Both log4js and roarr are popular logging libraries in the Node.js ecosystem. However, log4js has been around for longer and has a larger user base and community support.


log4js offers a wide range of features and configuration options for logging, including different log levels, log formatting, and appenders for various output targets such as console, file, and database. roarr, on the other hand, focuses on providing a minimal and performant logging solution with a simplified API.


log4js provides more flexibility in terms of customization and configuration due to its extensive feature set. It allows you to configure loggers, appenders, and layouts according to your specific needs. roarr, being a minimal logging library, offers less flexibility but keeps the API simple and easy to use.


roarr is known for its excellent performance due to its minimalistic design and emphasis on speed. It is optimized for low overhead and provides efficient logging in high-performance environments. log4js, while still performant, may have slightly more overhead due to its feature-rich nature.

Community and Support

Both log4js and roarr have active communities and receive regular updates. However, log4js benefits from a larger user base and more extensive community support, which translates into more resources, tutorials, and examples available online. roarr has a smaller community but still provides sufficient support.

Integration and Compatibility

log4js offers extensive integration options and compatibility with various frameworks and tools, including Express, Winston, and log4j (for Java applications). roarr, though less feature-rich, can be easily integrated into any Node.js project without dependencies on other libraries.
