Overview of this book

XMPP (eXtensible Messaging and Presence Protocol) is a messaging protocol that enables communication between two or more devices via the Internet. With this book, developers will learn about the fundamentals of XMPP, be able to work with the core functionality both server-side and in the browser, as well as starting to explore several of the protocol extensions. You will not only have a solid grasp of XMPP and how it works, but will also be able to use the protocol to build real-world applications that utilize the power of XMPP. By the end of this book, you will know more about networking applications in general, and have a good understanding of how to extend XMPP, as well as using it in sample applications.

The first task we'll need to complete is to get logged in to our server. Let's create a script file in our project at public/scripts/xmpp.js, where we can start handling the client side features. To handle login, we'll listen for a client on the login button:

socket.on('xmpp.connection', connected) 
var connected = function(details) { 
  $('p.connection-status').html('Online') 
} 
socket.on('xmpp.error', errorReceived) 
var errorReceived = function(error) { 
  if ('auth' === error.type) { 
    return alert('Authentication failed') 
  } 
} 
$('button[name="login"]').click(function() { 
  var jid = $('input[name="jid"]').val() 
  var password = $('input[name="password"]').val() 
     if (!jid || !password) { 
       return alert('Please enter connection details') 
     } 
     var options = { jid: jid, password: password } 
     socket.send('xmpp.login', options) 
})
