peer to peer ， based on webrtc

Be sure to use HTTPS protocol or localhost, otherwise the demo will not work properly

github

Simple WebRTC video, voice, and data channels;

The peer2peerRTC is separated from websocket; you can customize your signaling service.

features

• supports video/voice streams
• supports data channel

usage

you can install with npm ,or import like demo

npm install gun-p2prtc

This example create two peers in separated web page.

In a real-world application, The sender and receiver Peer instances would exist in separate browsers. A "signaling server" (usually implemented with websockets) would be used to exchange signaling data between the two browsers until a peer-to-peer connection is established.

api

new P2pRtc(option)

If option is specified, then the default options (shown below) will be overridden.

const option = {
    rtcConfiguration: null,
    initiator: false,
    offerOptions: {offerToReceiveAudio: 1, offerToReceiveVideo: 1},
    answerOptions: {},
    constraints: {audio: true, video: true},
    localStream: null
}
const peer = new P2pRtc(option);

The options do the following:

• rtcConfiguration: custom webrtc configuration (used by RTCPeerConnection constructor);
• initiator: set to true if this is the initiating peer
• offerOptions: custom offer options (used by createOffer method)
• answerOptions: custom answer options (used by createAnswer method)
• constraints: custom stream options (used by getUserMedia method)
• localStream: if video/voice is desired, pass stream returned from getUserMedia

peer.signal(data)

Call this method whenever the remote peer SDP message received.

peer.mute(kind)

string <video | audio>. close local audio or close local video

peer.unmute(kind)

string <video | audio>. open local audio or open local video, and remote peer will received.

peer.getStats()

provide statistics about either the overall connection

peer.send(text)

send text over datachannel

peer.leave()

peer leave.

events

localStream

peer.addEventListener('localStream', data => {
    localVideo.srcObject = data.stream
})

offer

peer.addEventListener('offer', offer => {
    ws.send(JSON.stringify(offer))
})

answer

peer.addEventListener('answer', answer => {
    ws.send(JSON.stringify(answer))
})

icecandidate

peer.addEventListener('icecandidate', event => {
    if (event.candidate) ws.send(JSON.stringify({type: 'icecandidate', candidate: event.candidate}))
})

remoteStream

 peer.addEventListener('remoteStream', event => {
    remoteVideo.srcObject = event.remoteStream;
})

dataChannel-ready

peer.addEventListener('dataChannel-ready', () => {
    // now you can use dataChannel send message
});

message

peer.addEventListener('message', (event) => {
    console.log('receive text => ', event.data)
});
