Beginners Guide : How to Install Node.js

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. 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.

In simple words – is server-side JavaScript. Every function in Node.js is asynchronous,Node.js uses an event-based server execution procedure rather than the multithreaded execution in PHP.

Node.js provide only an environment – meaning that you have to do everything yourself. There is not a default HTTP server, or any server for that matter. This can be overwhelming for new users, but the payoff is a high performing web app. One script handles all communication with the clients. This considerably reduces the number of resources used by the application.


if you use Windows or OS X; the website offers installers for those operating systems, go to and  you can directly install.

Installing on Windows

Probably asks for cygwin packages, if not installed.

The directory contains the latest .msi package (such as node-v0.6.15.msi when Node v0.6.15 was the latest) that you may use to install both Node.js engine and npm.

Installing on Mac

The directory contains the latest .pkg package (such as node-v0.6.15.pkg when Node v0.6.15 was the latest).

Building on GNU/Linux and other UNIX

There's a number of ways to install Node.js on Linux
The filenames vary with the Node's version. The following examples are for Node v0.6.18.


1. GNU make 3.81 or newer. Pre-installed on most systems. Sometimes called gmake.

2. python 2.6 or 2.7. The build tools distributed with Node run on python.

3. libssl-dev (Node v0.6.x only.) Can usually be installed on *NIX systems with your favorite package manager. Pre-installed on OS X.

4. libexecinfo (FreeBSD and OpenBSD only.) Required by V8. pkg_add -r libexecinfo installs it.

Do something like this

tar -zxf node-v0.6.18.tar.gz   #Download this from
cd node-v0.6.18
sudo make install

Or, if you'd like to install from the repository 

git clone
cd node
git checkout v0.6.18     #Try checking for what the stable version is
sudo make install

You may wish to install Node in a custom folder instead of a global directory. 

./configure --prefix=/opt/node
sudo make install
