Cloudflare Workers Setup — Linear Void

Linear Void uses Cloudflare Workers for two purposes:

Product Purpose What
Workers Static SPA hosting Vite-built frontend (frontend/dist) served as Worker static assets
Workers Edge cache logic infrastructure/cloudflare/worker.js — adds immutable cache headers to HLS segments

Both are managed under Workers & Pages in the Cloudflare dashboard.

Worker: linearvoid (edge cache headers)

The Worker at infrastructure/cloudflare/worker.js runs on the linearvoid Workers service. It intercepts requests and adds immutable Cache-Control headers to .m4s segment files.

Deploy via Wrangler CLI:

npx wrangler deploy infrastructure/cloudflare/worker.js

Or paste into the Workers dashboard at the URL above (Quick Edit).

Worker: static frontend

Serve the Vite-built SPA (frontend/dist) as Worker static assets:

  1. Build the frontend: cd frontend && npm run build.
  2. Bind frontend/dist to the Worker as static assets (Workers Static Assets / assets in wrangler.toml).
  3. Attach the linearvoid.tv custom domain to the Worker.

See gitea-cloudflare-workers.md for the automated deployment workflow.

Build-time variables

The VITE_PUBLIC_* values are baked into the bundle at build time by Vite (vite.config.ts uses envDir: ".." to read them from the repo root). They are supplied by the Gitea Actions build environment from Gitea secrets — not as Worker runtime variables. The static-assets Worker has no runtime JavaScript, so it reads no env at request time.

Name Value
VITE_PUBLIC_APP_URL https://linearvoid.tv
VITE_PUBLIC_WS_URL wss://linearvoid.tv/ws
VITE_PUBLIC_HLS_URL https://media.linearvoid.tv/hls/playlist.m3u8
VITE_PUBLIC_ADMIN_DEFAULT_MODERATOR boogers
VITE_PUBLIC_ADMIN_DEFAULT_ROOM main
VITE_PUBLIC_ADMIN_MODERATION_LOG_LIMIT 50

Backend services (playout, chat, nginx) read their own runtime variables (ADMIN_*, HLS_*, PLAYLIST_PATH, R2_*, DATABASE_URL, REDIS_URL) from the container environment — see .env.example.

Custom domains

  • linearvoid.tv → Worker (static SPA)
  • www.linearvoid.tv → redirect to linearvoid.tv
  • media.linearvoid.tv → R2 bucket (separate; not a Worker)
