It uses API Gateway with Lambda to host the backend, while the frontend is deployed with Amplify.\r\n\r\nThis project contains two elements: on the backend are some Lambda functions in the `/lambda` directory, and in `/frontend` an Angular 9 app.\r\n"

Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.\n\n## Code scaffolding\n\nRun `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.\n\n## Build\n\nRun `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `--prod` flag for a production build.\n\n## Running unit tests\n\nRun `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).\n\n## Running end-to-end tests\n\nRun `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).\n\n## Further help\n\nTo get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/master/README.md).\n"

It uses\\n            Spotify's <a href=\\\"https://developer.spotify.com/web-api/\\\">Web API</a> to display your listening history, define\\n            your top genres, and to recommend under-the-radar songs you might like.\\n          </p>\\n          <p>\\n            The global popularity ratings of the artists in your lists are aggregated to result in an Obscurity score\\n            which is compared to the Obscurify users in your country to show how unique (or energetic, danceable, and happy) a music taste you have.\\n          </p>\\n          <p>\\n            Obscurify can also make playlists of the music in your track lists and place them in your Spotify library - including the historical snapshots\\n            that are saved when you view your Obscurify profile each month.\\n          </p>\\n\\n          <p>\\n            Background Photo on login page by Photo by MARK S. on Unsplash. \\n          </p>\\n    </section>\\n    \\n    <section>\\n        <h2>F.A.Q.</h2>\\n    \\n        <h3>How is my data used?</h3>\\n        <p>\\n          To use Obscurify, you'll need to allow the app to have access to some of your account information -\\n          that being your username, the country your account is registered to, and the artists/tracks\\n          that appear on your lists.\\n        </p>\\n      \\n        <h3>Where does the artist and track ranking come from?</h3>\\n        <p>\\n        The content and order of your lists come directly from <a href=\\\"https://developer.spotify.com/web-api/\\\">Spotify's API</a>.\\n        Popularity, genres, and musical traits are all determined by Spotify.\\n        </p>\\n      \\n        <h3>Why are there no (or few) results showing up in my All-Time and Current lists?</h3>\\n        <p>\\n        If you listen in Private Mode, those songs will not be recorded and won't be reflected in either list.\\n        If your account is fairly new, it is normal for your All-Time list to be short, as it takes some time for Spotify to update their information.\\n        </p>\\n      \\n        <h3>Some of the genres seem a little off...</h3>\\n        <p>\\n        Spotify can attribute some artists with a few dozen genres. These range from very general (like \\\"rock\\\") to a little\\n        more interesting (like \\\"escape room\\\").\\n        </p>\\n      \\n        <h3>My lists aren't updating</h3>\\n        <p>\\n        There is no defined schedule for when Spotify updates the data in your lists - it's normal for delays, but expect an average of one to two weeks.\\n        </p>\\n      \\n        <h3>I have some other issue (or concern, compliment, maybe a suggestion)</h3>\\n        <p>\\n          I'd like to know about it! <a href=\\\"mailto:oliveroalex@gmail.com\\\">Send me an email!</a>\\n        </p>  \\n    </section>\\n     \\n</main>\\n\");\n\n/***/ }),\n\n/***/ \"./node_modules/raw-loader/dist/cjs.js!./src/app/components/artist/artist-card/artist-card.component.html\":\n/*!****************************************************************************************************************!*\\\n  !*** ./node_modules/raw-loader/dist/cjs.js!./src/app/components/artist/artist-card/artist-card.component.html ***!\n  \\****************************************************************************************************************/\n/*! exports provided: default */\n/***/ (function(module, __webpack_exports__, __webpack_require__) {\n\n\"use strict\";\n__webpack_require__.r(__webpack_exports__);\n/* harmony default export */ __webpack_exports__[\"default\"] = (\"<div class=\\\"artist__card\\\" [ngClass]=\\\"{'active': activeView}\\\">\\n    <img [src]=\\\"artist.images[1].url\\\" />\\n    <div class=\\\"artist__card__info\\\">\\n        <div fxLayout=\\\"row\\\" fxLayoutAlign=\\\"flex-start start\\\">\\n            <span fxFlex=\\\"0 0 auto\\\"> {{ i + 1 }} /</span> \\n\\n            <div fxLayout=\\\"column\\\" fxFlex=\\\"1 1 auto\\\" fxLayoutAlign=\\\"center start\\\">\\n                <p class=\\\"artist__card__info--primary\\\">\\n                    {{(artist.name.length < 20) ?

entries to be evaluated when the expression\n * bound to the trigger changes.\n *\n * \\@usageNotes\n * Define an animation trigger in the `animations` section of `\\@Component` metadata.\n * In the template, reference the trigger by name and bind it to a trigger expression that\n * evaluates to a defined animation state, using the following format:\n *\n * `[\\@triggerName]=\"expression\"`\n *\n * Animation trigger bindings convert all values to strings, and then match the\n * previous and current values against any linked transitions.\n * Booleans can be specified as `1` or `true` and `0` or `false`.\n *\n * ### Usage Example\n *\n * The following example creates an animation trigger reference based on the provided\n * name value.\n * The provided animation value is expected to be an array consisting of state and\n * transition declarations.\n *\n * ```typescript\n * \\@Component({\n *   selector: \"my-component\",\n *   templateUrl: \"my-component-tpl.html\",\n *   animations: [\n *     trigger(\"myAnimationTrigger\", [\n *       state(...),\n *       state(...),\n *       transition(...),\n *       transition(...)\n *     ])\n *   ]\n * })\n * class MyComponent {\n *   myStatusExp = \"something\";\n * }\n * ```\n *\n * The template associated with this component makes use of the defined trigger\n * by binding to an element within its template code.\n *\n * ```html\n * <!-- somewhere inside of my-component-tpl.html -->\n * <div [\\@myAnimationTrigger]=\"myStatusExp\">...</div>\n * ```\n *\n * ### Using an inline function\n * The `transition` animation method also supports reading an inline function which can decide\n * if its associated animation should be run.\n *\n * ```typescript\n * // this method is run each time the `myAnimationTrigger` trigger value changes.\n * function myInlineMatcherFn(fromState: string, toState: string, element: any, params: {[key:\n * string]: any}): boolean {\n *   // notice that `element` and `params` are also available here\n *   return toState == 'yes-please-animate';\n * }\n *  /\n *   selector: 'my-component',\n *   templateUrl: 'my-component-tpl.html',\n *   animations: [\n *     trigger('myAnimationTrigger', [\n *       transition(myInlineMatcherFn, [\n *         // the animation sequence code\n *       ]),\n *     ])\n *   ]\n * })\n * class MyComponent {\n *   myStatusExp = \"yes-please-animate\";\n * }\n * ```\n *\n * ### Disabling Animations\n * When true, the special animation control binding `\\@.disabled` binding prevents\n * all animations from rendering.\n * Place the  `\\@.disabled` binding on an element to disable\n * animations on the element itself, as well as any inner animation triggers\n * within the element.\n *\n * The following example shows how to use this feature:\n *\n * ```typescript /\n *   selector: 'my-component',\n *   template: `\n *     <div [\\@.disabled]=\"isDisabled\">\n *       <div [\\@childAnimation]=\"exp\"></div>\n *     </div>\n *   `,\n *   animations: [\n *     trigger(\"childAnimation\", [\n *       // ...\n *     ])\n *   ]\n * })\n * class MyComponent {\n *   isDisabled = true;\n *   exp = '...';\n * }\n * ```\n *\n * When `\\@.disabled` is true, it prevents the `\\@childAnimation` trigger from animating,\n * along with any inner animations.\n *\n * ### Disable animations application-wide\n * When an area of the template is set to have animations disabled,\n * **all** inner components have their animations disabled as well.\n * This means that you can disable all animations for an app\n * by placing a host binding set on `\\@.disabled` on the topmost Angular component.\n *\n * ```typescript\n * import {Component, HostBinding} from '\\@angular/core';\n *  /\n *   selector: 'app-component',\n *   templateUrl: 'app.component.html',\n * })\n * class AppComponent {\n * \\@HostBinding('@.disabled')\n *   public animationsDisabled = true;\n * }\n * ```\n *\n * ### Overriding disablement of inner animations\n * Despite inner animations being disabled, a parent animation can `query()`\n * for inner elements located in disabled areas of the template and still animate\n * them if needed. This is also the case for when a sub animation is\n * queried by a parent and then later animated using `animateChild()`.\n *\n * ### Detecting when an animation is disabled\n * If a region of the DOM (or the entire application) has its animations disabled, the animation\n * trigger callbacks still fire, but for zero seconds. When the callback fires, it provides\n * an instance of an `AnimationEvent`. If animations are disabled,\n * the `.disabled` flag on the event is true.\n *\n * \\@publicApi\n * @param {?} name An identifying string.\n * @param {?} definitions  An animation definition object, containing an array of `state()`\n * and `transition()` declarations.\n *\n * @return {?} An object that encapsulates the trigger data.\n *\n */\nfunction trigger(name, definitions) {\n    return { type: 7 /* Trigger */, name, definitions, options: {} };\n}\n/**\n * Defines an animation step that combines styling information with timing information.\n *\n * \\@usageNotes\n * Call within an animation `sequence()`, `{\\@link animations/group group()}`, or\n * `transition()` call to specify an animation step\n * that applies given style data to the parent animation for a given amount of time.\n *\n * ### Syntax Examples\n * **Timing examples**\n *\n * The following examples show various `timings` specifications.\n * - `animate(500)` : Duration is 500 milliseconds.\n * - `animate(\"1s\")` : Duration is 1000 milliseconds.\n * - `animate(\"100ms 0.5s\")` : Duration is 100 milliseconds, delay is 500 milliseconds.\n * - `animate(\"5s ease-in\")` : Duration is 5000 milliseconds, easing in.\n * - `animate(\"5s 10ms cubic-bezier(.17,.67,.88,.1)\")` : Duration is 5000 milliseconds, delay is 10\n * milliseconds, easing according to a bezier curve.\n *\n * **Style examples**\n *\n * The following example calls `style()` to set a single CSS style.\n * ```typescript\n * animate(500, style({ background: \"red\" }))\n * ```\n * The following example calls `keyframes()` to set a CSS style\n * to different values for successive keyframes.\n * ```typescript\n * animate(500, keyframes(\n *  [\n *   style({ background: \"blue\" })),\n *   style({ background: \"red\" }))\n *  ])\n * ```\n *\n * \\@publicApi\n * @param {?} timings Sets `AnimateTimings` for the parent animation.\n * A string in the format \"duration [delay] [easing]\".\n *  - Duration and delay are expressed as a number and optional time unit,\n * such as \"1s\" or \"10ms\" for one second and 10 milliseconds, respectively.\n * The default unit is milliseconds.\n *  - The easing value controls how the animation accelerates and decelerates\n * during its runtime.

Angular automatically adds or removes\n * CSS styles to ensure that the element is in the correct final state.\n *\n * The following example defines a transition that starts by hiding the element,\n * then makes sure that it animates properly to whatever state is currently active for trigger:\n *\n * ```typescript\n * transition(\"void => *\", [\n *   style({ opacity: 0 }),\n *   animate(500)\n *  ])\n * ```\n * ### Boolean value matching\n * If a trigger binding value is a Boolean, it can be matched using a transition expression\n * that compares true and false or 1 and 0. For example:\n *\n * ```\n * // in the template\n * <div [\\@openClose]=\"open ? true : false\">...</div>\n * // in the component metadata\n * trigger('openClose', [\n *   state('true', style({ height: '*' })),\n *   state('false', style({ height: '0px' })),\n *   transition('false <=> true', animate(500))\n * ])\n * ```\n *\n * \\@publicApi\n *\n * @param {?} stateChangeExpr A Boolean expression or function that compares the previous and current\n * animation states, and returns true if this transition should occur.

