Suggestions from Jeff Browning at Pinecone on improving my skills at AngularJS and Rails.

AngularJS

• Build custom directives. Basic controllers and templates are great, but anything beyond basic interactivity usually requires custom directives. The learning curve for custom directives can be challenging, so just take it one step at a time.
• Inter-directive communication via controllers.
• Become very familiar with scope usage, best practices, and pitfalls. Scope inheritance, and encapsulation are some of the areas where Angular can drive you insane, but this knowledge is essential in order to build large-scale, maintainable Angular apps.
• Explore the differences between Services, Factories, and Providers.
• Become a testing expert. One thing that I like about the Angular community is that tests are expected and encouraged.

Ruby/Rails

• Build a good foundation to your knowledge by becoming familiar with software design patterns and antipatterns. This knowledge really helps when we're building large apps. Some great resources to learn more are:

• Become familiar with web API design
• Become very familiar with other web app best practices such as REST

AngularJS and scope.$apply

TODO: Write a directive that can be used for password confirmation.

Here's my implementation:

.directive('match', function () {
  return {
    restrict: 'A',
    require: ['^form', 'ngModel'],
    link: function (scope, element, attrs, ctrls) {
      var formCtrl = ctrls[0],
          inputCtrl = ctrls[1];

      var testForMatch = function (value, confirmation) {
        inputCtrl.$setValidity('match', value === confirmation);
      };

      scope.$watch(attrs.ngModel, function (confirmation) {
        testForMatch(scope.$eval(attrs.match), confirmation);
      });

      scope.$watch(attrs.match, function (value) {
        testForMatch(value, scope.$eval(attrs.ngModel));
      });
    }
  };
});
