Today, was spent on refactoring my code and removing a lot of duplication and technical debt and writing a shit load of automated tests. Elixir and Phoenix make writing tests very straight forward. There isn’t a lot of stuff to setup.
- Write lots of automated tests, and have a CI run them. I did a post about setting up Elixir with circleci a while ago This has been such a life saver.
- Don’t worry too much about duplication early on in the project. This is something which Sandi Metz talks a lot about. If you come up with the wrong abstraction early on. You’ll only dig yourself deeper into the mess.
- Use tools to make your job easier. Elixir and Erlang have the awesome dialyzer which analyzes your code and catches a lot of your bugs early on.
- I started a blog called http://elixir.goodcode.in to share the interesting tidbits of elixir stuff. It already has a useful post: How to run a chunk of code when your Elixir/Phoenix app starts
- Dailyzer: https://github.com/jeremyjh/dialyxir
- Sandi Metz Blog Post about The Wrong Abstraction
- How to run stuff at startup the proper way in Elixir? Blogged about it above.
- How to run dialyzer automatically in a CI on every push? Haven’t figured this one out yet.
P.S: I’d love to hear your feedback on sprymesh which is a simple web host (backed by Dropbox Synchronization) that I am building!
