What Is NodeJS and Its Benefits for Business Applications?

 What is Node.js- 

Node.js is used to develop server-side applications in JavaScript and uses the same JavaScript language syntax as you write for client-side apps. Node.js is a cross-platform runtime environment for developing server-side applications. You can build Node.js apps using any language that compiles to JavaScript, including Java, C#, Objective-C, and C++. Node.js is a server-side environment built on top of JavaScript. It’s lightweight and efficient for creating fast web apps. Node.js gives you the power to create powerful server-side web apps using JavaScript, and it doesn’t require you to know any other language because all your code will be written in JavaScript.

How does Node.js work?

Node.js is a cross-platform runtime environment built on top of Google Chrome's V8 JavaScript engine. This technology is used to build server applications using JavaScript and an asynchronous non-blocking I/O API to improve performance when handling multiple requests at the same time. It's very popular among developers, having been downloaded over 61 million times according to Frameworks Monitor and being in use at companies like PayPal, Netflix, Uber and Walmart.

Parts of Node.js

Features Of Node.js-

• Easy- Node.js allows the server to be written in JavaScript. It’s a perfect choice for beginners as it’s simple to learn and has a large and active community. Node.js is especially useful for mobile applications that need real-time data updates on queries or user events.

• Scalable- Node.js is a server-side JavaScript engine that's highly efficient at running applications over the web. Node.js has been gaining popularity in recent years due to its ability to handle a large number of connections and its single-threaded architecture, which allows Node.js to be used for long-running processes and event loops.

• Speed- Non-blocking events allow for the simultaneous processing of many tasks and make it possible for Node.js to handle thousands of concurrent connections. This, in turn, can significantly improve the performance of your application.

• Packages- NPM is a package manager for the JavaScript programming language. It was packaged with Node.js and is used to install, publish and manage open-source libraries and packages..

• Strong backend- Node.js is an open-source JavaScript runtime built on Chrome's V8 engine, created to build scalable network applications.  Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications.

• Maintainable- Node.js provides a highly scalable, event-driven, non-blocking I/O model that makes it lightweight and efficient. Having a single language across the client and server also means more rapid application development and shorter learning curves for emerging technologies such as IoT.

Applications Of Node.js- Node.js is used for a wide variety of applications:

1. Real-time chats-  Node.js is a JavaScript runtime based on Chrome's V8 engine that lets you build fast and scalable network applications rapidly. Node.js is well-suited to processing real-time communication and can easily scale, making it ideal for building chatbots.  Node.js is a powerful framework for building websites and apps. It makes it simple to build additional chat features like multi-person chat and push notifications.

2. Internet of Things- Most of the IoT applications typically consist of multiple sensors, sending small chunks of data. Node.js is a good choice since it’s able to handle these concurrent requests quickly - and easily at that.

3. Data streaming-  The streaming API provided by Node.js allows for the creation of streams that pipe requests to each other. This results in data being streamed directly to its final destination, rather than being stored and transmitted later on. This is particularly useful for sites like Netflix who rely on streaming content, as users can use this technology to get the best possible experience without interruptions.

4. Complex single-page applications (SPAs)-  SPAs use JavaScript to create a single page in which all of their application’s content will be loaded. This usually means there are a couple of requests made in the background for specific components like stylesheets, images, and scripts. Node.js’s event loop comes to the rescue here, because it processes requests in a non-blocking fashion.

5. REST API-based applications-  Node.js is a JavaScript framework for building all kinds of applications, from simple websites to complex ones like the chat app. It has a huge community of developers which is always ready to help those who need it. With many packages available for building web applications, you can get started in no time on any operating system.

Advantages of Node.js Development-

Node Package Manager (NPM): Node Package Manager, or NPM, is a package manager for the JavaScript programming language. A package manager is an application that allows us to install new software packages and manage them easily. So, with NPM we can install thousands of different tools or libraries in our app with just one command.

Node.js uses asynchronous programming: In Node. js, all APIs are asynchronous – i.e., non-blocking. This means the server does not wait for the API to return data but proceeds to call another API while waiting for the previous one to return data. The server also uses an event loop that manages input and output events as they come in so that no request has to be blocked, thereby keeping the server efficient and fast.

Single-threaded: A single-threaded server process can only handle one request at a time. As a result, it can only service a few requests at the same time. Node.js is able to provide service to a much larger number of requests thanks to its event looping architecture.

Scalability: Node.js is a server-side framework that enables you to build fast lightweight and applications. Because of its super-fast processing capability, it’s very popular as compared to other frameworks like Ruby, Python, and PHP.
