Deploy

CI (.github/workflows/deploy.yml) builds and pushes to Cloudflare Pages on every push to main, but a few things only need to be set up once, by hand, in the Cloudflare account:

1. Create the D1 database (one-time):

   npx wrangler d1 create hotfridge
   

   Copy the returned database_id into wrangler.jsonc's d1_databases[0].database_id (replacing the REPLACE_WITH_DATABASE_ID_FROM_WRANGLER_D1_CREATE placeholder) and commit it — it's not a secret.

2. Apply migrations to the remote database (needed again after every new migration):

   npx wrangler d1 migrations apply hotfridge --remote
   

3. Bind the D1 database to the Pages project — in the Cloudflare dashboard, open the hotfridge Pages project → Settings → Functions → D1 database bindings, and add a binding named DB pointing at the hotfridge database. (Pages projects configure bindings via the dashboard, not wrangler.jsonc, even though wrangler.jsonc is what local dev and wrangler d1 commands read.)

4. Set the Gemini API keys as a server secret — add a repository Actions secret named GEMINI_API_KEYS. Its value is a comma-separated list (key-one,key-two). CI uploads it to the Pages runtime; Gemini calls and key rotation happen only on the server.

5. Actions secrets — the workflow needs CLOUDFLARE_API_TOKEN, CLOUDFLARE_ACCOUNT_ID, GEMINI_API_KEYS, GUIDE_JOB_SECRET, VAPID_SUBJECT, VAPID_PUBLIC_KEY, and VAPID_PRIVATE_KEY set as repository Actions secrets. The VAPID public key is the base64url-encoded 65-byte uncompressed P-256 point; the private key is the matching base64url JWK d value.

6. Deploy the scheduled worker after changing workers/recommendation-workflow.ts or wrangler.workflow.jsonc:

   bun run deploy:workflow
   printf '%s' "$GUIDE_JOB_SECRET" | bunx wrangler secret put GUIDE_JOB_SECRET --config wrangler.workflow.jsonc
   

   The worker runs every five minutes and triggers both recommendation generation and near-expiry push delivery.

Steps 1–2 also apply locally for bun run dev (use --local instead of --remote), and the comma-separated Gemini keys locally go in .env (see .env.example).
