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

# 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/.

Git Worktrees

Always use pnpm worktree:new <branch-name|pr-number> to create worktrees. Never use git worktree add directly — the script handles submodule initialization (simplecc WASM, foliate-js), dependency installation, .env copying, vendor assets, and Tauri gen symlinks that are required for lint and tests to pass.

pnpm worktree:new feat/my-feature   # New branch from origin/main
pnpm worktree:new 3837              # Checkout PR #3837 with push access to fork

Project Rules

Rules are in .claude/rules/: test-first, typescript, verification.

i18n

See 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 for rules on handling top/bottom insets for UI elements near screen edges.
