MultiMediator

MultiMediator is a lightweight npm package that provides an EventEmitter interface, allowing you to manage events across different channels. This package enables you to create isolated event channels, making it easier to organize and handle events in your application.

Installation

You can install MultiMediator via npm:

npm install multimediator

Usage

To use MultiMediator, you need to initialize it with a channel name. Each channel operates independently, allowing you to emit and listen for events without interference from other channels.

Basic Example

const MultiMediator = require('multimediator');
// Initialize a new MultiMediator instance with a channel name
const channelA = new MultiMediator('channelA');

// Listen for an event on channelA
channelA.on('event', (data) => {
    console.log('Received on channelA:', data);
});

// Emit an event on channelA
channelA.emit('event', { message: 'Hello from channelA!' });

Multiple Channels

You can create multiple instances of MultiMediator for different channels:

JavaScript
Копировать
const channelB = new MultiMediator('channelB');

channelB.on('event', (data) => {
    console.log('Received on channelB:', data);
});

// Emit an event on channelB
channelB.emit('event', { message: 'Hello from channelB!' });

Key Features

• Independent Channels: Each channel is isolated, preventing event conflicts.
• Event Handling: Use the standard EventEmitter methods (on, emit, off) to manage events.
• Lightweight: Minimal footprint, making it suitable for performance-sensitive applications.
