Both Log4js and Signale are popular npm packages for logging in Node.js applications. Log4js has been around for longer and has a larger community and user base. However, Signale has gained popularity due to its simplicity and modern logging experience.


Log4js is a feature-rich logging library that supports different log levels, log rolling, file appenders, and more. It provides a flexible configuration and can be customized to fit different logging needs. Signale, on the other hand, focuses on providing a clean and customizable logging output with colorful and emoji-rich log messages.


Log4js is widely used in enterprise-level applications and frameworks. It offers more advanced logging capabilities and is suitable for complex logging scenarios. Signale, on the other hand, is more lightweight and user-friendly, making it a great choice for smaller projects or personal use.


Both packages can be easily integrated into Node.js projects. Log4js has integrations with different frameworks and libraries, allowing seamless logging in various environments. Signale is focused on providing a standalone logging solution and does not have specific integrations with other libraries.


Log4js has a more complex configuration setup, which provides fine-grained control over logging behavior. It supports different configuration files and options. Signale, on the other hand, offers a simpler configuration approach with an intuitive API for configuring loggers and setting log levels.

Developer Experience

Signale aims to provide a delightful developer experience with its clean and colorful logs, while Log4js is more traditional and offers a wider range of configuration options. Depending on personal preference and project requirements, developers can choose between a highly configurable logging solution (Log4js) or a more user-friendly and visually appealing logging experience (Signale).


Both Log4js and Signale are actively maintained by their respective communities. Log4js has a longer history and a larger contributor base, which ensures continued updates and bug fixes. Signale is also well-maintained and has a responsive community that addresses issues and provides regular updates.