Since the start/end timing\n * values are collected for each property then if the current animation step is animating the same\n * property and its timing values fall anywhere into the window of time that the property is\n * currently being animated within then this is what causes an error.\n *\n * 2. Timing values\n * The validator will validate to see if a timing value of `duration delay easing` or\n * `durationNumber` is valid or not.\n *\n * (note that upon validation the code below will replace the timing data with an object containing\n * {duration,delay,easing}.\n *\n * 3. Offset Validation\n * Each of the style() calls are allowed to have an offset value when placed inside of keyframes().\n * Offsets within keyframes() are considered valid when:\n *\n *   - No offsets are used at all\n *   - Each style() entry contains an offset value\n *   - Each offset is between 0 and 1\n *   - Each offset is greater to or equal than the previous one\n *\n * Otherwise an error will be thrown.\n */\n/**\n * @param {?} driver\n * @param {?} metadata\n * @param {?} errors\n * @return {?}\n */\nfunction buildAnimationAst(driver, metadata, errors) {\n    return new

DSL code.\n *\n * The code below will be converted from:\n *\n * ```\n * sequence([\n *   style({ opacity: 0 }),\n *   animate(1000, style({ opacity: 0 }))\n * ])\n * ```\n *\n * To:\n * ```\n * keyframes = [{ opacity: 0, offset: 0 }, { opacity: 1, offset: 1 }]\n * duration = 1000\n * delay = 0\n * easing = ''\n * ```\n *\n * For this operation to cover the combination of animation verbs (style, animate, group, etc...) a\n * combination of prototypical inheritance, AST traversal and merge-sort-like algorithms are used.\n *\n * [AST Traversal]\n * Each of the animation verbs, when executed, will return an string-map object representing what\n * type of action it is (style, animate, group, etc...) and the data associated with it. This means\n * that when functional composition mix of these functions is evaluated (like in the example above)\n * then it will end up producing a tree of objects representing the animation itself.\n *\n * When this animation object tree is processed by the visitor code below it will visit each of the\n * verb statements within the visitor. And during each visit it will build the context of the\n * animation keyframes by interacting with the `TimelineBuilder`.\n *\n * [TimelineBuilder]\n * This class is responsible for tracking the styles and building a series of keyframe objects for a\n * timeline between a start and end time. The builder starts off with an initial timeline and each\n * time the AST comes across a `group()`, `keyframes()` or a combination of the two wihtin a\n * `sequence()` then it will generate a sub timeline for each step as well as a new one after\n * they are complete.\n *\n * As the AST is traversed, the timing state on each of the timelines will be incremented. If a sub\n * timeline was created (based on one of the cases above) then the parent timeline will attempt to\n * merge the styles used within the sub timelines into itself (only with group() this will happen).\n * This happens with a merge operation (much like how the merge works in mergesort) and it will only\n * copy the most recently used styles from the sub timelines into the parent timeline. This ensures\n * that if the styles are used later on in another phase of the animation then they will be the most\n * up-to-date values.\n *\n * [How Missing Styles Are Updated]\n * Each timeline has a `backFill` property which is responsible for filling in new styles into\n * already processed keyframes if a new style shows up later within the animation sequence.\n *\n * ```\n * sequence([\n *   style({ width: 0 }),\n *   animate(1000, style({ width: 100 })),\n *   animate(1000, style({ width: 200 })),\n *   animate(1000, style({ width: 300 }))\n *   animate(1000, style({ width: 400, height: 400 })) // notice how `height` doesn't exist anywhere\n * else\n * ])\n * ```\n *\n * What is happening here is that the `height` value is added later in the sequence, but is missing\n * from all previous animation steps. Therefore when a keyframe is created it would also be missing\n * from all previous keyframes up until where it is first used. For the timeline keyframe generation\n * to properly fill in the style it will place the previous value (the value from the parent\n * timeline) or a default value of `*` into the backFill object. Given that each of the keyframe\n * styles are objects that prototypically inhert from the backFill object, this means that if a\n * value is added into the backFill then it will automatically propagate any missing values to all\n * keyframes. Therefore the missing `height` value will be properly filled into the already\n * processed keyframes.\n *\n * When a sub-timeline is created it will have its own backFill property. This is done so that\n * styles present within the sub-timeline do not accidentally seep into the previous/future timeline\n * keyframes\n *\n * (For prototypically-inherited contents to be detected a `for(i in obj)` loop must be used.)\n *\n * [Validation]\n * The code in this file is not responsible for validation.

Instead, ngClass and ngStyle should have their input values be converted\n * into something that the core-level [style] and [class] bindings understand.\n *\n * This [StylingDiffer] class handles this conversion by creating a new input value each time\n * the inner representation of the binding value have changed.\n *\n * ## Why do we care about ngStyle/ngClass?\n * The styling algorithm code (documented inside of `render3/interfaces/styling.ts`) needs to\n * respect and understand the styling values emitted through ngStyle and ngClass (when they\n * are present and used in a template).\n *\n * Instead of having these directives manage styling on their own, they should be included\n * into the Angular styling algorithm that exists for [style] and [class] bindings.\n *\n * Here's why:\n *\n * - If ngStyle/ngClass is used in combination with [style]/[class] bindings then the\n *   styles and classes would fall out of sync and be applied and updated at\n *   inconsistent times\n * - Both ngClass/ngStyle do not respect [class.name] and [style.prop] bindings\n *   (they will write over them given the right combination of events)\n *\n *   ```\n *   <!-- if `w1` is updated then it will always override `w2`\n *        if `w2` is updated then it will always override `w1`\n *        if both are updated at the same time then `w1` wins -->\n *   <div [ngStyle]=\"{width:w1}\" [style.width]=\"w2\">...</div>\n *\n *   <!-- if `w1` is updated then it will always lose to `w2`\n *        if `w2` is updated then it will always override `w1`\n *        if both are updated at the same time then `w2` wins -->\n *   <div [style]=\"{width:w1}\" [style.width]=\"w2\">...</div>\n *   ```\n * - ngClass/ngStyle were written as a directives and made use of maps, closures and other\n *   expensive data structures which were evaluated each time CD runs\n * @template T\n */\nclass StylingDiffer {\n    /**\n     * @param {?} _name\n     * @param {?} _options\n     */\n    constructor(_name, _options) {\n        this._name = _name;\n        this._options = _options;\n        this.value = null;\n        this._lastSetValue = null;\n        this._lastSetValueType = 0 /* Null */;\n        this._lastSetValueIdentityChange = false;\n    }\n    /**\n     * Sets (updates) the styling value within the differ.\n     *\n     * Only when `hasValueChanged` is called then this new value will be evaluted\n     * and checked against the previous value.\n     *\n     * @param {?} value the new styling value provided from the ngClass/ngStyle binding\n     * @return {?}\n     */\n    setValue(value) {\n        if (Array.isArray(value)) {\n            this._lastSetValueType = 4 /* Array */;\n        }\n        else if (value instanceof Set) {\n            this._lastSetValueType = 8 /* Set */;\n        }\n        else if (value && typeof value === 'string') {\n            if (!(this._options & 4 /* AllowStringValue */)) {\n                throw new Error(this._name + ' string values are not allowed');\n            }\n            this._lastSetValueType = 1 /* String */;\n        }\n        else {\n            this._lastSetValueType = value ? 2 /* Map */ : 0 /* Null */;\n        }\n        this._lastSetValueIdentityChange = true;\n        this._lastSetValue = value || null;\n    }\n    /**\n     * Determines whether or not the value has changed.\n     *\n     * This function can be called right after `setValue()` is called, but it can also be\n     * called incase the existing value (if it's a collection) changes internally.

Useful when the expression is\n * more complex then a property access, for example when using the async pipe (`userStreams |\n * async`).\n * - `index: number`: The index of the current item in the iterable.\n * - `first: boolean`: True when the item is the first item in the iterable.\n * - `last: boolean`: True when the item is the last item in the iterable.\n * - `even: boolean`: True when the item has an even index in the iterable.\n * - `odd: boolean`: True when the item has an odd index in the iterable.\n *\n * ### Change propagation\n *\n * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:\n *\n * * When an item is added, a new instance of the template is added to the DOM.\n * * When an item is removed, its template instance is removed from the DOM.\n * * When items are reordered, their respective templates are reordered in the DOM.\n *\n * Angular uses object identity to track insertions and deletions within the iterator and reproduce\n * those changes in the DOM. This has important implications for animations and any stateful\n * controls that are present, such as `<input>` elements that accept user input. Inserted rows can\n * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state\n * such as user input.\n * For more on animations, see [Transitions and Triggers](guide/transition-and-triggers).\n *\n * The identities of elements in the iterator can change while the data does not.\n * This can happen, for example, if the iterator is produced from an RPC to the server, and that\n * RPC is re-run. Even if the data hasn't changed, the second response produces objects with\n * different identities, and Angular must tear down the entire DOM and rebuild it (as if all old\n * elements were deleted and all new elements inserted).\n *\n * To avoid this expensive operation, you can customize the default tracking algorithm.\n * by supplying the `trackBy` option to `NgForOf`.\n * `trackBy` takes a function that has two arguments: `index` and `item`.\n * If `trackBy` is given, Angular tracks changes by the return value of the function.\n *\n * @see [Structural Directives](guide/structural-directives)\n * \\@ngModule CommonModule\n * \\@publicApi\n * @template T\n */\nclass NgForOf {\n    /**\n     * @param {?} _viewContainer\n     * @param {?} _template\n     * @param {?} _differs\n     */\n    constructor(_viewContainer, _template, _differs) {\n        this._viewContainer = _viewContainer;\n        this._template = _template;\n        this._differs = _differs;\n        this._ngForOfDirty = true;\n        this._differ = null;\n    }\n    /**\n     * The value of the iterable expression, which can be used as a\n     * [template input variable](guide/structural-directives#template-input-variable).\n     * @param {?} ngForOf\n     * @return {?}\n     */\n    set ngForOf(ngForOf) {\n        this._ngForOf = ngForOf;\n        this._ngForOfDirty = true;\n    }\n    /**\n     * A function that defines how to track changes for items in the iterable.\n     *\n     * When items are added, moved, or removed in the iterable,\n     * the directive must re-render the appropriate DOM nodes.\n     * To minimize churn in the DOM, only nodes that have changed\n     * are re-rendered.\n     *\n     * By default, the change detector assumes that\n     * the object instance identifies the node in the iterable.\n     * When this function is supplied, the directive uses\n     * the result of calling this function to identify the item node,\n     * rather than the identity of the object itself.\n     *\n     * The function receives two inputs,\n     * the iteration index and the node object ID.\n     * @param {?} fn\n     * @return {?}\n     */\n    set ngForTrackBy(fn) {\n        if (Object(_angular_core__WEBPACK_IMPORTED_MODULE_0__[\"isDevMode\"])() && fn != null && typeof fn !== 'function') {\n            // TODO(vicb): use a log service once there is a public one available\n            if ((/** @type {?} */ (console)) && (/** @type {?} */ (console.warn))) {\n                console.warn(`trackBy must be a function, but received ${JSON.stringify(fn)}. ` +\n                    `See https://angular.io/docs/ts/latest/api/common/index/NgFor-directive.html#!#change-propagation for more information.`);\n            }\n        }\n        this._trackByFn = fn;\n    }\n    /**\n     * @return {?}\n     */\n    get ngForTrackBy() { return this._trackByFn; }\n    /**\n     * A reference to the template that is stamped out for each item in the iterable.\n     * @see [template reference variable](guide/template-syntax#template-reference-variables--var-)\n     * @param {?} value\n     * @return {?}\n     */\n    set ngForTemplate(value) {\n        // TODO(TS2.1): make TemplateRef<Partial<NgForRowOf<T>>> once we move to TS v2.1\n        // The current type is too restrictive; a template that just uses index, for example,\n        // should be acceptable.\n        if (value) {\n            this._template = value;\n        }\n    }\n    /**\n     * Applies the changes when needed.\n     * @return {?}\n     */\n    ngDoCheck() {\n        if (this._ngForOfDirty) {\n            this._ngForOfDirty = false;\n            // React on ngForOf changes only once all inputs have been initialized\n            /** @type {?} */\n            const value = this._ngForOf;\n            if (!this._differ && value) {\n                try {\n                    this._differ = this._differs.find(value).create(this.ngForTrackBy);\n                }\n                catch (_a) {\n                    throw new Error(`Cannot find a differ supporting object '${value}' of type '${getTypeName(value)}'.

For example, consider the following shorthand statement,\n * that is meant to show a loading page while waiting for data to be loaded.\n *\n * ```\n * <div class=\"hero-list\" *ngIf=\"heroes else loading\">\n *  ...\n * </div>\n *\n * <ng-template #loading>\n *  <div>Loading...</div>\n * </ng-template>\n * ```\n *\n * You can see that the \"else\" clause references the `<ng-template>`\n * with the `#loading` label, and the template for the \"then\" clause\n * is provided as the content of the anchor element.\n *\n * However, when Angular expands the shorthand syntax, it creates\n * another `<ng-template>` tag, with `ngIf` and `ngIfElse` directives.\n * The anchor element containing the template for the \"then\" clause becomes\n * the content of this unlabeled `<ng-template>` tag.\n *\n * ```\n * <ng-template [ngIf]=\"hero-list\" [ngIfElse]=\"loading\">\n *  <div class=\"hero-list\">\n *   ...\n *  </div>\n * </ng-template>\n *\n * <ng-template #loading>\n *  <div>Loading...</div>\n * </ng-template>\n * ```\n *\n * The presence of the implicit template object has implications for the nesting of\n * structural directives. For more on this subject, see\n * [Structural Directives](https://angular.io/guide/structural-directives#one-per-element).\n *\n * \\@ngModule CommonModule\n * \\@publicApi\n */\nclass NgIf {\n    /**\n     * @param {?} _viewContainer\n     * @param {?} templateRef\n     */\n    constructor(_viewContainer, templateRef) {\n        this._viewContainer = _viewContainer;\n        this._context = new NgIfContext();\n        this._thenTemplateRef = null;\n        this._elseTemplateRef = null;\n        this._thenViewRef = null;\n        this._elseViewRef = null;\n        this._thenTemplateRef = templateRef;\n    }\n    /**\n     * The Boolean expression to evaluate as the condition for showing a template.\n     * @param {?} condition\n     * @return {?}\n     */\n    set ngIf(condition) {\n        this._context.$implicit = this._context.ngIf = condition;\n        this._updateView();\n    }\n    /**\n     * A template to show if the condition expression evaluates to true.\n     * @param {?} templateRef\n     * @return {?}\n     */\n    set ngIfThen(templateRef) {\n        assertTemplate('ngIfThen', templateRef);\n        this._thenTemplateRef = templateRef;\n        this._thenViewRef = null;

