node.js websocket crashes when client disconnect

Question

I am very new to NodeJS and Websockets, but i am trying to play with it.

What i do is read incoming datas from Serial port, then send these dat

Answer 1

I was having this same issue. Turned out I was attempting to send events to sockets that were in the "closing" state. Checking that each socket was specifically open before broadcasting a message fixed it for me:

    function sendAll(data){
        for(var i = 0; i < clients.length; i++){
            if(this.clients[i].readyState != this.clients[0].OPEN){
                console.error('Client state is ' + this.clients[i].readyState);
            }
            else{
                this.clients[i].send(data);
            }
        }
    }
