We also learn the benefits they found of using Elixir in a microservices architecture, the benefits they got from Broadway and much more!

I run my tests a lot when I’m working, and nothing bums me out more when I’m running my tests so frequently than long compile times before I can even run my tests. One of the unfortunate issues with absinthe is that it’s a very macro-heavy library, and as such it effectively touches every file in your application, meaning that you need to recompile a ton of files if you’re using it. But there may be ways we can avoid such long incremental compile times!

After the initial setup of my learning project, I wanted to my preferred CSS framework Tailwind to the project. Again I learned a lot about the anatomy of a Phoenix project and discovered, that the contents of the assets folder are actually a JavaScript subproject.
