The first version of this sample shows how to create a Realtime Chat Widget with a PHP backend. Later versions will demonstrate how to achieve this using other backend technologies.

You can see a live version of the chat widget in action here: http://pusher-realtime-chat-widget.phpfogapp.com/src/

A tutorial of how to get up and running with the widget an be found here: http://pusher.com/tutorials/realtime_chat_widget

The server code required to use the widget with a PHP back-end. The src/chat.html file is set up to us the PHP back-end.

The server code required to run the example under Sinatra.

The src/chat.html file will need to be updated so that the PusherChatWidget talks to the sinatra app. This means providing a chatEndPoint setting to point to /chat as follows:

var pusher = new Pusher('49e26cb8e9dde3dfc009')
var chatWidget = new PusherChatWidget(pusher, {
  appendTo: '#pusher_chat_widget',
  chatEndPoint: '/chat'
});

You can then get started by:

cd src/ruby-sinatra
bundle install
bundle exec ruby -rubygems chat.rb
