NodeJS is an open-source server-side runtime environment based on Google Chrome’s JavaScript V8 Engine that was designed for the development of fast and scalable internet applications.  Otherwise known as the JavaScript runtime, it is designed to provide programmers and other developers with a lightweight, quick, and contemporary means to execute code in their local environment.

What is the purpose of Node.js?

A Node.js application that can manage a high number of simultaneous connections is the ideal use case for the technology. A wide range of mobile, desktop, web and IoT applications may benefit from Node.

There are several things it can’t accomplish. You need to add another technology to your tech stack if your programme has to compute and manipulate a lot of data (such as video processing) since it’s not good at it. However, the JS environment is always growing, thus this may change as well.

Only a few VR/AR apps and corporate applications are created with Node.js. There are several causes for this. In the first place, it’s possible that developers prefer to use technologies they’re already acquainted with.

With that out of the way, without further ado, here are the top ten most popular NodeJS applications examples available right now.

Top Node.js App examples 

Node.js App Examples that we are going to present each used one of the greatest Node.js characteristics – and achieved quantifiable and good outcomes as a consequence.

1. PayPal 

In more than 200 markets, the platform lets its customers conduct online transactions with one another swiftly and simply in more than 100 currencies. Since its inception in 2005, the service has grown to include millions of active members, and it uses NodeJS for the user-facing side of its web application. 

By allowing both the browser and the server apps to be written in JavaScript, NodeJS aids in the resolution of this (the border between the browser and the server).  It brings together the technical expertise into a single team, allowing us to better understand and respond to the demands of the consumers at any point in the technological stack.

2. Netflix 

Netflix is the world’s leading supplier of video streaming services, including movies and television programmes, and is accessible in more than 190 countries across the globe. Node.js is used to build the entire user interface on Netflix.com. 

Node.js was chosen by the developers in order to offer a lightning-fast, modular, and lightweight application. Following the demonstration of the effectiveness of Node.js, the firm has opted to migrate its whole data access layer to Node.js.

3. LinkedIn  

LinkedIn is a professional networking and career development social network that primarily caters to professionals. LinkedIn is accessible in 24 languages. Moreover, guess what? The server-side of LinkedIn’s mobile application is powered by Node.js.

The new mobile app has greater speed, consumes less memory, and is 20 times quicker than the old Ruby on Rails-based version. It also has a smaller footprint. Furthermore, resource consumption has been significantly improved, resulting in a tenfold reduction in the number of servers required to execute the mobile application!

4. Uber 

With its cab app, Uber is a transportation network corporation that is best known for its ride-hailing services. By implementing a new business model, the corporation was able to alter the course of transportation history. 

Uber is now accessible in 85 countries and over 900 cities throughout the globe. In fact, Uber was one of the first firms to put Node.js into full production, when it created a large matching system using the Node.js framework. 

Thus, as a result of the technology choice to use Node, Uber’s app significantly improved its performance, processed information more quickly, increased the operational speed of the application, and errors could be addressed immediately without the need for a restart.

5. eBay 

Founded in 1995, eBay is a popular online shopping website in the United States and the best node.js sample application. It is best known for its auctions, consumer to consumer sales, and business to consumer sales. 

eBay’s speed and simplicity, as well as its scalability, transparency, and control, have all increased as a result of the migration to Node.js.

6. Yahoo 

Yahoo is an online service based in the United States that offers a variety of services such as a search engine, email, news, and finance. In order to develop their content websites and single-page apps, the firm use Node.js technology.

When Yahoo switched to Node.js technology, its speed and scalability increased significantly, and the company was able to handle more queries per second.

7. Twitter 

Twitter engineers switched all of the company’s traffic to a new Node. js example technology stack, which has now become the industry standard. Among the causes of their most recent woes are politicians who have taken use of the platform (as well as other social media platforms) to further their personal interests in unscrupulous ways. 

A number of additional difficulties have arisen, but they have always managed to overcome them. The social media site Twitter may not have the most users, but it is unquestionably the most influential.

Every developer at Twitter has been pleased with the development speed that Node.js provides, and they’ve taken advantage of this by incorporating the technology into every project they could.

8. Coursea 

When it comes to massive open online courses (MOOCs), Coursera is unrivalled in terms of size and scope. It makes it possible for anybody to attend classes from the world’s finest institutions, which is especially beneficial for individuals living in low-income neighbourhoods.

They collaborate with colleges, businesses, and non-profit organizations. Individuals from all around the world have access to more than 3,800 courses, which is an impressive feat. Coursera is the ideal mix of massive volumes of information, video streaming, and high levels of user traffic, making it an ideal Node.js application.

9. Medium 

Medium, an online publishing platform that was launched in August 2012 and uses NodeJS for its web servers, is a good example of this.

Medium makes use of NodeJS in order to build web servers that are capable of serving a diverse range of content to its consumers. The firm also reduces deployment times by up to 15 minutes, which adds significantly when you’re a developer who has to deploy numerous times each day!

10. Groupon 

Founded in 2008 in the United States, Groupon is a worldwide eCommerce platform that links customers with local businesses by providing daily offers on local products and services such as restaurants, theatres, and retail shops. 

The firm is able to service the same amount of traffic with less hardware as it did with the previous design as a consequence of this change. Teams may also make improvements to the application more independently and quickly than they were previously able to.

Technical Reasons for Using Node.js 

As we’ve seen, Node.js can be used to tackle a wide range of business challenges, from reducing development time to improving user experience. However, there are a few additional reasons why you should go with this.

• Usability

When you don’t need to re-invent the wheel, you can use Node.js. As a result, development time is sped up and less code is required.

• Microservices

As an event-driven I/O paradigm, Node.js is well suited to microservices architecture development. In the real world, this implies that each request from a user is routed to a specific section of the programme and is immediately answered by that section.

Node.js provides many advantages over Java as a backend platform, including the following:

• The same amount of functionality may be developed in twice the amount of time.
• Reduced programming effort 
• It’s possible to get more out of Node.js than you bargained for. Node.js is an excellent option if you want to build an interactive application with a huge number of users, many queries, and dynamic data.

So, Is Node.js a viable option for your project?

Yes. 

It’s reliable, it’s really quick, and it readily grows up to the extent that you want – both in terms of the number of users and the overall speed of the app. Node.js is a fantastic option for high-traffic, real-time applications such as single-page apps, mobile applications, and cross-platform applications in web development, mobile development, desktop development, and Internet of Things development.

When utilised appropriately, Node provides enhanced performance over rival technologies, as well as a superior user experience compared to other technologies.

Summary 

Node.js is being used on the backend of many large organizations’ applications because of its benefits, which include great performance, simple scalability, high extensibility, and improved efficiency. However, keep in mind that Node does not operate in a vacuum. Node.js specialists, professional website designer and UX/UI designers of the highest calibre are required if you want to take full use of this technology’s full capabilities.
