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 @peetertomberg/registry. Try it out:
const registry = require("@peetertomberg/registry");
const instance = registry.createRegistry();
const callback = (...args) => console.log(...args);
// Triggered when a key is registered
instance.eventBus.on(instance.events.REGISTER, callback);
// Triggered when a key is unregistered
instance.eventBus.on(instance.events.UNREGISTER, callback);
console.log('Will log out key and value to console from event register');
instance.register('key', 'value');
console.log('Will log out key from event unregister');
instance.unregister('key');
