Fight!

Popularity

Both loglevel and pino are popular logging libraries in the JavaScript ecosystem. However, pino has gained significant popularity in recent years due to its high performance and scalability.

Size

Loglevel is a lightweight logging library with a small file size, making it ideal for projects that prioritize minimal overhead. Pino is also lightweight and designed for high performance, but it offers additional advanced features that may slightly increase its file size.

Performance

Pino is known for its exceptional performance, especially in high-throughput scenarios, due to its asynchronous and highly optimized architecture. Loglevel, while still performant, may not be as optimized for high-performance use cases as pino.

Features and Flexibility

Loglevel is a simple and straightforward logging library that provides essential logging capabilities, such as log levels and customizable output. Pino, on the other hand, offers a rich set of features including log levels, structured logging, log formatting, log redaction, stream support, and integrations with various frameworks and tools. Pino provides more flexibility and can handle complex logging scenarios.

Developer Experience

Both loglevel and pino have user-friendly APIs and are easy to set up and use. Loglevel has a basic API and is suitable for simpler logging needs. Pino, while more powerful, has a more comprehensive API and may require a slightly steeper learning curve for beginners.

Integration and Community Support

Both loglevel and pino have active communities and are well-maintained. However, pino has gained widespread adoption and has strong community support, with many integrations and extensive documentation available. Pino is also well-suited for integration with existing logging and monitoring tools and frameworks.
