What is Node.js and it’s Advantages?

Node.js is a software platform developed on the V8 JavaScript engine by Google. It is a cross-platform runtime environment developed specifically for networking and server side applications. It is developed in JavaScript and it could be run within its runtime on different operating systems. These include Linux, Windows and OS X without any changes. It was created in 2009 by Ryan Dahl, and was sponsored by Joyent.

Why Use NodeJS

Node.js applications are developed for maximizing throughput and efficiency. This is done through the use of unparallel events and non-blocking Input/Output. Because of its asynchronous properties, it is mostly used for developing real-time programs.

At its core level, the framework uses Google’s V8 JavaScript engine for execution of code. A significant percentage of its modules are written in JavaScript. It has a built-in asynchronous IO file library, HTTP communication and socket. All this helps the programs developed on the platform to work as Web server. This is achieved without the need for any program, such as Apache HTTP Server.

Importance of NodeJS

There are many advantages of using Node.js. Some of the main reasons for using the platform for developing your custom application are as following:

  • It is easy to install and run.
  • It is vastly scalable because of its asynchronous and event-based processing.
  • It is based on combined programming language and uses unified data type.
  • It is economical to test and deploy using pay per resources services.

Among other advantages, NodeJS helps save time and money while delivering a scalable and efficient solution.

How NodeJS is Different

Node is especially different from other server-side frameworks.It uses an asynchronous thread and a single thread structural design. A significant percentage of other server-side technologies are synchronous and multi-threaded. This means that each request results in creating a new thread from a limited pool depending on the use of RAM.

Node isn’t just designed to replace other frameworks. It can help bring enhanced performance and scalability to programs. It is ideally suited for developing applications like Real Time Tracking apps, REST APIs and Chat apps. It is lightweight and highly efficient. This makes it ideal for highly data intensive environments that run over different devices.

NodeJS’ use of JavaScript and asynchronous architecture make it quite appealing to web developers. Node.js is a relatively new technology and may not be a full-fledged replacement for other server-side technologies. It is quite capable of handling specific needs.
