There are 810 million users in more than 200 nations. In 2011, the business switched to an event-based asynchronous system from its Ruby On Rails-based synchronous backend mobile architecture. Because of Node.js’ exceptional scalability and performance efficiency, LinkedIn decided to move to it.

Why Node.JS

  • provides developers with a means of scaling and communication with other relevant services.
  • Improve performance while allowing minimal memory overheads.
  • Mobile backend and frontend engineers could work together as one team.
  • There is still enough headroom to handle 10 times the present levels of resource utilization.


The initial step was developing real-time applications, which necessitated maintaining live server connections. The synchronization of a number of eBay-specific services that display data sets directly on the website was the second stage. NodeJS was chosen by the eBay development team because it delivered good results rapidly and with less resource use.

Why Node.JS?

One of the largest online payment systems in the world, PayPal enables digital payment and serves as an electronic replacement for traditional paper methods like cheques. With 377 million active users as of 2021, the company is present in over 202 countries and territories. Before switching to Node.js, PayPal’s engineering teams were divided into two groups: one that wrote code for browsers using HTML, CSS, and JavaScript, and another that wrote code for application layers (making use of Java). The separation between the browser and server was thus the main impediment for the business. The organization used the same language for both the browser and server applications after deciding to switch from Java to Node.js.

Why Node.JS?

The fact that the engineering teams at PayPal were divided into those who wrote code for browsers (using HTML, CSS, and JavaScript) and those who wrote code for servers (using Java) presented a significant challenge for them. Therefore, using JavaScript in a single language for both the server and the browser was the best course of action.
