Webrtc, & web socket based streaming live video streaming and chatting platform. Written in Node, Typescript, and Javascript!

Live Streaming!!

• Welcome to my implementation of live streaming along with real time chat. I'm going to make a live streaming platform that will supoort streaming from a single user...aka ME, but will let anyone view it, and interact in a chatroom while I stream a video!

Architecture

Video Streaming

• Built with Peerjs for webrtc and socketio for websocket.
• Admin publishing client waits for users to join.
• When users join they emit an event containing their peerjs ID via websocket, which is relayed to Admin publishing client.
• The admin publishing client upon recieving the viewer's peerjs client initiates a peer to peer connection to the viewer, and begins streaming audio and video data across the network using webrtc.

Live Chat

• Purely built over websockets. The live chat does not utilize webrtc.
• Clients emit messages that are then stored for running a backfill when later users join, this backfill is purged ever 10 seconds when thread size exceeds over 400 messages.
• Server broadcasts messages, which is a monitored event that a client will respond to by altering it's own state.

Capabilities

• Authenticated route to access to upload permissions
• Once logged in I can begin streaming
• A random user can hit a url to view a live stream session.
• live stream sessions will be visible only when I am streaming.
• live stream will be presented with a live chat room!

Technologies

• Node js, Typescript, Javascript, HTML, CSS, EJS, WebRtc (peer), Webscokets (Socket.io)

How to run this?

• Have npm installed!
• npm i -g peerjs
• Create and set your local env variables: JWT_KEY, USERNAME, PASSWORD
• npm i
• npm run start.
• Access localhost:3000/admin/signin to login and stream
• Access localhost:3000/ to view livestream and chat!
