I'm the author of the boilerplate mentioned here if people have any question about it, thanks for sharing! I've had the same struggles personally when building my web app so that's why I backported some my code into this repo, the defaults with Phoenix are great but there's a long way to make it kind of usable for real users.

Shamless plug for our Elixir boilerplate we’ve been maintaining for three years :) https://github.com/mirego/elixir-boilerplate
