Github Actions - from Zero to Hero
summary
Starts with a real problem: a team burns 99% of its Actions minutes, then cuts usage by ~75% using specific techniques. Shows GitHub Actions YAML patterns: cache node_modules and package-manager caches plus a marketplace action to store build artifacts; use matrix permutations to run OS and Node-version combinations in parallel; use concurrency cancel-in-progress to stop obsolete runs; create reusable workflows (call via workflow_call) but pin the branch/tag to avoid mismatched YAML. Includes Cypress binary caching, Docker containers for stable environments, and branch protection for required checks.
