Building Nodejs server on ubuntu

Building Nodejs server on ubuntu

Node.js is a Javascript platform for server-side programming that allows users to build network applications quickly. 

Building nodejs server in ubuntu is fairly simple and easy. With few commands you can make a nodejs server up and running in not time.
Nodejs generally runs of port 3000 but that is not mandatory, you can use any other port you want to make your server more customised.

There are few path, you can follow to get your Nodejs up and running on Ubuntu 14.04

======================
Distro-Stable Version
======================
In order to get this version, we just have to use the apt package manager. We should refresh our local package index prior and then install from the repositories:

sudo apt-get update
sudo apt-get install nodejs

 In many cases, you'll also want to also install npm, which is the Node.js package manager. It will allow you to easily install modules and packages to use with Nodejs You can do this by typing:

sudo apt-get install npm

==================
Using a PPA
==================
you need to install the PPA in order to get access to its contents:

curl -sL https://deb.nodesource.com/setup | sudo bash -

After running the setup script from nodesource, you can install the Node.js package in the same way that you did above:

sudo apt-get install nodejs

In order for some npm packages to work (such as those that require building from source), you will need to install the build-essentials package:

sudo apt-get install build-essential

====================
Using NVM
====================

NVM stand for  Node.js version manager. The nvm script will leverage these tools to build the necessary components:

sudo apt-get update
sudo apt-get install build-essential libssl-dev

The version number may be different

curl https://raw.githubusercontent.com/creationix/nvm/v0.16.1/install.sh | sh

To find out the versions of Node.js that are available for installation, you can type:

nvm ls-remote

You can have npm install packages to the Node.js project's ./node_modules directory by using the normal format:

npm install express

If you'd like to install it globally (available to the other projects using the same Node.js version), you can add the -g flag:

npm install -g express

Last but not the least, Anytime to get help type:

nvm help
