Why Node.js?

Node powers big brands

In the five years since its debut, Node has gone from a language inspired by the desire for websites to support push notifications, to a language that is now powering some of most innovative initiatives at companies of all sizes. How did this happen? A big driver has been the rapid proliferation of mobile apps and the need to connect them to data and services via APIs. And, to do it in a way that is both scalable and easy.

Here’s just a sample of the many companies using Node in production or ramping up projects:

Node is fast and scalable

Everyone knows benchmarks are a specific measurement and don’t account for all cases. Sometimes Java is faster. Sometimes Node is. Certainly what and how you measure matters a lot. But there’s one thing we can all agree on: At high levels of concurrency (thousands of connections) your server needs to go to asynchronous non-blocking…you can’t go creating threads for every connection. This is where Node excels.

Node is for APIs, mobile, web and IoT

Node has emerged as the go-to technology for a variety of use cases, including:


The “glue” that connects devices and browsers to data and services




Backends and full-stack JavaScript hybrid apps


HTTP servers and single page apps
