MODULE 14 · LIVE ON VERCEL, AND STAYING LIVE
Deployment
One push. One deploy. Every tier.
The frontend goes to Vercel in every tier; from Tier 2 the backend deploys beside it. Environments stay separate — dev, preview, production — and rollback is a button you've already pressed once on purpose.
WHEN YOU NEED IT
Every tier. Deploy on day one, not launch day.
THE CHOICE, PER TIER
- T0–1Vercel, connected to the GitHub repo
- T2+ backend on Railway / Render / Cloud Run
- T3+ health checks and a written rollback plan
SAY THIS TO YOUR AGENT
"Connect the repo to Vercel with preview deploys per PR. Production env vars set in the dashboard, never committed. Show me how to roll back, and we practice it once."
DONE WHEN
- git push deploys automatically with previews per PR
- Prod secrets exist only in the host's env settings
- You have rolled back once, on purpose, calmly
