/* This shows how you can authenticate users and store user data in Firebase 
using Firebase Simple Login with Twitter. The corresponding security rules for 
this app are available in this gist: https://gist.github.com/sararob/8694d5b4111e4ed31cec */

// Define Firebase references
var ref = new Firebase("<your-firebase>.firebaseio.com/");
var usersRef = ref.child("users");
var currentUser = null; //we'll use this to see if a user is currently logged in

// Call an 'auth' function when a user clicks a login button (this example uses twitter)
$('#login').on("click", function () {
	auth.login('twitter');
});
	
// Authenticate users and store each user in Firebase by their Twitter UID
var auth = new FirebaseSimpleLogin(ref, function (error, user) {
  if (error) {
    console.log(error);
  } else if (user) {
	  usersRef.child(user.uid).set({pic: user.thirdPartyUserData.profile_image_url, username: user.username});
	  currentUser = user;
  } else {
    //user is logged out
  }
});

// When a user adds a message, add the message data to Firebase
$('#message-submit').on('click', function () {
	if (currentUser != null) {
		var message = $('#msgInput').val();

		//Send the message to Firebase
		messagesRef.push({user: currentUser.uid, username: currentUser.username, message: message});
	} else {
		alert('You must login with Twitter to post!');
	}
});
