Chrome DevTools Snippet for AngularJS apps.

chrome-angularjs.js

var ngAppElem = angular.element(document.querySelector('[ng-app]') || document);

window.$injector = ngAppElem.injector();
window.inject = $injector.invoke;
window.$rootScope = ngAppElem.scope();

// getService('auth') will create a variable `auth` assigned to the service `auth`.
var getService = serviceName =>
    inject([serviceName, s => window[serviceName] = s]);

Object.defineProperties(window, {
    $scope: {
        get() {
            var elem = angular.element($0);
            return elem.isolateScope() || elem.scope();
        },
    },
    $ctrl: {
        get() {
            return this.$scope.$ctrl;
        },
    },
});

/**
 * USAGE
 *
 * First copy the script and paste it in Chrome DevTools in Sources -> left pane -> Snippets.
 * Then, after loading an Angular page, right click on the snippet and choose "run".
 * Afterwards, you have the following available in the console:
 *
 * 1) $rootScope
 * 2) `inject(['$q', '$compile', function ($q, $compile) { /* ...use $q and $compile here... */ }])`
 * 3) Click on an element in DevTools; now `$scope` in the console points at the element scope
 *    (isolate if one exists) and `$ctrl` points to `$scope.$ctrl`.
 * 4) getService('foo') creates a global `foo` variable pointing to the `'foo'` service.
 *
 * Enjoy!

@vanowm could you be a bit more specific? I've just tested the snippet and it still works on latest stable AngularJS. I've updated one code snippet to use afterwards so that it works with AngularJS strict mode but other than that, I don't see issues.
