GenServer call?

First some context, I have an app running on ruby on rails, and I would like to move business logic to an elixir application (reports on pdf or html and some charts, basically).

I would like to know if it is possible to make a GenServer call from ruby? If so, were can I find examples? Or, if it is not possible how can I make the two apps communicate one each other?

One approach it’s to make a phoenix app could that receive some requests and then response them with some json, html or pdf. But I want to avoid this approach if it is possible.

Maybe ErlPorts might help you? There’s also a wrapper for them in elixir.

I’ve also found a blogpost from the author of the wrapper.
