GitHub Action for Lighthouse Auditing

This action integrates Google's helpful Lighthouse audits for webpages — specifically testing for Performance, Accessibility, Best Practices, SEO, and Progressive Web Apps. Right now, the action will print the five scores (out of 100) to the output and upload HTML and JSON versions of the report as artifacts. In the next release, the action will let you specify thresholds for each test and optionally fail this step if they are not met.

Inspired by GoogleChromeLabs/lighthousebot.

Usage

workflow.yml Example

The following workflow runs a Lighthouse audit on https://jarv.is/, shows the five scores in the output of the step, and uploads the .html and .json results as artifacts to download (as shown above).

name: Audit live site
on: push

jobs:
  audit:
    runs-on: ubuntu-latest
    steps:
    - name: Audit live URL
      uses: jakejarvis/lighthouse-action@master
      with:
        url: 'https://jarv.is/'
    - name: Upload results as an artifact
      uses: actions/upload-artifact@master
      with:
        name: report
        path: './report'

Pull Request Audits with Netlify Deploy Preview

This GitHub action integrates with Netlify's Deploy Preview feature, allowing you to test PRs before accepting them. To enable, you need to pass in your Netlify site's URL (on the Netlify subdomain — also called your "site name" in the Netlify dashboard — not your custom domain) to the netlify_site input variable:

name: Audit pull request
on: pull_request

jobs:
  audit:
    runs-on: ubuntu-latest
    steps:
    - name: Audit Netlify deploy preview
      uses: jakejarvis/lighthouse-action@master
      with:
        netlify_site: 'blissful-heisenberg-16c40f.netlify.com'
    - uses: actions/upload-artifact@master
      with:
        name: report
        path: './report'

On pull requests, the PR number will be extracted from the GitHub event data and used to generate the deploy preview URL as follows: https://deploy-preview-[[PR_NUMBER]]--[[NETLIFY_SITE]].netlify.com. You can combine the two above examples and include both url and netlify_site and run on on: [push, pull_request] and the appropriate URL will be automatically selected depending on the type of event.

To-Do

• Make CI fail if scores do not meet specified thresholds.
• Ability to customize flags passed to both Chrome and Lighthouse
• Batch URL testing
