insert_middleware_position

🔀 Inserting Middleware at a Specific Position​

By default, config.middleware.use appends your middleware to the end of the stack. You can precisely control ordering with insert_before or insert_after. This helps when you need your middleware to run at a specific stage (e.g., before routing or response compression).

# config/application.rb
module YourApp
  class Application < Rails::Application
    # Insert before Rack::Runtime to run early
    config.middleware.insert_before Rack::Runtime, MyCustomMiddleware

    # Or insert after ActionDispatch::Static to modify responses
    config.middleware.insert_after ActionDispatch::Static, MyCustomMiddleware
  end
end
