    off: <TData = unknown>(type: string, listener?: (event: TData) => void) => void

    Remove event listener If no listener is specified, all listeners will be removed

    Type Declaration

      • <TData = unknown>(type: string, listener?: (event: TData) => void): void

      • Type Parameters

        • TData = unknown

        Parameters

        • type: string

          Event type

        • Optionallistener: (event: TData) => void

          Event listener

        Returns void

    listener must be a function

    on: <TData = unknown, TType extends string = string>(
        type: TType,
        listener: EventListener<TData, TType>,
        thisArg?: ThisType<unknown>,
    ) => void

    Add new event listener

    Type Declaration

      • <TData = unknown, TType extends string = string>(
            type: TType,
            listener: EventListener<TData, TType>,
            thisArg?: ThisType<unknown>,
        ): void

      • Type Parameters

        • TData = unknown
        • TType extends string = string

        Parameters

        • type: TType

          Event type. If the event type is xAPI, the listener's event parameter will be of type XAPIEvent. Any dispatched XAPIEvent will trigger the xAPI event.

        • listener: EventListener<TData, TType>

          Event listener

        • OptionalthisArg: ThisType<unknown>

          Optionally specify the listener's this value

        Returns void

    listener must be a function

    once: <TData = unknown, TType extends string = string>(
        type: TType,
        listener: EventListener<TData, TType>,
        thisArg?: ThisType<unknown>,
    ) => void

    Add new event listener that will be fired only once

    Type Declaration

      • <TData = unknown, TType extends string = string>(
            type: TType,
            listener: EventListener<TData, TType>,
            thisArg?: ThisType<unknown>,
        ): void

      • Type Parameters

        • TData = unknown

        Parameters

        • type: TType

          Event type. If the event type is xAPI, the listener's event parameter will be of type XAPIEvent. Any dispatched XAPIEvent will trigger the xAPI event.

        • listener: EventListener<TData, TType>

          Event listener

        • OptionalthisArg: ThisType<unknown>

          Optionally specify the listener's this value

        Returns void
