Hi,
can you indicate which OS platform you are using for your demo’s. including Erlang/Elixir/Phoenix/Nodejs versions. I have tried building on ubuntu 16.04 (and windows 7) and run into issues just compiling. (don’t know much about nodejs but ok with elixir/erlang etc).
cheers

PS how about a complete mix project with all dependecies etc for the test system?
