Install node.js and npm

Node.js, often referred to as node, is a simple webserver, which is programmed in Javascript.

To see which version, if any, of node.js and npm you have installed use

node –version
npm –version

The version of node.js in the ubuntu repositories is quite old.

To ensure you get version 6 do

curl -sL | sudo -E bash –

which configures apt-get to use nodesource.

Installing node.js and making a symlink to define ‘node’ is now as simple as:

sudo apt-get –yes install nodejs

The script does the above to install node.
