How does child process work in Node.js?

Child process in Node.js is a subprocess that can run independently of the main application flow. This allows Node.js to perform non-blocking operations, a fundamental aspect of its design. Child processes can handle tasks like computations, file operations, or any other process that would otherwise block the main thread, ensuring that the server can still […]

How worker-threads, child_process, cluster works?

Understanding how worker threads, child_process, and clusters work in Node.js is critical to developing high-performing and scalable applications. Worker threads let you offload CPU-intensive tasks to separate threads, child processes let you run external commands or run other Node.js scripts without blocking the event loop, and clusters make better use of CPU cores to handle […]
