@vegajs/event-bus/dist/types/event-bus.d.ts

A flexible and typed Event Bus implementation for TypeScript and JavaScript projects. It facilitates communication between components and modules without tight coupling.

import type { EventBus as IEventBus } from './types';
export declare class EventBus<EventMap> implements IEventBus<EventMap> {
    private listeners;
    on<K extends keyof EventMap>(eventName: K, handler: (event: EventMap[K]) => void): void;
    off<K extends keyof EventMap>(eventName: K, handler: (event: EventMap[K]) => void): void;
    emit<K extends keyof EventMap>(eventName: K, event: EventMap[K]): void;
    offAll(): void;
}
