Node.js Tutorial

Topics Covered

Node.js is a fast, lightweight, and scalable platform that can be used efficiently for developing many kinds of web applications. Here are some of the most important applications of Node.js that you will learn in this Node.js tutorial.

1. Real-time Chats

Node.js uses powerful event APIs that make it easy to manage server-side events and push notifications which are widely used in real-time applications.

2. Single Page Applications

Single Page Applications (SPAs) are used to create social networking applications. Node.js is a great fit for SPAs because it can handle asynchronous calls and heavy workloads of these applications.

3. Microservices Architecture

Node.js is the most widely used solution for developing microservices due to its repository features and highly flexible modules that can be used for specific parts of an application.
