custom_request_logger_middleware

🔍 Log Request Details

Creating a custom middleware allows you to capture and log request metadata before Rails even hits your controllers. This can be invaluable for performance monitoring or security auditing. Place your middleware in app/middleware and then hook it into the stack.

# app/middleware/request_logger.rb
class RequestLogger
  def initialize(app)
    @app = app
  end

  def call(env)
    start_time = Process.clock_gettime(Process::CLOCK_MONOTONIC)
    status, headers, response = @app.call(env)
    duration = ((Process.clock_gettime(Process::CLOCK_MONOTONIC) - start_time) * 1000).round(2)
    Rails.logger.info "[RequestLogger] #{env['REQUEST_METHOD']} #{env['PATH_INFO']} completed in #{duration}ms with status #{status}"
    [status, headers, response]
  end
end

# config/application.rb
module MyApp
  class Application < Rails::Application
    # Insert after Rails::Rack::Logger so you still see Rails logs
    config.middleware.insert_after Rails::Rack::Logger, RequestLogger
  end
end
