npm-run-path enhances child process PATH searching in Node.js. It intelligently resolves node_modules/.bin directories, making executables from locally installed packages readily available within child processes spawned using child_process.spawn and similar functions. This eliminates the need for manual PATH manipulation, ensuring consistent execution environments, crucial for tools like linters, formatters, and build systems relying on project-local dependencies. It simplifies cross-platform compatibility by handling PATH manipulation correctly on Windows, macOS, and Linux.
