    Type Alias TypedEventTarget<T>

    Strongly-typed subset of the DOM EventTarget API using CustomEvent<detail>.

    This abstraction ensures that event listeners always receive a typed CustomEvent with a strongly-typed detail payload.

    type TypedEventTarget<T extends Record<string, unknown>> = {
        addEventListener<K extends string | number | symbol>(
            type: K,
            listener: (event: CustomEvent<T[K]>) => void,
            options?: boolean | AddEventListenerOptions,
        ): void;
        dispatch<K extends string | number | symbol>(
            type: K,
            detail: T[K],
        ): boolean;
        dispatchEvent(e: Event): boolean;
        removeEventListener<K extends string | number | symbol>(
            type: K,
            listener: (event: CustomEvent<T[K]>) => void,
            options?: boolean | EventListenerOptions,
        ): void;
    }

    Type Parameters

    • T extends Record<string, unknown>
