From Rails to Lucky (Guide)

#lucky

Controllers and routing

In Rails you have controllers, and controllers have actions. In Lucky, we just have “Actions.” Another different is that Lucky handles routing in the action instead of in a different routes file

What’s different?

• Instead of a controller class with methods for actions, Lucky just has “actions” that are single classes. E.g. (UsersController#index in Rails is Users::Index in Lucky)
• Lucky defines routes in the action, not in a separate routes file

First things first

• If you want to follow along, install Lucky
• Learn some Crystal from the official docs if you’re not already familiar

You can also just read through this to see if Lucky looks interesting.
