Use it to get information like environment variables, and CPU and Memory usage. The process object provides information about your Node.js application as well as control methods. Clusters: Allow you to fork any number of identical processes across cores to handle the load more efficiently.Child Processes: Allows you to run sub-processes that you can monitor and terminate as necessary.Useful for CPU-intensive JavaScript operations. Worker Threads: Used to separate the execution of functions on separate threads to avoid bottleneck.Streams: Used to process large amounts of data in smaller and more manageable chunks to avoid memory issues.Works similarly to client-side event listeners. Events: For emitting and subscribing to events in Node.js.File System API: Interact with the file system to create, read, update, and delete files, directories, and permissions.Util: A collection of useful and common methods that help with decoding text, type checking and comparing objects.OS: Retrieve OS and system related information that Node is running on: CPUs, Operating system version, home directories, etc.Process: Retrieve information on environment variables, args, CPU usage and reporting.When building your first Node.js application it’s helpful to know what utilities and APIs node offers out of the box to help with common use cases and development needs. It also includes quizzes, videos, code to run your own docker containers. Check it out there to follow comprehensive course to build your own multi-user real time chat application. This guide has been adapted from my course Node.js: Novice to Ninja.

For each module you’ll find simple english explanations and examples to help you understand. We’ve compiled a list of the most used and useful APIs that are built in to the standard Node.js runtime.
