Building a Non-Blocking Multi-Processes Web Server - Node JS Fork Example

Learn to build a non-blocking multi-process web server using Node.js fork functionality in this 23-minute tutorial. Discover how to handle expensive processing requests without blocking other incoming requests by spinning off separate processes. Explore the implementation of an 'isPrime' web service, testing with various prime numbers to demonstrate processing times. Examine both blocking and non-blocking approaches, comparing their pros and cons. Gain insights into utilizing multi-core CPUs, de-coupling processes, and managing the increased complexity of multi-process applications. Follow along with provided source code examples and learn about query parameters, debugging challenges, and health checking between processes. Master techniques to create efficient, scalable web servers capable of handling computationally intensive tasks.
