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

Throws

listener must be a function

on

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

Throws

listener must be a function

once

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
      • 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.

        Event listener

      • OptionalthisArg: ThisType<unknown>

        Optionally specify the listener's this value

      Returns void

Throws
