🚀 Automated Lighthouse metrics to your PR with Vercel and Github Actions.

The complete action can be found in Lighthouse-github-action/.github/workflows/

Action workflow

1. Get the preview url for the PR (from Vercel).
2. Run a Lighthouse audit on the preview url.
3. Format the score to a table (+throw in a few emojis).
4. Post a comment on the PR with the formatted score.

Integrations used:

• treosh/lighthouse-ci-action
• sticky-pull-request-comment
• vercel-preview-url-action

Limitations:

• Always runs the Lighthouse audit on the root page.

Potential future improvements:

• Combine the action with a budget to prevent PRs that bring the metrics below a set treshhold.
• Run the audit only on the pages affected by the PR.
• Compare the collected metrics with the actual metrics of your production site.
