    The asyncemit allows you to emit an event to an EventEmitter3 asynchronously.

    Installation

    The module is released in the public npm registry and can be installed using:

    npm install --save asyncemit
    

    Usage

    To make this pattern work there are a couple of preconditions that need to be satisfied:

    1. The method should be added on either a class that inherits from the EventEmitter or on a new EventEmitter instance.
    2. The number of arguments expected by a listener function should match the number of arguments passed to the asyncemit method excluding the event name.

    See the following example:

    var EventEmitter = require('eventemitter3')
      , asyncemit = require('asyncemit');
     
    var ee = new EventEmitter();
    ee.asyncemit = asyncemit;
     
    //
    // The next `foo` listeners will not be executed until `next` is called.
    //
    ee.on('foo', function (arg, next) {
      // Do things with arg?
      next();
    });
     
    //
    // Still executed, but synchronously.
    //
    ee.on('foo', function (arg) {
     
    });
     
    ee.asyncemit('foo', 'bar', function (err) {
      //
      // The error argument will be set if one of the async listeners called the
      // `next` callback with an `error` argument.
      //
    });
