DEV Tutorial: Build a Parallel CI Pipeline with Lint, SonarQube, and Trivy
A weekend homework assignment from DEV Community guides students through setting up a three-job GitHub Actions CI pipeline for a restaurant company project. The exercise covers running Trivy filesystem vulnerability scans, including development dependencies, and understanding how CVEs and severity levels apply to real codebases. Students are also asked to trace transitive dependency chains — specifically how nanoid enters the project through Vite and PostCSS — and document their findings in a structured vulnerability report. The pipeline requires three independent parallel jobs triggered on pull requests to the main branch, teaching students why parallelism speeds up CI workflows. The assignment concludes with a push to GitHub, pull request creation, and live verification of all three jobs running simultaneously in GitHub Actions.
