# CI Pipeline Patterns ## GitHub Actions Workflow Template ```yaml name: CI on: push: branches: [main] pull_request: branches: [main] concurrency: group: ${{ github.workflow }}-${{ github.ref }} cancel-in-progress: true jobs: lint-and-type: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - uses: actions/setup-node@v4 with: { node-version: 20, cache: npm } - run: npm ci - run: npm run lint - run: npm run type-check test: runs-on: ubuntu-latest strategy: matrix: shard: [1, 2, 3, 4] steps: - uses: actions/checkout@v4 - uses: actions/setup-node@v4 with: { node-version: 20, cache: npm } - run: npm ci - run: npm test -- --shard=${{ matrix.shard }}/4 build: needs: [lint-and-type, test] runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - uses: actions/setup-node@v4 with: { node-version: 20, cache: npm } - run: npm ci - run: npm run build - uses: actions/upload-artifact@v4 with: { name: build, path: dist/ } ``` ## Caching Strategies ```yaml # npm cache - uses: actions/cache@v4 with: path: ~/.npm key: npm-${{ hashFiles('**/package-lock.json') }} # Docker layer cache - uses: docker/build-push-action@v5 with: cache-from: type=gha cache-to: type=gha,mode=max # Turborepo remote cache - run: npx turbo build --cache-dir=.turbo ``` ## Monorepo CI (Affected Only) ...
