Introduction to GitHub Actions
summary
GitHub Actions now provides hosted CI/CD runners for Linux, Windows and macOS and lets repositories trigger workflows on events, run matrix builds (demo runs on matrix runs on Node 8/10/12), and catch regressions — a malformed change (a++ + b) breaks tests and Actions flags the failing unit tests. Workflows use YAML, reusable Actions (example: azure/webapps-deploy) and GITHUB_TOKEN/secrets to deploy to Azure, publish Docker images to GitHub Packages, and connect with security tooling so fixes can be opened automatically by Dependabot (integrates with GitHub Packages and Dependabot). It even runs device UI tests on hosted Macs (macOS runners run iOS UI simulators).
