Node.Js is an open-source, cross-platform, back-end JavaScript runtime environment that runs on the V8 engine and executes JavaScript code outside of a web browser.
It is used in most cases to build BackEnd services, better known as APIs (Application Programming Interfaces), these are the services that give power to web applications that run inside a browser or to a mobile application that is running inside a mobile device.
Several web applications and web pages the most used worldwide were developed with Node.js framework and here we give you the five most important, to serve as inspiration in your next project with this technology.
Web applications developed with Node.js framework
Netflix
The most famous streaming platform in the world and with almost 300 million users. The Netflix app and website switched its backend from Java to Node.js, which has been a huge boon to its ongoing A/B testing to deliver the best user experience. Also, the move to Node provided a scalable solution to handle user requests and millions of hours of streaming per day. The Node.js documentation is very comprehensive, which is of great help to developers.
PayPal
The online payment platform par excellence and one of the most visited web pages on a daily basis in the world. When it started, the web application was developed with Java for the backend and JavaScript on the frontend, then prototyped using Node.js, this was done with a team of two Node.js developers, later growing to five, with excellent results and exceeding the end product that was built using Java, so PayPal switched to Node.js entirely.
Trello
This project management tool, in which more than 50 million people enter every day to organize their tasks, whether personal or professional, used Node.js to develop its server side. They also used it to prototype single-page apps.
Walmart
The retail giant, the most popular supermarket chain in the United States, chose to use Node.js tools in its backend service to provide a better experience to its users, who since 2020 have increased their purchases through the web application. Walmart appreciated the single-threaded event looping system and asynchronous I/O feature of Node.js as it has the ability to handle concurrent requests.
The social network for your professional life. With over 700 million active members, LinkedIn used Node.js on the server-side for its mobile app, when it initially used Ruby on Rails but decided to make the switch, motivated by scalability and performance.
