What Is Node.js and Why You Should Use It

Wikipedia defines Node.js as an open-source, cross-platform, back-end JavaScript runtime environment that runs on the V8 engine and executes JavaScript code outside a web browser.

Node.js is a single-threaded, open-source, cross-platform runtime environment for building fast and scalable server-side and networking applications. It runs on the V8 JavaScript runtime engine, and it uses event-driven, non-blocking I/O architecture, which makes it efficient and suitable for real-time applications.

Top benefits of Node.js

High-performance for Real-time Applications

One of the advantages of node.js is that you can create a supercharged application that displays results in the blink of an eye.

Web applications powered by Node.js take full advantage of its multitasking capabilities. Unlike other platforms, its single-threaded, event-based architecture efficiently processes multiple concurrent requests without clogging up RAM. In addition, its event-loop and non-blocking I/O operations allow code execution at speeds that significantly affect the overall performance of the application.

Easy Scalability for Modern Applications

Sophisticated technology comes with a lot of features like a cluster module. It features load balancing on multiple CPU cores, making it easier to deliver the desired results through smaller modules without burning the RAM process. Additionally, Node.js employs a non-blocking event-loop mechanism that provides high scalability and enables the server to process requests seamlessly.

From a development standpoint, Node.js allows you to take advantage of microservices that allow you to split your application into smaller parts. This way, you can define tasks to quickly track the development, deployment, and maintenance of each section of your application and efficiently allocate them across different teams. Node.js and Microservic allow modern applications to scale up and down as needed and help companies achieve higher performance with fewer resources.

Cost-effective with Fullstack JS

Node.js allows developers to write server-side code in JavaScript, so we can write codes on both the front end and backend with complete ease. This is the biggest advantage of node.js as it saves huge time, cost, and energy for overall project development as well as overcoming the hurdles of hiring two resource teams. Cost-effective with Fullstack JS is the only app you can build on your good budget.

Helps in building Cross-functional Teams

Let’s say you’ve employed two different teams for project development and quality testing, who work independently and whose responsibilities are confined to their expertise. Although this could sound ideal, chances are these teams have massive communication gaps, resulting in a mammoth of loopholes in your product.

Node.js offers full-stack development capabilities, so it helps you build a team focused on extending your development life cycle in which you can meet immediate challenges. This work environment adds value to healthy productivity and allows you to solve problems and solve problems properly. As a result, you are more likely to spend less time in the market.

Extensibility to Meet Customized Requirements

Businesses never grow. So whether you have increased your user base or are planning to explore other industry parameters, Node.js can be easily expanded and customized for fast-growing enterprises. Node.js can be expanded by taking advantage of the built-in API to develop data formats for HTTP and DNS servers and JSON, which makes data exchange between clients and web servers much easier.

Reduces Loading Time by Quick Caching

Node.js has made it easier for developers to reduce task workload and re-execute code with its caching module. So every time the first module of your web application receives a request, it gets cached in the in-app memory. That way, within a fraction of a microsecond, your users can quickly access web pages without having to wait long.

Features of Node.js

Here are a few exciting features of Node.js you should know:

Non-blocking I/O. : The main idea of this feature is to avoid things like synchronous thread, which starts a separate thread for each request and interrupts the whole process.

Instead of helping the webserver to start individual threads, Node.js allows working with so-called single threads, which are processed one by one. This helps to get rid of the synchronization between the threads and eliminate the problems associated with it.

Libuv. :  Libuv is a multi-platform C library designed primarily for use in the Node.js environment. This is exactly the component that allows the infinite processing of a single thread.

To be precise, Libuv creates a pool of up to four threads that are processed together. In addition, it sends requests to the operating system, which takes care of time.

 Significantly faster development environment: If you are a developer who likes to check their code from time to time, being able to see your code run in one second vs. 30 seconds for .net and java equivalent scale systems is a game-changer in terms of delivery speed.

Node Package Manager: Node Package Manager, also known as npm, is the default package manager for Node.js. Although you get many useful modules when you first install Node.js, you can better adjust the system to your needs with the help of Node Package Manager.

Node.js is a popular programming environment that can be used for building high-scale applications that need to support multiple concurrent requests. Node.js is the perfect tool to develop scalable web applications with great performance.
