AI BriefingAutomating Web Performance Measurement with Lighthouse CI and GitHub Actions
Key point
This guide introduces how to integrate Lighthouse CI with GitHub Actions to automatically measure performance on code pushes and display detailed metrics like FCP and LCP with color coding in PR comments.
Details
Integrating Lighthouse CI with GitHub Actions enables automatic performance measurement upon code pushes. By configuring the assert option in lighthouserc.js, you can trigger a warning if the Performance score is below 90 and an error if the Accessibility score is below 100, preventing build failures. Additionally, by adding a script to parse the manifest.json of the generated report, you can display detailed metrics such as FCP and LCP with color codes in PR comments, allowing you to identify and resolve performance regressions proactively.
