simple-peer on.("signal") event repeats many times

Question

I'm using simple-peer to create a small video calling app using NodeJS, SocketIO and Angular

I'm trying to implement full-mesh here. I have a peer initialtor which will initiate the signal on loop.

My code is as below.

const peer = new SimplePeer({
    initiator: true,
    trickle: false,
    stream,
});

peer.on("signal", signal => {
    console.log(userToSignal, "signal-callerID");
    this.peerService.emit("sending signal", { userToSignal, callerID, signal })
})

This function will be in loop. when a new user conenct, It'll send the signal to that user, My problem is, peer.on("signal", signal => event repeats itself even if there is only 1 user conencted, its making likle 11 requests on 1 peer create. whats the issue here and how can i fix it?

I'm refering to this code and trying to implement this in angular.

Answer 1

I got the same issue. Just try with simple peer library version 9.6.2. It works!!!!!

Answer 2

That is normal behavior, an offer and ice candidates. If you want just a single message set the trickle option to false as described here. Note that this will incur additional latency in establishing the connection.

Answer 3

Add this to ur client. I made Express webRTC app and find out that too much peers adding to my clients responsive peers array. So find out this code in Issues. Btw try this.

socketRef.current.on("user joined", payload => {
        const item = peersRef.current.find(p => p.peerID === payload.callerID);
        if(!item) {
          const peer = addPeer(payload.signal, payload.callerID, stream);
          peersRef.current.push({
            peerID: payload.callerID,
            peer,
          })
          peers.push(peer);
        }
});

It worked for me. After resignal, peers wont add to ur array and u'll got ur video stream from another peer.
