Notes for the Reviewer

New Dependency Submission

• Test Vercel preview deploy broken link checker
• Currenlty dummy waits for 3m (180s) if the Vercel deployment_status != 'READY'
  • Tried to use the dynamic https://github.com/UnlyEd/github-action-await-vercel, but it couldn't ever find the deploy for some reason. Maybe because I'm using a token from my personal account, not Checkly's 🤔
  • Our docs page almost always takes 2m20s (140s) to build though, so this should be fine
• Forked celinekurpershoek/link-checker for actually walking through all the links and testing them. That GHA worked just fine on its own, however, the output that it used to comment on this PR didn't include the broken links themselves, it would just say "found X broken links out of Y links found".. With our fork in here it also includes the broken links themselves in the comment body
  • The only change from the upstream is the multiline comment body which includes the actual broken links themselves. Found at: .github/link-checker/entrypoint.sh:63-68
  • See below for example comment output with broken links 🥳
