BaseAgent<OptionsType, StateType, ResultType>

BaseAgent is the base class for all agents. It implements the basic agent lifecycle and convenience functions. It also implements thread management. This class is not directly usable and will throw unimplemented. To implement a custom agent, extend this class (see initialize, finalize and step methods).

captureRejectionSymbol

static readonly captureRejectionSymbol: typeof captureRejectionSymbol;

Value: Symbol.for('nodejs.rejection')

See how to write a custom rejection handler.

captureRejections

static captureRejections: boolean;

Value: boolean

Change the default captureRejections option on all new EventEmitter objects.

Since

v13.4.0, v12.16.0

Source

node_modules/@types/node/events.d.ts:409

defaultMaxListeners

static defaultMaxListeners: number;

By default, a maximum of 10 listeners can be registered for any single event. This limit can be changed for individual EventEmitter instances using the emitter.setMaxListeners(n) method. To change the default for allEventEmitter instances, the events.defaultMaxListenersproperty can be used. If this value is not a positive number, a RangeErroris thrown.

Take caution when setting the events.defaultMaxListeners because the change affects allEventEmitter instances, including those created before the change is made. However, calling emitter.setMaxListeners(n) still has precedence over events.defaultMaxListeners.

This is not a hard limit. The EventEmitter instance will allow more listeners to be added but will output a trace warning to stderr indicating that a "possible EventEmitter memory leak" has been detected. For any singleEventEmitter, the emitter.getMaxListeners() and emitter.setMaxListeners()methods can be used to temporarily avoid this warning:

import { EventEmitter } from "node:events";
const emitter = new EventEmitter();
emitter.setMaxListeners(emitter.getMaxListeners() + 1);
emitter.once("event", () => {
  // do stuff
  emitter.setMaxListeners(Math.max(emitter.getMaxListeners() - 1, 0));
});

The --trace-warnings command-line flag can be used to display the stack trace for such warnings.

The emitted warning can be inspected with process.on('warning') and will have the additional emitter, type, and count properties, referring to the event emitter instance, the event's name and the number of attached listeners, respectively. Its name property is set to 'MaxListenersExceededWarning'.

v0.11.2

node_modules/@types/node/events.d.ts:446

errorMonitor

static readonly errorMonitor: typeof errorMonitor;

This symbol shall be used to install a listener for only monitoring 'error'events. Listeners installed using this symbol are called before the regular'error' listeners are called.

Installing a listener using this symbol does not change the behavior once an'error' event is emitted. Therefore, the process will still crash if no regular 'error' listener is installed.

rawListeners()

rawListeners(eventName): Function[]

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

import { EventEmitter } from "node:events";
const emitter = new EventEmitter();
emitter.once("log", () => console.log("log once"));

// Returns a new Array with a function `onceWrapper` which has a property
// `listener` which contains the original listener bound above
const listeners = emitter.rawListeners("log");
const logFnWrapper = listeners[0];

// Logs "log once" to the console and does not unbind the `once` event
logFnWrapper.listener();

// Logs "log once" to the console and removes the listener
logFnWrapper();

emitter.on("log", () => console.log("log persistently"));
// Will return a new Array with a single function bound by `.on()` above
const newListeners = emitter.rawListeners("log");

// Logs "log persistently" twice
newListeners[0]();
emitter.emit("log");

Parameters

• eventName: string | symbol

Returns

Function[]

Since

v9.4.0

Source

node_modules/@types/node/events.d.ts:766

removeAllListeners()

removeAllListeners(event?): this

Removes all listeners, or those of the specified eventName.

It is bad practice to remove listeners added elsewhere in the code, particularly when the EventEmitter instance was created by some other component or module (e.g. sockets or file streams).

Returns a reference to the EventEmitter, so that calls can be chained.

Parameters

• event?: string | symbol

Returns

this

Since

v0.1.26

Source

node_modules/@types/node/events.d.ts:706

removeListener()

removeListener(eventName, listener): this

Removes the specified listener from the listener array for the event namedeventName.

const callback = (stream) => {
  console.log("someone connected!");
};
server.on("connection", callback);
// ...
server.removeListener("connection", callback);

removeListener() will remove, at most, one instance of a listener from the listener array. If any single listener has been added multiple times to the listener array for the specified eventName, then removeListener() must be called multiple times to remove each instance.