\\@description\n *\n * Formats a date value according to locale rules.\n *\n * Only the `en-US` locale data comes with Angular. To localize dates\n * in another language, you must import the corresponding locale data.\n * See the [I18n guide](guide/i18n#i18n-pipes) for more information.\n *\n * @see `formatDate()`\n *\n *\n * \\@usageNotes\n *\n * The result of this pipe is not reevaluated when the input is mutated. To avoid the need to\n * reformat the date on every change-detection cycle, treat the date as an immutable object\n * and change the reference when the pipe needs to run again.\n *\n * ### Pre-defined format options\n *\n * Examples are given in `en-US` locale.\n *\n * - `'short'`: equivalent to `'M/d/yy, h:mm a'` (`6/15/15, 9:03 AM`).\n * - `'medium'`: equivalent to `'MMM d, y, h:mm:ss a'` (`Jun 15, 2015, 9:03:01 AM`).\n * - `'long'`: equivalent to `'MMMM d, y, h:mm:ss a z'` (`June 15, 2015 at 9:03:01 AM\n * GMT+1`).\n * - `'full'`: equivalent to `'EEEE, MMMM d, y, h:mm:ss a zzzz'` (`Monday,

equivalent to `'MMMM d, y'` (`June 15, 2015`).\n * - `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` (`Monday, June 15, 2015`).\n * - `'shortTime'`: equivalent to `'h:mm a'` (`9:03 AM`).\n * - `'mediumTime'`: equivalent to `'h:mm:ss a'` (`9:03:01 AM`).\n * - `'longTime'`: equivalent to `'h:mm:ss a z'` (`9:03:01 AM GMT+1`).\n * - `'fullTime'`: equivalent to `'h:mm:ss a zzzz'` (`9:03:01 AM

* Note that timezone correction is not applied to an ISO string that has no time component, such as \"2016-09-19\"\n *\n * ### Format examples\n *\n * These examples transform a date into various formats,\n * assuming that `dateObj` is a JavaScript `Date` object for\n * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,\n * given in the local time for the `en-US` locale.\n *\n * ```\n * {{ dateObj | date }}               // output is 'Jun 15, 2015'\n * {{ dateObj | date:'medium' }}      // output is 'Jun 15, 2015, 9:43:11 PM'\n * {{ dateObj | date:'shortTime' }}   // output is '9:43 PM'\n * {{ dateObj | date:'mm:ss' }}       // output is '43:11'\n * ```\n *\n * ### Usage example\n *\n * The following component uses a date pipe to display the current date in different formats.\n *\n * ```\n * \\@Component({\n *  selector: 'date-pipe',\n *  template: `<div>\n *    <p>Today is {{today | date}}</p>\n *    <p>Or if you prefer, {{today | date:'fullDate'}}</p>\n *    <p>The time is {{today | date:'h:mm a z'}}</p>\n *  </div>`\n * })\n * // Get the current date and time as a date-time value.\n * export class DatePipeComponent {\n *   today: number = Date.now();\n * }\n * ```\n *\n * \\@publicApi\n */\n// clang-format on\nclass DatePipe {\n    /**\n     * @param {?} locale\n     */\n    constructor(locale) {\n        this.locale = locale;\n    }\n    /**\n     *

The goal is to allow users to avoid the\n  most obvious pitfalls and do so without compromising performance significantly.\n  For ShadowDOM styling that's not covered here, a set of best practices\n  can be provided that should allow users to accomplish more complex styling.\n\n  The following is a list of specific ShadowDOM styling features and a brief\n  discussion of the approach used to shim.\n\n  Shimmed features:\n\n  * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host\n  element using the :host rule. To shim this feature, the :host styles are\n  reformatted and prefixed with a given scope name and promoted to a\n  document level stylesheet.\n  For example, given a scope name of .foo, a rule like this:\n\n    :host {\n        background: red;\n      }\n    }\n\n  becomes:\n\n    .foo {\n      background: red;\n    }\n\n  * encapsulation: Styles defined within ShadowDOM, apply only to\n  dom inside the ShadowDOM. Polymer uses one of two techniques to implement\n  this feature.\n\n  By default, rules are prefixed with the host element tag name\n  as a descendant selector. This ensures styling does not leak out of the 'top'\n  of the element's ShadowDOM. For example,\n\n  div {\n      font-weight: bold;\n    }\n\n  becomes:\n\n  x-foo div {\n      font-weight: bold;\n    }\n\n  becomes:\n\n\n  Alternatively, if WebComponents.ShadowCSS.strictStyling is set to true then\n  selectors are scoped by adding an attribute selector suffix to each\n  simple selector that contains the host element tag name. Each element\n  in the element's ShadowDOM template is also given the scope attribute.\n  Thus, these rules match only elements that have the scope attribute.\n  For example, given a scope name of x-foo, a rule like this:\n\n    div {\n      font-weight: bold;\n    }\n\n  becomes:\n\n    div[x-foo] {\n      font-weight: bold;\n    }\n\n  Note that elements that are dynamically added to a scope must have the scope\n  selector added to them manually.\n\n  * upper/lower bound encapsulation: Styles which are defined outside a\n  shadowRoot should not cross the ShadowDOM boundary and should not apply\n  inside a shadowRoot.\n\n  This styling behavior is not emulated. Some possible ways to do this that\n  were rejected due to complexity and/or performance concerns include: (1) reset\n  every possible property for every possible selector for a given scope name;\n  (2) re-implement css in javascript.\n\n  As an alternative, users should make sure to use selectors\n  specific to the scope in which they are working.\n\n  * ::distributed: This behavior is not emulated. It's often not necessary\n  to style the contents of a specific insertion point and instead, descendants\n  of the host element can be styled selectively. Users can also create an\n  extra node around an insertion point and style that node's contents\n  via descendent selectors. For example, with a shadowRoot like this:\n\n    <style>\n      ::content(div) {\n        background: red;\n      }\n    </style>\n    <content></content>\n\n  could become:\n\n    <style>\n      / *@polyfill .content-container div * /\n      ::content(div) {\n        background: red;\n      }\n    </style>\n    <div class=\"content-container\">\n      <content></content>\n    </div>\n\n  Note the use of @polyfill in the comment above a ShadowDOM specific style\n  declaration. This is a directive to the styling shim to use the selector\n  in comments in lieu of the next selector when running under polyfill.\n*/\nclass ShadowCss {\n    constructor() {\n        this.strictStyling = true;\n    }\n    /*\n    * Shim some cssText with the given selector.

Every element in the list\n * has identical properties.\n *\n * An `element` may inherit additional properties from `parentElement` If no `^parentElement` is\n * specified then `\"\"` (blank) element is assumed.\n *\n * NOTE: The blank element inherits from root `[Element]` element, the super element of all\n * elements.\n *\n * NOTE an element prefix such as `:svg:` has no special meaning to the schema.\n *\n * ## Properties\n *\n * Each element has a set of properties separated by `,` (commas). Each property can be prefixed\n * by a special character designating its type:\n *\n * - (no prefix): property is a string.\n * - `*`: property represents an event.\n * - `!`: property is a boolean.\n * - `#`: property is a number.\n * - `%`: property is an object.\n *\n * ## Query\n *\n * The class creates an internal squas representation which allows to easily answer the query of\n * if a given property exist on a given element.\n *\n * NOTE: We don't yet support querying for types or events.\n * NOTE: This schema is auto extracted from `schema_extractor.ts` located in the test folder,\n *       see dom_element_schema_registry_spec.ts\n */\n// =================================================================================================\n// =================================================================================================\n// =========== S T O P   -  S T O P   -  S T O P   -  S T O P   -  S T O P   -  S T O P  ===========\n// =================================================================================================\n// =================================================================================================\n//\n//                       DO NOT EDIT THIS DOM SCHEMA WITHOUT A SECURITY REVIEW!\n//\n// Newly added properties must be security reviewed and assigned an appropriate SecurityContext in\n// dom_security_schema.ts.

This sets up the\n * `InjectionToken` using this factory as a provider as if it was defined explicitly in the\n * application's root injector. If the factory function, which takes zero arguments, needs to inject\n * dependencies, it can do so using the `inject` function.

The mechanism used, to\n * activate support for map-based bindings at runtime is possible via the\n * `activeStylingMapFeature` function (which is also present in this file).\n *\n * # The Algorithm\n * Whenever a map-based binding updates (which is when the identity of the\n * map-value changes) then the map is iterated over and a `StylingMapArray` array\n * is produced. The `StylingMapArray` instance is stored in the binding location\n * where the `BINDING_INDEX` is situated when the `styleMap()` or `classMap()`\n * instruction were called. Once the binding changes, then the internal `bitMask`\n * value is marked as dirty.\n *\n * Styling values are applied once CD exits the element (which happens when\n * the `select(n)` instruction is called or the template function exits). When\n * this occurs, all prop-based bindings are applied. If a map-based binding is\n * present then a special flushing function (called a sync function) is made\n * available and it will be called each time a styling property is flushed.\n *\n * The flushing algorithm is designed to apply styling for a property (which is\n * a CSS property or a className value) one by one. If map-based bindings\n * are present, then the flushing algorithm will keep calling the maps styling\n * sync function each time a property is visited. This way, the flushing\n * behavior of map-based bindings will always be at the same property level\n * as the current prop-based property being iterated over (because everything\n * is alphabetically sorted).\n *\n * Let's imagine we have the following HTML template code:\n *\n * ```html\n * <div [style]=\"{width:'100px', height:'200px', 'z-index':'10'}\"\n *      [style.width.px]=\"200\">...</div>\n * ```\n *\n * When CD occurs, both the `[style]` and `[style.width]` bindings\n * are evaluated. Then when the styles are flushed on screen, the\n * following operations happen:\n *\n * 1. `[style.width]` is attempted to be written to the element.\n *\n * 2.  Once that happens, the algorithm instructs the map-based\n *     entries (`[style]` in this case) to \"catch up\" and apply\n *     all values up to the `width` value. When this happens the\n *     `height` value is applied to the element (since it is\n *     alphabetically situated before the `width` property).\n *\n * 3. Since there are no more prop-based entries anymore, the\n *    loop exits and then, just before the flushing ends, it\n *    instructs all map-based bindings to \"finish up\" applying\n *    their values.\n *\n * 4. The only remaining value within the map-based entries is\n *    the `z-index` value (`width` got skipped because it was\n *    successfully applied via the prop-based `[style.width]`\n *    binding). Since all map-based entries are told to \"finish up\",\n *    the `z-index` value is iterated over and it is then applied\n *    to the element.\n *\n * The most important thing to take note of here is that prop-based\n * bindings are evaluated in order alongside map-based bindings.\n * This allows all styling across an element to be applied in O(n)\n * time (a similar algorithm is that of the array merge algorithm\n * in merge sort).\n * @type {?}\n */\nconst syncStylingMap = (/**\n * @param {?} context\n * @param {?} renderer\n * @param {?} element\n * @param {?} data\n * @param {?} applyStylingFn\n * @param {?} sanitizer\n * @param {?} mode\n * @param {?=} targetProp\n * @param {?=} defaultValue\n * @return {?}\n */\n(context, renderer, element, data, applyStylingFn, sanitizer, mode, targetProp, defaultValue) => {\n    /** @type {?} */\n    let targetPropValueWasApplied = false;\n    // once the map-based styling code is activate it is never deactivated.

