component or service\n * as a dependency.\n *\n * \n *\n * To subscribe, call `SwPush.requestSubscription()`, which asks the user for permission.\n * The call returns a `Promise` with a new\n *

or does not support the Push API or ServiceWorkers.\n * Check `SwPush.isEnabled` to confirm status.\n *\n * Invoke Push Notifications by pushing a message with the following payload.\n *\n * ```ts\n * {\n * \"notification\": {\n * \"actions\": NotificationAction[],\n * \"badge\": USVString,\n * \"body\": DOMString,\n * \"data\": any,\n * \"dir\": \"auto\"|\"ltr\"|\"rtl\",\n * \"icon\": USVString,\n

\"title\": DOMString,\n * \"vibrate\": number[]\n * }\n * }\n * ```\n *\n * Only `title` is required. See `Notification`\n * [instance\n * properties](https://developer.mozilla.org/en-US/docs/Web/API/Notification#Instance_properties).\n *\n * While the subscription is active, Service Worker listens for\n * [PushEvent](https://developer.mozilla.org/en-US/docs/Web/API/PushEvent)\n * occurrences and creates\n * [Notification](https://developer.mozilla.org/en-US/docs/Web/API/Notification)\n * instances in response.\n *\n * Unsubscribe using `SwPush.unsubscribe()`.\n *\n * An application can subscribe to `SwPush.notificationClicks` observable to be notified when a user\n * clicks on a notification.

[`state()`](api/animations/state)\n * and `transition()` entries to be evaluated when the expression\n * bound to the trigger changes.\n *\n * @param name An identifying string.\n * @param definitions An animation definition object, containing an array of\n * [`state()`](api/animations/state) and `transition()` declarations.\n *\n * @return An object that encapsulates the trigger data.\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 * \n *
...
\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 * @Component({\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 * @Component({\n * selector: 'my-component',\n * template: `\n *
\n *
\n *
\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 * @Component({\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 */\nfunction trigger(name, definitions) {\n return { type: 7 /* AnimationMetadataType.Trigger */, name, definitions, options: {} };\n}\n/**\n * Defines an animation step that combines styling information with timing information.\n *\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.

\n *\n * Be careful about entering end leaving elements as their transitions present a common\n * pitfall for developers.\n *\n * Note that when an element with a trigger enters the DOM its `:enter` transition always\n * gets executed, but its `:leave` transition will not be executed if the element is removed\n * alongside its parent (as it will be removed \"without warning\" before its transition has\n * a chance to be executed, the only way that such transition can occur is if the element\n * is exiting the DOM on its own).\n *\n *\n *
\n *\n * ### Animating to a Final State\n *\n * If the final step in a transition is a call to `animate()` that uses a timing value\n * with no `style` data, that step is automatically considered the final animation arc,\n * for the element to reach the final state, in such case Angular automatically adds or removes\n * CSS styles to ensure that the element is in the correct final state.\n *\n *\n * ### Usage Examples\n *\n * - Transition animations applied based on\n * the trigger's expression value\n *\n * ```HTML\n *
\n * ...\n *
\n * ```\n *\n * ```typescript\n * trigger(\"myAnimationTrigger\", [\n * ..., // states\n * transition(\"on => off, open => closed\", animate(500)),\n * transition(\"* <=> error\", query('.indicator', animateChild()))\n * ])\n * ```\n *\n * - Transition animations applied based on custom logic dependent\n * on the trigger's expression value and provided parameters\n *\n * ```HTML\n *
\n * ...\n *
\n * ```\n *\n * ```typescript\n * trigger(\"myAnimationTrigger\", [\n * ..., // states\n * transition(\n * (fromState, toState, _element, params) =>\n * ['firststep', 'laststep'].includes(fromState.toLowerCase())\n * && toState === params?.['target'],\n * animate('1s')\n * )\n * ])\n * ```\n *\n * @publicApi\n **/\nfunction transition(stateChangeExpr, steps, options = null) {\n return { type: 1 /* AnimationMetadataType.Transition */, expr: stateChangeExpr, animation: steps, options };\n}\n/**\n * Produces a reusable animation that can be invoked in another animation or sequence,\n * by calling the `useAnimation()` function.\n *\n * @param steps One or more animation objects, as returned by the `animate()`\n * or `sequence()` function, that form a transformation from one state to another.\n * A sequence is used by default when you pass an array.\n * @param options An options object that can contain a delay value for the start of the\n * animation, and additional developer-defined parameters.\n * Provided values for additional parameters are used as defaults,\n * and override values can be passed to the caller on invocation.\n * @returns An object that encapsulates the animation data.\n *\n * @usageNotes\n * The following example defines a reusable animation, providing some default parameter\n * values.\n *\n * ```typescript\n * var fadeAnimation = animation([\n * style({ opacity: '{{ start }}' }),\n * animate('{{ time }}',\n * style({ opacity: '{{ end }}'}))\n * ],\n * { params: { time: '1000ms', start: 0, end: 1 }});\n * ```\n *\n * The following invokes the defined animation with a call to `useAnimation()`,\n * passing in override parameter values.\n *\n * ```js\n * useAnimation(fadeAnimation, {\n * params: {\n * time: '2s',\n * start: 1,\n * end: 0\n * }\n * })\n * ```\n *\n * If any of the passed-in parameter values are missing from this call,\n * the default values are used.

