Batarang FAQ

How do I measure a directive's performance?

If your directive uses $watch, you should be able to see the watch expression wherever your directive is used.

My $watch functions show up as just "function ()" in the performance tab

Use named functions for $watch:

scope.$watch(function checkIfSomethingChanged() { 
  // ...
}, function whenThatChanges(newValue, oldValue) {
  // ...
});
