Forward request to ws client and wait for response Express

Question

I\'m trying to build an endpoint that will receive a request, emit the request data to a WebSocket client, wait for an event, then send back the response using express + soc

Answer 1

Please note that:

socket.on('res', function (data) {
    res.status(200).json(data);
});

Is being called each time a socket is sending a response, thus showing the above error. You should unbind the listener inside the callback function.
