#webRTC-chat
WebRTC-chat is a Video/Text chat implemented using a new exciting web technology called WebRTC. WebRTC provides a means of installing a P2P connection between two browsers. That is, the browser becomes a peer in P2P network. This allows us developers to implement a kind of web application that a fews years ago wouldn't had been possible to imagine.
The only goal of this project is to study and understand in depth the characteristic and possibility of this new technology. I want to implement a chat service with the following features :
- Optional Video Chat with different video qualities : QVGA, VGA, HD. ( done )
- Optional Audio ( working )
- Optional DataConnection
- Text Chat
- File sharing
- A mesh network is used to connect peers. ( done )
- Session restoring
- Move to HTTPS and WSS
- Bandwidth adaptetion
- More then 2 users are allowed to connect at same time. In fact, there is no limit for the number ( done )
of users but a mesh network does not scale well and after 4 or 5 users the application is
unusable
A deployed version of the application can be found at : http://webrtc-chat-experiment.herokuapp.com/
##How to use it
Using this app is really easy, you just need to go to browse to main page and automatically a chat is created. To invite someone else in the room, you need just to share the url of the page.
##Signalling service The signalling service is implemented using node.js and socket. ( fully implemented and tested )
##Techonology THe front end is implemented using Backbone.js. The base app model is built around the single peer connections object. When a new peer connection is created is added to a BackBone collection which mantains a list of all peer Connection open in the web page.
Express and jade are used to dinamically generate web pages.
There is no need for a db as I don't keep any information regarding peer sessions in the back-end.
##Note The project is under heavy development.
- Move to SSH and WSS
- Data Channel ( to implement entirely)
- Implement a better control over the number of peers per room
