serialize-error provides a simple and reliable way to serialize an error object in JavaScript, making it suitable for transferring errors, such as between a client and server. It captures error properties beyond the standard message and stack trace, including custom properties, ensuring comprehensive error information is preserved. The package avoids circular references during serialization, preventing common issues when stringifying complex error structures. This is especially helpful for logging and debugging application issues.
The serialize-error package has had sporadic releases since its initial version in October 2015. Releases occurred roughly every few months in the early years, becoming less frequent after 2021. The last release was version 12.0.0 in January 2025. There were releases for the months August and November in 2023, and then a longer gap until January 2025.
Serialize-error npm package downloads show a consistently upward trend, from 25.9 million in March 2024 to 42.6 million in August 2025. September 2025's partial data indicates a potentially significant increase, with 5.3 million downloads so far, suggesting continued growth.
