Overview

In this tutorial we are going to build a character voting app (inspired by Facemash and Hot or Not)
for EVE Online - a massively multiplayer online game.
Be sure to play this awesome soundtrack below to get yourself in the mood for this epicly long tutorial.

While listening to this soundtrack, imagine yourself mining asteroid belts in deep space while
keeping a lookout for pirates on the radar, researching propulsion system blueprints at the station’s facility,
manufacturing spaceship components for capital ships, placing buy & sell orders on the entirely
player-driven market where supply and demand govern the game economics, hauling trade goods from a remote solar system
in a massive freighter, flying blazingly fast interceptors with a microwarpdrive or powerful battleships armored to
the teeth, optimizing extraction efficiency of rare minerals from planets,
or fighting large-scale battles with thousands of players from multiple alliances. That is EVE Online .

Each player in EVE Online has a 3D avatar representing their character.
This app is designed for ranking those avatars. Anyway, your goal here is to learn about Node.js,
React and Flux, not EVE Online. But I will say this: “Having an interesting tutorial project is just as important,
if not more so, than the main subject of the tutorial”.
The only reason I built the original New Eden Faces app is to learn Backbone.js and the only reason I built the
TV Show Tracker app is so that I could learn AngularJS. To me, either one of these projects is far more
interesting than a simple todo app that everyone seems to be using these days.

One thing that I have learned — between screencasts, books and training videos,
nothing is more effective than building a small project that you are passionate about to learn a new technology.
