CI Pipeline Fundamentals
Build a working continuous integration pipeline from a blank repo — triggers, jobs, dependency caching, and status checks — using GitHub Actions.
Prerequisites: a GitHub account and repo, basic command-line git, any small Node.js or Python project to build against.
Sourcing & version notes: verified against current GitHub Actions docs as of July 2026 — actions/checkout@v7 and actions/setup-node@v6 are the current majors. Node 20 runners were deprecated June 16, 2026 in favor of Node 24, so examples pin Node 22 (Active LTS). Re-check action majors if this sits before publishing — they bump every few months.
Continuous Integration means every push and pull request automatically triggers a build-and-test run, so problems surface in minutes instead of at merge time or in production. This project builds that loop end to end: a workflow file that checks out code, installs dependencies, runs tests, and reports pass/fail back to the pull request — the pattern every other CI/CD project in this roadmap builds on.
