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.
Can I add authentication to my API?
Yes, you can use gems like Devise or JWT for authentication. They provide methods to secure your API endpoints.
