Returns the bound address, the address family name, and port of the server as reported by the operating system if listening on an IP socket (useful to find which port was assigned when getting an OS-assigned address):{ port: 12346, family: 'IPv4', address: '127.0.0.1' }.

external fun close(callback: (JsError?) -> Unit = definedExternally)

Stops the server from accepting new connections and keeps existing connections. This function is asynchronous, the server is finally closed when all connections are ended and the server emits a 'close' event. The optional callback will be called once the 'close' event occurs. Unlike that event, it will be called with an Error as its only argument if the server was not open when it was closed.

emit

external fun emit(type: EventType, vararg args: Any?): Boolean

Synchronously calls each of the listeners registered for the event named eventName, in the order they were registered, passing the supplied arguments to each.

open external fun emit(event: Symbol, vararg args: Any?): Boolean

open external fun emit(event: String, vararg args: Any?): Boolean

eventNames

external fun eventNames(): ReadonlyArray<EventType>

Returns an array listing the events for which the emitter has registered listeners. The values in the array are strings or Symbols.

getConnections

external fun getConnections(cb: (JsError?, count: Double) -> Unit)

Asynchronously get the number of concurrent connections on the server. Works when sockets were sent to forks.

getMaxListeners

external fun getMaxListeners(): Double

Returns the current max listener value for the EventEmitter which is either set by emitter.setMaxListeners(n) or defaults to {@link EventEmitter.defaultMaxListeners}.

listen

external fun listen(handle: Any?, listeningListener: () -> Unit = definedExternally)

external fun listen(port: Number = definedExternally, listeningListener: () -> Unit = definedExternally)

external fun listen(path: String, listeningListener: () -> Unit = definedExternally)

external fun listen(options: ListenOptions, listeningListener: () -> Unit = definedExternally)

external fun listen(handle: Any?, backlog: Number = definedExternally, listeningListener: () -> Unit = definedExternally)

external fun listen(port: Number = definedExternally, backlog: Number = definedExternally, listeningListener: () -> Unit = definedExternally)

external fun listen(port: Number = definedExternally, hostname: String = definedExternally, listeningListener: () -> Unit = definedExternally)

external fun listen(path: String, backlog: Number = definedExternally, listeningListener: () -> Unit = definedExternally)

external fun listen(port: Number = definedExternally, hostname: String = definedExternally, backlog: Number = definedExternally, listeningListener: () -> Unit = definedExternally)

Start a server listening for connections. A net.Server can be a TCP or an IPC server depending on what it listens to.

listenerCount

external fun listenerCount(type: EventType, listener: EventListener = definedExternally): Double

Returns the number of listeners listening for the event named eventName. If listener is provided, it will return how many times the listener is found in the list of the listeners of the event.

listeners

external fun listeners(type: EventType): ReadonlyArray<EventListener>

Returns a copy of the array of listeners for the event named eventName.

off

external fun off(type: EventType, listener: EventListener)

Alias for emitter.removeListener().

external fun on(type: EventType, listener: EventListener)

Adds the listener function to the end of the listeners array for the event named eventName. No checks are made to see if the listener has already been added. Multiple calls passing the same combination of eventName and listener will result in the listener being added, and called, multiple times.

open external fun on(event: String, listener: Function<Unit>)

once

external fun once(type: EventType, listener: EventListener)

Adds a one-time listener function for the event named eventName. The next time eventName is triggered, this listener is removed and then invoked.

open external fun once(event: String, listener: Function<Unit>)

prependListener

external fun prependListener(type: EventType, listener: EventListener)

Adds the listener function to the beginning of the listeners array for the event named eventName. No checks are made to see if the listener has already been added. Multiple calls passing the same combination of eventName and listener will result in the listener being added, and called, multiple times.

open external fun prependListener(event: String, listener: Function<Unit>)

prependOnceListener

external fun prependOnceListener(type: EventType, listener: EventListener)

Adds a one-timelistener function for the event named eventName to the beginning of the listeners array. The next time eventName is triggered, this listener is removed, and then invoked.

open external fun prependOnceListener(event: String, listener: Function<Unit>)

rawListeners

external fun rawListeners(type: EventType): ReadonlyArray<EventListener>

Returns a copy of the array of listeners for the event named eventName, including any wrappers (such as those created by .once()).

ref

external fun ref()

Opposite of unref(), calling ref() on a previously unrefed server will not let the program exit if it's the only server left (the default behavior). If the server is refed calling ref() again will have no effect.

removeAllListeners

external fun removeAllListeners(type: EventType = definedExternally)

Removes all listeners, or those of the specified eventName.

removeListener

external fun removeListener(type: EventType, listener: EventListener)

Removes the specified listener from the listener array for the event named eventName.

setMaxListeners

external fun setMaxListeners(n: Number)

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. The emitter.setMaxListeners() method allows the limit to be modified for this specific EventEmitter instance. The value can be set to Infinity (or 0) to indicate an unlimited number of listeners.

unref

external fun unref()

Calling unref() on a server will allow the program to exit if this is the only active server in the event system. If the server is already unrefed callingunref() again will have no effect.
