Item` (10 sub-components)
- **Overlays**: `Dialog` (incl. `DialogScrollContent`), `Popover`, `Tooltip`, `DropdownMenu`, `ContextMenu`, `Command` (Dialog, Group, Input, Item, List)
- **Data**: `Table` (9 sub-components), `Badge`, `BadgeCount`, `Avatar`, `Skeleton`, `Empty` (5 sub-components)
- **Navigation**: `Breadcrumb`, `Tabs`, `Pagination`, `PinInput` (Group, Slot, Separator)
- **Feedback**: `Button`, `ButtonGroup` (Separator, Text), `Spinner`, `Alert`, `Toaster` (Sonner), `Kbd`
- **Effects**: `TextGenerateEffect`

### Form Pattern (vee-validate + Zod)

```vue
<script setup>
const form = useForm({
  validationSchema: toTypedSchema(z.object({
    name: z.string().min(1),
  })),
})
</script>

<template>
  <FormField v-slot="{ componentField }" name="name">
    <FormItem>
      <Label>Name</Label>
      <FormControl>
        <Input v-bind="componentField" />
      </FormControl>
      <FormMessage />
    </FormItem>
  </FormField>
</template>
```

### Icon Usage

- **Lucide** (primary): Direct component imports from `lucide-vue-next`. Example: `import { Plus, Search, Bot } from 'lucide-vue-next'` → `<Plus class="size-4" />`. Used for all UI icons (actions, navigation, status indicators, etc.).
- **`@memohai/icon`** (brand icons): Workspace package (`packages/icons/`) providing AI provider, search engine, and channel platform SVG icons as Vue components. Example: `import { Openai, Claude } from '@memohai/icon'`.
- **Do NOT use FontAwesome** for new code. Legacy FontAwesome usage remains only in commented-out code blocks. Always use Lucide for UI icons and `@memohai/icon` for brand logos.

### Notification Pattern

```typescript
import { toast } from 'vue-sonner'
toast.success(t('common.saved'))
toast.error(resolveApiErrorMessage(error, 'Failed'))
```

## Data Fetching

### API Client Setup (`lib/api-client.ts`)

- SDK: `@memohai/sdk` auto-generated from OpenAPI via `@hey-api/openapi-ts`
- Base URL: `VITE_API_URL` env var (defaults to `/api`, proxied by Vite dev server to backend)
- Auth: Request interceptor attaches `Authorization: Bearer ${token}` from localStorage
- 401 handling: Response interceptor removes token and redirects to `/login`

### Pinia Colada (Server State)

Primary data fetching mechanism for CRUD operations:

```typescript
// Query — auto-generated from SDK
const { data, isLoading } = useQuery(getBotsQuery())

// Custom query with dynamic key
const { data } = useQuery({
  key: () => ['bot-settings', botId.value],
  query: async () => {
    const { data } = await getBotsByBotIdSettings({
      path: { bot_id: botId.value },
      throwOnError: true,
    })
    return data
  },
  enabled: () => !!botId.value,
})

// Mutation with cache invalidation
const queryCache = useQueryCache()
const { mutateAsync } = useMutation({
  mutation: async (body) => {
    const { data } = await putBotsByBotIdSettings({
      path: { bot_id: botId.value },
      body,
      throwOnError: true,
    })
    return data
  },
  onSettled: () => queryCache.invalidateQueries({
    key: ['bot-settings', botId.value],
  }),
})
```

SDK also generates colada helpers: `getBotsQuery()`, `postBotsMutation()`, query key factories.

### Pinia Stores (Client State)

| Store | ID | Purpose |
|-------|----|---------|
| `user` | `user` | JWT token (`useLocalStorage`), user info (id, username, role, displayName, avatarUrl, timezone), login/logout |
| `settings` | `settings` | Theme (dark/light), language (en/zh), synced with `useColorMode` and vue-i18n locale |
| `capabilities` | `capabilities` | Server feature flags (container backend, snapshot support), loaded once from `getPing()` |
| `chat-selection` | `chat-selection` | Current bot ID and session ID, persisted via `useStorage` to localStorage |
| `chat-list` | `chat` | Chat messages, sessions, bots, streaming state, SSE/WS event processing. Depends on `chat-selection` store for current bot/session. Utility functions in `chat-list.utils.ts` |

Additional stores in `stores/`:
| Store | Purpose |
|-------|---------|
| `supermarket-mcp-draft` | Supermarket MCP draft state management |

Stores use Composition API style (`defineStore(() => { ... })`), with persistence via `pinia-plugin-persistedstate` or `useStorage`.

