Description

WaveConnect is a JavaScript-based video conferencing application using WebRTC, featuring a mesh topology to facilitate seamless multi-peer connections.

Architecture

WebRTC

• A wants to connect to B.
• A creates an offer, which includes SDP, ICE candidates, and security options.
• A sends the offer to B using a chosen method.
• B creates an answer after processing A's offer.
• B sends the answer back to A.
• Connection is established.

(Additional information about NAT, STUN, TURN, ICE, and SDP is provided.)

1. NAT : Network Address Translation

2. STUN Server :

   • Session Traversal Utilities for NAT
   • Does nothing, just required to get our public address so that we can share it to communicate with others, since we are using NAT.

3. TURN Server :

   • Traversal Using Relays around NAT
   • Just a normal server that relays packets

4. ICE :

   • Interactive Connectivity Establishment : protocol
   • ICE collects all available candidates(ice candidates)
   • All collected addresses are then sent to remote peer via SDP.

5. SDP (Session Description Protocol)

   • A format that describes ice candidates, networking options,media options, securtiy options and a lot of other stuff
   • Not a protocol, its a format
   • The goal is to take the SDP generated by user and send it to the other party

6. Signalling

   • Send the SDP to other party via any of methods available like web sockets, HTTP request.

Installation and Setup

Prerequisites: node js, yarn/npm, git

1. Clone the repository:

git clone https://github.com/VenuChoudhary001/Wave.git

Change the directory to wave-server

cd wave-server
$ yarn dev

Setup Peer server

• Using npm

$ npm install peer -g

• Using yarn

$ yarn add peer -g

Running peer server

Open a new terminal window and run server

$ peerjs --port 9000

Change the directory to wave-client

Install dependencies

$ yarn

Add the socket port here

let socket = io(`${SOCKET_SERVER_URL}`);
const myPeer = new Peer(undefined, {
  host: "/",
  port: "9000",
});

Start client

$ yarn start
