Example Usage

In the below example we run Lighthouse on two URLs, log scores, save the HTML reports as artifacts, upload reports to AWS S3, notify via Slack with details about the change from Git data. By specifying the pull_request trigger and accessToken - we allow automatic comments of audits on the corresponding PR from the token user.

name: Test Lighthouse Check
on: [pull_request]

jobs:
  lighthouse-check:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@master
      - run: mkdir /tmp/artifacts
      - name: Run Lighthouse
        uses: foo-software/lighthouse-check-action@master
        with:
          accessToken: ${{ secrets.LIGHTHOUSE_CHECK_GITHUB_ACCESS_TOKEN }}
          author: ${{ github.actor }}
          awsAccessKeyId: ${{ secrets.LIGHTHOUSE_CHECK_AWS_ACCESS_KEY_ID }}
          awsBucket: ${{ secrets.LIGHTHOUSE_CHECK_AWS_BUCKET }}
          awsRegion: ${{ secrets.LIGHTHOUSE_CHECK_AWS_REGION }}
          awsSecretAccessKey: ${{ secrets.LIGHTHOUSE_CHECK_AWS_SECRET_ACCESS_KEY }}
          branch: ${{ github.ref }}
          outputDirectory: /tmp/artifacts
          urls: 'https://www.foo.software,https://www.foo.software/contact'
          sha: ${{ github.sha }}
          slackWebhookUrl: ${{ secrets.LIGHTHOUSE_CHECK_WEBHOOK_URL }}
      - name: Upload artifacts
        uses: actions/upload-artifact@master
        with:
          name: Lighthouse reports
          path: /tmp/artifacts

Example Usage: Failing Workflows by Enforcing Minimum Scores

We can expand on the example above by optionally failing a workflow if minimum scores aren't met. We do this using foo-software/lighthouse-check-status-action.

name: Test Lighthouse Check with Minimum Score Enforcement
on: [push]

jobs:
  lighthouse-check:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@master
      - run: npm install
      - name: Run Lighthouse
        uses: foo-software/lighthouse-check-action@master
        id: lighthouseCheck
        with:
          urls: 'https://www.foo.software,https://www.foo.software/contact'
          # ... all your other inputs
      - name: Handle Lighthouse Check results
        uses: foo-software/lighthouse-check-status-action
        with:
          lighthouseCheckResults: ${{ steps.lighthouseCheck.outputs.lighthouseCheckResults }}
          minAccessibilityScore: "90"
          minBestPracticesScore: "50"
          minPerformanceScore: "50"
          minProgressiveWebAppScore: "50"
          minSeoScore: "50"