Unlike ngDoCheck, ngOnChanges and ngOnInit, which are\n// called during a pre-order traversal of the view tree (that is calling the\n// parent hooks before the child hooks) these events are sent in using a\n// post-order traversal of the tree (children before parents). This changes the\n// meaning of initIndex in the view state. For ngOnInit, initIndex tracks the\n// expected nodeIndex which a ngOnInit should be called. When sending\n// ngAfterContentInit and ngAfterViewInit it is the expected count of\n// ngAfterContentInit or ngAfterViewInit methods that have been called. This\n// ensure that despite being called recursively or after picking up after an\n// exception, the ngAfterContentInit or ngAfterViewInit will be called on the\n// correct nodes. Consider for example, the following (where E is an element\n// and D is a directive)\n//  Tree:       pre-order index  post-order index\n//    E1        0                6\n//      E2      1                1\n//       D3     2                0\n//      E4      3                5\n//       E5     4                4\n//        E6    5                2\n//        E7    6                3\n// As can be seen, the post-order index has an unclear relationship to the\n// pre-order index (postOrderIndex === preOrderIndex - parentCount +\n// childCount). Since number of calls to ngAfterContentInit and ngAfterViewInit\n// are stable (will be the same for the same view regardless of exceptions or\n// recursion) we just need to count them which will roughly correspond to the\n// post-order index (it skips elements and directives that do not have\n// lifecycle hooks).\n//\n// For example, if an exception is raised in the E6.onAfterViewInit() the\n// initIndex is left at 3 (by shouldCallLifecycleInitHook() which set it to\n// initIndex + 1). When checkAndUpdateView() is called again D3, E2 and E6 will\n// not have their ngAfterViewInit() called but, starting with E7, the rest of\n// the view will begin getting ngAfterViewInit() called until a check and\n// pass is complete.\n//\n// This algorthim also handles recursion.

caveats\n *\n * Note two important points about `isStable`, demonstrated in the examples below:\n * - the application will never be stable if you start any kind\n * of recurrent asynchronous task when the application starts\n * (for example for a polling process, started with a `setInterval`, a `setTimeout`\n * or using RxJS operators like `interval`);\n * - the `isStable` Observable runs outside of the Angular zone.\n *\n * Let's imagine that you start a recurrent task\n * (here incrementing a counter, using RxJS `interval`),\n * and at the same time subscribe to `isStable`.\n *\n * ```\n * constructor(appRef: ApplicationRef) {\n *   appRef.isStable.pipe(\n *      filter(stable => stable)\n *   ).subscribe(() => console.log('App is stable now');\n *   interval(1000).subscribe(counter => console.log(counter));\n * }\n * ```\n * In this example, `isStable` will never emit `true`,\n * and the trace \"App is stable now\" will never get logged.\n *\n * If you want to execute something when the app is stable,\n * you have to wait for the application to be stable\n * before starting your polling process.\n *\n * ```\n * constructor(appRef: ApplicationRef) {\n *   appRef.isStable.pipe(\n *     first(stable => stable),\n *     tap(stable => console.log('App is stable now')),\n *     switchMap(() => interval(1000))\n *   ).subscribe(counter => console.log(counter));\n * }\n * ```\n * In this example, the trace \"App is stable now\" will be logged\n * and then the counter starts incrementing every second.\n *\n * Note also that this Observable runs outside of the Angular zone,\n * which means that the code in the subscription\n * to this Observable will not trigger the change detection.\n *\n * Let's imagine that instead of logging the counter value,\n * you update a field of your component\n * and display it in its template.\n *\n * ```\n * constructor(appRef: ApplicationRef) {\n *   appRef.isStable.pipe(\n *     first(stable => stable),\n *     switchMap(() => interval(1000))\n *   ).subscribe(counter => this.value = counter);\n * }\n * ```\n * As the `isStable` Observable runs outside the zone,\n * the `value` field will be updated properly,\n * but the template will not be refreshed!\n *\n * You'll have to manually trigger the change detection to update the template.\n *\n * ```\n * constructor(appRef: ApplicationRef, cd: ChangeDetectorRef) {\n *   appRef.isStable.pipe(\n *     first(stable => stable),\n *     switchMap(() => interval(1000))\n *   ).subscribe(counter => {\n *     this.value = counter;\n *     cd.detectChanges();\n *   });\n * }\n * ```\n *\n * Or make the subscription callback run inside the zone.\n *\n * ```\n * constructor(appRef: ApplicationRef, zone: NgZone) {\n *   appRef.isStable.pipe(\n *     first(stable => stable),\n *     switchMap(() => interval(1000))\n *   ).subscribe(counter => zone.run(() => this.value = counter));\n * }\n * ```\n *\n *

It's possible for the identities of items\n * to change while the data does not. This can happen, for example, if the items are produced\n * from an RPC to the server, and that RPC is re-run. Even if the data hasn't changed, the\n * second response will produce objects with different identities.\n *\n * To customize the default option comparison algorithm, `<select>` supports `compareWith` input.\n * `compareWith` takes a **function** which has two arguments: `option1` and `option2`.\n * If `compareWith` is given, Angular selects option by the return value of the function.\n *\n * ```ts\n * const selectedCountriesControl = new FormControl();\n * ```\n *\n * ```\n * <select [compareWith]=\"compareFn\"  [formControl]=\"selectedCountriesControl\">\n *     <option *ngFor=\"let country of countries\" [ngValue]=\"country\">\n *         {{country.name}}\n *     </option>\n * </select>\n *\n * compareFn(c1: Country, c2: Country): boolean {\n *     return c1 && c2 ? c1.id === c2.id : c1 === c2;\n * }\n * ```\n *\n * **Note:** We listen to the 'change' event because 'input' events aren't fired\n * for selects in Firefox and IE:\n * https://bugzilla.mozilla.org/show_bug.cgi?id=1024350\n * https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/4660045/\n *\n * \\@ngModule ReactiveFormsModule\n * \\@ngModule FormsModule\n * \\@publicApi\n */\nclass SelectControlValueAccessor {\n    /**\n     * @param {?} _renderer\n     * @param {?} _elementRef\n     */\n    constructor(_renderer, _elementRef) {\n        this._renderer = _renderer;\n        this._elementRef = _elementRef;\n        /**\n         * \\@internal\n         */\n        this._optionMap = new Map();\n        /**\n         * \\@internal\n         */\n        this._idCounter = 0;\n        /**\n         * \\@description\n         * The registered callback function called when a change event occurs on the input element.\n         */\n        this.onChange = (/**\n         * @param {?} _\n         * @return {?}\n         */\n        (_) => { });\n        /**\n         * \\@description\n         * The registered callback function called when a blur event occurs on the input element.\n         */\n        this.onTouched = (/**\n         * @return {?}\n         */\n        () => { });\n        this._compareWith = _angular_core__WEBPACK_IMPORTED_MODULE_0__[\"ɵlooseIdentical\"];\n    }\n    /**\n     * \\@description\n     * Tracks the option comparison algorithm for tracking identities when\n     * checking for changes.\n     * @param {?} fn\n     * @return {?}\n     */\n    set compareWith(fn) {\n        if (typeof fn !== 'function') {\n            throw new Error(`compareWith must be a function, but received ${JSON.stringify(fn)}`);\n        }\n        this._compareWith = fn;\n    }\n    /**\n     * Sets the \"value\" property on the input element.

You access its properties by exporting it into a\n * local template variable using `ngForm` such as (`#f=\"ngForm\"`). Use the variable where\n * needed on form submission.\n *\n * If you do need to populate initial values into your form, using a one-way binding for\n * `ngModel` tends to be sufficient as long as you use the exported form's value rather\n * than the domain model's value on submit.\n *\n * ### Using ngModel within a form\n *\n * The following example shows controls using `ngModel` within a form:\n *\n * {\\@example forms/ts/simpleForm/simple_form_example.ts region='Component'}\n *\n * ### Using a standalone ngModel within a group\n *\n * The following example shows you how to use a standalone ngModel control\n * within a form.

First, developers have found this pattern\n * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's\n * an input/output property named `ngModel` on the reactive form directive that simply\n * approximates (some of) its behavior. Specifically, it allows getting/setting the value\n * and intercepting value events. However, some of `ngModel`'s other features - like\n * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,\n * which has understandably caused some confusion.\n *\n * In addition, this pattern mixes template-driven and reactive forms strategies, which\n * we generally don't recommend because it doesn't take advantage of the full benefits of\n * either strategy. Setting the value in the template violates the template-agnostic\n * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in\n * the class removes the convenience of defining forms in the template.\n *\n * To update your code before v7, you'll want to decide whether to stick with reactive form\n * directives (and get/set values using reactive forms patterns) or switch over to\n * template-driven directives.\n *\n * After (choice 1 - use reactive forms):\n *\n * ```html\n * <input [formControl]=\"control\">\n * ```\n *\n * ```ts\n * this.control.setValue('some value');\n * ```\n *\n * After (choice 2 - use template-driven forms):\n *\n * ```html\n * <input [(ngModel)]=\"value\">\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * By default, when you use this pattern, you will see a deprecation warning once in dev\n * mode. You can choose to silence this warning by providing a config for\n * `ReactiveFormsModule` at import time:\n *\n * ```ts\n * imports: [\n *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'});\n * ]\n * ```\n *\n * Alternatively, you can choose to surface a separate warning for each instance of this\n * pattern with a config value of `\"always\"`. This may help to track down where in the code\n * the pattern is being used as the code is being updated.\n *\n * \\@ngModule ReactiveFormsModule\n * \\@publicApi\n */\nclass FormControlDirective extends NgControl {\n    /**\n     * @param {?} validators\n     * @param {?} asyncValidators\n     * @param {?} valueAccessors\n     * @param {?} _ngModelWarningConfig\n     */\n    constructor(validators, asyncValidators, valueAccessors, _ngModelWarningConfig) {\n        super();\n        this._ngModelWarningConfig = _ngModelWarningConfig;\n        /**\n         * @deprecated as of v6\n         */\n        this.update = new _angular_core__WEBPACK_IMPORTED_MODULE_0__[\"EventEmitter\"]();\n        /**\n         * \\@description\n         * Instance property used to track whether an ngModel warning has been sent out for this\n         * particular `FormControlDirective` instance.

First, developers have found this pattern\n * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's\n * an input/output property named `ngModel` on the reactive form directive that simply\n * approximates (some of) its behavior. Specifically, it allows getting/setting the value\n * and intercepting value events. However, some of `ngModel`'s other features - like\n * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,\n * which has understandably caused some confusion.\n *\n * In addition, this pattern mixes template-driven and reactive forms strategies, which\n * we generally don't recommend because it doesn't take advantage of the full benefits of\n * either strategy. Setting the value in the template violates the template-agnostic\n * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in\n * the class removes the convenience of defining forms in the template.\n *\n * To update your code before v7, you'll want to decide whether to stick with reactive form\n * directives (and get/set values using reactive forms patterns) or switch over to\n * template-driven directives.\n *\n * After (choice 1 - use reactive forms):\n *\n * ```html\n * <form [formGroup]=\"form\">\n *   <input formControlName=\"first\">\n * </form>\n * ```\n *\n * ```ts\n * this.form.get('first').setValue('some value');\n * ```\n *\n * After (choice 2 - use template-driven forms):\n *\n * ```html\n * <input [(ngModel)]=\"value\">\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * By default, when you use this pattern, you will see a deprecation warning once in dev\n * mode. You can choose to silence this warning by providing a config for\n * `ReactiveFormsModule` at import time:\n *\n * ```ts\n * imports: [\n *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'})\n * ]\n * ```\n *\n * Alternatively, you can choose to surface a separate warning for each instance of this\n * pattern with a config value of `\"always\"`. This may help to track down where in the code\n * the pattern is being used as the code is being updated.\n *\n * \\@ngModule ReactiveFormsModule\n * \\@publicApi\n */\nclass FormControlName extends NgControl {\n    /**\n     * @param {?} parent\n     * @param {?} validators\n     * @param {?} asyncValidators\n     * @param {?} valueAccessors\n     * @param {?} _ngModelWarningConfig\n     */\n    constructor(parent, validators, asyncValidators, valueAccessors, _ngModelWarningConfig) {\n        super();\n        this._ngModelWarningConfig = _ngModelWarningConfig;\n        this._added = false;\n        /**\n         * @deprecated as of v6\n         */\n        this.update = new _angular_core__WEBPACK_IMPORTED_MODULE_0__[\"EventEmitter\"]();\n        /**\n         * \\@description\n         * Instance property used to track whether an ngModel warning has been sent out for this\n         * particular FormControlName instance.

