10 lines of js to log all $emit events in AngularJS

$rootScope.$emit is a great way of propagating events around your app. This snippet will log them without touching to the rest of you app.

As your AngularJS app grows, you'll feel the need to split it into dozens of services, directives and controllers. $rootScope.$emit is a great way of sharing information with other modules: it does not make your modules require each other and it does not clutter scopes with global variables.

However, there are times when you'd like to know exactly which events you are sending. This will do it for you. I keep it commented somewhere close :).

myApp.config(['$provide', function ($provide) {
  $provide.decorator('$rootScope', function ($delegate) {
    var _emit = $delegate.$emit;

    $delegate.$emit = function () {
      console.log.apply(console, arguments);
      _emit.apply(this, arguments);
    };

    return $delegate;
  });
}]);
