Fix Lighthouse example
Opened this issue · 3 comments
The Lighthouse example in the README could be improved:
- the npm install and build steps are unnecessary (other than the global install of
lchi/cli
), since we are testing against Netlify - if using the Lighthouse CI Github App to get Github Status Checks fed back to the PR, the checkout step needs to get its ref from
github.event.pull_request.head.sha
and the final step needs to get theLHCI_GITHUB_APP_TOKEN
from the repo's secrets and supply it toenv
.

Thanks for the feedback @lunelson ! I definitely agree about the install steps.
I'm sort of confused about this part:
with:
ref: ${{ github.event.pull_request.head.sha }}
Won't the Action re-run with the latest commit by default when the PR is updated?
@JakePartusch yeah sorry that's a Lighthouse specific fix, and I can't find the link any more to the issue thread about it, but the Lighthouse CI Github App was not picking up the reference, so the status-check update (posting the results back to the list of checks, after the netlify checks) wasn't coming through, you'd still have to dig through the action output to find the URL of the report. With this fix, it posts the status update
@JakePartusch you can find the fix here GoogleChrome/lighthouse-ci#172
