# DevOps: CI/CD Pipeline ## What this builds A GitHub Actions workflow that runs automatically on every PR and push to `main`: 1. **Install** — clean dependency install 2. **Lint** — ESLint code quality checks 3. **Type check** — TypeScript strict checks 4. **Test** — Vitest unit and integration tests (the canonical scaffold ships Vitest; on a Jest project use `npx jest --ci --passWithNoTests` instead — `--ci` is a Jest flag and Vitest rejects it) 5. **Build** — Next.js production build (catches build-time errors before they reach Vercel) Vercel handles preview and production deployments automatically via its GitHub integration — this CI is the code quality gate that protects `main`. --- > **Layout note** — the workflow below assumes the canonical scaffold, where the app > lives in `website/`. On a repo with the app at the root, drop the `defaults.run.working-directory` > block and change `cache-dependency-path` to `package-lock.json`. Check before you write: > `ls website/package.json 2>/dev/null || echo "app is at the repo root"`. ## Step 1 — Check what already exists ```bash ls .github/workflows/ 2>/dev/null || echo "No workflows yet" ``` If a CI file exists, read it before making changes. Don't overwrite working configuration. --- ## Step 2 — Create the workflow Write `.github/workflows/ci.yml`: ```yaml name: CI on: push: branches: [main] pull_request: branches: [main] jobs: quality: name: Lint, type-check, test, build runs-on: ub
