My journey from Ruby to Elixir: lessons learned ✍️
Why I Looked Beyond Ruby
For years, Ruby was my go-to language for building everything from small prototypes to full-fledged production apps. I fell in love with its elegance and expressiveness and how Ruby on Rails could turn an idea into a working web app in record time. The community—with its focus on kindness and collaboration—only deepened my appreciation. In short, Ruby felt like home.
But as my projects grew in complexity, I started running into bottlenecks. I had apps requiring real-time features, massive concurrency, and high availability. Scaling them with Ruby often meant juggling multiple processes, external services, or creative threading approaches—all of which worked but never felt truly seamless. That’s when I stumbled upon Elixir.
At first glance, Elixir’s syntax reminded me of Ruby. It looked approachable and developer-friendly. But beneath the surface lies a fundamentally different philosophy, heavily influenced by Erlang’s functional model and the concurrency power of the BEAM. Moving from Ruby’s object-oriented approach to Elixir’s functional core was eye-opening. Here’s how I made that transition and why I think it’s worth considering if you’re a fellow Rubyist.
