Realtime Chat Widget using Pusher

This sample shows how to create a Realtime Chat Widget with a PHP, Ruby or Node.js backend.

Demo

Here is a live version of the chat widget in action.

Tutorial

We've put together a tutorial on how to get up and running with the widget.

src

/nodejs

The server code required to run the example using Node.js.

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

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

You can then get started by:

cd src/nodejs
npm install
node app.js

And navigating to http://localhost:4567 to see the side-by-side example or http://localhost:4567/chat.html to see the standalone example.

/php

The server code required to use the widget with a PHP back-end. Update the src/chat.html file to your PUSHER_APP_KEY:

var pusher = new Pusher("CHANGE_KEY")

Then, set up the PHP back-end:

cd src/php
composer install
cd ..
PHP -s localhost:8080

And navigating to http://localhost:8080/ to see the side-by-side example or http://localhost:8080/chat.html to see the standalone example.

/ruby-sinatra

The server code required to run the example using 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("CHANGE_KEY")
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

And navigating to http://localhost:4567/ to see the side-by-side example or http://localhost:4567/chat.html to see the standalone example.
