How do I configure middleware in a Rails application?

To configure middleware in a Rails application, you can modify the config/application.rb file or use the config.middleware stack.

Can you give me an example of adding a custom middleware?

Sure! You can create a custom middleware class and then add it to the middleware stack like this:

class MyCustomMiddleware
  def initialize(app)
    @app = app
  end

  def call(env)
    # Your custom logic here
    @app.call(env)
  end
end

# In config/application.rb
config.middleware.use MyCustomMiddleware

What are some common middleware used in Rails?

Common middleware in Rails includes Rack::Logger, Rack::MethodOverride, and ActionDispatch::Static. Each serves a specific purpose.

How can I check the middleware stack in my Rails app?

You can check the middleware stack by running rails middleware in your terminal. This will list all the middleware in use.
