I want to create a listener on a socket. Then once the listener has been executed, I want the listener to stop listening. I used this SO:
socket.io Removing specific listener
But I cannot figure out how to have a listener destroy itself. This is what I am thinking:
var ListenEventFunc = function() {
/* Do some important stuff */
socket.removeListener('ListenEvent',ListenEventFunc);
}
socket.on('ListenEvent',ListenEventFunc);
What is the correct/best way to do this? Is there anyway I can use the this
keyword to specify the function.

You can use this:
socket.once('ListenEvent', ListenEventFunc);
This works because Socket
inherits from EventEmitter
. This doesn't seem to be documented, but the code references it.
