Event emitter for generators

Installation

npm i event-generator --production

Or

npm i event-generator && npm test

Usage

This tiny library provides easy for await ... of approach to events and iteration through them asynchronously. Let's take a look:

    const EventGenerator = require('event-generator');
    const emitter = new EventGenerator();
    
    setTimeout(() => emitter.emit('event', 'Hello!', true), 5);
    for await (const event of emitter.listen('event')) {
      console.log(event);
    }
    emitter.destroy();

It allows to make your code more synchronous-like, even if most of it based on events.

Attention!

Yes, because of return nature, you can pass only one argument ti .emit and second is stop_flag, if you pass it true, then asynchronous loop wil stop.

Methods

• .listen(<event>) - returns async generator iterable for emitted events
• .emit(<event>, <data>, [<stop_flag>]) - emits <data> to <event> to listeners, can stop the iteration/listening
• .destroy() - removes all listeners
