1. XMPP (whatsapp)
2. Websocket (Wechat)
3. WebRTC (hangouts, Google, facebook)

WebRTC Architectures

1. Peer to peer (1 to 1)
2. Peer to peer mesh (good for 2-5 people)
3. Using media servers (good for large no. of participants)

Servers

1. Signaling server ( good for LAN, where no NAT)
2. STUN server (used if NAT)
3. TURN server (use if NAT + firewall ie. cases where STUN fails)
4. Media Servers i) MCU ii) SFU

Some WebRTC Libraries/frameworks :

1. webRTC.io
2. simple-peer
3. easyRTC
4. rtc.io

What is used in this application?

1. WebRTC.io
2. peer to peer
3. public STUN server ('stun:stun1.l.google.com:19302')
4. firebase cloud store as a database
5. Firebase hosting
6. Material.io components for faster UI development

Still in progress :

1. P2P mesh implementation
2. RTCDataChannel Implementation

How to use :

1. clone the repository
2. create a project in firebase with firestore support
3. install firebase CLI in your system
4. Authenticate firebase CLI and navigate to your project
5. provide an alias fro your project
