The GitHub Actions CI workflow I copy into every Node project

GitHub Actions serves as built-in automation that executes workflows based on specific events. For Node.js projects, a standardized CI workflow saved as .github/workflows/ci.yml ensures consistency. This configuration triggers on push to main or pull requests, utilizing ubuntu-latest and node-version 20. The process includes actions/checkout@v4 and actions/setup-node@v4 with npm caching. It sequentially executes npm ci, lint, test, and build commands, while concurrency settings cancel in-progress runs to optimize resource usage.
