I’m building a side project in Phoenix right now. For me the learning curve is wondering whether Phoenix has a built-in or “everybody does it this way” solution to the problem I’m facing or whether it’s something I should implement myself.

In Rails the answer is always “use this popular gem” and in Go the answer is always “roll your own”. Phoenix is somewhere in the middle.

The good thing about Phoenix is you are not forced to go in any particular convention for everything, you can craft them yourselves from scratch. The bright side of this is you will only every little thing in the implementation and you'll know how to optimize it.

The one time I really want to override something in a Phoenix app was deleting a response header bolted on by Cowboy (I think it was the server header). I couldn't find a work around, so I did something lame like intercept the formatted response and modify it. Some flexibility in that area would have been nice, but it was a pretty niche corner case on a not too important app, so a time crunch hack was my best option.
