- Logrus is a popular logging library for Go applications, but due to performance and lack of active maintenance, it's time to look for alternatives.
- Zerolog is an excellent alternative to Logrus as it is one of the fastest logging libraries for Go, offering easy integration and zero-allocation logging.
- Zerolog is not only powerful but also easy to use and highly extensible, making it a promising option for developers looking to improve their logging experience.
Logrus has been a popular choice for logging in Go applications for a long time, but as the logging library landscape continues to evolve, it's time to reconsider its place in your projects. In this post, I will list several reasons why you should stop using Logrus and introduce better alternatives that can enhance your logging experience.
Performance is Poor
One of the primary reasons I moved away from Logrus is its performance. While it offers a plethora of features, the overhead it introduces can be substantial, especially in high-throughput applications.
Logrus generates new maps for each logging operation, which is extremely bad in terms of performance. This is something that should never be done, and in fact, a single logging library can seriously degrade application performance.
Lack of Active Maintenance
Another significant drawback of Logrus is that it's not actively maintained. While it has been a popular choice for logging in Go applications, the pace of development has slowed down, raising concerns about its long-term viability.
What should I use instead?
If you're considering moving away from Logrus, I highly recommend using Zerolog. It stands out as one of the fastest logging libraries in Go, making it an excellent choice for performance-conscious developers.
Zerolog boasts a very ergonomic API design, enabling easy integration into your applications without the complexity often associated with logging libraries. Its straightforward syntax makes implementing structured logging simple, allowing you to log rich, contextual information effortlessly.
One of the standout features of Zerolog is its zero-allocation logging. This means it doesn't allocate any memory during logging operations on hot paths, which is crucial for high-performance applications. By reducing the pressure on the garbage collector, Zerolog helps maintain the responsiveness of your application even under heavy logging loads.
It's not only performant but also very easy to use and highly extensible, enabling you to tailor it to your specific logging needs.
