<h1>hello, then</h1>

<p>The functions <code>hello.api</code>, <code>hello.login</code> and <code>hello.logout</code> return a <a href="http://promisesaplus.com/">Promises/A+ 1.1.1</a> compliant then method.</p>

<h2>Example hello.api().then()</h2>
<p>This example shows how to use Promises to act on the response from hello.login and hello.api calls.</p>

<button id='google' onclick="login('google');">google profile</button>

<script class="pre">
function login(network){
	// Make a login call and handle the response using promises
	var hi = hello(network);
	hi.login().then(function(){
		console.log('fullfilled', 'making api call');
		// Reurn another promise to get the users profile.
		return 	hi.api( 'me' );
	}).then(function(p){
		// Print it to console.
		console.log('hello.api(me) was fullfilled', p);
		return p;
	}).then(function(p){
		// Insert it into thumbnail
		document.getElementById(network).innerHTML = "<img src='"+ p.thumbnail + "' width=24/>Connected to "+ network +" as " + p.name;
	}).then(null, function(e){
		// Uh oh
		console.error(e);
	});
}
</script>


<h2>Promise.all</h2>

<p><code>Promise.all</code> is not native in IE yet so here's a shim</p>
<script src="http://s3.amazonaws.com/es6-promises/promise-1.0.0.min.js" class="pre"></script>


<h3>Example Promise.all</h3>


<p>
<button id='google' onclick="friendsAndContacts('google');">google friends and contacts</button>

<pre id="friends" placeholder="Please click the button above to get friends and contacts here."></pre>

<script class="pre">
function friendsAndContacts(network){
	// Make a login call and handle the response using promises
	hello(network).login({scope:'friends'}).then(function(){
		console.log('fullfilled', 'making api call');
		// Reurn another promise to get the users profile.
		return Promise.all([
			hello( network ).api( 'me/friends' ),
			hello( network ).api( 'me/contacts' )
		]);
	}).then(function(all){

		// Build a list of friends
		var a = [];
		for(var i=0;i<all.length;i++){
			for(var j=0;j<all[i].data.length;j++){
				a.push(all[i].data[j].name);
			}
		}
		document.getElementById('friends').innerHTML = a.join(',');

	}, function(e){
		// Uh oh
		console.error(e);
	});
}
</script>


<p>Initiate app</p>
<script class="pre">
hello.init( {
	google : CLIENT_IDS.google
},
{
	redirect_uri : '../redirect.html'
});
</script>
