# CLAUDE.md

## Commands

```bash
# Root commands (via Turborepo)
bun run dev              # Start API server + Vite dev server
bun run build            # Production build (both apps)
bun run lint             # Biome lint check
bun run format           # Biome format (auto-fix)
bun run check-types      # TypeScript type check
bun run test             # Run tests

# Database commands (run from packages/db/)
cd packages/db && bun run db:push       # Push schema changes to SQLite database
cd packages/db && bun run db:generate   # Generate Drizzle migration files
cd packages/db && bun run db:migrate    # Run Drizzle migrations
cd packages/db && bun run db:studio     # Open Drizzle Studio (visual DB browser)
```

**Use Bun, not Node.js** — `bun <file>`, `bun test`, `bun install`, `bun run <script>`, `bunx <pkg>`. Bun auto-loads `.env`.

## Pre-commit checks

All three must pass with zero warnings or errors:

```bash
bun run lint
bun run check-types
bun run test
```

## Architecture

**Sofa** is a self-hosted movie & TV tracking app built as a Turborepo monorepo.

All shared packages are JIT (raw TypeScript exports, no build step).

### Apps

- **`@sofa/server`** — Hono API server. Hosts oRPC procedures, Better Auth, webhook/image/backup routes, and cron jobs. Runs DB migrations on startup. Dev: port 3001. Prod: serves SPA static files too, port 3000.
- **`@sofa/web`** — Vite SPA with TanStack Router (file-based routing). No SSR, no DB. All data via oRPC. Vite dev server proxies `/api/*` and `/rpc/*` to the API server.
- **`@sofa/native`** — Expo Router app with 4-tab layout (Home, Explore, Search, Settings). UniWind for styling, `@better-auth/expo` with SecureStore for auth, oRPC client for API calls. Dark-only cinema theme matching web.

### Stack

- **Frontend**: Vite 7 SPA, React 19, TanStack Router (file-based), Tailwind CSS v4, shadcn, Jotai
- **Mobile**: Expo 55, Expo Router, UniWind (Tailwind for RN), `@tabler/icons-react-native`
- **API**: Hono on Bun, oRPC (contract-first) with `@orpc/tanstack-query`
- **Database**: SQLite via `bun:sqlite` + Drizzle ORM (WAL mode, sync queries, auto-migrations)
- **Auth**: Better Auth with Drizzle adapter — email/password + optional OIDC/SSO
- **Monorepo**: Turborepo with Bun workspaces
- **Linting**: Biome (2-space indent, organized imports)
- **External API**: TMDB (The Movie Database)

### Package imports

Path aliases: `@/*` maps to `src/` in both `apps/web/` and `apps/native/`.

Cross-package imports:
- `@sofa/api/contract`, `@sofa/api/schemas` — Contract and Zod types
- `@sofa/db/client`, `@sofa/db/schema`, `@sofa/db/helpers`, `@sofa/db/migrate`, `@sofa/db/test-utils`
- `@sofa/tmdb/client`, `@sofa/tmdb/image`
- `@sofa/core/metadata`, `@sofa/core/tracking`, etc.
- `@sofa/auth/server`, `@sofa/auth/config`
- `@sofa/config` — Path constants (`DATA_DIR`, `DATABASE_URL`, `CACHE_DIR`, `BACKUP_DIR`, `AVATAR_DIR`) and TMDB URLs
- `@sofa/logger` — `createLogger(name)` for structured logging

### Key patterns

**oRPC queries** use `orpc.*.queryOptions()` with TanStack Query. **Mutations** use `client.*()` directly. **Route loaders** prefetch via `queryClient.ensureQueryData()`.

**Auth guards** — Web routes use `beforeLoad` + `authClient.getSession()`. API procedures use auth middleware that calls `auth.api.getSession()`.

**TMDB images** — Only paths stored in DB. The API server resolves full URLs via `tmdbImageUrl()`. When `IMAGE_CACHE_ENABLED` (default), images are downloaded to disk and served via `/images/:category/:filename`.

**Database IDs** — All app tables use UUIDv7 text PKs via `Bun.randomUUIDv7()`.

### Environment variables

Required: `TMDB_API_READ_ACCESS_TOKEN`, `BETTER_AUTH_SECRET`, `BETTER_AUTH_URL`.

Optional:
- `DATA_DIR` — Root for DB + cache (default `./data`). `DATABASE_URL` and `CACHE_DIR` derived from it but overridable.
- `TMDB_API_BASE_URL`, `TMDB_IMAGE_BASE_URL` — Override TMDB endpoints.
- `PUBLIC_API_URL` — Base URL for centralized public API (default: `https://public-api.sofa.watch`). Used for update checks.
- `IMAGE_CACHE_ENABLED` — Default `true`. Set `false` for direct TMDB CDN URLs.
- `LOG_LEVEL` — `error`/`warn`/`info`/`debug` (default: `info`).
- OIDC: `OIDC_CLIENT_ID`, `OIDC_CLIENT_SECRET`, `OIDC_ISSUER_URL`, `OIDC_PROVIDER_NAME`, `OIDC_AUTO_REGISTER`, `DISABLE_PASSWORD_LOGIN`.

### Testing

Tests live in `packages/core/test/`. `preload.ts` mocks `@sofa/db/client` with in-memory SQLite. Never mock a service module with stubs — `bun`'s `mock.module` persists across test files.

### Docker

Single container, single process. Hono serves API + SPA on port 3000. API routes (`/rpc/*`, `/api/*`) mounted first; unmatched routes fall back to `index.html`.

## Browser Automation

Use `agent-browser` for web automation (`agent-browser --help` for all commands). Auth credentials: `demo@sofa.watch` / `password`.
