Why use Node.js?

Node.js is ideal for building scalable back end services that power client applications.

There are other popular frameworks such as Django, Rails or Laravel that are also designed to build back end services. So, what is so special about Node?

  • More accessible – Since Node uses Javascript as its programming language, most front end developers can understand Node for the backend, without having to learn another language.
  • Highly scalable – Developers can easily extend Node.js to cater for project requirements. The Javascript runtime environment can be scaled both vertically and horizontally.
  • Fast performance – Node.js is developed on Google Chrome’s V8 JavaScript engine. V8 possess incredibly fast code execution speed that significantly boosts the performance of web server applications.
  • Open source libraries – pretty much any features or you want to add to your application are usually available in open source libraries. Therefore, you don’t have to build any building blocks from scratch.

 

Node.js examples

A notable example to demonstrate the capabilities of Node.js is Netflix. Previously, Netflix was using Java on the back end and JavaScript on the front end. This required the company to hire developers who were proficient in each of these programming languages. Consequently, this added more work hours to handle errors, debugging and activity tracking.

Netflix now uses Node.js for several reasons:

  • One language for both the browser side and the server side reduces time input and costs
  • High performance is especially useful for sites like Netflix which offer instant streaming services
  • Many open-source modules available
  • A simpler way to write, engineer, and debug

Security in Node.js has become a more prominent issue now it is being used more and more for important projects. Following any reliable Node.js tutorial will help to avoid any security apprehension you may have.
