The number of milliseconds of inactivity a server needs to wait for additional incoming data, after it has finished writing the last response, before a socket will be destroyed. If the server receives new data before the keep-alive timeout has fired, it will reset the regular inactivity timeout, i.e., server.timeout.

listening

val listening: Boolean

Indicates whether or not the server is listening for connections.

listeningEvent

open override val listeningEvent: EventInstance<JsTuple>

maxConnections

var maxConnections: Double

Set this property to reject connections when the server's connection count gets high.

maxHeadersCount

var maxHeadersCount: Double?

Limits maximum incoming headers count. If set to 0, no limit will be applied.

maxRequestsPerSocket

var maxRequestsPerSocket: Double?

The maximum number of requests socket can handle before closing keep alive connection.

requestEvent

open val requestEvent: EventInstance<JsTuple2<Request, Response>>

requestTimeout

var requestTimeout: Double

Sets the timeout value in milliseconds for receiving the entire request from the client.

timeout

var timeout: Double

The number of milliseconds of inactivity before a socket is presumed to have timed out.

upgradeEvent

open val upgradeEvent: EventInstance<JsTuple3<Request, Duplex, Buffer>>

Functions

addListener

fun addListener(type: EventType, listener: EventListener)

Alias for emitter.on(eventName, listener).

open override fun addListener(event: String, listener: Function<Unit>)

events.EventEmitter

address

fun address(): Any?

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' }.

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.

closeAllConnections

open fun closeAllConnections()

Closes all connections connected to this server.

closeIdleConnections

open fun closeIdleConnections()

Closes all connections connected to this server which are not sending a request or waiting for a response.

emit

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

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

eventNames

fun eventNames(): Array<EventType>

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

getConnections

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

fun getMaxListeners(): Double

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

listen

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

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

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

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

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

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

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

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

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

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

fun listeners(type: EventType): Array<EventListener>

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

off

fun off(type: EventType, listener: EventListener)

Alias for emitter.removeListener().

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

once

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

prependListener

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

prependOnceListener

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

rawListeners

fun rawListeners(type: EventType): Array<EventListener>

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

ref

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

fun removeAllListeners(type: EventType = definedExternally)

Removes all listeners, or those of the specified eventName.

removeListener

fun removeListener(type: EventType, listener: EventListener)

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

setMaxListeners

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.

setTimeout

fun setTimeout(callback: () -> Unit)

fun setTimeout(msecs: Number = definedExternally, callback: () -> Unit = definedExternally)

Sets the timeout value for sockets, and emits a 'timeout' event on the Server object, passing the socket as an argument, if a timeout occurs.

unref

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.
