How to Fix Dialyzer Errors
If you have six errors in a single file, it's probably best to scroll up to the top of that list and fix the first one. And then the other five could just disappear afterwards. The easiest way is at least when running dialyzer slash dialyzer, it will order the warnings. Some of these errors can be super cryptic and they can be very challenging to even figure out like what is dialyzer trying to tell me. It's no difference than adding some new piece of tech debt or maybe you write a unit test and it's failing over and over so you skip that particular test.
Dialyzer is something that eventually everyone hears about in the Elixir community. It's a static code analysis tool that has both fans and detractors, and with good reasons on both sides! We talk with Noah Betzen about how he brought Dialyzer to several mature Elixir projects. He wanted the benefits of finding and fixing bugs and to prevent new problems from being added. He shared tools, strategies and other resources for how to get started without stopping everything to fix all the existing problems. If you've ever tried to add Dialyzer to a project and aborted, then this discussion may give you the courage and the tools to try again!
