Multiple fixes and improvements:
- src/app/api/user/hardcover-shelves/[id]/route.ts: Make token testing more robust by using the existing shelf.apiToken when no new token is provided, attempt decryption only when needed, and gracefully fall back on decryption errors.
- src/components/ui/AddShelfModal.tsx: Simplify token handling by passing the trimmed token directly to addHardcover (remove client-side 'Bearer ' stripping).
- src/components/ui/ManageShelfModal.tsx: Stabilize form reset effect by depending on shelf?.id to avoid unnecessary re-renders when the shelf object changes identity.
- src/components/ui/Modal.tsx: Simplify modal rendering by removing the mounted state and createPortal usage, cleaning up imports and rendering directly.
- src/lib/services/hardcover-api.service.ts: Add a logger, introduce a MAX_PAGES cap and page counters to prevent unbounded pagination loops, and log/break when the API returns errors during pagination.
These changes improve reliability (token handling and pagination safety), reduce unnecessary renders, and simplify modal lifecycle.
Replace the old hardcover sync usage with a new hardcover-api.service implementation that adds types, a reusable extractBooks helper, and paginated GraphQL queries (limit/offset) to fully fetch status and list books. Update API route import to use the new service. Fix ManageShelfModal to initialize rssUrl/listId as empty strings. Update tests to mock the new service and add encryption format helper mocking.
Introduce Hardcover provider support and consolidate per-provider book mapping tables into a unified BookMapping model. Adds two Prisma migrations (add_hardcover_shelves, unify_book_mappings), new backend services (hardcover-api, shelf-sync-core), and provider-specific sync logic and API routes for hardcover shelves with token/list validation. Frontend: new HardcoverForm component, refactor AddShelfModal to support Hardcover, hook updates, and small UI/accessibility tweaks. Also add documentation for Goodreads and Hardcover sync flows and update tests to cover scheduler/prisma helpers.
