Fight!

Popularity

Both loglevel and morgan are popular npm packages, but morgan is more commonly used in the Node.js ecosystem. It is often used as a middleware for logging HTTP requests in Express.js applications. loglevel, on the other hand, is a lightweight logging library that is popular for client-side logging in web applications.

Functionality

morgan is specifically designed for logging HTTP requests and provides middleware that can be easily integrated into Express.js applications. It automatically logs request details such as HTTP method, URL, status code, response time, and more. loglevel, on the other hand, is a general-purpose logging library that can be used for logging messages and errors in both client-side and server-side applications.

Flexibility

morgan provides a predefined logging format for HTTP requests, but it also allows customization of the log format to suit specific needs. It is highly configurable and supports different output formats and log destinations. loglevel, on the other hand, provides a simple API for logging messages and errors, but it does not have built-in support for customizing log formats or destinations.

Integration

morgan is commonly used as middleware in Express.js applications and can be easily integrated into the request-response cycle. It automatically logs HTTP requests without requiring explicit logging statements in the code. loglevel, on the other hand, needs to be explicitly called in the code to log messages and errors. It can be integrated into various JavaScript frameworks and libraries, including React, Angular, and Node.js.

Developer Experience

morgan provides a straightforward and easy-to-use API for logging HTTP requests. It has good documentation and is well-suited for developers working with Express.js. loglevel also has a simple API, but it may require more manual setup and configuration compared to morgan. It has decent documentation but may not be as extensively documented as morgan.

Performance

morgan is designed to be lightweight and has minimal impact on the performance of Express.js applications. It logs requests efficiently without introducing significant overhead. loglevel is also lightweight, but since it is a general-purpose logging library, its performance may depend on the specific use case and the amount of logging being done.
