Follow lists were paginated at the API default of 48, but the SPA treats them as complete sets: the tag/pool toggles read their state from page one (so the 49th follow looked unfollowed and its spinner waited for a page that could never contain it) and the Followed page rendered only 48 cards while showing that as the count. Both follow endpoints are now unpaginated — they are per-user sets and still restricted to the caller's rows — and the three consumers take plain arrays. Post visibility: the old J621-Django online view fetched limit=320 (e621's maximum) while ours hard-coded 48, and fetchPostsByIds capped id batches at 100. The Online browser now has a 'Posts per page' setting (48/100/200/320) in its sidebar, mirrored in Account -> Browsing preferences, stored per user as e621_per_page and also used for pool loading; the id-batch cap is raised to 320. Tests: follow list shape/isolation (4) and preference validation/merge (3) added; the full backend suite is 46 green. Live-checked the array response shape and the preference bounds (200 accepted, 500 rejected).
J621
Self-hosted media library and e621 archive manager, rebuilt as a React SPA + Django REST API.
Structure
backend/ Django 6 + DRF API (MariaDB + Redis via docker compose)
frontend/ Vite + React + TypeScript SPA
deploy/ Docker images, compose variants and Tailscale serve configs
extras/ shell integrations (fish_greeting with fastfetch)
Development
Backend
cd backend
source venv/bin/activate
python manage.py migrate
python manage.py scan_files # index the watched folder
python manage.py runserver
Copy .env.example to .env and set WATCHED_FOLDER before scanning.
Frontend
cd frontend
npm install
npm run dev # http://localhost:5173, proxies /api to :8000
Production
Docker: see deploy/ for the two images (SPA on static
nginx, API on gunicorn), the three compose variants (both / frontend-only /
backend-only) behind a shared nginx service and a Tailscale sidecar, and the
public-funnel or tailnet-only serve configs. deploy/push_*.sh builds and
pushes the multi-arch images to the Gitea registry.
Random image endpoint
Used by the SPA's Random page and by shell greetings (fish_greeting + fastfetch):
curl -H "Authorization: Token <token>" \
"https://j621.example.ts.net/api/random/?rating=s,q&fastfetch=1"
{
"j_id": "J-59",
"filename": "J-59.jpg",
"extension": "jpg",
"rating": "e",
"url": "https://j621.example.ts.net/api/files/J-59/raw/?sig=…",
"download_url": "https://j621.example.ts.net/api/files/J-59/raw/?sig=…&download=1",
"thumbnail_url": "https://j621.example.ts.net/api/files/J-59/thumbnail/?sig=…",
"fastfetch": true
}
