async-node-events - npm Package Versions

2.0.0 - 2019-11-08

Changed

• BREAKING: EventEmitter is exported from module.
  • For CommonJS use const {EventEmitter} = require('async-node-events');
  • For ES Modules use import {EventEmitter} from 'async-node-events';
• BREAKING: Make emit() async function and resolve to true/false if listeners were called rather than returning this.
• BREAKING: Listeners called through sync functions (on, off, etc) will all be called in a sync manner, and must not return a Promise.
• BREAKING: emitSync is now like emit but only handles synchronous listeners.
• BREAKING: emit and emitSync return false when cancelled and true if not cancelled. This differs from Node.js API that indicates if there were listeners. Use listenerCount to check for listeners.
• Update dependencies.
• Switch from gulp to simple npm scripts and nyc.
• Switch to ES modules using 'esm' for Node.js support.
• Update test suite.
• Modernize code.
  • async/await
  • arrow functions
  • various new ES features
  • use Map