The 'Chat' component is placed into the 'aux' outlet.\n *\n * ```\n * [{\n *   path: 'team/:id',\n *   component: Team\n * }, {\n *   path: 'chat/:user',\n *   component: Chat\n *   outlet: 'aux'\n * }]\n * ```\n *\n * ### Wild Cards\n *\n * The following route uses wild-card notation to specify a component\n * that is always instantiated regardless of where you navigate to.\n *\n * ```\n * [{\n *   path: '**',\n *   component: WildcardComponent\n * }]\n * ```\n *\n * ### Redirects\n *\n * The following route uses the `redirectTo` property to ignore a segment of\n * a given URL when looking for a child path.\n *\n * When navigating to '/team/11/legacy/user/jim', the router changes the URL segment\n * '/team/11/legacy/user/jim' to '/team/11/user/jim', and then instantiates\n * the Team component with the User child component in it.\n *\n * ```\n * [{\n *   path: 'team/:id',\n *   component: Team,\n *   children: [{\n *     path: 'legacy/user/:name',\n *     redirectTo: 'user/:name'\n *   }, {\n *     path: 'user/:name',\n *     component: User\n *   }]\n * }]\n * ```\n *\n * The redirect path can be relative, as shown in this example, or absolute.\n * If we change the `redirectTo` value in the example to the absolute URL segment '/user/:name',\n * the result URL is also absolute, '/user/jim'.\n * ### Empty Path\n *\n * Empty-path route configurations can be used to instantiate components that do not 'consume'\n * any URL segments.\n *\n * In the following configuration, when navigating to\n * `/team/11`, the router instantiates the 'AllUsers' component.\n *\n * ```\n * [{\n *   path: 'team/:id',\n *   component: Team,\n *   children: [{\n *     path: '',\n *     component: AllUsers\n *   }, {\n *     path: 'user/:name',\n *     component: User\n *   }]\n * }]\n * ```\n *\n * Empty-path routes can have children. In the following example, when navigating\n * to `/team/11/user/jim`, the router instantiates the wrapper component with\n * the user component in it.\n *\n * Note that an empty path route inherits its parent's parameters and data.\n *\n * ```\n * [{\n *   path: 'team/:id',\n *   component: Team,\n *   children: [{\n *     path: '',\n *     component: WrapperCmp,\n *     children: [{\n *       path: 'user/:name',\n *       component: User\n *     }]\n *   }]\n * }]\n * ```\n *\n * ### Matching Strategy\n *\n * The default path-match strategy is 'prefix', which means that the router\n * checks URL elements from the left to see if the URL matches a specified path.\n * For example, '/team/11/user' matches 'team/:id'.\n *\n * ```\n * [{\n *   path: '',\n *   pathMatch: 'prefix', //default\n *   redirectTo: 'main'\n * }, {\n *   path: 'main',\n *   component: Main\n * }]\n * ```\n *\n * You can specify the path-match strategy 'full' to make sure that the path\n * covers the whole unconsumed URL. It is important to do this when redirecting\n * empty-path routes. Otherwise, because an empty path is a prefix of any URL,\n * the router would apply the redirect even when navigating to the redirect destination,\n * creating an endless loop.\n *\n * In the following example, supplying the 'full' `pathMatch` strategy ensures\n * that the router applies the redirect if and only if navigating to '/'.\n *\n * ```\n * [{\n *   path: '',\n *   pathMatch: 'full',\n *   redirectTo: 'main'\n * }, {\n *   path: 'main',\n *   component: Main\n * }]\n * ```\n *\n * ### Componentless Routes\n *\n * You can share parameters between sibling components.\n * For example, suppose that two sibling components should go next to each other,\n * and both of them require an ID parameter. You can accomplish this using a route\n * that does not specify a component at the top level.\n *\n * In the following example, 'MainChild' and 'AuxChild' are siblings.\n * When navigating to 'parent/10/(a//aux:b)', the route instantiates\n * the main child and aux child components next to each other.\n * For this to work, the application component must have the primary and aux outlets defined.\n *\n * ```\n * [{\n *    path: 'parent/:id',\n *    children: [\n *      { path: 'a', component: MainChild },\n *      { path: 'b', component: AuxChild, outlet: 'aux' }\n *    ]\n * }]\n * ```\n *\n * The router merges the parameters, data, and resolve of the componentless\n * parent into the parameters, data, and resolve of the children.\n *\n * This is especially useful when child components are defined\n * with an empty path string, as in the following example.\n * With this configuration, navigating to '/parent/10' creates\n * the main child and aux components.\n *\n * ```\n * [{\n *    path: 'parent/:id',\n *    children: [\n *      { path: '', component: MainChild },\n *      { path: '', component: AuxChild, outlet: 'aux' }\n *    ]\n * }]\n * ```\n *\n * ### Lazy Loading\n *\n * Lazy loading speeds up application load time by splitting the application\n * into multiple bundles and loading them on demand.\n * To use lazy loading, provide the `loadChildren` property  instead of the `children` property.\n *\n * Given the following example route, the router will lazy load\n * the associated module on demand using the browser native import system.\n *\n * ```\n * [{\n *   path: 'lazy',\n *   loadChildren: () => import('./lazy-route/lazy.module').then(mod => mod.LazyModule),\n * }];\n * ```\n *\n * \\@publicApi\n * @record\n */\nfunction Route() { }\nif (false) {}\nclass LoadedRouterConfig {\n    /**\n     * @param {?} routes\n     * @param {?} module\n     */\n    constructor(routes, module) {\n        this.routes = routes;\n        this.module = module;\n    }\n}\nif (false) {}\n/**\n * @param {?} config\n * @param {?=} parentPath\n * @return {?}\n */\nfunction validateConfig(config, parentPath = '') {\n    // forEach doesn't iterate undefined values\n    for (let i = 0; i < config.length; i++) {\n        /** @type {?} */\n        const route = config[i];\n        /** @type {?} */\n        const fullPath = getFullPath(parentPath, route);\n        validateNode(route, fullPath);\n    }\n}\n/**\n * @param {?} route\n * @param {?} fullPath\n * @return {?}\n */\nfunction validateNode(route, fullPath) {\n    if (!route) {\n        throw new Error(`\n      Invalid configuration of route '${fullPath}': Encountered undefined route.\n      The reason might be an extra comma.\n\n      Example:\n      const routes: Routes = [\n        { path: '', redirectTo: '/dashboard', pathMatch: 'full' },\n        { path: 'dashboard',  component: DashboardComponent },, << two commas\n        { path: 'detail/:id', component: HeroDetailComponent }\n      ];\n    `);\n    }\n    if (Array.isArray(route)) {\n        throw new Error(`Invalid configuration of route '${fullPath}': Array cannot be specified`);\n    }\n    if (!route.component && !route.children && !route.loadChildren &&\n        (route.outlet && route.outlet !== PRIMARY_OUTLET)) {\n        throw new Error(`Invalid configuration of route '${fullPath}': a componentless route without children or loadChildren cannot have a named outlet set`);\n    }\n    if (route.redirectTo && route.children) {\n        throw new Error(`Invalid configuration of route '${fullPath}': redirectTo and children cannot be used together`);\n    }\n    if (route.redirectTo && route.loadChildren) {\n        throw new Error(`Invalid configuration of route '${fullPath}': redirectTo and loadChildren cannot be used together`);\n    }\n    if (route.children && route.loadChildren) {\n        throw new Error(`Invalid configuration of route '${fullPath}': children and loadChildren cannot be used together`);\n    }\n    if (route.redirectTo && route.component) {\n        throw new Error(`Invalid configuration of route '${fullPath}': redirectTo and component cannot be used together`);\n    }\n    if (route.path && route.matcher) {\n        throw new Error(`Invalid configuration of route '${fullPath}': path and matcher cannot be used together`);\n    }\n    if (route.redirectTo === void 0 && !route.component && !route.children && !route.loadChildren) {\n        throw new Error(`Invalid configuration of route '${fullPath}'.

Available options are:\n *  - `'merge'`: merge the queryParams into the current queryParams\n *  - `'preserve'`: preserve the current queryParams\n *  - default/`''`: use the queryParams only\n *\n * Same options for {\\@link NavigationExtras#queryParamsHandling\n * NavigationExtras#queryParamsHandling}.\n *\n * ```\n * <a [routerLink]=\"['/user/bob']\" [queryParams]=\"{debug: true}\" queryParamsHandling=\"merge\">\n *   link to user component\n * </a>\n * ```\n *\n * You can provide a `state` value to be persisted to the browser's History.state\n * property (See https://developer.mozilla.org/en-US/docs/Web/API/History#Properties). It's\n * used as follows:\n *\n * ```\n * <a [routerLink]=\"['/user/bob']\" [state]=\"{tracingId: 123}\">\n *   link to user component\n * </a>\n * ```\n *\n * And later the value can be read from the router through `router.getCurrentNavigation`.\n * For example, to capture the `tracingId` above during the `NavigationStart` event:\n *\n * ```\n * // Get NavigationStart events\n * router.events.pipe(filter(e => e instanceof NavigationStart)).subscribe(e => {\n *   const navigation = router.getCurrentNavigation();\n *   tracingService.trace({id: navigation.extras.state.tracingId});\n * });\n * ```\n *\n * The router link directive always treats the provided input as a delta to the current url.\n *\n * For instance, if the current url is `/user/(box//aux:team)`.\n *\n * Then the following link `<a [routerLink]=\"['/user/jim']\">Jim</a>` will generate the link\n * `/user/(jim//aux:team)`.\n *\n * See {\\@link Router#createUrlTree createUrlTree} for more information.\n *\n * \\@ngModule RouterModule\n *\n * \\@publicApi\n */\nclass RouterLink {\n    /**\n     * @param {?} router\n     * @param {?} route\n     * @param {?} tabIndex\n     * @param {?} renderer\n     * @param {?} el\n     */\n    constructor(router, route, tabIndex, renderer, el) {\n        this.router = router;\n        this.route = route;\n        this.commands = [];\n        if (tabIndex == null) {\n            renderer.setAttribute(el.nativeElement, 'tabindex', '0');\n        }\n    }\n    /**\n     * @param {?} commands\n     * @return {?}\n     */\n    set routerLink(commands) {\n        if (commands != null) {\n            this.commands = Array.isArray(commands) ?

animation trigger in the `animations` section of `\\@Component` metadata.\n     * In the template, reference the trigger by name and bind it to a trigger expression that\n     * evaluates to a defined animation state, using the following format:\n     *\n     * `[\\@triggerName]=\"expression\"`\n     *\n     * Animation trigger bindings convert all values to strings, and then match the\n     * previous and current values against any linked transitions.\n     * Booleans can be specified as `1` or `true` and `0` or `false`.\n     *\n     * ### Usage Example\n     *\n     * The following example creates an animation trigger reference based on the provided\n     * name value.\n     * The provided animation value is expected to be an array consisting of state and\n     * transition declarations.\n     *\n     * ```typescript\n     * \\@Component({\n     *   selector: \"my-component\",\n     *   templateUrl: \"my-component-tpl.html\",\n     *   animations: [\n     *     trigger(\"myAnimationTrigger\", [\n     *       state(...),\n     *       state(...),\n     *       transition(...),\n     *       transition(...)\n     *     ])\n     *   ]\n     * })\n     * class MyComponent {\n     *   myStatusExp = \"something\";\n     * }\n     * ```\n     *\n     * The template associated with this component makes use of the defined trigger\n     * by binding to an element within its template code.\n     *\n     * ```html\n     * <!-- somewhere inside of my-component-tpl.html -->\n     * <div [\\@myAnimationTrigger]=\"myStatusExp\">...</div>\n     * ```\n     *\n     * ### Using an inline function\n     * The `transition` animation method also supports reading an inline function which can decide\n     * if its associated animation should be run.\n     *\n     * ```typescript\n     * // this method is run each time the `myAnimationTrigger` trigger value changes.\n     * function myInlineMatcherFn(fromState: string, toState: string, element: any, params: {[key:\n     * string]: any}): boolean {\n     *   // notice that `element` and `params` are also available here\n     *   return toState == 'yes-please-animate';\n     * }\n     *  /\n     *   selector: 'my-component',\n     *   templateUrl: 'my-component-tpl.html',\n     *   animations: [\n     *     trigger('myAnimationTrigger', [\n     *       transition(myInlineMatcherFn, [\n     *         // the animation sequence code\n     *       ]),\n     *     ])\n     *   ]\n     * })\n     * class MyComponent {\n     *   myStatusExp = \"yes-please-animate\";\n     * }\n     * ```\n     *\n     * ### Disabling Animations\n     * When true, the special animation control binding `\\@.disabled` binding prevents\n     * all animations from rendering.\n     * Place the  `\\@.disabled` binding on an element to disable\n     * animations on the element itself, as well as any inner animation triggers\n     * within the element.\n     *\n     * The following example shows how to use this feature:\n     *\n     * ```typescript /\n     *   selector: 'my-component',\n     *   template: `\n     *     <div [\\@.disabled]=\"isDisabled\">\n     *       <div [\\@childAnimation]=\"exp\"></div>\n     *     </div>\n     *   `,\n     *   animations: [\n     *     trigger(\"childAnimation\", [\n     *       // ...\n     *     ])\n     *   ]\n     * })\n     * class MyComponent {\n     *   isDisabled = true;\n     *   exp = '...';\n     * }\n     * ```\n     *\n     * When `\\@.disabled` is true, it prevents the `\\@childAnimation` trigger from animating,\n     * along with any inner animations.\n     *\n     * ### Disable animations application-wide\n     * When an area of the template is set to have animations disabled,\n     * **all** inner components have their animations disabled as well.\n     * This means that you can disable all animations for an app\n     * by placing a host binding set on `\\@.disabled` on the topmost Angular component.\n     *\n     * ```typescript\n     * import {Component, HostBinding} from '\\@angular/core';\n     *  /\n     *   selector: 'app-component',\n     *   templateUrl: 'app.component.html',\n     * })\n     * class AppComponent {\n     * \\@HostBinding('@.disabled')\n     *   public animationsDisabled = true;\n     * }\n     * ```\n     *\n     * ### Overriding disablement of inner animations\n     * Despite inner animations being disabled, a parent animation can `query()`\n     * for inner elements located in disabled areas of the template and still animate\n     * them if needed.

Angular automatically adds or removes\n     * CSS styles to ensure that the element is in the correct final state.\n     *\n     * The following example defines a transition that starts by hiding the element,\n     * then makes sure that it animates properly to whatever state is currently active for trigger:\n     *\n     * ```typescript\n     * transition(\"void => *\", [\n     *   style({ opacity: 0 }),\n     *   animate(500)\n     *  ])\n     * ```\n     * ### Boolean value matching\n     * If a trigger binding value is a Boolean, it can be matched using a transition expression\n     * that compares true and false or 1 and 0. For example:\n     *\n     * ```\n     * // in the template\n     * <div [\\@openClose]=\"open ? true : false\">...</div>\n     * // in the component metadata\n     * trigger('openClose', [\n     *   state('true', style({ height: '*' })),\n     *   state('false', style({ height: '0px' })),\n     *   transition('false <=> true', animate(500))\n     * ])\n     * ```\n     *\n     * \\@publicApi\n     *\n     * @param {?} stateChangeExpr A Boolean expression or function that compares the previous and current\n     * animation states, and returns true if this transition should occur.

