Angular Debugging

Using ng-inspect chrome extension

ng-inspect is a light weight Chrome extension for debugging AngularJS applications.

When a node is selected from the elements panel, the scope related info is displayed in the ng-inspect panel.

Exposes few global variables for quick access of scope/isolateScope.

$s -- scope of the selected node
$is -- isolateScope of the selected node
$el -- jQuery element reference of the selected node (requiers jQuery)
$events -- events present on the selected node (requires jQuery)

Provides easy access to Services/Factories.

Use $get() to retrieve the instance of a service/factory by name.

Performance of the application can be monitored by counting the no.of scopes,isolateScopes, watchers and listeners on the application.

Use $count() to get the count of scopes, isolateScopes, watchers and listeners.

Note: This extension will work only when the debugInfo is enabled.
