WebRTC and Ratchet Chat Application

A one-to-one text, audio and video chat application built with webRTC and Ratchet.

Requirements

• PHP >= 5.4
• Every other required files are included or referenced as the case may be

Getting Started

To test this app on your local server:

• The Ratchet server must be ON. This can be achived by navigating to webrtc-ratchet-chat-app/ws/bin from your cli and run php server.php
• Run the app from your browser at: http://localhost/webrtc-ratchet-chat-app/
• Create and enter a room
• Enter the room from two different browsers (using the same link) and test by sending text chats. This can be done on the same device.
• The audio and video call is best tested on two different devices. This will require more configuration
• Open webrtc-ratchet-chat-app/js/comm.js and change this line const wsChat = new WebSocket("ws://localhost:8080/comm"); to const wsChat = new WebSocket("ws://YOUR_SERVER_IP:8080/comm");
• Open webrtc-ratchet-chat-app/ws/bin/server.php and add your server ip address to $allowed_origins array, then replace the localhost in $app = new Ratchet\App('localhost', 8080, '0.0.0.0'); with your ip address
• Blam! Good to go. Navigate to YOUR_IP_ADDRESS/webrtc-ratchet-chat-app on your browser on two different devices to start chatting
• Works best on Chrome, Firefox and the latest versions of Opera desktop browser.

#Note To host this online, you'll need to set a few things up:

• Create Ratchet as a service so it can run persistently on your server. Check the file ratchet_as_a_service.txt for the guide on how to do this on CentOS7
• If on SSL, Ratchet won't work unless you make some changes on your server. This answer on Stack Overflow should be helpful.
