Remove all Dexie/IndexedDB code and dependencies, including document and preview caches, local config, onboarding, and migration logic. Replace with server-backed React Query hooks for documents, folders, preferences, onboarding, and progress. Add browser Cache Storage for blob caching of documents, previews, and audio. Update API routes, database schema, and tests to support folder management, onboarding state, and server-side persistence of all user data. Refactor UI and hooks to use server state exclusively, ensuring all user state is synced and portable across devices. BREAKING CHANGE: All user data, preferences, onboarding, and document state are now stored and synced on the server; browser IndexedDB is no longer used. Existing local-only data will not be available after this update.

Framework
- Next.js 15 (App Router, Turbopack in dev)
- React 19
- TypeScript
- pnpm workspaces monorepo
Containerization and runtime
- Docker (linux/amd64 and linux/arm64)
- Shared entrypoint that runs DB migrations by default and can bootstrap embedded SeaweedFS before app startup
Next.js client
- UI: Tailwind CSS, Headless UI, @tailwindcss/typography
- Interactions:
react-dnd,react-dropzone - Server state: TanStack Query (React Query v5)
- Authentication: Better Auth client SDK
- Browser blob performance cache: Cache Storage (evictable; never authoritative)
- Audio playback: Howler.js
- Notifications:
react-hot-toast - Document rendering:
- PDF: react-pdf, pdf.js
- EPUB: react-reader, epubjs
- Markdown/Text: react-markdown, remark-gfm
- Text preprocessing/matching: compromise, cmpstr
- Analytics: Vercel Analytics
Next.js server
- APIs: Route Handlers for sync, blob/content access, migrations, audiobook export, TTS/Whisper proxying
- State sync: request-based today (not realtime push updates)
- Authentication: Better Auth server handlers/adapters with anonymous session support
- Metadata DB: Drizzle ORM with SQLite (
better-sqlite3) by default and optional Postgres (pg)- App tables are manually maintained in Drizzle schema files
- Auth tables are auto-generated by the Better Auth CLI and migrated alongside app tables via Drizzle
- Blob storage: embedded SeaweedFS (
weed mini) by default, or external S3-compatible storage via AWS SDK v3 - TTS providers: OpenAI-compatible API (
openaiSDK), Replicate (replicateclient), DeepInfra, and custom OpenAI-compatible endpoints — credentials are encrypted at rest - Audio pipeline: ffmpeg (
ffmpeg-static) for audiobook assembly,archiverfor export packaging - Utilities:
lru-cachefor in-process caching,fast-xml-parserfor EPUB/XML parsing,uuidfor identifier generation,zodfor schema validation
External compute worker (optional)
Standalone worker package:
@openreader/compute-worker— standalone Node.js compute service containing its private inference and queue runtime- ONNX runtime:
onnxruntime-nodewith@huggingface/tokenizers - Whisper alignment:
onnx-community/whisper-base_timestamped(q4) for word-level timestamps - PDF layout:
Bei0001/PP-DocLayoutV3-ONNXfor document block detection and layout parsing - PDF rendering:
pdfjs-dist,@napi-rs/canvasfor server-side page rasterization - Utilities:
jszip,ffmpeg-static
- ONNX runtime:
- HTTP server: Fastify v5 with a versioned OpenAPI contract
- The Next.js app communicates with the worker only through the versioned HTTP API generated from OpenAPI.
Tooling and testing
- ESLint
- TypeScript
- Playwright end-to-end tests
- Drizzle migration/generation scripts
