peerjs-server.net

ASP.NET Core Server for the PeerJS library which simplifies peer-to-peer data, video, and audio calls.

To broker connections, PeerJS connects to a PeerServer. Note that no peer-to-peer data goes through the server; The server acts only as a connection broker.

This is an ASP.NET Core port of the Node.js implementation.

Server setup

public void ConfigureServices(IServiceCollection services)
{
    ...
    // register PeerJs Server dependencies
    services.AddPeerJsServer();
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    ...
    // enable PeerJs Server middleware
    app.UsePeerJsServer();        
}

That's it, we're good to go.

Client library setup

The repository also contains a demo project.

However, we can read more about the library usage on the official website. Here's a quick sample:

Add the PeerJS client library to your webpage:

<script src="https://unpkg.com/peerjs@1.0.0/dist/peerjs.min.js"></script>

Create the Peer object:

const peer = new Peer(randomId, {
    host: 'localhost',
    port: 44329,
    path: '/'
});

Start a call:

// Call a peer, providing our mediaStream
navigator.mediaDevices
    .getUserMedia({
        audio: true,
        video: true
    })
    .then(function (mediaStream) {
        myVideo.srcObject = mediaStream;
        // Call a peer, providing our mediaStream
        var call = peer.call('dest-peer-id', mediaStream);
    });

Answer call:

peer.on('call', function(call) {
  // Answer the call, providing our mediaStream
  call.answer(mediaStream);
});

Use the stream:

call.on('stream', function(stream) {
  // `stream` is the MediaStream of the remote peer.
  // Here you'd add it to an HTML video/canvas element.
});
