Our project uses gulp to:

• combine all individual modules into a single file
• transpile ES6 code to ES5 with babel.js
• minimize JS and CSS code
• generate source maps
• add vendor prefixer to the css
• provide a server with live-reload

# install gulp globally so you can run it from the command line
npm install -g gulp-cli

# install all dependencies
npm install

# run gulp to start the livereload server on http://localhost:8080 
gulp

NOTE: For Node.js versions below 0.12, you need to install an ES6-style Promise Polyfill (in case you receive a "Promise is undefined" error). To run with Promise, use:

npm install es6-promise

Then add the following line at the top of your gulpfile.babel.js:

var Promise = require ('es6-promise').Promise;

To check your Node.js version, use:

node --version

Note: Although no linter is added as of yet, the code closely follows the conventions from Airbnb's ECMAScript 6 Javascript style guide

The app entry point is js/index.js. It performs the initial application setup (loads the app when jQuery loads, loads the initial data from the server etc.)

The main application object is js/app/index.js, which holds the necessary global application state flags and application level methods. It is extended once the app loads in index.js with the contents of app/constructor and app/cache. This means that from here on now, any file that does require(/* path to js/app */) is getting that populated object since calls to require are cached.

The js/dom directory holds all the code interacting with the DOM (go figure 😜). The code is split into:

• "static" methods that are used everywhere (such as adding algorithm info to the DOM) and,
• setup code which is called within the app/constructor, after the DOM is ready, to initialize all the elements with their contents and listeners.

The js/editor directory holds the code to create and execute code in the ace editor.

The js/module directory holds all the tracers and the random-data-creators. All the modules are exported together and then "required" inside the entry point js/index.js where they are attached to the global window object so eval can use them when executing code in the code editor.

The js/server directory holds all the code to load data from the server and utilizes promises from RSVP.js. In js/server/ajax are some helper methods to make requesting from the server a little easier. The main method is js/server/ajax/request.js that is used by all other methods to call $.ajax with certain options and set/reset the global isLoading flag for every request.

The js/tracer_manager directory holds the manager of tracers, which controls all the present tracers simultaneously.

The utils directory holds a few helper methods that are used everywhere such as building the strings for algorithm and file directories.
