GitHub Actions CI/CD

Summary

GitHub Actions is GitHub's native CI/CD platform for automating software workflows. Define workflows in YAML files to build, test, and deploy code directly from your repository with event-driven automation.

When to Use

• Automate testing on every pull request
• Build and deploy applications on merge to main
• Schedule regular tasks (nightly builds, backups)
• Publish packages to registries (npm, PyPI, Docker Hub)
• Run security scans and code quality checks
• Automate release processes and changelog generation
