Morgan
Morgan is a popular HTTP request logger middleware for Node.js applications, commonly used with the Express framework. It logs details about incoming HTTP requests, such as the method, URL, status code, response time, and user agent, to help developers monitor and debug server activity. It outputs logs in various pre-defined or custom formats, making it easy to track application traffic and performance.
Developers should use Morgan when building Node.js web servers, especially with Express, to gain visibility into request handling and identify issues like slow endpoints or errors. It is essential for debugging in development environments and can be configured for production logging to analyze traffic patterns and security incidents. Use cases include monitoring API usage, troubleshooting server errors, and auditing request flows in web applications.
