CI/CD Pipeline Design

Standard Pipeline Stages

# .github/workflows/ci.yml

name: CI Pipeline

on:
  pull_request:
    branches: [main]
  push:
    branches: [main]

jobs:
  # Stage 1: Code Quality
  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
      - run: npm ci
      - run: npm run lint
      - run: npm run format:check
      - run: npm run type-check

  # Stage 2: Security
  security:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - run: npm audit --audit-level=high
      - uses: snyk/actions/node@master
        env:
          SNYK_TOKEN: ${{ secrets.SNYK_TOKEN }}

  # Stage 3: Testing
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
      - run: npm ci
      - run: npm test -- --coverage
      - uses: codecov/codecov-action@v3

  # Stage 4: Build
  build:
    runs-on: ubuntu-latest
    needs: [lint, security, test]
    steps:
      - uses: actions/checkout@v4
      - run: npm ci
      - run: npm run build
      - uses: actions/upload-artifact@v4
        with:
          name: build
          path: dist/

  # Stage 5: Deploy (on main only)
  deploy:
    runs-on: ubuntu-latest
    needs: [build]
    if: github.ref == 'refs/heads/main'
    steps:
      - uses: actions/download-artifact@v4
      - run: ./deploy.sh
        env:
          VERCEL_TOKEN: ${{ secrets.VERCEL_TOKEN }}
