Chat Project

The project is a Chat Web App, groups will be set randomly, you will use Firebase (a Remote Database based on AJAX Technology) and some CSS Preprocessors Less & Sass !

What you need, is what you already learn : HTML, CSS, Bootstrap, JS and jQUery !

First day, you will focus on the UX / UI Design of the app, and write some specifications (few mockup tools http://mashable.com/2012/06/07/mockup-tools/).

And finally you will have the total freedom to use plugins or framework (e.g.: Bootstrap or Foundation or Material Design Light).

Features

That's a chat, you have to let people discuss together, of course:

• First make one big global channel, and after allow other channels like private discussions ;
• Let users choose a pseudo and maybe defined an avatar (check Gravatar) ;
• Let people send Emoji Smiley, Links, Pictures, Youtube Videos, User Tags, etc.. (you will use REGEX) ;
• Make everything looks great (with a lot of CSS) and don't forget the app have to be responsive, think about how it will look on mobile devices!

Design

Here few advices and tricks to help you to work together on the same project code.

First work with whole team on global design, next split the team, between for example Backend and Frontend developers, the good idea is to use demo function, e.g.:

/* DEMO FUNCTIONS */

var sendMessage = function (message) {
    console.log("DEMO: sendMessage: " + message);
};

var retreiveMessages = function () {
    var messages = [
        { pseudo: "Roméo", message : "Ô Roméo ! Roméo ! pourquoi es-tu Roméo ? Renie ton père et abdique ton nom ; ou, si tu ne le veux pas, jure de m’aimer, et je ne serai plus une Capulet." },
        { pseudo: "Juliette", message : "Dois-je l’écouter encore ou lui répondre ?" }
    ];
    console.log("DEMO: retreiveMessages :" + messages);
    return messages;
};

The purpose is to start to code the interface and test using these functions and in the same time an other member of the team can work on the function to make them work with real data.

Here is the Javascript code example give on the official Firebase website:

// Create a connection to your Firebase database
var ref = new Firebase("https://<YOUR-FIREBASE-APP>.firebaseio.com");
// Save data
ref.set({ name: "Alex Wolfe" });
// Listen for realtime changes
ref.on("value", function(data) {
    var name = data.val().name;
    alert("My name is " + name);
});

Firebase have a realtime update design, so you can remplace the retreiveMessages function by just an updateConversation function we will update the content of the conversation and will be call in the ``ref.onmethod, and of coursesendMessage` will use `ref.set`.
