• My Library — browse and search your reading history, grid/list view, edit entries
• "Have I read this?" — quick search against your own library
• Ratings — rate books 0–5 stars when logging or editing
• Public feed — anonymous feed of recently logged books on the homepage
• Google OAuth — sign in with your Google account

Getting started

npm install
cp .env.example .env    # fill in your values
npx prisma generate
npx prisma db push      # local/dedicated databases only — on a shared database use `prisma db execute` with migration SQL
npm run dev

Testing

npm test              # run all tests
npm run test:coverage # run with coverage report

90 tests across 5 suites covering API integrations, server actions, and components.

Quality gates

• Pre-commit — ESLint + Prettier via lint-staged
• Pre-push — TypeScript type-check, ESLint, and full test suite
• CI — GitHub Actions runs lint, type-check, and tests with coverage on pushes to master and on pull requests targeting master

External APIs

• Open Library — book search by title/author, no API key required
• Google Books — secondary search source, requires GOOGLE_BOOKS_API_KEY

Results from both APIs are searched in parallel and deduplicated.
