CI/CD Pipelines

GitHub Actions Workflow

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

concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
  cancel-in-progress: true

jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 22
          cache: npm
      - run: npm ci
      - run: npm run lint
      - run: npm run typecheck

  test:
    runs-on: ubuntu-latest
    needs: lint
    services:
      postgres:
        image: postgres:16
        env:
          POSTGRES_DB: test
          POSTGRES_USER: test
          POSTGRES_PASSWORD: test
        ports: ["5432:5432"]
        options: >-
          --health-cmd pg_isready
          --health-interval 10s
          --health-timeout 5s
          --health-retries 5
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 22
          cache: npm
      - run: npm ci
      - run: npm test -- --coverage
        env:
          DATABASE_URL: postgres://test:test@localhost:5432/test
      - uses: codecov/codecov-action@v4

  deploy:
    runs-on: ubuntu-latest
    needs: test
    if: github.ref == 'refs/heads/main'
    environment: production
    steps:
      - uses: actions/checkout@v4
      - run: ./scripts/deploy.sh

Use concurrency to cancel stale runs. Use needs to define job dependencies.

Reusable GitHub Action

# .github/actions/setup/action.yml
name: Setup
description: Install dependencies and cache
inputs:
  node-version:
    default: "22"
runs:
  using: composite
  steps:
    - uses: actions/setup-node@v4
      with:
        node-version: ${{ inputs.node-version }}
        cache: npm
    - run: npm ci
      shell: bash

# Usage in workflow
steps:
  - uses: actions/checkout@v4
  - uses: ./.github/actions/setup
  - run: npm test

Matrix Strategy

test:
  strategy:
    fail-fast: false
    matrix:
      node: [20, 22]
      os: [ubuntu-latest, macos-latest]
  runs-on: ${{ matrix.os }}
  steps:
    - uses: actions/checkout@v4
    - uses: actions/setup-node@v4
      with:
        node-version: ${{ matrix.node }}
    - run: npm ci && npm test

Anti-Patterns

• Not caching dependencies (npm, pip, cargo) between runs
• Running all jobs sequentially when lint and test can parallelize
• Storing secrets in workflow files instead of repository/environment secrets
• Missing concurrency groups causing redundant CI runs on rapid pushes
• Not using fail-fast: false in matrix builds (one failure cancels others)
• Deploying without an approval gate or environment protection rule

Checklist

• Dependencies cached between CI runs
• Concurrency groups cancel stale pipeline runs
• Lint, typecheck, and test run as separate parallelizable jobs
• Database services use health checks before tests start
• Coverage reports uploaded and tracked
• Deploy job requires approval for production
• Reusable actions/templates extract common setup steps
• Secrets stored in CI platform, never in code