The way in which this occurs is that\n     * each time a style property is examined, a string-map containing the property will be updated with\n     * the start and end times for when the property is used within an animation step.\n     *\n     * If there are two or more parallel animations that are currently running (these are invoked by the\n     * group()) on the same element then the validator will throw an error. Since the start/end timing\n     * values are collected for each property then if the current animation step is animating the same\n     * property and its timing values fall anywhere into the window of time that the property is\n     * currently being animated within then this is what causes an error.\n     *\n     * 2. Timing values\n     * The validator will validate to see if a timing value of `duration delay easing` or\n     * `durationNumber` is valid or not.\n     *\n     * (note that upon validation the code below will replace the timing data with an object containing\n     * {duration,delay,easing}.\n     *\n     * 3. Offset Validation\n     * Each of the style() calls are allowed to have an offset value when placed inside of keyframes().\n     * Offsets within keyframes() are considered valid when:\n     *\n     *   - No offsets are used at all\n     *   - Each style() entry contains an offset value\n     *   - Each offset is between 0 and 1\n     *   - Each offset is greater to or equal than the previous one\n     *\n     * Otherwise an error will be thrown.\n     */\n\n    /**\n     * @param {?} driver\n     * @param {?} metadata\n     * @param {?} errors\n     * @return {?}\n     */\n\n    function

   *\n     * For this operation to cover the combination of animation verbs (style, animate, group, etc...) a\n     * combination of prototypical inheritance, AST traversal and merge-sort-like algorithms are used.\n     *\n     * [AST Traversal]\n     * Each of the animation verbs, when executed, will return an string-map object representing what\n     * type of action it is (style, animate, group, etc...) and the data associated with it. This means\n     * that when functional composition mix of these functions is evaluated (like in the example above)\n     * then it will end up producing a tree of objects representing the animation itself.\n     *\n     * When this animation object tree is processed by the visitor code below it will visit each of the\n     * verb statements within the visitor. And during each visit it will build the context of the\n     * animation keyframes by interacting with the `TimelineBuilder`.\n     *\n     * [TimelineBuilder]\n     * This class is responsible for tracking the styles and building a series of keyframe objects for a\n     * timeline between a start and end time. The builder starts off with an initial timeline and each\n     * time the AST comes across a `group()`, `keyframes()` or a combination of the two wihtin a\n     * `sequence()` then it will generate a sub timeline for each step as well as a new one after\n     * they are complete.\n     *\n     * As the AST is traversed, the timing state on each of the timelines will be incremented. If a sub\n     * timeline was created (based on one of the cases above) then the parent timeline will attempt to\n     * merge the styles used within the sub timelines into itself (only with group() this will happen).\n     * This happens with a merge operation (much like how the merge works in mergesort) and it will only\n     * copy the most recently used styles from the sub timelines into the parent timeline. This ensures\n     * that if the styles are used later on in another phase of the animation then they will be the most\n     * up-to-date values.\n     *\n     * [How Missing Styles Are Updated]\n     * Each timeline has a `backFill` property which is responsible for filling in new styles into\n     * already processed keyframes if a new style shows up later within the animation sequence.\n     *\n     * ```\n     * sequence([\n     *   style({ width: 0 }),\n     *   animate(1000, style({ width: 100 })),\n     *   animate(1000, style({ width: 200 })),\n     *   animate(1000, style({ width: 300 }))\n     *   animate(1000, style({ width: 400, height: 400 })) // notice how `height` doesn't exist anywhere\n     * else\n     * ])\n     * ```\n     *\n     * What is happening here is that the `height` value is added later in the sequence, but is missing\n     * from all previous animation steps. Therefore when a keyframe is created it would also be missing\n     * from all previous keyframes up until where it is first used. For the timeline keyframe generation\n     * to properly fill in the style it will place the previous value (the value from the parent\n     * timeline) or a default value of `*` into the backFill object. Given that each of the keyframe\n     * styles are objects that prototypically inhert from the backFill object, this means that if a\n     * value is added into the backFill then it will automatically propagate any missing values to all\n     * keyframes. Therefore the missing `height` value will be properly filled into the already\n     * processed keyframes.\n     *\n     * When a sub-timeline is created it will have its own backFill property. This is done so that\n     * styles present within the sub-timeline do not accidentally seep into the previous/future timeline\n     * keyframes\n     *\n     * (For prototypically-inherited contents to be detected a `for(i in obj)` loop must be used.)\n     *\n     * [Validation]\n     * The code in this file is not responsible for validation. That functionality happens with within\n     * the `AnimationValidatorVisitor` code.\n     */\n\n    /**\n     * @param {?} driver\n     * @param {?} rootElement\n     * @param {?} ast\n     * @param {?} enterClassName\n     * @param {?} leaveClassName\n     * @param {?=} startingStyles\n     * @param {?=} finalStyles\n     * @param {?=} options\n     * @param {?=} subInstructions\n     * @param {?=} errors\n     * @return {?}\n     */\n\n    function buildAnimationTimelines(driver, rootElement, ast, enterClassName, leaveClassName) {\n      var startingStyles = arguments.length > 5 && arguments[5] !== undefined ?

form](guide/structural-directives#the-asterisk--prefix) `*ngFor`.\n     * In this form, the template to be rendered for each iteration is the content\n     * of an anchor element containing the

as i; trackBy: trackByFn\">...</li>\n     * ```\n     *\n     * The shorthand form expands into a long form that uses the `ngForOf` selector\n     * on an `<ng-template>` element.\n     * The content

the shorthand syntax as it compiles the template.\n     * The context for each embedded view is logically merged to the current component\n     * context according to its lexical position.\n     *\n     * When using the shorthand syntax, Angular allows only [one structural directive\n     * on an element](guide/structural-directives#one-structural-directive-per-host-element).\n     * If you want to iterate conditionally, for example,\n     * put the `*ngIf` on a container element that wraps the `*ngFor` element.\n     * For futher discussion, see\n     * [Structural Directives](guide/structural-directives#one-per-element).\n     *\n     * \\@usageNotes\n     *\n     * ### Local variables\n     *\n     * `NgForOf` provides exported values that can be aliased to local variables.\n     * For example:\n     *\n     *  ```\n     * <li *ngFor=\"let user of userObservable | async as users; index as i; first as isFirst\">\n     *    {{i}}/{{users.length}}. {{user}} <span *ngIf=\"isFirst\">default</span>\n     * </li>\n     * ```\n     *\n     * The following exported values can be aliased to local variables:\n     *\n     * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).\n     * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is\n     * more complex then a property access, for example when using the async pipe (`userStreams |\n     * async`).\n     * - `index: number`: The index of the current item in the iterable.\n     * - `first: boolean`: True when the item is the first item in the iterable.\n     * - `last: boolean`: True when the item is the last item in the iterable.\n     * - `even: boolean`: True when the item has an even index in the iterable.\n     * - `odd: boolean`: True when the item has an odd index in the iterable.\n     *\n     * ### Change propagation\n     *\n     * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:\n     *\n     * * When an item is added, a new instance of the template is added to the DOM.\n     * * When an item is removed, its template instance is removed from the DOM.\n     * * When items are reordered, their respective templates are reordered in the DOM.\n     *\n     * Angular uses object identity to track insertions and deletions within the iterator and reproduce\n     * those changes in the DOM. This has important implications for animations and any stateful\n     * controls that are present, such as `<input>` elements that accept user input. Inserted rows can\n     * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state\n     * such as user input.\n     * For more on animations, see [Transitions and Triggers](guide/transition-and-triggers).\n     *\n     * The identities of elements in the iterator can change while the data does not.\n     * This can happen, for example, if the iterator is produced from an RPC to the server, and that\n     * RPC is re-run. Even if the data hasn't changed, the second response produces objects with\n     * different identities, and Angular must tear down the entire DOM and rebuild it (as if all old\n     * elements were deleted and all new elements inserted).\n     *\n     * To avoid this expensive operation, you can customize the default tracking algorithm.\n     * by supplying the `trackBy` option to `NgForOf`.\n     * `trackBy` takes a function that has two arguments: `index` and `item`.\n     * If `trackBy` is given, Angular tracks changes by the return value of the function.\n     *\n     * @see [Structural Directives](guide/structural-directives)\n     * \\@ngModule CommonModule\n     * \\@publicApi\n     * @template T\n     */\n\n\n    var NgForOf =\n    /*#__PURE__*/\n    function () {\n      /**\n       * @param {?} _viewContainer\n       * @param {?} _template\n       * @param {?} _differs\n       */\n      function NgForOf(_viewContainer, _template, _differs) {\n        _classCallCheck(this, NgForOf);\n\n        this._viewContainer = _viewContainer;\n        this._template = _template;\n        this._differs = _differs;\n        this._ngForOfDirty = true;\n        this._differ = null;\n      }\n      /**\n       * The value of the iterable expression, which can be used as a\n       * [template input variable](guide/structural-directives#template-input-variable).\n       * @param {?} ngForOf\n       * @return {?}\n       */\n\n\n      _createClass2(NgForOf, [{\n        key: \"ngDoCheck\",\n\n        /**\n         * Applies the changes when needed.\n         * @return {?}\n         */\n        value: function ngDoCheck() {\n          if (this._ngForOfDirty) {\n            this._ngForOfDirty = false; // React on ngForOf changes only once all inputs have been initialized\n\n            /** @type {?} */\n\n            var value = this._ngForOf;\n\n            if (!this._differ && value) {\n              try {\n                this._differ = this._differs.find(value).create(this.ngForTrackBy);\n              } catch (_a) {\n                throw new Error(\"Cannot find a differ supporting object '\".concat(value, \"' of type '\").concat(getTypeName(value), \"'.

You can also specify a template that is defined\n     * externally, by referencing a labeled `<ng-template>` element. When you do this, you can\n     * change which template to use at runtime, as shown in the following example.\n     *\n     * {\\@example common/ngIf/ts/module.ts region='NgIfThenElse'}\n     *\n     * ### Storing a conditional result in a variable\n     *\n     * You might want to show a set of properties from the same object. If you are waiting\n     * for asynchronous data, the object can be undefined.\n     * In this case, you can use `ngIf` and store the result of the condition in a local\n     * variable as shown in the the following example.\n     *\n     * {\\@example common/ngIf/ts/module.ts region='NgIfAs'}\n     *\n     * This code uses only one `AsyncPipe`, so only one subscription is created.\n     * The conditional statement stores the result of `userStream|async` in the local variable `user`.\n     * You can then bind the local `user` repeatedly.\n     *\n     * The conditional displays the data only if `userStream` returns a value,\n     * so you don't need to use the\n     * [safe-navigation-operator](guide/template-syntax#safe-navigation-operator) (`?.`)\n     * to guard against null values when accessing properties.\n     * You can display an alternative template while waiting for the data.\n     *\n     * ### Shorthand syntax\n     *\n     * The shorthand syntax `*ngIf` expands into two separate template specifications\n     * for the \"then\" and \"else\" clauses. For example, consider the following shorthand statement,\n     * that is meant to show a loading page while waiting for data to be loaded.\n     *\n     * ```\n     * <div class=\"hero-list\" *ngIf=\"heroes else loading\">\n     *  ...\n     * </div>\n     *\n     * <ng-template #loading>\n     *  <div>Loading...</div>\n     * </ng-template>\n     * ```\n     *\n     * You can see that the \"else\" clause references the `<ng-template>`\n     * with the `#loading` label, and the template for the \"then\" clause\n     * is provided as the content of the anchor element.\n     *\n     * However, when Angular expands the shorthand syntax, it creates\n     * another `<ng-template>` tag, with `ngIf` and `ngIfElse` directives.\n     * The anchor element containing the template for the \"then\" clause becomes\n     * the content of this unlabeled `<ng-template>` tag.\n     *\n     * ```\n     * <ng-template [ngIf]=\"hero-list\" [ngIfElse]=\"loading\">\n     *  <div class=\"hero-list\">\n     *   ...\n     *  </div>\n     * </ng-template>\n     *\n     * <ng-template #loading>\n     *  <div>Loading...</div>\n     * </ng-template>\n     * ```\n     *\n     * The presence of the implicit template object has implications for the nesting of\n     * structural directives.

