      Parameters

      • eventName: string | symbol
      • listener: (...args: any[]) => void

        Returns this

      inheritedoffset

      • offset(offset: number, options?: boolean | Readonly<{ skipBinding?: boolean }>): QueryBuilder<TRecord, TResult>
      • Parameters

        • offset: number

        Returns QueryBuilder<TRecord, TResult>

      inheritedon

      • on(eventName: string | symbol, listener: (...args: any[]) => void): this
      • 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.

        server.on('connection', (stream) => {
        console.log('someone connected!');
        });

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

        By default, event listeners are invoked in the order they are added. The emitter.prependListener() method can be used as an alternative to add the event listener to the beginning of the listeners array.

        import { EventEmitter } from 'node:events';
        const myEE = new EventEmitter();
        myEE.on('foo', () => console.log('a'));
        myEE.prependListener('foo', () => console.log('b'));
        myEE.emit('foo');
        // Prints:
        // b
        // a
        @since

        v0.1.101


        Parameters

        • eventName: string | symbol

          The name of the event.

        • listener: (...args: any[]) => void

          The callback function

          Returns this

        inheritedonce

        • once(eventName: string | symbol, listener: (...args: any[]) => void): this
        • Adds a one-time listener function for the event named eventName. The next time eventName is triggered, this listener is removed and then invoked.

          server.once('connection', (stream) => {
          console.log('Ah, we have our first user!');
          });

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

          By default, event listeners are invoked in the order they are added. The emitter.prependOnceListener() method can be used as an alternative to add the event listener to the beginning of the listeners array.

          import { EventEmitter } from 'node:events';
          const myEE = new EventEmitter();
          myEE.once('foo', () => console.log('a'));
          myEE.prependOnceListener('foo', () => console.log('b'));
          myEE.emit('foo');
          // Prints:
          // b

Multiple calls passing the same combination of eventName and listener will result in the listener being added, and called, multiple times.

            server.prependListener('connection', (stream) => {
            console.log('someone connected!');
            });

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

            inheritedprependOnceListener

            • prependOnceListener(eventName: string | symbol, listener: (...args: any[]) => void): this
            • 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.

              server.prependOnceListener('connection', (stream) => {
              console.log('Ah, we have our first user!');
              });

              inheritedrawListeners

              • rawListeners(eventName: string | symbol): 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[]

              inheritedremoveAllListeners

              • removeAllListeners(eventName?: string | symbol): 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

                • optionaleventName: string | symbol

                Returns this

              inheritedremoveListener

              • removeListener(eventName: string | symbol, listener: (...args: any[]) => void): this
              • Removes the specified listener from the listener array for the event named eventName.

                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 any removeListener() 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.

                inheritedsetMaxListeners

                • setMaxListeners(n: number): 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 to Infinity (or 0) to indicate an unlimited number of listeners.

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