Introduction to Emitterify

Emitterify is a lightweight JavaScript library designed for event management. It enhances your application’s interactivity by enabling custom event handling, which is particularly useful for building complex client-side applications. In this blog post, we’ll explore dozens of useful APIs provided by Emitterify, complete with code snippets, and demonstrate how you can integrate it into your app.

Basic Usage

Let’s start with the basics. First, you need to install Emitterify:

  
    npm install emitterify
  

Creating an Emitter

To create an emitter:

  
    const emitter = Emitterify();
  

Listening to Events

Add an event listener:

  
    emitter.on('data', data => {
      console.log(data);
    });
  

Emitting Events

Emit an event:

  
    emitter.emit('data', { key: 'value' });
  

Once Listeners

Add a listener that will only trigger once:

  
    emitter.once('data', data => {
      console.log('One-time listener:', data);
    });
  

Remove Event Listener

Remove an event listener:

  
    const off = emitter.on('data', data => {
      console.log('This will be removed');
    });
    off();
