Trying to achieve es6-dispatcher API https://github.com/rambler-digital-solutions/es6-dispatcher

dispatcher.js

var Dispatcher = require('dispatcher');

module.exports = class View extends Backbone.View {

  constructor(...args) {
    this.dispatcher = dispatcher.bind(this); // Why?
    super(...args);
  }

  save() {
    return co.call(this, function * () {
      yield this.dispatcher('before save');
      super.save();
      yield this.dispatcher('after save');
    });
  }
  
};

dispatcher2.js

var Dispatcher = require('dispatcher');

module.exports = class View extends Backbone.View {

  constructor(...args) {
    this.hooks = {}; // for debug?
    this.dispatcher = new Dispatcher(this.hooks); // optional hooks?
  }

  save(...args) {
    return co.call(this, function * () {
      yield this.dispatcher.before('save');
      var result = super.save();
      yield this.dispatcher.after('save');
      retur result;
    });
  }
  
};

dispatcher3.js

// Questions:
// - Strong order?
// - Globs
// - Support async?
var Dispatcher = require('dispatcher');

module.exports = class View extends Backbone.View {

  constructor(...args) {
    this.dispatcher = new Dispatcher();
    this.dispatcher.hooks; // useful to debug?
  }

  save(...args) {
    return co.call(this, function * () {
      yield this.dispatcher.get('save:before');
      var result = super.save();
      yield this.dispatcher.get('save:after');
      // yield this.dispatcher.get('save:*');
      retur result;
    });
  }
  
};
