A lightweight serverside Elixir framework like this is exactly what I was looking for earlier this week. Phoenix is really clunky in my opinion and pretty foreign (Ruby/Rails-like) coming from a lightweight Flask/Express/Go background.
Ouch, this is not a server library but a client! We updated the title of the blog post since it wasn't clear, not sure if we can update it here as well :\ Sorry for the confusion!
Phoenix is just some additional libraries around Plug. The reason it’s so popular is that there’s almost no performance hit compared to using raw plug unlike a lot of other frameworks.
