🛠️ Custom Logging Middleware

Creating a custom logging middleware lets you capture detailed request and response information without polluting controllers. This approach is useful for auditing, custom metrics, or integrating with external logging services. Implement the call method, log before and after the downstream app, and ensure you properly forward the env and response.

# app/middleware/custom_logging_middleware.rb
class CustomLoggingMiddleware
  def initialize(app)
    @app = app
  end

  def call(env)
    start_time = Time.now
    Rails.logger.info("[CustomLogger] Started #{env['REQUEST_METHOD']} #{env['PATH_INFO']}")

    status, headers, response = @app.call(env)

    duration = ((Time.now - start_time) * 1000).round(2)
    Rails.logger.info("[CustomLogger] Completed in #{duration}ms with status #{status}")

    [status, headers, response]
  end
end

# config/application.rb
config.middleware.use CustomLoggingMiddleware
