ExtendEventProvider TypeAlias

Allows an interface to extend interfaces that already extend an IEventProvider.

Signature

export type ExtendEventProvider<TBaseEvent extends IEvent, TBase extends IEventProvider<TBaseEvent>, TEvent extends TBaseEvent> = Omit<Omit<Omit<TBase, "on">, "once">, "off"> & IEventProvider<TBaseEvent> & IEventProvider<TEvent>;

Type Parameters

Parameter	Constraint	Description
TBaseEvent	IEvent
TBase	IEventProvider<TBaseEvent>
TEvent	TBaseEvent

Example

interface AEvents extends IEvent{
 (event: "a-event",listener: (a: number)=>void);
}
interface A extends IEventProvider<AEvents>{
 a: object;
}
interface BEvents extends IEvent{
 (event: "b-event",listener: (b: string)=>void);
}
interface B extends ExtendEventProvider<AEvents, A, BEvents>{
 b: boolean;
};

interface B will now extend interface A and its events
