Demo

https://github.com/berty/weshnet/assets/7917064/609fcb18-6b7d-4c80-bc6d-d68fdbdd3eda

Usage

cd wasm && make serve the navigate to "localhost:4242" in two browsers

Caveats

• The group invitation is printed in the console only, you can then paste it in the input next to "join" button and click it
• You need to dial the other peer manually via helia.libp2p.dial(Libp2PPeerId.peerIdFromString("<peerId-of-other-browser>")) in the browser console
• It only got it to work between a firefox and a chrome, not 2 chrome or 2 ff, and only once bidirectionally
