It has been micro-optimized +for various of code paths making this, one of, if not the fastest EventEmitter +available for Node.js and browsers. The module is API compatible with the +EventEmitter that ships by default with Node.js but there are some slight +differences: + +- Domain support has been removed. +- We do not `throw` an error when you emit an `error` event and nobody is + listening. +- The `newListener` and `removeListener` events have been removed as they + are useful only in some uncommon use-cases. +- The `setMaxListeners`, `getMaxListeners`, `prependListener` and + `prependOnceListener` methods are not available. +- Support for custom context for events so there is no need to use `fn.bind`. +- The `removeListener` method removes all matching listeners, not only the + first. + +It's a drop in replacement for existing EventEmitters, but just faster. Free +performance, who wouldn't want that? The EventEmitter is written in EcmaScript 3 +so it will work in the oldest browsers and node versions that you need to +support. + +## Installation + +```bash +$ npm install --save eventemitter3 +``` + +## CDN + +Recommended CDN: + +```text +https://unpkg.com/eventemitter3@latest/dist/eventemitter3.umd.min.js +``` + +## Usage + +After installation the only thing you need to do is require the module: + +```js +var EventEmitter = require('eventemitter3'); +``` + +And you're ready to create your own EventEmitter instances. For the API +documentation, please follow the official Node.js documentation: + +http://nodejs.org/api/events.html + +### Contextual emits + +We've upgraded the API of the `EventEmitter.on`, `EventEmitter.once` and +`EventEmitter.removeListener` to accept an extra argument which is the `context` +or `this` value that should be set for the emitted events. This means you no +longer have the overhead of an event that required `fn.bind` in order to get a +custom `this` value. + +```js +var EE = new EventEmitter() + , context = { foo: 'bar' }; + +function emitted() { + console.log(this === context); // true +} + +EE.once('event-name', emitted, context); +EE.on('another-event', emitted, context); +EE.removeListener('another-event', emitted, context); +``` + +### Tests and benchmarks + +To run tests run `npm test`. To run the benchmarks run `npm run benchmark`. + +Tests and benchmarks are not included in the npm package. If you want to play +with them you have to clone the GitHub repository. Note that you will have to +run an additional `npm i` in the benchmarks folder before `npm run benchmark`. + +## License + +[MIT](LICENSE) Index: node_modules/eventemitter3/dist/eventemitter3.esm.js =================================================================== --- node_modules/eventemitter3/dist/eventemitter3.esm.js (revision a762898ecd37a452c782821d4c2c4955c6ed2521) +++ node_modules/eventemitter3/dist/eventemitter3.esm.js (revision a762898ecd37a452c782821d4c2c4955c6ed2521) @@ -0,0 +1,355 @@ +function getDefaultExportFromCjs (x) { + return x && x.__esModule && Object.prototype.hasOwnProperty.call(x, 'default') ? x['default'] : x; +} + +var eventemitter3 = {exports: {}}; + +var hasRequiredEventemitter3; + +function requireEventemitter3 () { + if (hasRequiredEventemitter3) return eventemitter3.exports; + hasRequiredEventemitter3 = 1; + (function (module) { + + var has = Object.prototype.hasOwnProperty + , prefix = '~'; + + /** + * Constructor to create a storage for our `EE` objects. + * An `Events` instance is a plain object whose properties are event names. + * + * @constructor + * @private + */ + function Events() {} + + // + // We try to not inherit from `Object.prototype`.
