sonic-boom is a fast, asynchronous file logger for Node.js. It optimizes performance by buffering writes and using fs.write directly, minimizing context switches to the kernel. This makes it ideal for high-throughput logging scenarios. Unlike traditional logging libraries, sonic-boom focuses purely on efficient file writing, allowing developers to integrate it seamlessly into existing logging solutions or frameworks. It is configurable, supporting file rotation based on size or time, and offers options for synchronous or asynchronous writes.
