Every True Rubyist Builds Their Own Code Editor in Ruby!
Every self respecting Senior Software Engineer out there should build their own code editor, even if just as a toy app to later be discarded in favor of another code editor (though they might grow to prefer their own).

If you think of yourself as a Ruby Senior Software Engineer, but cannot build your own code editor in Ruby, there are serious holes in your skillset!!

Why I’m sticking with Rails, at least for now.
This is my journey with two leading web development frameworks: Rails and Elixir. Having invested years in Rails, I ventured into Elixir, captivated by its claims of high performance, resilience, and distributed systems. I admired Elixir and its Phoenix framework but encountered complexities when revisiting past code. On returning to Rails, I experienced greater intuitiveness and efficiency, especially with the innovative Hotwire design. Despite the unique advantages of Elixir, such as its Ecto library for complex queries, I felt more aligned and efficient with Rails. Ultimately, I decided to rewrite my Elixir-based project, Rauversion, in Rails, completing 90% in just two weeks, and I’ve had the opportunity to contrast the strengths and weaknesses of both ecosystems.

Maquina, the engine for Rails
Building apps over time, I found some work that needs to be done on every application: Authentication, Authorization, Mailers, etc. I started extracting this standard functionality into a Rails engine a few years ago. Later, tailwindscss, hotwire, stimulus, and phlex entered the picture, so I started the engine again with reusable UI patterns that take advantage of these tools. This is how Maquina was born. https://mariochavez.io/desarrollo/2023/08/08/maquina-the-engine-for-rails/
