I spend a lot of my time writing GitHub Actions.Specifically, I need to script a ton of things. The current way of writing GitHub Actions with YAML is usually fine for small jobs. But for anything complicated, I often find myself in incredibly cursed shell-in-YAML situations.This was a major source of bugs for me. Since the script was written in YAML, there was actually not an easy way to modularize out the scripting logic to unit test them. Worse, there was zero type safety! For those who work with GitHub Actions frequently, you know how annoying this gets.My ideal GitHub Actions workflow would be to write actual programs, preferably in a language with strong types support.I also don t want an opinionated framework or a beefy runtime to run my GitHub Actions. I literally just want a way to write arbitrary programs that can call other services using native tooling from their respective ecosystems; for example, the AWS SDK to orchestrate my cloud.So this got me thinking about the tooling in this space, and I was really surprised to find that it wasn t that great. Outside of a few linters and the popular `act` project, there was very little support for us DevOps guys.That s why I made Hollywood! (Try to guess why it s name this way, haha. Hint at the end.)It’s fully open-source and MIT-licensed. Just import Hollywood and you can begin writing your GitHub Actions logic purely in TypeScript.Hollywood is not a framework so there are very few -- if any -- opinions as to how you ought to use it. You are free to do literally whatever you want with it, provided that it s legal in TypeScript.This means you can validate your types with Zod or you can even use your favorite TypeScript frameworks, e.g. Effect.ts.Hollywood is also very lightweight: only 53 kB and only 6 runtime deps.If you wanted to containerize your Hollywood Actions, you are also not locked into any particular opinions or preconceived notions of how you should set up your runtimes and local testing. You can use Docker, or Podman, or Lima, or Apple s `container`, or a remote cloud service. Again, it s literally just TypeScript. You can do whatever you want with it.Hollywood is a fully general-purpose TypeScript library that compiles your beautiful TypeScript into validated YAML for your GitHub Actions to consume!--Hint: Lights, cameras, _! Fun fact: you are allowed to shell out in TypeScript, so you can actually just shell out to any language you’d prefer, not just TypeScript.