Once an event is emitted, all listeners attached to it at the time of emitting are called in order. This implies that anyremoveListener() or removeAllListeners() calls after emitting and before the last listener finishes execution will not remove them fromemit() in progress. Subsequent events behave as expected.

import { EventEmitter } from "node:events";
class MyEmitter extends EventEmitter {}
const myEmitter = new MyEmitter();

const callbackA = () => {
  console.log("A");
  myEmitter.removeListener("event", callbackB);
};

const callbackB = () => {
  console.log("B");
};

myEmitter.on("event", callbackA);

myEmitter.on("event", callbackB);

// callbackA removes listener callbackB but it will still be called.
// Internal listener array at time of emit [callbackA, callbackB]
myEmitter.emit("event");
// Prints:
//   A
//   B

// callbackB is now removed.
// Internal listener array [callbackA]
myEmitter.emit("event");
// Prints:
//   A

Because listeners are managed using an internal array, calling this will change the position indices of any listener registered after the listener being removed. This will not impact the order in which listeners are called, but it means that any copies of the listener array as returned by the emitter.listeners() method will need to be recreated.

When a single function has been added as a handler multiple times for a single event (as in the example below), removeListener() will remove the most recently added instance. In the example the once('ping')listener is removed:

import { EventEmitter } from "node:events";
const ee = new EventEmitter();

function pong() {
  console.log("pong");
}

ee.on("ping", pong);
ee.once("ping", pong);
ee.removeListener("ping", pong);

ee.emit("ping");
ee.emit("ping");

Returns a reference to the EventEmitter, so that calls can be chained.

Source

src/agent.ts:171

setMaxListeners()

setMaxListeners(n): this

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 toInfinity (or 0) to indicate an unlimited number of listeners.

Returns a reference to the EventEmitter, so that calls can be chained.

addAbortListener()

Experimental

static addAbortListener(signal, resource): Disposable

Listens once to the abort event on the provided signal.

Listening to the abort event on abort signals is unsafe and may lead to resource leaks since another third party with the signal can call e.stopImmediatePropagation(). Unfortunately Node.js cannot change this since it would violate the web standard. Additionally, the original API makes it easy to forget to remove listeners.

This API allows safely using AbortSignals in Node.js APIs by solving these two issues by listening to the event such that stopImmediatePropagation does not prevent the listener from running.

Returns a disposable so that it may be unsubscribed from more easily.

import { addAbortListener } from "node:events";

function example(signal) {
  let disposable;
  try {
    signal.addEventListener("abort", (e) => e.stopImmediatePropagation());
    disposable = addAbortListener(signal, (e) => {
      // Do something when signal is aborted.
    });
  } finally {
    disposable?.[Symbol.dispose]();
  }
}

Parameters

• signal: AbortSignal

• resource

Returns

Disposable

Disposable that removes the abort listener.

getEventListeners()

static getEventListeners(emitter, name): Function[]

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

For EventEmitters this behaves exactly the same as calling .listeners on the emitter.

For EventTargets this is the only way to get the event listeners for the event target. This is useful for debugging and diagnostic purposes.

import { getEventListeners, EventEmitter } from "node:events";

{
  const ee = new EventEmitter();
  const listener = () => console.log("Events are fun");
  ee.on("foo", listener);
  console.log(getEventListeners(ee, "foo")); // [ [Function: listener] ]
}
{
  const et = new EventTarget();
  const listener = () => console.log("Events are fun");
  et.addEventListener("foo", listener);
  console.log(getEventListeners(et, "foo")); // [ [Function: listener] ]
}

Parameters

• emitter: EventEmitter | _DOMEventTarget

• name: string | symbol

Returns

Function[]

node_modules/@types/node/events.d.ts:308

getMaxListeners()

static getMaxListeners(emitter): number

Returns the currently set max amount of listeners.

For EventEmitters this behaves exactly the same as calling .getMaxListeners on the emitter.