### Streaming (Chat)

Chat supports two transport modes: **Server-Sent Events (SSE)** and **WebSocket**.

#### SSE Streaming
- **Endpoints**: `/bots/{bot_id}/local/stream` (send + stream), `/messages/events` (real-time message updates)
- **Parsing**: `composables/api/useChat.sse.ts` reads `ReadableStream<Uint8Array>` and parses SSE `data:` lines
- **Events**: `text_delta`, `reasoning_delta`, `tool_call_start/end`, `attachment_delta`, `processing_completed/failed`
- **Retry**: `useRetryingStream` composable provides exponential backoff for reconnection

#### WebSocket
- **Endpoint**: `/bots/{bot_id}/local/ws` (with token query param)
- **Implementation**: `composables/api/useChat.ws.ts` wraps native `WebSocket` with send, abort, close, and auto-reconnect
- **State**: `store/chat-list.ts` processes streaming events from either transport into reactive message blocks in real-time
- **Abort**: Stream cancellation via `AbortSignal` (SSE) or close message (WS)

### Error Handling

- **Global**: `utils/api-error.ts` — `resolveApiErrorMessage()` extracts error from `message`, `error`, `detail` fields
- **Mutations**: `useDialogMutation` composable wraps mutations with automatic `toast.error()` on failure
- **SDK**: All calls use `throwOnError: true`; try/catch at component level
- **Streams**: `processing_failed` / `error` events appended to message blocks

## i18n

- Plugin: vue-i18n (Composition API, `legacy: false`)
- Locales: `en` (English, default), `zh` (Chinese)
- Files: `src/i18n/locales/en.json`, `src/i18n/locales/zh.json`
- Usage: `const { t } = useI18n()` → `t('bots.title')`
- Key namespaces: `common`, `auth`, `sidebar`, `breadcrumb`, `settings`, `about`, `chat`, `models`, `provider`, `webSearch`, `memory`, `speech`, `email`, `browser`, `mcp`, `home`, `bots`, `usage`, `supermarket`

## Vite Configuration

- Dev server port: 8082 (from `config.toml`)
- Proxy: `/api` → backend (default `http://localhost:8080`)
- Aliases: `@` → `./src`, `#` → `../ui/src`
- Config: reads from `MEMOH_CONFIG_PATH` / `CONFIG_PATH` when provided, otherwise `../../config.toml`, via `@memohai/config`

## Development Rules

- Use Vue 3 Composition API with `<script setup>` exclusively.
- Style with Tailwind utility classes; avoid `<style>` blocks. Follow the design system in `packages/ui/DESIGN.md`.
- **Always use semantic color tokens** (`text-foreground`, `bg-card`, `border-border`, `text-muted-foreground`, `bg-accent`, etc.) instead of raw colors (`gray-*`, `bg-white`, `text-black`). Never introduce hardcoded Tailwind color classes for themed elements — this breaks dark mode consistency.
- Use `@memohai/ui` components for all UI primitives; do not import Reka UI directly.
- Use `lucide-vue-next` for all UI icons. Use `@memohai/icon` for brand/provider logos. **Never use FontAwesome** — do not add `<FontAwesomeIcon>`, do not import from `@fortawesome/*`, do not use inline SVG or base64-encoded SVG in templates.
- Use Pinia Colada (`useQuery`/`useMutation`) for server state; use Pinia stores for client state only.
- API calls must go through `@memohai/sdk`; never call `fetch()` directly.
- All user-facing strings must use i18n keys (`t('key')`) — never hardcode text.
- Forms must use vee-validate + Zod schemas via `toTypedSchema()`.
- Error messages via `resolveApiErrorMessage()` + `toast.error()`.
- Page components go in `pages/{feature}/`; page-specific sub-components go in `pages/{feature}/components/`.
- Page-specific composables go in `pages/{feature}/composables/`.
- Shared components go in `components/`.
- Composables go in `composables/`; API-specific composables in `composables/api/`.
