Node.js is a server side platform built on Google Chrome’s JavaScript Engine (V8 Engine), for easily building fast and scalable network applications. Node.js is an open source, cross-platform runtime environment for developing server-side and networking applications.

Node.js applications are written in JavaScript, and can be run within the Node.js runtime on OS X, Microsoft Windows, and Linux. Node.js also provides a rich library of various JavaScript modules which simplifies the development of web applications using Node.js to a great extent.

Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. Due to its asynchronous, non-blocking, programming model for lightning-fast speeds and enabling the use of JavaScript on the server-side, both client and server run using the same language.

Until recently, highly concurrent programs were limited to hardcore network programmers. Now any web developer with JavaScript skills can write the same kinds of highly-scalable programs quickly and easily. Node.js changes the notion of how a server should work. Its goal is to enable a programmer to build highly-scalable applications and write code that handles tens, or even hundreds or thousands of simultaneous connections on just one server.

Advantages of Node JS

Interaction between client and server – Doesn’t require flipping back and forth between two or more technologies.

Platform control – Specifically as compared to a LAMP stack, with Node JS you have lot more power/control over what is happening on the server side, how a client connection is handled, how requests are handled, etc. You can do all of the same stuff with Apache/PHP. But it requires a lot more work, plugins, etc.

Code re-use – You potentially use any piece of code on both sides of the stack.

Other advantages – With respect to speed, size, scalability, etc.