The goal is to allow users to avoid the\n      most obvious pitfalls and do so without compromising performance significantly.\n      For ShadowDOM styling that's not covered here, a set of best practices\n      can be provided that should allow users to accomplish more complex styling.\n    \n      The following is a list of specific ShadowDOM styling features and a brief\n      discussion of the approach used to shim.\n    \n      Shimmed features:\n    \n      * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host\n      element using the :host rule. To shim this feature, the :host styles are\n      reformatted and prefixed with a given scope name and promoted to a\n      document level stylesheet.\n      For example, given a scope name of .foo, a rule like this:\n    \n        :host {\n            background: red;\n          }\n        }\n    \n      becomes:\n    \n        .foo {\n          background: red;\n        }\n    \n      * encapsulation: Styles defined within ShadowDOM, apply only to\n      dom inside the ShadowDOM. Polymer uses one of two techniques to implement\n      this feature.\n    \n      By default, rules are prefixed with the host element tag name\n      as a descendant selector. This ensures styling does not leak out of the 'top'\n      of the element's ShadowDOM. For example,\n    \n      div {\n          font-weight: bold;\n        }\n    \n      becomes:\n    \n      x-foo div {\n          font-weight: bold;\n        }\n    \n      becomes:\n    \n    \n      Alternatively, if WebComponents.ShadowCSS.strictStyling is set to true then\n      selectors are scoped by adding an attribute selector suffix to each\n      simple selector that contains the host element tag name. Each element\n      in the element's ShadowDOM template is also given the scope attribute.\n      Thus, these rules match only elements that have the scope attribute.\n      For example, given a scope name of x-foo, a rule like this:\n    \n        div {\n          font-weight: bold;\n        }\n    \n      becomes:\n    \n        div[x-foo] {\n          font-weight: bold;\n        }\n    \n      Note that elements that are dynamically added to a scope must have the scope\n      selector added to them manually.\n    \n      * upper/lower bound encapsulation: Styles which are defined outside a\n      shadowRoot should not cross the ShadowDOM boundary and should not apply\n      inside a shadowRoot.\n    \n      This styling behavior is not emulated. Some possible ways to do this that\n      were rejected due to complexity and/or performance concerns include: (1) reset\n      every possible property for every possible selector for a given scope name;\n      (2) re-implement css in javascript.\n    \n      As an alternative, users should make sure to use selectors\n      specific to the scope in which they are working.\n    \n      * ::distributed: This behavior is not emulated. It's often not necessary\n      to style the contents of a specific insertion point and instead, descendants\n      of the host element can be styled selectively. Users can also create an\n      extra node around an insertion point and style that node's contents\n      via descendent selectors. For example, with a shadowRoot like this:\n    \n        <style>\n          ::content(div) {\n            background: red;\n          }\n        </style>\n        <content></content>\n    \n      could become:\n    \n        <style>\n          / *@polyfill .content-container div * /\n          ::content(div) {\n            background: red;\n          }\n        </style>\n        <div class=\"content-container\">\n          <content></content>\n        </div>\n    \n      Note the use of @polyfill in the comment above a ShadowDOM specific style\n      declaration. This is a directive to the styling shim to use the selector\n      in comments in lieu of the next selector when running under polyfill.\n    */\n\n\n    var ShadowCss =\n    /*#__PURE__*/\n    function () {\n      function ShadowCss() {\n        _classCallCheck(this, ShadowCss);\n\n        this.strictStyling = true;\n      }\n      /*\n      * Shim some cssText with the given selector.

The `StylingMapArray` instance is stored in the binding location\n     * where the `BINDING_INDEX` is situated when the `styleMap()` or `classMap()`\n     * instruction were called. Once the binding changes, then the internal `bitMask`\n     * value is marked as dirty.\n     *\n     * Styling values are applied once CD exits the element (which happens when\n     * the `select(n)` instruction is called or the template function exits). When\n     * this occurs, all prop-based bindings are applied. If a map-based binding is\n     * present then a special flushing function (called a sync function) is made\n     * available and it will be called each time a styling property is flushed.\n     *\n     * The flushing algorithm is designed to apply styling for a property (which is\n     * a CSS property or a className value) one by one. If map-based bindings\n     * are present, then the flushing algorithm will keep calling the maps styling\n     * sync function each time a property is visited. This way, the flushing\n     * behavior of map-based bindings will always be at the same property level\n     * as the current prop-based property being iterated over (because everything\n     * is alphabetically sorted).\n     *\n     * Let's imagine we have the following HTML template code:\n     *\n     * ```html\n     * <div [style]=\"{width:'100px', height:'200px', 'z-index':'10'}\"\n     *      [style.width.px]=\"200\">...</div>\n     * ```\n     *\n     * When CD occurs, both the `[style]` and `[style.width]` bindings\n     * are evaluated. Then when the styles are flushed on screen, the\n     * following operations happen:\n     *\n     * 1. `[style.width]` is attempted to be written to the element.\n     *\n     * 2.  Once that happens, the algorithm instructs the map-based\n     *     entries (`[style]` in this case) to \"catch up\" and apply\n     *     all values up to the `width` value. When this happens the\n     *     `height` value is applied to the element (since it is\n     *     alphabetically situated before the `width` property).\n     *\n     * 3. Since there are no more prop-based entries anymore, the\n     *    loop exits and then, just before the flushing ends, it\n     *    instructs all map-based bindings to \"finish up\" applying\n     *    their values.\n     *\n     * 4. The only remaining value within the map-based entries is\n     *    the `z-index` value (`width` got skipped because it was\n     *    successfully applied via the prop-based `[style.width]`\n     *    binding). Since all map-based entries are told to \"finish up\",\n     *    the `z-index` value is iterated over and it is then applied\n     *    to the element.\n     *\n     * The most important thing to take note of here is that prop-based\n     * bindings are evaluated in order alongside map-based bindings.\n     * This allows all styling across an element to be applied in O(n)\n     * time (a similar algorithm is that of the array merge algorithm\n     * in merge sort).\n     * @type {?}\n     */\n\n\n    var syncStylingMap =\n    /**\n    * @param {?} context\n    * @param {?} renderer\n    * @param {?} element\n    * @param {?} data\n    * @param {?} applyStylingFn\n    * @param {?} sanitizer\n    * @param {?} mode\n    * @param {?=} targetProp\n    * @param {?=} defaultValue\n    * @return {?}\n    */\n    function syncStylingMap(context, renderer, element, data, applyStylingFn, sanitizer, mode, targetProp, defaultValue) {\n      /** @type {?} */\n      var targetPropValueWasApplied = false; // once the map-based styling code is activate it is never deactivated.

This\n    // ensure that despite being called recursively or after picking up after an\n    // exception, the ngAfterContentInit or ngAfterViewInit will be called on the\n    // correct nodes.

Since number of calls to ngAfterContentInit and ngAfterViewInit\n    // are stable (will be the same for the same view regardless of exceptions or\n    // recursion) we just need to count them which will roughly correspond to the\n    // post-order index (it skips elements and directives that do not have\n    // lifecycle hooks).\n    //\n    // For example, if an exception is raised in the E6.onAfterViewInit() the\n    // initIndex is left at 3 (by shouldCallLifecycleInitHook() which set it to\n    // initIndex + 1). When checkAndUpdateView() is called again D3, E2 and E6 will\n    // not have their ngAfterViewInit() called but, starting with E7, the rest of\n    // the view will begin getting ngAfterViewInit() called until a check and\n    // pass is complete.\n    //\n    // This algorthim also handles recursion. Consider if E4's ngAfterViewInit()\n    // indirectly calls E1's ChangeDetectorRef.detectChanges(). The expected\n    // initIndex is set to 6, the recusive checkAndUpdateView() starts walk again.\n    // D3, E2, E6, E7, E5 and E4 are skipped, ngAfterViewInit() is called on E1.\n    // When the recursion returns the initIndex will be 7 so E1 is skipped as it\n    // has already been called in the recursively called checkAnUpdateView().\n\n    /**\n     * @param {?} view\n     * @param {?} lifecycles\n     * @return {?}\n     */\n\n\n    function callLifecycleHooksChildrenFirst(view, lifecycles) {\n      if (!(view.def.nodeFlags & lifecycles)) {\n        return;\n      }\n      /** @type {?} */\n\n\n      var nodes = view.def.nodes;\n      /** @type {?} */\n\n      var initIndex = 0;\n\n      for (var i = 0;

caveats\n     *\n     * Note two important points about `isStable`, demonstrated in the examples below:\n     * - the application will never be stable if you start any kind\n     * of recurrent asynchronous task when the application starts\n     * (for example for a polling process, started with a `setInterval`, a `setTimeout`\n     * or using RxJS operators like `interval`);\n     * - the `isStable` Observable runs outside of the Angular zone.\n     *\n     * Let's imagine that you start a recurrent task\n     * (here incrementing a counter, using RxJS `interval`),\n     * and at the same time subscribe to `isStable`.\n     *\n     * ```\n     * constructor(appRef: ApplicationRef) {\n     *   appRef.isStable.pipe(\n     *      filter(stable => stable)\n     *   ).subscribe(() => console.log('App is stable now');\n     *   interval(1000).subscribe(counter => console.log(counter));\n     * }\n     * ```\n     * In this example, `isStable` will never emit `true`,\n     * and the trace \"App is stable now\" will never get logged.\n     *\n     * If you want to execute something when the app is stable,\n     * you have to wait for the application to be stable\n     * before starting your polling process.\n     *\n     * ```\n     * constructor(appRef: ApplicationRef) {\n     *   appRef.isStable.pipe(\n     *     first(stable => stable),\n     *     tap(stable => console.log('App is stable now')),\n     *     switchMap(() => interval(1000))\n     *   ).subscribe(counter => console.log(counter));\n     * }\n     * ```\n     * In this example, the trace \"App is stable now\" will be logged\n     * and then the counter starts incrementing every second.\n     *\n     * Note also that this Observable runs outside of the Angular zone,\n     * which means that the code in the subscription\n     * to this Observable will not trigger the change detection.\n     *\n     * Let's imagine that instead of logging the counter value,\n     * you update a field of your component\n     * and display it in its template.\n     *\n     * ```\n     * constructor(appRef: ApplicationRef) {\n     *   appRef.isStable.pipe(\n     *     first(stable => stable),\n     *     switchMap(() => interval(1000))\n     *   ).subscribe(counter => this.value = counter);\n     * }\n     * ```\n     * As the `isStable` Observable runs outside the zone,\n     * the `value` field will be updated properly,\n     * but the template will not be refreshed!\n     *\n     * You'll have to manually trigger the change detection to update the template.\n     *\n     * ```\n     * constructor(appRef: ApplicationRef, cd: ChangeDetectorRef) {\n     *   appRef.isStable.pipe(\n     *     first(stable => stable),\n     *     switchMap(() => interval(1000))\n     *   ).subscribe(counter => {\n     *     this.value = counter;\n     *     cd.detectChanges();\n     *   });\n     * }\n     * ```\n     *\n     * Or make the subscription callback run inside the zone.\n     *\n     * ```\n     * constructor(appRef: ApplicationRef, zone: NgZone) {\n     *   appRef.isStable.pipe(\n     *     first(stable => stable),\n     *     switchMap(() => interval(1000))\n     *

It's possible for the identities of items\n     * to change while the data does not. This can happen, for example, if the items are produced\n     * from an RPC to the server, and that RPC is re-run. Even if the data hasn't changed, the\n     * second response will produce objects with different identities.\n     *\n     * To customize the default option comparison algorithm, `<select>` supports `compareWith` input.\n     * `compareWith` takes a **function** which has two arguments: `option1` and `option2`.\n     * If `compareWith` is given, Angular selects option by the return value of the function.\n     *\n     * ```ts\n     * const selectedCountriesControl = new FormControl();\n     * ```\n     *\n     * ```\n     * <select [compareWith]=\"compareFn\"  [formControl]=\"selectedCountriesControl\">\n     *     <option *ngFor=\"let country of countries\" [ngValue]=\"country\">\n     *         {{country.name}}\n     *     </option>\n     * </select>\n     *\n     * compareFn(c1: Country, c2: Country): boolean {\n     *     return c1 && c2 ? c1.id === c2.id : c1 === c2;\n     * }\n     * ```\n     *\n     * **Note:** We listen to the 'change' event because 'input' events aren't fired\n     * for selects in Firefox and IE:\n     * https://bugzilla.mozilla.org/show_bug.cgi?id=1024350\n     * https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/4660045/\n     *\n     * \\@ngModule ReactiveFormsModule\n     * \\@ngModule FormsModule\n     * \\@publicApi\n     */\n\n\n    var SelectControlValueAccessor =\n    /*#__PURE__*/\n    function () {\n      /**\n       * @param {?} _renderer\n       * @param {?} _elementRef\n       */\n      function SelectControlValueAccessor(_renderer, _elementRef) {\n        _classCallCheck(this, SelectControlValueAccessor);\n\n        this._renderer = _renderer;\n        this._elementRef = _elementRef;\n        /**\n         * \\@internal\n         */\n\n        this._optionMap = new Map();\n        /**\n         * \\@internal\n         */\n\n        this._idCounter = 0;\n        /**\n         * \\@description\n         * The registered callback function called when a change event occurs on the input element.\n         */\n\n        this.onChange =\n        /**\n        * @param {?} _\n        * @return {?}\n        */\n        function (_) {};\n        /**\n         * \\@description\n         * The registered callback function called when a blur event occurs on the input element.\n         */\n\n\n        this.onTouched =\n        /**\n        * @return {?}\n        */\n        function () {};\n\n        this._compareWith = _angular_core__WEBPACK_IMPORTED_MODULE_0__[\"ɵlooseIdentical\"];\n      }\n      /**\n       * \\@description\n       * Tracks the option comparison algorithm for tracking identities when\n       * checking for changes.\n       * @param {?} fn\n       * @return {?}\n       */\n\n\n      _createClass2(SelectControlValueAccessor, [{\n        key: \"writeValue\",\n\n        /**\n         * Sets the \"value\" property on the input element.

