Coolify attaches the container to its proxy network and routes to the exposed port, so the host publish was redundant and additionally reachable on 0.0.0.0:3000 outside TLS. Left commented for standalone `docker compose up`.
wheelofnames
Self-hosted API that renders wheel-of-names GIF animations with Remotion.
API
POST /api/gif
Content-Type: application/json
Accept: image/gif
Authorization: Bearer change-me
{
"options": ["alice", "bob", "carol"],
"winnerIndex": 1,
"durationMs": 6500,
"holdMs": 1200,
"fps": 15,
"size": 512,
"theme": "classic"
}
Response is image/gif with winner metadata headers:
X-Wheel-Winner-IndexX-Wheel-WinnerX-Render-Duration-Ms
X-Wheel-Winner is URL-encoded so non-ASCII labels are safe in HTTP headers.
Local
Install dependencies and Chromium once:
npm install
npm run browser:ensure
Start the local API:
npm run dev
Generate GIF files locally
Generate the quick smoke fixture at the git-ignored path
fixtures/smoke.gif:
npm run render:smoke
Generate the complete fixture set at fixtures/smoke.gif,
fixtures/vietnamese.gif, and fixtures/sixteen-options.gif:
npm run render:fixtures
Render a custom GIF directly without starting the API server:
npm run render:local -- `
--output wheel.gif `
--option "Chiều nay uống CraneTea" `
--option "Chiều nay uống CraneTea" `
--option "Cà phê" `
--winner 1
macOS, Linux, or Git Bash:
npm run render:local -- \
--output wheel.gif \
--option "Chiều nay uống CraneTea" \
--option "Chiều nay uống CraneTea" \
--option "Cà phê" \
--winner 1
--winner is a zero-based index and is random when omitted. Run
npm run render:local -- --help for duration, hold, FPS, size, theme, and timeout
options. The documented root wheel.gif and fixtures/*.gif outputs are
git-ignored and safe to delete; custom output paths may need their own ignore
rule.
Verify
Run the API smoke test and quality gates:
npm run api:smoke
npm run lint
npm run typecheck
npm test
Deploy
Use a container runtime first. Static-only platforms cannot satisfy
POST /api/gif because Remotion server rendering needs Node, Chromium/runtime
dependencies, and FFmpeg/compositor support.
docker build -t wheelofnames .
docker run --rm -p 3000:3000 -e API_TOKEN=change-me wheelofnames
Recommended starting resources: 1-2 vCPU and 1-2 GB RAM, with
MAX_CONCURRENT_RENDERS=1. RENDER_TIMEOUT_MS defaults to 15000 and is
raised to Remotion's 7000ms browser timeout floor when configured lower.
API_TOKEN is required when NODE_ENV=production.
