GitHub Actions are a powerful tool to automate your workflow. They can be used to run tests, deploy your code, publish a package, and much more.

The cool thing is, there's a GitHub Actions Marketplace where you can find a lot of actions created by... the community. But what if you can't find the action you need? You can create your own and publish it there!

During this course, we'll create an action with Typescript that will add a label to new pull requests automatically.

In this tutorial, we're going to see in detail how to:
Create a GitHub Action in Typescript
Expand our Action to support custom inputs
Integrate with GitHub's API to add labels to Pull Requests
Unit testing our action
Debugging in Visual Studio Code
Publishing our action to the GitHub Marketplace
Using our action in another repository
Some final touches to make our project more robust
