reader-api (FastAPI + UV)

Shared backend API for both:

• Web app: reader
• Mobile app: reader-app

This project is Python-first (FastAPI), with production-focused Docker setup and healthcheck.

Stack

• Python 3.11+
• FastAPI
• UV (package manager / runner)
• PostgreSQL (structured data)
• MongoDB (chapter content + user recommendations)

API Base URL

• Local dev: http://localhost:8000
• Healthcheck: GET /api/health

Environment

Create .env from .env.example.

Required keys:

DATABASE_URL=postgresql://reader:reader@localhost:5432/reader
MONGODB_URI=mongodb://localhost:27017/reader
NEXTAUTH_SECRET=replace-with-strong-secret
MOBILE_JWT_SECRET=replace-with-strong-secret
# Comma-separated allowed Google OAuth client IDs
GOOGLE_CLIENT_ID=web-client-id.apps.googleusercontent.com,android-client-id.apps.googleusercontent.com
CORS_ORIGINS=http://localhost:3000,http://127.0.0.1:3000
APP_ENV=development

Dev Setup (UV)

1. Install UV

curl -LsSf https://astral.sh/uv/install.sh | sh

2. Sync dependencies

uv sync

3. Run API in dev mode

uv run uvicorn app.main:app --reload --host 0.0.0.0 --port 8000

4. Verify health

curl http://localhost:8000/api/health

Docker Compose

Current docker-compose.yml supports a unified deployment for both web + API.

Web + API (use external DBs)

docker compose up -d --build api web

Required env for web OAuth in .env:

WEB_GOOGLE_CLIENT_ID=web-client-id.apps.googleusercontent.com
WEB_GOOGLE_CLIENT_SECRET=replace-with-web-google-client-secret

Full local stack (API local + Postgres + Mongo)

docker compose --profile localdb up -d --build api-local postgres mongo

Notes:

• api listens on port 8000 and is intended for external DB deployments.
• api-local listens on port 8001 and automatically points to postgres + mongo containers.
• web listens on port 3000 and calls API internally through http://api:8000.

NAS mount points (chapter content + EPUB source)

API containers now reserve two mount folders:

• /data/content: converted chapter files (txt + raw_html)
• /data/epub-source: source EPUB library

Default env mapping (already wired in compose):

NAS_CONTENT_ROOT=/data/content
EPUB_SOURCE_ROOT=/data/epub-source

If you want to bind to host folders for local testing:

services:
  api:
    volumes:
      - /absolute/local/path/content:/data/content
      - /absolute/local/path/epub-source:/data/epub-source

If you want to use NFS-backed docker volumes, define them under volumes:. Example:

volumes:
  nas_chapter_content:
    driver: local
    driver_opts:
      type: nfs
      o: addr=100.93.79.10,nolock,soft,rw
      device: ":/volume2/apps/reader-content"

  nas_epub_source:
    driver: local
    driver_opts:
      type: nfs
      o: addr=100.93.79.10,nolock,soft,rw
      device: ":/volume2/apps/reader-epub"

For your EPUB structure (folder per novel, multiple .epub parts inside), mount the parent folder to /data/epub-source.

NAS Migration Ops

1) Apply SQL migration manually

Run SQL in migrations/2026_04_nas_content_storage.sql against PostgreSQL.

2) Backfill existing chapter content from Mongo -> NAS + ChapterContentRef

Dry-run first:

python scripts/backfill_chapter_content_refs.py --limit 1000 --dry-run

Then execute:

python scripts/backfill_chapter_content_refs.py --limit 1000

You can run multiple batches by increasing/changing --limit.

Checkpoint/resume mode:

python scripts/backfill_chapter_content_refs.py --limit 1000 --state-file .backfill_state.json

Or continue from a known ObjectId:

python scripts/backfill_chapter_content_refs.py --limit 1000 --after-id 680f7f3a2f0d53f4f2b7a123

Chapter Read Cutover Flag

Set in .env:

CHAPTER_CONTENT_MODE=nas_first

Values:

• nas_first (default): read NAS ref first, fallback Mongo.
• mongo_first: keep Mongo-first during cautious rollout.

Notes

• Web session auth is supported via NextAuth session cookies (next-auth.session-token and secure variants).
• Mobile auth is supported via Bearer JWT from /api/auth/mobile-login.
