hello-world-javascript-action VS typescript-action

If you are new, there's also a simpler introduction in the Hello world JavaScript action repository.

To get started quickly with a JavaScript action, I recommend using the official templates from GitHub for JavaScript and TypeScript.

While learning about GitHub Actions, I came across the GitHub Actions Org, and they have a bunch of templates for building custom GitHub actions. So, I started searching for a template that has TypeScript support, ensuring type safety to write bug-free code. I found the typescript-action template that includes support for tests, linter, versioning, and more.

This is the template I used for my TypeScript action https://github.com/actions/typescript-action

I found the GitHub actions documentation easier to read than Azure, so I would recommend starting writing and testing your extensions on GitHub by using the official template actions/typescript-action. The mentioned template provides a good starting point; I won't repeat the steps here. Play with it, write some simple stuff, and then return here for the next steps.

GitHub maintain a set of repos called actions. One of which is called cache.

On the TypeScript side, setup was much easier. There was already a template from GitHub that took care of the basics. Most of the time spent here was updating dependencies and getting my editor to play nicely with it—18 minutes, about 10% of the total.

Now that you know how to create your own GitHub Actions, why not give it a try? Head to the GitHub Marketplace and start exploring the existing Actions, or create your own and share it with the community. With GitHub Actions, the possibilities are endless, so start building and see what you can accomplish

Your build most likely fails because your tests fail. Most CI pipelines today, like Jenkins, Circleci, GitLab, TeamCity, Bamboo, and GitHub Actions, are configured to automatically cause the build process to fail when tests fail.
