The answer is probably no but I thought I’d try:
Is there a way to write Elixir functions that can be invoked by a Rails app as efficiently as a Ruby library? Most of my new Rails development is in the form of Ruby libs for parsing and string manipulation, used during a web apps’ request cycle. In my app, I keep requests < 100ms.
I’d much rather write all new code in Elixir, but the only way I know to call it from Rails is as a web microservice.
(As I write this, I’m thinking about how ridic fast a stateless, logic-only Elixir web microservice can be: sub-millisecond. So I ought to have time to make a call to one during a Rails server’s response. And this might be my answer.)
