Morgan: One-Line Request Logging for Express

Morgan is a plug-and-play stenographer for your Express app, automatically logging every incoming HTTP request to a stream. It's a specialized tool for HTTP traffic visibility. Use predefined formats for quick debugging or the `skip` option to log only errors in production. The `immediate` option logs on request arrival, capturing traffic even if the server crashes, but this prevents logging response data like the final status code or response time.
