Supersonic, Subatomic GitHub

Track: Unobtanium
You've seen GitHub Actions, but did you know about GitHub Apps? "GitHub Apps are tools that extend GitHub's functionality." A GitHub app lets you interact with GitHub -- or a third party system, or both! -- when certain things happen in a repository. Things like someone pushing to the repository, creating a pull request or issue, commenting on or editing pull requests, issues, etc. The official docs show you how to write an App using JavaScript, which is fine, but then you have to use JavaScript! In this presentation, we'll look at how we can use our Java and Quarkus experience to write an application. We'll register the application with GitHub, set up the project for the application, and react to various events. At the end, we'll have a working GitHub application, written in Java (or Kotlin!) that is supersonic, subatomic awesomeness.
