INTRODUCTION With the emergence of numerous popular frameworks such as bootstrap, Angular JS, and others, the modern online application has come a long way. These frameworks are all built on top of the well-known JavaScript framework.

However, there was a hole in designing server-based apps, which is where learn Node.js came into play.

Although Node.js is built on the JavaScript framework, it is a backend development framework used to create server-side applications. Throughout the lesson, we'll look at the Node.js tutorial for beginners in-depth and see how we can use it to build server-based applications.

The frameworks available for web development for a long time were all based on a stateless approach. A stateless model is one in which the data generated in one session (such as user settings and events) is not saved for use in a subsequent session with that user.

WHY USE NODE JS In the following chapters, we'll look at the actual value of Node.js, but first, let's look at what makes this framework so popular. Most applications are built using a stateless request-response framework over time. In these kinds of apps, it's up to the developer to make sure to write the correct code to keep the user's web session alive as they work with the system.

You may now work in real-time and have two-way communication with Node.js web applications. The state is preserved, and the communication can be initiated by either the client or the server.

FEATURES OF NODE JS In this Node tutorial for beginners let's take a look at some of Node.js' most essential features: 1. Concurrent request processing is aided by asynchronous event-driven IO, which is undoubtedly Node.js' most compelling feature.

This functionality essentially means that whenever Node receives a request for an Input/Output operation, it will do the action in the background while continuing to process other requests.

This differs from other programming languages in several ways. The code below shows a simple example of this: var http = require('http'); http.createServer(function (req, res) { res.writeHead(200, {'Content-Type': 'text/html'}); res.end('Hello World!'); }).listen(8080);

APPLICATIONS OF NODE JS 1. Real-time chatbots 2. Game servers 3. Suitable for collaborative workplaces 4. Advertisement servers 5. Making Streaming Servers
