Leveraging a GitHub App in various use cases

GitHub Apps allow for the creation of custom workflows tailored to specific organizational needs. By leveraging the GitHub API, these Apps can automate manual processes, such as creating release notes, updating documentation, or managing pull request lifecycles. This level of automation improves efficiency, reduces human error, and ensures consistent practices across repositories.

We’re going to look at a use case that leverages some of the work we did in a previous chapter. If you recall, we created a workflow in our scratchpad repository called Lint JavaScript Code, which ran an action we found online. The idea is that any code in there that doesn’t meet the quality of the linter will fail. There was also an option to have it possibly correct the failures by creating another commit.

We want to extend that now to have Temple Guards providing the update and the lint.

First, we’re going to leverage an action...
