Contents

• ./go-libp2p-host/

Example of a Go p2p listener using the WebRTC transport.

• ./p2p-react/

Example of a React web app with a p2p dialer using the WebRTC transport.

Instructions

1. Build and run the service

    $ cd go-libp2p-host
    $ go build
    $ ./go-libp2p-host

2. Collect the service's multiaddr The output of go-libp2p-host should be something like:

   p2p addr: /ip4/172.29.128.142/udp/62499/webrtc/certhash/uEiBec5Z32kurAEP29bQ-B20RdhokNzjujfwBh79xh0b6mw/p2p/12D3KooWH3sWbHfTsqHMpV1zWAB2me2H4yXABwxRCupLNwkSfsgD press Ctrl+C to quit
