Peer to peer video calling

It's built into your browser already 😮

Mon, Jan 11, 2021

My mind was blown today when I found out about WebRTC and how it can enable video calls directly from my browser to yours without any data going through another server 🤯. I’m aware that I’m probably very late to the party on this one, but I was particularly excited by the PeerJS library that helped me get started really quickly.

PeerJS wraps the browser’s WebRTC implementation to provide a complete, configurable, and easy-to-use peer-to-peer connection API. Equipped with nothing but an ID, a peer can create a P2P data or media stream connection to a remote peer.

I’ve had a lot of fun today building this little prototype and trying it out with friends:

and because I’ve deployed the code as a Glitch app you can remix it to your hearts content.
