Espresso Framework is a framework for Ruby. Its aim is Scalable, Speed and Simplicity. I am not personally familiar with Ruby, but the author claims that in Espresso:
- Actions are regular Ruby methods
- Path params are accessed via arguments
- Controllers are regular Ruby classes
- Slices are regular Ruby modules
As with all framework, it was designed to fit the designer’s need. So, I suggest you head over to Espresso Framework website over at Github to learn more about it.
