Deployment Infrastructure

See deployment-config.md for full architecture, env vars, cron jobs, caching headers.

Environment Variables

Precedence: .env (committed defaults) → .env.local (git-ignored) → .env.production / .env.preview → platform-injected (highest). Gitignore .env.local, .env.*.local.

Validate the whole environment with one Zod schema at startup, not at point of use. SCREAMING_SNAKE_CASE; PUBLIC_*/NEXT_PUBLIC_* is browser-exposed, SECRET_*/*_SECRET server-only.

CI/CD Pipeline

main → production, feature/* and fix/* → preview, all automatic. Stages in order: install (always --frozen-lockfile in CI) → lint → test → production build → deploy.

Cron route handlers must return 401 unless the authorization header equals Bearer ${process.env.CRON_SECRET}.

Caching Strategy

Set per-asset via framework headers() config or CDN rules — never a blanket no-store.

Asset TypeCache-Control

Security Headers

Release & Rollback

Gate a release on lint + test + build all exiting 0 and no draft PRs, then semver-tag with a changelog categorized Features / Fixes / Breaking. Verify with curl -sI https://example.com | grep -E 'HTTP|Strict' — homepage 200, headers correct.

A failed release gets rolled back immediately, not patched forward. Prefer platform rollback (promote last good deploy) over git revert -m 1 HEAD && git push; re-run the curl -sI check before calling it resolved.
