InetSocket
Defined in: packages/node/src/net/inet-socket.ts:42
Base class for sockets whose transport is an IP connection.
On top of StreamSocket it exposes the endpoint accessors and the socket options that only make sense over IP, plus the connection-attempt and name-resolution events Node.js emits while dialling.
It is shared by TcpSocket and TlsSocket: both run over IP, but they establish their connection differently, so neither can be expressed as a subclass of the other.

Set Signature
Section titled “Set Signature”set timeout(
timeout):void
Defined in: packages/node/src/net/stream-socket.ts:173
Updates the inactivity timeout for the socket.
When set to a positive number, the socket emits a “timeout” event if no I/O
activity occurs within the given number of milliseconds. A value of 0 or
null disables the timeout entirely.
Parameters

Section titled “Methods”destroy()
Section titled “destroy()”destroy():
void
Defined in: packages/node/src/net/stream-socket.ts:262
Immediately destroys the underlying socket.
Pending I/O is discarded, the connection is closed and the socket transitions to a terminal state. Any registered “close” listeners will still be invoked.
Returns
Section titled “Returns”void
Inherited from
Section titled “Inherited from”end(
options?):Promise<void>
Defined in: packages/node/src/net/stream-socket.ts:204
Half-closes the socket, optionally waiting for a full close.
If waitForClose is omitted or false, the promise resolves once the
local side has finished sending data and the FIN has been queued. When
waitForClose is true, the promise resolves only after the remote side
has also closed and the “close” event has fired.
Parameters
Section titled “Parameters”options?
Section titled “options?”Optional settings for ending the socket.
Returns
Section titled “Returns”Promise<void>
A promise that resolves once the socket has ended.

K>(event,options?):Promise<TEvents[K]>
Defined in: packages/async/src/events/event-dispatcher-map-base.ts:45
Wait for the next occurrence of a specific event, optionally matching a predicate.
This is a convenience method that subscribes to the dispatcher, waits for the next event that matches the predicate (if provided), and then unsubscribes automatically.
Type Parameters
Section titled “Type Parameters”K extends string | number | symbol
Parameters
Section titled “Parameters”K
The event name to wait for.
options?
Section titled “options?”EventDispatcherWaitOptions<TEvents[K]>
Optional settings including predicate and abort signal.
Returns
Section titled “Returns”Promise<TEvents[K]>
A promise that resolves with the event arguments as an array.
Inherited from
Section titled “Inherited from”write()
Section titled “write()”write(
data):Promise<void>
Defined in: packages/node/src/net/stream-socket.ts:241
Writes data to the socket and resolves once that chunk has been flushed.
Awaiting the result is what applies backpressure: the promise settles on the chunk’s own flush rather than on the whole buffer draining, so a producer that awaits each write never outruns the socket. A caller that does not await is free to queue without bound.
Parameters
Section titled “Parameters”Uint8Array
The data to write.
Returns
Section titled “Returns”Promise<void>
Throws
Section titled “Throws”When the socket errors or is destroyed before the chunk flushes.

Creates a new StreamSocket instance.
Parameters
Section titled “Parameters”options?
Section titled “options?”SocketConstructorOpts
Options for creating the underlying Node.js socket.
Returns
Section titled “Returns”A new StreamSocket instance.
