Copy# Pattern 1: Standard workflow with best practices
name: CI
on:
  push:
    branches: [main]
    paths: ['src/**', '.github/workflows/*.yml']
  pull_request:
    branches: [main]

permissions:
  contents: read
  packages: write

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      
      - name: Cache dependencies
        uses: actions/cache@v4
        with:
          path: ~/.npm
          key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
      
      - name: Build
        run: npm ci && npm run build

# Pattern 2: Docker multi-arch build
  docker:
    needs: build
    runs-on: ubuntu-latest
    steps:
      - uses: docker/setup-buildx-action@v3
      - uses: docker/build-push-action@v5
        with:
          platforms: linux/amd64,linux/arm64
          cache-from: type=gha
          cache-to: type=gha,mode=max

# Pattern 3: Matrix testing
  test:
    strategy:
      fail-fast: true
      matrix:
        node: [18, 20]
    steps:
