Angular JS is one of the most popular and robust Frameworks available today to build SPA, Single Page Apps.
Here's a quick tutorial on how to quick install it on Ubuntu 14.04.
Get the latest nodejs and npm packages:
$sudo add-apt-repository ppa:chris-lea/node.js
$sudo apt-get update
Install node.js and its package manager npm:
$sudo apt-get install nodejs
Now, let's install Yeoman angular generator, which is a nice angular project generator, it will handle you project packages, as well as create the initial project structure, folders etc.
Visit the project page for more reference and documentation: https://github.com/yeoman/generator-angular
$sudo npm install -g generator-angular
Now that the generator is installed, we can start creating the structure for our angular.js app. Create a directory and create the app as following:
$mkdir webapp
$cd webapp/
$yo angular [app-name] --> running this command will generate the angular structure using Yeoman
Voila! now you can get started building awesome Angular Js apps on your Ubuntu system.
