9 Famous Applications Built Using Node.js Framework

Top Famous Apps Built Using Node.js Framework

Node.js has completely changed the perspective of people on JavaScript. It is an open-source cross-platform environment. It has become the most popular framework for backend development. Every organization now wants to hire a Node.js development company to take their business on the digital platform. With Node.js, developers can create social media applications, real-time applications, collaboration tools, online games, and much more.

In this blog, we will have a look at famous applications that are created using the Node.js framework.

What is Node.js?

Node.js is one of the most trending server-side runtime environments. It is mostly used for creating real-time applications that need to be fast and scalable. This JavaScript runtime environment allows Node.js developers to create applications that are light and cross-platform.

Node.js is a JavaScript framework that wastes no resources or time on waiting for the return of I/O requests. This technology runs a single-threaded event loop within your system for managing the connections. When a new connection is created, it fires the JavaScript callback function. The call function here can manage the requests with non-blocking I/O calls.

Which Biggest Companies are Using Node.js Apps?

Node.js, being a very comfortable technology to work with, attracts giant companies. Let us have a look at those companies and the reason why they prefer Node.js.

1. Netflix

Netflix is the world’s best OTT platform. It streams videos and media on the users’ demand. Currently, it has over 195.15 million subscribers around the world. This data-driven platform switched it’s backend from Java to Node.js. This is because Netflix uses a massive amount of A/B testing to provide a rich user experience and increase subscribers.

Besides this, they wanted to have a scalable solution that is able to handle user requests and one billion hours of video streaming per week. And this is something that a system with lightweight and less startup time can offer. Therefore, Node.js is the perfect option for Netflix.

2. PayPal

PayPal is an online payment platform. It is the first system to use Node.js technology in production. Initially, PayPal was using Java for the backend and JavaScript for its frontend. Then it tried to create a prototype in Node.js with a team of two developers. And then increased the Node.js development team to five developers. The result was such that the team of five Node.js developers caught up with the huge team of Java in much less time. Therefore, PayPal switched to Node.js.

By adopting the Node.js framework, the app development team at PayPal was able to solve many issues as it allowed them to write server and browser applications with the same programming language, i.e., JavaScript.

3. Trello

Trello is a popular project management tool with around 50 million registered users by the end of the year 2020. Trello is a tool that needs to rely on event-driven technology to manage open connections. Therefore, Trello used the Node.js framework for its server-side. Node.js also helps Trello in prototyping a tool to create single-page applications.

With Node.js, Trello can easily check everything and find out if it is going in the right direction or not.

4. Walmart

Walmart is a retail giant with net sales of 519.93 billion US dollars in the year 2020. It is one of the largest companies in the world revenue-wise. Walmart carries its retail operations in 27 countries all over the world. It provides sophisticated features to its mobile app users. To give them a better user experience, Walmart jumped to Node.js.

Walmart cherished the single-threaded event loop system and asynchronous I/O feature of Node.js as it has the ability to manage concurrent requests.

5. LinkedIn

LinkedIn is the top employment-oriented social media platform. It was taken over by Microsoft in the year 2016. Currently, it has 722+ million members from around 200 countries in the world. In the LinkedIn mobile application, the server-side is created using the Node.js framework. LinkedIn was initially using Ruby on Rails for its backend and then switched to Node.js. The reason for the switch was scalability and performance.

6. Groupon

Groupon is one of the most popular online markets for deals. It offers great deals for different types of services and products from various brands. Groupon initially used Ruby on Rails, PHP, and Java for its application but soon realized that everything is getting complicated because of these languages. Therefore, they switched to Node.js. Groupon is one of the largest production deployment platforms of the Node.js framework in the world.

7. Uber

Uber is a transportation service provider. Its application connects drivers with the customers who want to travel within the city or outside it. Uber used many tools and programming languages in its application to provide the best service to the users. Uber required a scalable and extremely fast cross-platform solution for the users. Considering the requirement, it jumped to Node.js. The main three reasons for choosing Node.js were — its ability to process huge amounts of data, ongoing changes & improvement in the technology, and error analysis & faster code deployment feature.


There is no need to give an explanation about NASA. It is the only reason behind us knowing everything about space. NASA needs to have a system that grants the utmost security to the people in an unfriendly vacuum. In 2013, during a regular spacewalk, one of NASA’s astronauts faced an issue. His spacesuit leaked water in the helmet and this was because of the system’s architecture.

After this incident, NASA decided to have a system that is created using a microservices architecture with the help of separate APIs and applications using Node.js technology.

9. eBay

eBay is an eCommerce giant with 183 million active users. It has always been open to new technologies. Because of its need for scalability, reliability, and faster solution, eBay opted for the Node.js framework. The main reason for choosing the Node.js framework was to have a real-time application to the extent and to orchestrate various eBay specific services. The Node.js developers at eBay made the application perfect by using this framework.

10. Twitter

Twitter Lite was released in 2017 for mobile users. It has minimum functionalities that can work on poor internet connection and also consume fewer internet data. The technology behind this application is Node.js. The Node.js developers of twitter created and delivered this application in no time.

Node.js App Development Performance Metrics

Let us have look at how the above-listed Node.js applications are performing in the market and how many followers these applications have -


Besides the above-listed applications, Yahoo, Mozilla Firefox, GoDaddy, Medium, and Yandex are some of the companies that are also using Node.js for engineering their apps. After having a look at such great examples, it is clear that Node.js is the best and most used framework in the market.
