The purpose and usage of the Node.js cluster module

Node.js is a single-threaded programming environment, which means that it can only process one task at a time. This can be a performance bottleneck for applications that need to handle a high volume of requests. The Node.js cluster module provides a solution to this problem by allowing developers to create a cluster of child processes that can run in parallel, each handling its own requests.

What is the Node.js Cluster Module?

The Node.js cluster module is a built-in module that allows you to create a cluster of child processes. Each child process runs on a separate core of the CPU, allowing you to take full advantage of multi-core processors.

The cluster module provides several methods for creating and managing child processes. These include:

• cluster.fork(): This method creates a new child process and returns a reference to the worker object.
• cluster.isMaster: This property is true in the master process and false in the worker processes.
• cluster.workers: This property is an object that contains…
