Reasons Why You Should Choose NodeJs for App


JavaScript is a popular programming language among developers and one of the most widely used development technologies. JavaScript was initially developed to serve as a web frontend development tool. However, over time, it developed into a significant mobile development tool and platform foundation for a number of other platforms. JavaScript continued to dominate server-side programming as a result of its growing popularity and ease of use. This transition to web development was made with the help of Nodejs, which quickly gained widespread popularity.

In this blog, you will learn why you should choose Node.js for app development but before proceeding further, let us know about Node. js.

Understanding Node.js

Node.js is a server-side platform based on the JavaScript Engine, more commonly referred to as the V8 engine, of Google Chrome. It is a cross-platform, open-source runtime environment used for building networking and server-side applications.

Because it uses an event-driven, non-blocking Input-Output model, it is ideal for developing data-intensive real-time applications and is extremely light and efficient. Nodes applications are scalable and quick.

Now that you have understood Nodejs, now let us tell you why you should choose it over others. 

Reasons Why You Should Choose NodeJs For App Development

Now we will tell you why you should choose the Node.js framework for your business:

  • Speed With Node.js

Node.js is praised for its speed by businesses. Google’s V8 engine is used in Node.js, which compiles JavaScript into native machine code and runs extremely quickly. Node.js has a single thread, the event loop, that is in charge of all asynchronous I/O operations. This eliminates the need to create multiple threads, which can lead to problems with locking.

Node.js makes it easy to quickly complete common tasks in web applications, such as reading or writing to the database, network connections, and the file system. Businesses can use Node.js to create network applications that are quick, scalable, and able to handle a lot of connections at once. 

Nothing is slowed down by Node.js; Node.js applications follow the correct procedure because developers only need to write the code. Moreover,  you can hire dedicated developer who can help you in creating network applications with Node.js.  

  • Data Streaming with Node.js 

Although HTTP requests and responses are actually data streams in legacy web platforms, they are regarded as distinct events. Because data comes in the form of streams, this feature can be used to its full advantage when paired with Node.js to create fantastic features like processing files while the upload is in progress, which helps cut down on overall processing time. This can also be used to encode audio or video in real-time.

  • Ubiquity Of Node.js

Because of Nodejs, JavaScript can now be used both in the browser and on the server. Node.js code written for the server or the browser runs the same way on both. Node.js code migration can be easily taken over by a company that insists on changing the logic built for the browser to be moved to the server.

  • Database Queries With Node.js

JavaScript is used to write database queries for brand-new NoSQL databases like CouchDB and MongoDB. When combining Nodejs and NoSQL databases, developers do not need to shift gears to remember the differences in syntax.

In contrast to Ruby on Rails, which necessitates conversion from JSON to binary models, Node.js excels with real-time web applications due to its use of the JSON-stored data format.

  • Proxy Server

Node.js can be used to collect data from multiple sources or to proxy various services with varying response times.

For instance, Node.s can be used as a proxy for a server-side application that stores videos or images, collects data from various sources, or communicates with third-party resources. 

This is the case even if the business does not have an existing infrastructure for proxy or requires local development for this solution.

  • Effective Tooling With NPM

The Node.js package manager, or NPM for short, is similar to package managers from other ecosystems, but NPM is extremely robust, consistent, and quick, all of which contribute to effective dependency management. 

There are more than 60000 modules available to users, and this number is rapidly growing. As per the best custom mobile app development company India, the node community is stronger than ever as a result of growing interest in Node.js.

  • Increased Productivity With Node.js

Since JavaScript is used to create all Node.js programs, the silos between front-end and back-end developers have been completely broken down. This has made the web development process more efficient at various organizations. By avoiding inter-silo dependencies, businesses can efficiently combine the frontend and backend teams into a single unit.

Using Node.js, PayPal has measured an increase in developer productivity. Applications were delivered in a fraction of the time and with a half-time increase in developer productivity.

  • Node.js – A Single Codebase

Node.js makes it simple for developers to write JavaScript on both the server and the client, making it easier to automatically synchronize data between the server and client. 

Meteor, a Node.js -based web app framework, uses the same codebase on both the client and server. The changes to the data that are made on the server immediately show up in the client, and the webpage that shows this data updates itself automatically.

  • Easy To Build Real-Time Web Applications

Node.js makes it possible for developers to create comet-driven real-time web applications in the same amount of time it takes to bake a birthday cake using a ready-made mix or create a straightforward blog using PHP.

As a result, developers need not be concerned about low-level sockets and protocols. Multi-user real-time web applications like games and chat applications require Node.js.

The event loop takes care of the need for multiple users by using the web socket protocol, which runs on TCP and avoids the overhead of HTTP for web development.

  • Service Providers Hosting

Hosting is also flourishing as Node.js adoption rises. Nodejs deployments to a single command are now officially supported by PaaS (Platform as a Service) service providers like Heroku and Modulus.

As a result, a company can hire app developers in India who can employ Node.js and build a new product that reduces the number of servers required to host the application by half and increase employee retention to keep developers and customers satisfied.

Popular Examples of Node.js Apps

Node.js is used to build scalable desktop and mobile apps, as well as web and IoT projects that have to handle a lot of connections without any problems. 

After years of using other runtime environments, some of the most popular apps switched to Node.js for this reason.

Some of them are:

  •  Netflix

With over 150 million subscribers in over 190 nations, Netflix is the most popular streaming service in the world. It has a large collection of movies and TV shows, including some that were made in-house.

In addition, Netflix is well-known for spending a lot of money on expanding and improving its services. Netflix spent $1.5 billion on development in 2019 alone, spending $150 million per year to improve its recommendation system. Additionally, Netflix has been utilizing AWS for approximately $9.7 million per month since 2016.

When it comes to streaming huge amounts of data to thousands of users simultaneously, Node.js is the best option. It has helped Netflix handle the huge amount of traffic it gets.

  • Twitter

With over 330 million active users on a monthly basis, Twitter is a very popular social networking platform. Additionally, it ranks among the top ten most visited websites worldwide.

Twitter has undergone numerous redesigns and changes since its launch in 2006. In 2017, the company made the decision to move to Nodejs. Ever since Twitter’s developers started using Node.js, they’ve been pleased with the speed with which it allows for development.

The need for a language that would enable Twitter to rapidly implement changes was the primary driver of the switch. That was exactly what Node.js was, and ever since then, it has made it easier for the business to grow and move faster.

  • Slack

Slack is a tool for collaboration that makes it easier for people to communicate and collaborate more effectively. It is utilized by NASA, Airbnb, and eBay, among others, and it has more than 12 million active users.

Due to its event-based architecture, which makes it ideal for real-time applications, Node.js was chosen by Slack. The environment that the company needed to accommodate a large number of concurrent users was perfect.


Nodejs is a revolutionary technology. It has everything you need to create high-performance real-time web applications. As a result, there is a clear explanation for why Node.js has gained traction and continues to attract attention. Even though the community and technology have changed the framework, it still shows signs of progress.
