RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including ee-proxy. Try it out:
const EventEmitter = require('events');
const emitterProxy = require('../lib/ee-proxy');
const user = new EventEmitter();
user.once('disconnect', () => console.log('User disconnected'));
class Game extends EventEmitter {
constructor(user) {
super();
this._user = emitterProxy(user);
this._user.once('game:cancel', () => this._onUserLeft());
this._user.once('disconnect', () => this._onUserLeft());
}
start() {
this._user.on('game:message', message => console.log('game:message', message));
this._user.on('game:command', command => console.log('game:command', command));
}
_onUserLeft() {
console.log('User left the game');
this._user.stopListening(); // removes only game listeners ("game:message" and "game:command" events)
this.emit('canceled');
}
}
const game = new Game(user);
game.start();
console.log(user.eventNames());
game.once('canceled', () => {
console.log(user.eventNames());
});
user.emit('game:cancel');
