Make sure you have installed all these prerequisites on your development machine.

• Node.js - Download & Install Node.js and the npm package manager, if you encounter any problems, you can also use this Github Gist to install Node.js.

• Bower - You're going to use the Bower Package Manager to manage your front-end packages, in order to install it make sure you've installed Node.js and npm, then install bower globally using npm:

$ npm install -g bower

• Grunt - You're going to use the Grunt Task Runner to automate your development process, in order to install it make sure you've installed Node.js and npm, then install grunt globally using npm:

$ sudo npm install -g grunt-cli

To install Node.js dependencies you're going to use npm again, in the application folder run this in the command-line:

$ npm install

To install Node.js dependencies you're going to use npm again, in the application folder run this in the command-line:

$ bower install

After the install process is over, you'll be able to run your application using Grunt, just run grunt default task:

$ grunt or $ node server.js

Your application should run on the 3000 port so in your browser just go to http://localhost:3000

That's it! your application should be running by now.

Key Design Notes

FOLDER ORGANIZATION : When it comes to marriying two MVC technologies (Angular and Express) organizaing the folders by itself is a challenge. There is no defacto standard , but i particularly liked what MEAN.js did, taking a modular approach. The modules in 'public' (angular) are all independent having their own routs,views,controlles etc. Clear seperation of concenrs.

DATA PROVIDER: Angular reaches out to Node server in the background for data.The interaction with the spotify API is done thorough a node wrapper spotify-web-api-node which uses restler and is a nice promise based interface. The usage of Node is to show case my skill there and also it gives additional control over what goes out to the UI
