In fact, Node.js has become a go-to technology for several reputed companies around the world. Node.js is an open-source JavaScript-based technology that runs on JavaScript code on the server-side. Node.js is an ideal technology for fast, lightweight, and real-time web applications, such as audio/video streaming applications, gaming, chatting, etc.

Is Node.js really that great?

Node.js is written in JavaScript, one of the most reliable and popular programming languages for developing fast and scalable applications. Why is Node.js getting popular among the developers for application development? Here are some of the reasons:

  • Node.js provides a comfortable environment for developers.
  • Highly scalable and reliable technology for application development.
  • Node.js allows the server-side code execution.
  • Node.js follows quicker development cycles.
  • Noe.js has a large open-source community.
  • Node.js is the second most popular technology on GitHub with over 70,000 stars.

Thus, most reputed and top brand companies adopt Node.js development services for web app development due to all of the above reasons. So, to understand the reason for the rising popularity of Node.js, here we discuss the top brand companies who faced the challenges before the use of Node.js and how they solved their problem with Node.js?

Most Popular Companies that use Node.js for Application Development

Generally, Node.js development is used extensively used for web application development, but thanks to the Node.js ecosystem, it can also be used for mobile app development. Let’s begin with the list of the top and most popular brands apps that are built using Node.js technology:
