micro-event-bus-service v0.0.22

micro-event-bus

A minimal event bus for cross-component communication in JavaScript apps, making it easier to manage events across different parts of your application without tightly coupling components.

Installation

To install micro-event-bus, run the following command in your project directory:

npm install micro-event-bus

Usage

Importing the Library

First, import micro-event-bus into your project:

const MicroEventBus = require('micro-event-bus');

Creating an Event Bus Instance

Create an instance of the event bus:

const eventBus = new MicroEventBus();

Emitting Events

To emit an event, use the emitEvent method:

eventBus.emitEvent('my-event', { data: 'Example data' });

Registering Event Listeners

Register an event listener with the registerEvent method:

const listenerId = eventBus.registerEvent('my-event', (data) => {
console.log(`Received event data: \${data}`);
});

Optionally, you can debounce or throttle the listener by providing options:

const debouncedListenerId = eventBus.registerEvent('my-event', (data) => {
console.log(`Debounced event data: \${data}`);
}, { debounce: 200 });

const throttledListenerId = eventBus.registerEvent('my-event', (data) => {
console.log(`Throttled event data: \${data}`);
}, { throttle: 100 });

Unregistering Event Listeners

To unregister an event listener, you'll need to implement a mechanism to track and remove listeners based on their IDs:

eventBus.unregisterEvent(listenerId);
