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

Try this while sending data to client: - socket is my current web socket object.It overwrites the default >WebSocket.js class condition that throws "not-opened error".

if (socket.readyState != socket.OPEN) {
    console.error('Client state is ' + socket.readyState);
    //or any message you want
} else {
    socket.send(JSON.stringify(object)); //send data to client
}
