PayPal
The world leader in online payment solutions transitioned to Node.js with the aim of breaking the
boundary between the browser and the server. Node.js helped them unify their engineering
efforts and react better to user needs. As a result, their new app was built almost twice as fast
with fewer people as opposed to their previous Java-based application.
Netflix
As the most popular video-on-demand provider in the world, Netflix uses Node.js for their entire user interface in order to have a lightweight, fast application with the lowest possible startup time.
LinkedIn
LinkedIn, the business and employment-oriented social networking platform, decided to move their mobile app from Ruby on Rails to Node.js because they wanted to achieve greater scalability and speed. As a result, their new app is lightweight, significantly faster than its predecessor, and uses a fraction of its resources.
Walmart
When Walmart, the world’s largest retailer, needed to improve its business and become an online retail leader, it decided to rebuild its app with Node.js. Node’s single-threaded event loop model helps the retail giant effectively handle a multitude of requests and keep its content consistently fresh.
Uber
Uber, the increasingly popular ridesharing service, uses Node.js in their app in order to be able to quickly process vast amounts of information. In case of errors, Node.js enables Uber developers to address them immediately, without requiring a restart.
eBay
When the online marketplace eBay was looking to create a high-volume real-time app that would support a vast number of live connections to the server, it decided to go with Node.js. Node also enabled them to coordinate and manage a large number of eBay-specific services that display information on the page.
