In today’s times, Node.js is aiding the web development process by offering incredible benefits to its users. When the advantages and disadvantages of Node.js have been considered almost all people come to a consensus that it is a completely dedicated runtime ecosystem and environment.

Node.js is considered one of the best tools in the web development industry because it can be very easily and simply used as a server-side alternative. It tends to manage a huge amount of concurrent connections and nodes in an unblockable manner.

Node.js makes a good match as a back-end tool with Angular being used as the front-end tool in the web integration. It might not be the most recent framework that can govern the web development world but it is a platform that fills a particular void in the market.

What is Node.js?

Node.js is a runtime environment engineered on Chrome’s JavaScript which is used by developers to create quick, scalable, and adaptable network applications. All applications developed using Node.js run on codes that are written in JavaScript. They can easily be used on OS X, Linux, Windows, etc.

The platform offers a case-sensitive shift across the software for setting up server-side and networking applications without any difficulty. It operates with an object-driven, non-blocking I/O framework that makes it extremely lightweight and hence, good for data-intensive live apps and webpages that are used on various platforms and devices.

Why Node.Js is Popular?

Node.js is a very powerful tool that is used to run JavaScript-based applications on both the server-side and client-side. It is capable of managing a gigantic number of simultaneous networks with high production.

The single threading of the platform is also highly beneficial for the development time because it supports thousands of real-time connections held in a particular event loop.

Node.js is not like the other web developing platforms and software where each connection runs on a separate thread that maxes out the amount of RAM provided; it operates on a single thread saving up all that extra RAM.

The response time for Node.js can be deducted easily by making it work faster by adopting some practices like running it in parallel, going asynchronous, caching, gzip compression, optimizing your queries, etc.

Offers Non-blocking I/O Paradigm and Reusable Code

Node.js solves the problem of waiting for a long period for a response while using I/O operations by using a non-blocking Application Programming Interface (API). As Node.js uses a single thread, waiting for a response might block the entire application so, it has to be of non-blocking API so that other tasks can be done.

As it uses a non-blocking API, Node.js tends to call for it, and then the thread continues to work on other tasks and as the Input/Output operation is completed, the developer gets a notification about the same. This approach is beneficial because it improves the efficiency and effectiveness of the platform as it tends to handle a lot of concurrent connections.

It also offers the feature of reusing the code, where, the same code can be used for both back-end and front-end operations and working of a particular application. Different parts of the code can be shared within various components across the system.

Offers Remarkable Performance and Scalability

The apps that are developed using Node.js are mostly programmed completely in JavaScript and plug and play interworking always leads to great speed and amazing performance. The code tends to run very quickly and hence, improves the complete duration and run-time environment of the given platform.

While using Node.js, you are allowed to scale vertically, adding new capable ways that lead back to your core application code. The platform also offers horizontal scalability which helps in adding new resources to existing programming. Both ways, scalability gives your application the space to grow. Every node in Node.js relies on an ‘event’.

Offers Cost-efficiency and Faster Time-to-market

As Node.js is an open-source platform, it is much more cost-effective than any other alternative that offers JavaScript servers.  It is a very lightweight Language and it can excessively lessen the application development time while providing the same incredible functionality.  Hence, it is very helpful in making the time-to-market cycle comparatively shorter.

With Node.js at work, small companies and start-ups can easily convert an idea into a working product as they already have less time, small budgets, and lean teams; Node solves this problem for them. It does not require any alternative server-side languages to work.

And, it is an important factor because it speeds up the development process in almost every space and allows developers of all levels easier access to your mobile apps’ back-end.

Has Huge Popularity in the Industry

Many popular apps like Netflix, eBay, Yahoo are using Node.js to run across various platforms and devices. The giant OTT platform, Netflix is built with Node.js as its foundation. The platform had chosen the Node.js framework because it aimed for lightweight and smoothly fast streaming for a buffer-free experience for its audience.

Paypal, the world-famous payment gateway application uses Node.js to build the consumer-facing side for its web application.

The famous taxi booking app, Uber had also chosen Node.js to be its framework because it has massive data to process and also, GPS integration at work. The framework aided the app in processing information like taxi requests, driver arrival, etc. quickly.
