10 Most Popular NodeJS Apps of 2020

Okay okay, we know you have been blasted with articles on NodeJS, how wonderful JavaScript is, and how JavaScript is literally taking over the world of web development. There are good reasons for this, with the largest tech companies and internet applications adopting NodeJS in their tech stack, big time. This is why we wanted to list the most popular NodeJS of 2020, but first, what is NodeJS again?


What is NodeJS again?

To avoid dragging things out, long story short — NodeJS is an open-source server-side runtime environment built on Google Chrome’s JavaScript V8 Engine, created for building fast and scalable internet applications. In other words, it is simply a JavaScript runtime, providing developers a lightweight, fast, and modern way to execute code on their local environment.


With that out of the way, without further ado, here comes the 10 most popular NodeJS apps out there…


1. Paypal & NodeJS

In a recent article on how was PayPal developed, we explained how PayPal went from an online payment service predominantly built on Java to a payment platform powered by NodeJS. The platform enables its users to transact with each other online quickly and easily in more than 100 currencies across more than 200 markets. As of 2015, the service has over 184 million active users, using NodeJS for their user-facing side of its web application:

Jeff Harrel, Senior Director of Payments Products and Engineering at PayPal elaborates:


“NodeJS helps us solve this (boundary between the browser and server) by enabling both the browser and server applications to be written in JavaScript. It unifies our engineering specialties into one team which allows us to understand and react to our users’ needs at any level in the technology stack”.


According to Brainhub, the NodeJS efforts has provided PayPal with great technical returns, loading the web application almost twice as fast with fewer people, in 33% fewer lines of code, and 40% fewer files compared to their previous Java-based application.


2. Netflix & NodeJS

Netflix is the world’s largest provider of video streaming including movies and series, available in over 190 countries. As of April 2016, Netflix reported over 81 million subscribers worldwide, with more than 46 million in the U.S itself.

As explained in how was Netflix developed, the whole user interface on Netflix.com is built with Node. The engineers decided to use Node.js in order to deliver a blazing-fast, modular, and lightweight application. Accordingly, Netflix’s web app load time has been reduced by 70%. Node.js has proven to be an effective solution, so the company decided to move the entire data access layer to Node.

3. LinkedIn & NodeJS

LinkedIn is a social network that mainly focuses on professional networking and career development. LinkedIn has over 675 million members in 200 countries and regions worldwide and is currently available in 24 languages. And guess what? Node.js powers the server-side of LinkedIn’s mobile app.


The new mobile app is with better performance, consume lower memory, and is 20 times faster than the previous Ruby on Rails-based version. Furthermore, resource utilization was greatly improved, cutting down the number of servers needed to run the mobile app by a factor of 10x!

4. Uber & NodeJS

Uber is a transportation network company best known for their ride-hailing taxi app. Implementing a different business model, the company changed transportation forever. Today, Uber is available in 85 countries and over 900 cities worldwide, completing more than 14 million trips every day.


Uber was one of the first companies that adopted Node.js into full production as it built a massive matching system on Node.js. Accordingly, Uber’s app drastically improved its performance, processed information quickly, boosted up the operational speed of the application and the errors could be addressed immediately without requiring a restart, all because of the tech choice of using Node.

5. eBay & NodeJS

eBay is an American online shopping website, best known for its auctions, consumer to consumer, and business to consumer sales. The total users of the e-commerce giant have increased dramatically, and by 2019 surpassed 183 million users.


Node.js is part of the eBay’ tech stack. To the question why they chose Node.js, the Principal Web Engineer at eBay, Senthil Padmanabhan, says:


“We had two primary requirements for the project. The first was to make the application in real-time as possible–i.e., maintain live connections with the server. The second was to orchestrate a huge number of eBay-specific services that display information on the page–i.e.”


After the switch to Node.js, eBay improved its speed and simplicity, scalability, as well as transparency and control.

In June 2015, Groupon migrated the whole web and mobile traffic from a Ruby on Rails stack to a new Node.js stack. As a result, the company serves the same amount of traffic with less hardware compared to the old architecture. Additionally, teams make changes to the application independently and quicker than before.
