All you have to do is install some libraries and they will make all the hard work for you. This will give the following goodies out of the box: As a first example, let's create a simple Web Socket endpoint that will reply the same message we send to it.We will need a new Django app - which we'll name "chat" so that we can use it later on.

You should be presented with the default Django screen, but you'll have a nice surprise if you try to use Web Sockets.Open your browser's console and type in the following Java Script code: // Create a new Web Socket ws = new Web Socket((window.location.protocol == 'http') ?Costs are separated into bands, with band five being the most expensive.To check exactly how much a number will cost, Skype recommends you check its website.Lately we see a constant switch towards real-time applications.
With the wide support for Web Sockets in recent browsers, more and more frameworks are giving us the ability to use them.

'ws://' : 'wss://' window.'/') // Make it show an alert when a message is received ws.onmessage = function(message) // Send a new message when the Web Socket opens ws.onopen = function() Hooray! That's a nice first step, but we're talking real-time chats here so let's move on to more advanced usage of sockets.
If you have any issues, you can always fast-forward to a working copy by typing Now that we have our simple echo server ready, the next big step is to create a group chat.
I'll leave this for another post though and I'll stick to our main theme: leveraging the power of Web Sockets to create a real-time application using Django Channels.