For EventTargets this is the only way to get the max event listeners for the event target. If the number of event handlers on a single EventTarget exceeds the max set, the EventTarget will print a warning.

import { getMaxListeners, setMaxListeners, EventEmitter } from "node:events";

{
  const ee = new EventEmitter();
  console.log(getMaxListeners(ee)); // 10
  setMaxListeners(11, ee);
  console.log(getMaxListeners(ee)); // 11
}
{
  const et = new EventTarget();
  console.log(getMaxListeners(et)); // 10
  setMaxListeners(11, et);
  console.log(getMaxListeners(et)); // 11
}

Parameters

const myEmitter = new EventEmitter();
myEmitter.on("event", () => {});
myEmitter.on("event", () => {});
console.log(listenerCount(myEmitter, "event"));

on()

static on(
   emitter,
   eventName,
options?): AsyncIterableIterator<any>

import { on, EventEmitter } from "node:events";
import process from "node:process";

const ee = new EventEmitter();

// Emit later on
process.nextTick(() => {
  ee.emit("foo", "bar");
  ee.emit("foo", 42);
});

for await (const event of on(ee, "foo")) {
  // The execution of this inner block is synchronous and it
  // processes one event at a time (even with await). Do not use
  // if concurrent execution is required.
  console.log(event); // prints ['bar'] [42]
}
// Unreachable here

Returns an AsyncIterator that iterates eventName events. It will throw if the EventEmitter emits 'error'. It removes all listeners when exiting the loop. The value returned by each iteration is an array composed of the emitted event arguments.

An AbortSignal can be used to cancel waiting on events:

import { on, EventEmitter } from "node:events";
import process from "node:process";

const ac = new AbortController();

(async () => {
  const ee = new EventEmitter();

  // Emit later on
  process.nextTick(() => {
    ee.emit("foo", "bar");
    ee.emit("foo", 42);
  });

  for await (const event of on(ee, "foo", { signal: ac.signal })) {
    // The execution of this inner block is synchronous and it
    // processes one event at a time (even with await). Do not use
    // if concurrent execution is required.
    console.log(event); // prints ['bar'] [42]
  }
  // Unreachable here
})();

process.nextTick(() => ac.abort());

Parameters

• emitter: EventEmitter

• eventName: string

The name of the event being listened for

• options?: StaticEventEmitterOptions

Returns

AsyncIterableIterator<any>

that iterates eventName events emitted by the emitter

once()

once(emitter, eventName, options)

static once(
   emitter,
   eventName,
options?): Promise<any[]>

Creates a Promise that is fulfilled when the EventEmitter emits the given event or that is rejected if the EventEmitter emits 'error' while waiting. The Promise will resolve with an array of all the arguments emitted to the given event.

This method is intentionally generic and works with the web platform EventTarget interface, which has no special'error' event semantics and does not listen to the 'error' event.

import { once, EventEmitter } from "node:events";
import process from "node:process";

const ee = new EventEmitter();

process.nextTick(() => {
  ee.emit("myevent", 42);
});

const [value] = await once(ee, "myevent");
console.log(value);

const err = new Error("kaboom");
process.nextTick(() => {
  ee.emit("error", err);
});

try {
  await once(ee, "myevent");
} catch (err) {
  console.error("error happened", err);
}

The special handling of the 'error' event is only used when events.once()is used to wait for another event. If events.once() is used to wait for the 'error' event itself, then it is treated as any other kind of event without special handling:

import { EventEmitter, once } from "node:events";

const ee = new EventEmitter();

once(ee, "error")
  .then(([err]) => console.log("ok", err.message))
  .catch((err) => console.error("error", err.message));

ee.emit("error", new Error("boom"));

// Prints: ok boom

An AbortSignal can be used to cancel waiting for the event:

import { EventEmitter, once } from "node:events";

const ee = new EventEmitter();
const ac = new AbortController();

async function foo(emitter, event, signal) {
  try {
    await once(emitter, event, { signal });
    console.log("event emitted!");
  } catch (error) {
    if (error.name === "AbortError") {
      console.error("Waiting for the event was canceled!");
    } else {
      console.error("There was an error", error.message);
    }
  }
}

foo(ee, "foo", ac.signal);
ac.abort(); // Abort waiting for the event
ee.emit("foo"); // Prints: Waiting for the event was canceled!
