## Transitioning from Django to AngularJS
This write-up is made for quickly let you understand AngularJS and able to participate in the development of Horizon in Openstack by using AngularJS.

### Prerequisite
Since AngularJS is actually a javascript library, you should know how to use JavaScript before you start the development. 
A great source to learn javascript is through [http://www.w3schools.com/js/](http://www.w3schools.com/js/). 

Besides the basic javascript syntax you should also understand the list of feature of javascript:
 -  Function Hoisting
 -  Callback Pattern
 -  Module Pattern
 -  Static Members

### Leanring Curve
Although AngularJS web app is entirely client-side application, 
but you can write AngularJS application without intergrating with a back end at all and still have a dynamic, responsive web app. 
It is learning curve is steeper than normal front-end technique. 

### Write-up Structure
Since this write-up aims to quickly let you know how to develop AngularJS with openstack, 
I will skip the detail of JavaScript and AngularJS (maybe I will create an independent pages for tutorial). 
But now let's install a devstack environment and testify the AngularJS portion. The write-up will follow this structure:
 -  Boot A VM in Cloud
 -  Install and initial devstack on the VM
 -  Running the devstack and be able to play with the dashboard
 -  Using Django to add a function to the dashboard 
 -  Instead of Django, using AngularJS to achieve that functionality
