What is nanoevents?

Nanoevents is a tiny (less than 1KB) event emitter library for JavaScript. It provides a simple and efficient way to handle events in your application, making it ideal for both client-side and server-side development.

What are nanoevents's main functionalities?

Event Emission

This feature allows you to emit events with associated data. The `emit` method triggers all listeners attached to the specified event.

const { createNanoEvents } = require('nanoevents');
const emitter = createNanoEvents();
emitter.emit('event', 'data');

Event Listening

This feature allows you to listen for specific events. The `on` method registers a callback function that will be called whenever the specified event is emitted.

const { createNanoEvents } = require('nanoevents');
const emitter = createNanoEvents();
emitter.on('event', data => {
  console.log(data);
});
emitter.emit('event', 'data');

Event Unsubscription

This feature allows you to unsubscribe from events. The `on` method returns an unsubscribe function that can be called to remove the listener.

const { createNanoEvents } = require('nanoevents');
const emitter = createNanoEvents();
const unsubscribe = emitter.on('event', data => {
  console.log(data);
});
emitter.emit('event', 'data');
unsubscribe();
emitter.emit('event', 'data');
