How do I create a RESTful API using Ruby on Rails?

To create a RESTful API in Ruby on Rails, start by generating a new Rails application with the command rails new my_api --api. This sets up a lightweight version of Rails optimized for API-only applications.

What are the key components I need to set up?

You'll need to set up routes, controllers, and models. Define your routes in config/routes.rb, create controllers for handling requests, and set up models for your data.

How do I handle JSON responses?

In your controllers, use render json: @resource to send JSON responses. Make sure to serialize your data properly for the API.
