thetool
A CLI tool to capture CPU, memory, coverage, and other performance profiles for Node.js apps in Chrome DevTools format.
What is thetool?
thetool is a CLI tool that captures CPU, memory, coverage, and other performance profiles from Node.js applications and outputs them in a Chrome DevTools-friendly format. It solves the problem of profiling Node.js apps in environments where Chrome DevTools cannot run directly, such as servers or headless setups, by allowing developers to capture data remotely and analyze it locally.
Node.js developers and DevOps engineers who need to profile and optimize the performance, memory usage, or code coverage of their applications, especially in server-side or CI/CD environments.
Developers choose thetool because it extends Chrome DevTools' profiling capabilities to any Node.js environment, supports child processes and workers, and offers a simple CLI with on-demand profiling, making it a versatile tool for performance analysis without requiring a browser.
