Node.js - Environment Setup
Local Environment Setup
If you are still willing to set-up your environment for Node.js, you need the following two software’s available on your computer, (a) Text Editor and (b) The Node.js binary installable.
Text Editor will be used to type your program. Here are a few examples of editors: Windows Notepad, OS Edit command, Brief, Epsilon, EMACS, and vim or vi.
Name and version of text editor can vary on different operating systems. For example, Notepad will be used on Windows, and vim or vi can be used on windows as well as Linux or UNIX.
The files you create with your editor are called source files and contain program source code. The source files for Node.js programs are typically named with the extension ".js".
Before starting your programming, make sure you have one text editor in place and you have enough experience to write a computer program. After writing the program save it in a file, and finally execute it.
The Node.js Runtime
Node.js distribution comes as a binary installable for SunOS , Linux, Mac OS X, and Windows operating systems with the 32-bit (386) and 64-bit (amd64) x86 processor architectures.
Following section guides you on how to install Node.js binary distribution on various OS.
Download Node.js archive
Download latest version of Node.js installable archive file from Node.js Downloads. At the time of writing this tutorial, following are the versions available on different OS.
Installation on UNIX/Linux/Mac OS X, and SunOS
Based on your OS architecture, download and extract the archive node-v6.3.1-osname.tar.gz into /tmp, and then finally move extracted files into /usr/local/nodejs directory.
$ cd /tmp $ wget http://nodejs.org/dist/v6.3.1/node-v6.3.1-linux-x64.tar.gz $ tar xvfz node-v6.3.1-linux-x64.tar.gz $ mkdir -p /usr/local/nodejs $ mv node-v6.3.1-linux-x64/* /usr/local/nodejs
Add /usr/local/nodejs/bin to the PATH environment variable.
Installation on Windows
Use the MSI file and follow the prompts to install the Node.js. By default, the installer uses the Node.js distribution in C:\Program Files\nodejs. The installer should set the C:\Program Files\nodejs\bin directory in window's PATH environment variable. Restart any open command prompts for the change to take effect.
