Business Description

In our previous article, we told you why we are in love with Node.js. We listed a few reasons, and we hope you already found a few valuable points in it.

In this article we want to introduce you to big and famous companies that have already become adherents of Node.js. Some of them even rebuilt their existing apps with Node.js.
To refresh your memory and remind what Node.js is, here we leave a link to our article where we described this technology in detail. Click on that link before continuing.

Now, that you are familiar a bit more with Node.js, you probably want to know what those companies are and why they prefer to build apps with that runtime.

#1 PayPal

PayPal is the largest and most famous payment system in the world. As of 2020, the platform has 305M registered active accounts worldwide and allows users to transact with 25 currencies all over the globe.
Before Node.js, the team of their developers used HTML, CSS and JavaScript for front-end and Java for back-end. It was pretty complex and complicated and in 2017 the company transferred its apps from Java to JavaScript and Node.js.
Node.js opened “the doors” for JavaScript development on backend and now entire app can be built in JavaScript.

#2 LinkedIn

It is an online service for business and employment. LinkedIn was launched in 2003 and still is very popular among workers and employers. It is available in 24 languages and as of 2020 has 675M members in over 200 countries.
After switching to Node.js, the development team of LinkedIn gained several interesting features:
 • The number of servers has decreased from 30 to 3.
 • Mobile teams could be combined into a single unit instead of separate front-end and back-end developers.
 • Performance became better, memory overhead lower.

#3 Netflix

Today we don’t know anyone who never heard about that American media services provider and production company. On July 10, 2020, Netflix became the largest entertainment media company with over 193 million paid subscriptions worldwide. Also, you can watch Netflix in more than 190 countries. It’s really a lot! The company initially used Node.js to enable high volume web streaming.
The development team used Node.js to implement three main goals to provide observability (metrics), debuggability (diagnostic tools) and availability (service registration). The result was the NodeQuark infrastructure.

#4 Uber

Uber is one of the most popular taxi and delivery applications. A lot of people use it not only for driving from one place to another, but also for food deliveries in times of the pandemics COVID-19. It serves in 69 countries and over 900 metropolitan areas. Also, Uber is a pioneer in the development of self-driving cars and one of the companies that put Node.js into full production.
According development team, Node.js was chosen because of three reasons:
 • fast processing of a large amount of information.
 • fast programs inspected and errors found, plus you don’t need to restart programs, so it saves time of the development process.
 • Node.js gets better all the time because community continuously optimizes the technology.
To build an uber-like app today is rather easy and if you want to create an own app with Node.js, our development team will be glad help you.

#5 eBay

eBay is a company which offers consumer-to-consumer and business-to-consumer internet sales services in 32 countries. The company has more than 13000 employees and more than 162M active users.
With Node.js the company realized two primary requirements for the project: maintain "real-time" connections with the server and organize a huge number of eBay-specific services that display information on a page.

Conclusion

Now you can see with your own eyes how many famous companies use Node.js as a technology for applications. It is fast, performant and uses JavaScript.
