emitter.setMaxListeners(n)
By default EventEmitters will print a warning if more than 10
listeners are added for a particular event. This is a useful default that helps finding memory leaks. Obviously, not all events should be limited to just 10 listeners. The emitter.setMaxListeners()
method allows the limit to be modified for this specific EventEmitter
instance. The value can be set to Infinity
(or 0
) for to indicate an unlimited number of listeners.
Returns a reference to the EventEmitter
so calls can be chained.
