What is @walletconnect/events?

@walletconnect/events is a lightweight event emitter library designed to facilitate event-driven programming. It allows developers to create, listen to, and manage custom events within their applications.

What are @walletconnect/events's main functionalities?

Event Emission

This feature allows you to emit custom events. The code sample demonstrates how to create an event emitter instance and emit an event named 'eventName' with 'eventData'.

const { EventEmitter } = require('@walletconnect/events');
const emitter = new EventEmitter();
emitter.emit('eventName', 'eventData');

Event Listening

This feature allows you to listen for custom events. The code sample shows how to set up an event listener for 'eventName' and handle the event data when it is emitted.

const { EventEmitter } = require('@walletconnect/events');
const emitter = new EventEmitter();
emitter.on('eventName', (data) => {
  console.log('Event received:', data);
});
emitter.emit('eventName', 'eventData');

Event Removal

This feature allows you to remove event listeners. The code sample demonstrates how to add an event listener, remove it, and then emit the event to show that the listener has been removed.

const { EventEmitter } = require('@walletconnect/events');
const emitter = new EventEmitter();
const handler = (data) => {
  console.log('Event received:', data);
};
emitter.on('eventName', handler);
emitter.off('eventName', handler);
emitter.emit('eventName', 'eventData');
