Huang Xin 956c71cd7b chore: migrate from ESLint to Biome for linting (#3694)
Replace ESLint with Biome for ~14x faster linting (~360ms vs ~5s).

- Add biome.json with rules matching ESLint parity (Next.js, a11y,
  TypeScript, unused vars/imports)
- Remove eslint, @typescript-eslint/*, eslint-config-next,
  eslint-plugin-jsx-a11y, @eslint/* from deps
- Remove eslint.config.mjs
- Update lint script to: tsgo --noEmit && biome check .
- Fix 11 real code issues caught by Biome (banned types, explicit any,
  unsafe finally, unreachable code, shadowed names)
- Disable Biome formatter (Prettier stays for Tailwind class sorting)

## Project Overview
Readest is a cross-platform ebook reader built as a **Next.js 16 + Tauri v2** hybrid app. It's part of a pnpm monorepo at `/apps/readest-app/`. The app runs on web (CloudFlare Workers), desktop (macOS/Windows/Linux via Tauri), and mobile (iOS/Android via Tauri).
## Common Commands
```bash
# Development
pnpm dev-web # Web-only dev server (no Rust compilation needed)
pnpm tauri dev # Desktop dev with Tauri (compiles Rust backend)
# Building
pnpm build # Build Next.js for Tauri
pnpm build-web # Build Next.js for web deployment
# Testing (see [docs/testing.md](docs/testing.md) for full details)
pnpm test # Unit tests (vitest + jsdom)
pnpm test -- src/__tests__/utils/misc.test.ts # Run a single test file
pnpm test -- --watch # Watch mode
pnpm test:browser # Browser tests (Chromium via Playwright)
pnpm tauri:dev:test # Start Tauri app with webdriver
pnpm test:tauri # Run Tauri integration tests
# Linting & Formatting
pnpm lint # Biome (linter) + tsgo (type check)
pnpm format # Prettier (runs from monorepo root)
pnpm format:check # Check formatting without writing
# Rust
pnpm fmt:check # Check formatting Rust code (src-tauri)
pnpm clippy:check # Lint Rust code (src-tauri)
```
### Source Layout
| Directory | Purpose |
| ----------------- | ------------------------------------------------------------- |
| `src/app/` | Next.js App Router pages and API routes |
| `src/components/` | React components (reader, settings, library, assistant, etc.) |
| `src/services/` | Business logic: TTS, translators, OPDS, sync, AI, metadata |
| `src/store/` | Zustand state stores |
| `src/hooks/` | Custom React hooks |
| `src/libs/` | Document loaders, payment, storage, sync |
| `src/utils/` | Pure utility functions |
| `src/types/` | TypeScript type definitions |
| `src/context/` | React Context providers (Auth, Env, Sync, etc.) |
| `src/workers/` | Web Workers for background tasks |
| `src-tauri/` | Rust backend: Tauri plugins, platform-specific code |
### Path Aliases (tsconfig)
- `@/*``./src/*`
- `@/components/ui/*``./src/components/primitives/*`
### Rust Backend (`src-tauri/`)
Platform-specific code lives in `src-tauri/src/{macos,windows,android,ios}/`. Custom Tauri plugins are in `src-tauri/plugins/`.
## Project Rules
Rules are in `.claude/rules/`: test-first, typescript, verification.
### i18n
See [docs/i18n.md](docs/i18n.md) for the key-as-content translation approach, `stubTranslation` usage in non-React modules, and extraction workflow.
### Safe Area Insets
See [docs/safe-area-insets.md](docs/safe-area-insets.md) for rules on handling top/bottom insets for UI elements near screen edges.
## Web Browsing & QA (gstack)
For all web browsing, QA testing, and site interaction, use the `/browse` skill from gstack. **Never use `mcp__claude-in-chrome__*` tools directly.**
Available gstack skills:
- `/plan-ceo-review` — CEO/founder-mode plan review
- `/plan-eng-review` — Eng manager-mode plan review
- `/plan-design-review` — Designer's eye review of a live site
- `/design-consultation` — Design system consultation
- `/review` — Pre-landing PR review
- `/ship` — Ship workflow (merge, test, review, bump, PR)
- `/browse` — Fast headless browser for QA and site interaction
- `/qa` — QA test and fix bugs
- `/qa-only` — QA report only (no fixes)
- `/qa-design-review` — Designer's eye QA with fixes
- `/setup-browser-cookies` — Import cookies for authenticated testing
- `/retro` — Weekly engineering retrospective
- `/document-release` — Post-ship documentation update
If gstack skills aren't working, run `cd .claude/skills/gstack && ./setup` to build the binary and register skills.
