Both Bunyan and Signale are popular npm packages for logging in JavaScript. However, Bunyan has been around for longer and has a larger user base and community support. Signale, while relatively newer, has also gained popularity and has a growing community.

Logging Features

Bunyan provides a highly customizable and extensible logging experience. It supports structured logging, allows for logging of custom levels, and allows the use of log serializers. Signale, on the other hand, focuses on providing a colorful and eye-catching logging experience out of the box. It offers various log levels, custom styling, and supports log grouping and emoji icons.


Bunyan provides a straightforward configuration process, allowing developers to define various options like log level, output streams, serializers, and more. Signale also allows for configuration but is more opinionated with a focus on simplicity and ease of use. Both packages support configuration via code or configuration files.


Bunyan offers extensive customization options and flexibility, making it suitable for complex logging scenarios. It allows for custom log formats, multiple output streams, and the ability to write custom log serializers. Signale, while less customizable, provides a set of predefined log styles and colors that can be extended or modified to suit specific needs.


Both Bunyan and Signale can be easily integrated into existing projects. However, Bunyan is more commonly used in backend and server-side applications, while Signale is often used in frontend and client-side applications, including with popular frameworks like React and Vue.

Developer Experience

Bunyan offers a rich set of APIs and utilities for effective logging, but its documentation can be perceived as more complex due to its advanced features. Signale, with its simpler and more intuitive API, provides a shorter learning curve and has well-documented examples and guides.

Community Support

Both Bunyan and Signale have active communities and are actively maintained. Bunyan has a mature and established community, while Signale, being a newer package, has a smaller but growing community. Both packages have regular updates and bug fixes.