Support for using the `ngModel` input property and `ngModelChange` event with reactive\n     * form directives has been deprecated in Angular v6 and will be removed in Angular v7.\n     *\n     * Now deprecated:\n     *\n     * ```html\n     * <input [formControl]=\"control\" [(ngModel)]=\"value\">\n     * ```\n     *\n     * ```ts\n     * this.value = 'some value';\n     * ```\n     *\n     * This has been deprecated for a few reasons. First, developers have found this pattern\n     * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's\n     * an input/output property named `ngModel` on the reactive form directive that simply\n     * approximates (some of) its behavior. Specifically, it allows getting/setting the value\n     * and intercepting value events. However, some of `ngModel`'s other features - like\n     * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,\n     * which has understandably caused some confusion.\n     *\n     * In addition, this pattern mixes template-driven and reactive forms strategies, which\n     * we generally don't recommend because it doesn't take advantage of the full benefits of\n     * either strategy. Setting the value in the template violates the template-agnostic\n     * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in\n     * the class removes the convenience of defining forms in the template.\n     *\n     * To update your code before v7, you'll want to decide whether to stick with reactive form\n     * directives (and get/set values using reactive forms patterns) or switch over to\n     * template-driven directives.\n     *\n     * After (choice 1 - use reactive forms):\n     *\n     * ```html\n     * <input [formControl]=\"control\">\n     * ```\n     *\n     * ```ts\n     * this.control.setValue('some value');\n     * ```\n     *\n     * After (choice 2 - use template-driven forms):\n     *\n     * ```html\n     * <input [(ngModel)]=\"value\">\n     * ```\n     *\n     * ```ts\n     * this.value = 'some value';\n     * ```\n     *\n     * By default, when you use this pattern, you will see a deprecation warning once in dev\n     * mode. You can choose to silence this warning by providing a config for\n     * `ReactiveFormsModule` at import time:\n     *\n     * ```ts\n     * imports: [\n     *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'});\n     * ]\n     * ```\n     *\n     * Alternatively, you can choose to surface a separate warning for each instance of this\n     * pattern with a config value of `\"always\"`. This may help to track down where in the code\n     * the pattern is being used as the code is being updated.\n     *\n     * \\@ngModule ReactiveFormsModule\n     * \\@publicApi\n     */\n\n    var FormControlDirective =\n    /*#__PURE__*/\n    function (_NgControl2) {\n      _inherits(FormControlDirective, _NgControl2);\n\n      /**\n       * @param {?} validators\n       * @param {?} asyncValidators\n       * @param {?} valueAccessors\n       * @param {?} _ngModelWarningConfig\n       */\n      function FormControlDirective(validators, asyncValidators, valueAccessors, _ngModelWarningConfig) {\n        var _this581;\n\n        _classCallCheck(this, FormControlDirective);\n\n        _this581 = _possibleConstructorReturn(this, _getPrototypeOf(FormControlDirective).call(this));\n        _this581._ngModelWarningConfig = _ngModelWarningConfig;\n        /**\n         * @deprecated as of v6\n         */\n\n        _this581.update = new _angular_core__WEBPACK_IMPORTED_MODULE_0__[\"EventEmitter\"]();\n        /**\n         * \\@description\n         * Instance property used to track whether an ngModel warning has been sent out for this\n         * particular `FormControlDirective` instance.

`RadioControlValueAccessor`\n     * * Selects: `SelectControlValueAccessor`\n     *\n     * ### Use with ngModel\n     *\n     * Support for using the `ngModel` input property and `ngModelChange` event with reactive\n     * form directives has been deprecated in Angular v6 and will be removed in Angular v7.\n     *\n     * Now deprecated:\n     *\n     * ```html\n     * <form [formGroup]=\"form\">\n     *   <input formControlName=\"first\" [(ngModel)]=\"value\">\n     * </form>\n     * ```\n     *\n     * ```ts\n     * this.value = 'some value';\n     * ```\n     *\n     * This has been deprecated for a few reasons. First, developers have found this pattern\n     * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's\n     * an input/output property named `ngModel` on the reactive form directive that simply\n     * approximates (some of) its behavior. Specifically, it allows getting/setting the value\n     * and intercepting value events. However, some of `ngModel`'s other features - like\n     * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,\n     * which has understandably caused some confusion.\n     *\n     * In addition, this pattern mixes template-driven and reactive forms strategies, which\n     * we generally don't recommend because it doesn't take advantage of the full benefits of\n     * either strategy. Setting the value in the template violates the template-agnostic\n     * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in\n     * the class removes the convenience of defining forms in the template.\n     *\n     * To update your code before v7, you'll want to decide whether to stick with reactive form\n     * directives (and get/set values using reactive forms patterns) or switch over to\n     * template-driven directives.\n     *\n     * After (choice 1 - use reactive forms):\n     *\n     * ```html\n     * <form [formGroup]=\"form\">\n     *   <input formControlName=\"first\">\n     * </form>\n     * ```\n     *\n     * ```ts\n     * this.form.get('first').setValue('some value');\n     * ```\n     *\n     * After (choice 2 - use template-driven forms):\n     *\n     * ```html\n     * <input [(ngModel)]=\"value\">\n     * ```\n     *\n     * ```ts\n     * this.value = 'some value';\n     * ```\n     *\n     * By default, when you use this pattern, you will see a deprecation warning once in dev\n     * mode. You can choose to silence this warning by providing a config for\n     * `ReactiveFormsModule` at import time:\n     *\n     * ```ts\n     * imports: [\n     *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'})\n     * ]\n     * ```\n     *\n     * Alternatively, you can choose to surface a separate warning for each instance of this\n     * pattern with a config value of `\"always\"`. This may help to track down where in the code\n     * the pattern is being used as the code is being updated.\n     *\n     * \\@ngModule ReactiveFormsModule\n     * \\@publicApi\n     */\n\n    var FormControlName =\n    /*#__PURE__*/\n    function (_NgControl3) {\n      _inherits(FormControlName, _NgControl3);\n\n      /**\n       * @param {?} parent\n       * @param {?} validators\n       * @param {?} asyncValidators\n       * @param {?} valueAccessors\n       * @param {?} _ngModelWarningConfig\n       */\n      function FormControlName(parent, validators, asyncValidators, valueAccessors, _ngModelWarningConfig) {\n        var _this587;\n\n        _classCallCheck(this, FormControlName);\n\n        _this587 = _possibleConstructorReturn(this, _getPrototypeOf(FormControlName).call(this));\n        _this587._ngModelWarningConfig = _ngModelWarningConfig;\n        _this587._added = false;\n        /**\n         * @deprecated as of v6\n         */\n\n        _this587.update = new _angular_core__WEBPACK_IMPORTED_MODULE_0__[\"EventEmitter\"]();\n        /**\n         * \\@description\n         * Instance property used to track whether an ngModel warning has been sent out for this\n         * particular FormControlName instance.

The 'Chat' component is placed into the 'aux' outlet.\n     *\n     * ```\n     * [{\n     *   path: 'team/:id',\n     *   component: Team\n     * }, {\n     *   path: 'chat/:user',\n     *   component: Chat\n     *   outlet: 'aux'\n     * }]\n     * ```\n     *\n     * ### Wild Cards\n     *\n     * The following route uses wild-card notation to specify a component\n     * that is always instantiated regardless of where you navigate to.\n     *\n     * ```\n     * [{\n     *   path: '**',\n     *   component: WildcardComponent\n     * }]\n     * ```\n     *\n     * ### Redirects\n     *\n     * The following route uses the `redirectTo` property to ignore a segment of\n     * a given URL when looking for a child path.\n     *\n     * When navigating to '/team/11/legacy/user/jim', the router changes the URL segment\n     * '/team/11/legacy/user/jim' to '/team/11/user/jim', and then instantiates\n     * the Team component with the User child component in it.\n     *\n     * ```\n     * [{\n     *   path: 'team/:id',\n     *   component: Team,\n     *   children: [{\n     *     path: 'legacy/user/:name',\n     *     redirectTo: 'user/:name'\n     *   }, {\n     *     path: 'user/:name',\n     *     component: User\n     *   }]\n     * }]\n     * ```\n     *\n     * The redirect path can be relative, as shown in this example, or absolute.\n     * If we change the `redirectTo` value in the example to the absolute URL segment '/user/:name',\n     * the result URL is also absolute, '/user/jim'.\n     * ### Empty Path\n     *\n     * Empty-path route configurations can be used to instantiate components that do not 'consume'\n     * any URL segments.\n     *\n     * In the following configuration, when navigating to\n     * `/team/11`, the router instantiates the 'AllUsers' component.\n     *\n     * ```\n     * [{\n     *   path: 'team/:id',\n     *   component: Team,\n     *   children: [{\n     *     path: '',\n     *     component: AllUsers\n     *   }, {\n     *     path: 'user/:name',\n     *     component: User\n     *   }]\n     * }]\n     * ```\n     *\n     * Empty-path routes can have children. In the following example, when navigating\n     * to `/team/11/user/jim`, the router instantiates the wrapper component with\n     * the user component in it.\n     *\n     * Note that an empty path route inherits its parent's parameters and data.\n     *\n     * ```\n     * [{\n     *   path: 'team/:id',\n     *   component: Team,\n     *   children: [{\n     *     path: '',\n     *     component: WrapperCmp,\n     *     children: [{\n     *       path: 'user/:name',\n     *       component: User\n     *     }]\n     *   }]\n     * }]\n     * ```\n     *\n     * ### Matching Strategy\n     *\n     * The default path-match strategy is 'prefix', which means that the router\n     * checks URL elements from the left to see if the URL matches a specified path.\n     * For example, '/team/11/user' matches 'team/:id'.\n     *\n     * ```\n     * [{\n     *   path: '',\n     *   pathMatch: 'prefix', //default\n     *   redirectTo: 'main'\n     * }, {\n     *   path: 'main',\n     *   component: Main\n     * }]\n     * ```\n     *\n     * You can specify the path-match strategy 'full' to make sure that the path\n     * covers the whole unconsumed URL. It is important to do this when redirecting\n     * empty-path routes. Otherwise, because an empty path is a prefix of any URL,\n     * the router would apply the redirect even when navigating to the redirect destination,\n     * creating an endless loop.\n     *\n     * In the following example, supplying the 'full' `pathMatch` strategy ensures\n     * that the router applies the redirect if and only if navigating to '/'.\n     *\n     * ```\n     * [{\n     *   path: '',\n     *   pathMatch: 'full',\n     *   redirectTo: 'main'\n     * }, {\n     *   path: 'main',\n     *   component: Main\n     * }]\n     * ```\n     *\n     * ### Componentless Routes\n     *\n     * You can share parameters between sibling components.\n     * For example, suppose that two sibling components should go next to each other,\n     * and both of them require an ID parameter. You can accomplish this using a route\n     * that does not specify a component at the top level.\n     *\n     * In the following example, 'MainChild' and 'AuxChild' are siblings.\n     * When navigating to 'parent/10/(a//aux:b)', the route instantiates\n     * the main child and aux child components next to each other.\n     * For this to work, the application component must have the primary and aux outlets defined.\n     *\n     * ```\n     * [{\n     *    path: 'parent/:id',\n     *    children: [\n     *      { path: 'a', component: MainChild },\n     *      { path: 'b', component: AuxChild, outlet: 'aux' }\n     *    ]\n     * }]\n     * ```\n     *\n     * The router merges the parameters, data, and resolve of the componentless\n     * parent into the parameters, data, and resolve of the children.\n     *\n     * This is especially useful when child components are defined\n     * with an empty path string, as in the following example.\n     * With this configuration, navigating to '/parent/10' creates\n     * the main child and aux components.\n     *\n     * ```\n     * [{\n     *    path: 'parent/:id',\n     *    children: [\n     *      { path: '', component: MainChild },\n     *      { path: '', component: AuxChild, outlet: 'aux' }\n     *    ]\n     * }]\n     * ```\n     *\n     * ### Lazy Loading\n     *\n     * Lazy loading speeds up application load time by splitting the application\n     * into multiple bundles and loading them on demand.\n     * To use lazy loading, provide the `loadChildren` property  instead of the `children` property.\n     *\n     * Given the following example route, the router will lazy load\n     * the associated module on demand using the browser native import system.\n     *\n     * ```\n     * [{\n     *   path: 'lazy',\n     *   loadChildren: () => import('./lazy-route/lazy.module').then(mod => mod.LazyModule),\n     * }];\n     * ```\n     *\n     * \\@publicApi\n     * @record\n     */\n\n\n    function Route() {}\n\n    if (false) {}\n\n    var LoadedRouterConfig =\n    /**\n     * @param {?} routes\n     * @param {?} module\n     */\n    function LoadedRouterConfig(routes, module) {\n      _classCallCheck(this, LoadedRouterConfig);\n\n      this.routes = routes;\n      this.module = module;\n    };\n\n    if (false) {}\n    /**\n     * @param {?} config\n     * @param {?=} parentPath\n     * @return {?}\n     */\n\n\n    function validateConfig(config) {\n      var parentPath = arguments.length > 1 && arguments[1] !== undefined ?