For example:\n *\n * ```typescript\n * query(':self, .record:enter, .record:leave, @subTrigger', [...])\n * ```\n *\n * The `query()` function collects multiple elements and works internally by using\n * `element.querySelectorAll`. Use the `limit` field of an options object to limit\n * the total number of items to be collected. For example:\n *\n * ```js\n * query('div', [\n * animate(...),\n * animate(...)\n * ], { limit: 1 })\n * ```\n *\n * By default, throws an error when zero items are found. Set the\n * `optional` flag to ignore this error. For example:\n *\n * ```js\n * query('.some-element-that-may-not-be-there', [\n * animate(...),\n * animate(...)\n * ], { optional: true })\n * ```\n *\n * ### Entering and Leaving Elements\n *\n * Not all elements can be queried via the `:enter` and `:leave` tokens, the only ones\n * that can are those that Angular assumes can enter/leave based on their own logic\n * (if their insertion/removal is simply a consequence of that of their parent they\n * should be queried via a different token in their parent's `:enter`/`:leave` transitions).\n *\n * The only elements Angular assumes can enter/leave based on their own logic (thus the only\n * ones that can be queried via the `:enter` and `:leave` tokens) are:\n * - Those inserted dynamically (via `ViewContainerRef`)\n * - Those that have a structural directive (which, under the hood, are a subset of the above ones)\n *\n *
\n *\n * Note that elements will be successfully queried via `:enter`/`:leave` even if their\n * insertion/removal is not done manually via `ViewContainerRef`or caused by their structural\n * directive (e.g. they enter/exit alongside their parent).\n *\n *
\n *\n *
\n *\n * There is an exception to what previously mentioned, besides elements entering/leaving based on\n * their own logic, elements with an animation trigger can always be queried via `:leave` when\n * their parent is also leaving.\n *\n *
\n *\n * ### Usage Example\n *\n * The following example queries for inner elements and animates them\n * individually using `animate()`.\n *\n * ```typescript\n * @Component({\n * selector: 'inner',\n * template: `\n *

Overlap of animations\n * Given that a CSS property cannot be animated in more than one place at the same time, it's\n * important that this behavior is detected and validated.

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.

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 within 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 map. The `copyStyles` method in util.ts\n * handles propagating that backfill map to the styles object.\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 * [Validation]\n * The code in this file is not responsible for validation. That functionality happens with within\n * the `AnimationValidatorVisitor` code.\n */\nfunction buildAnimationTimelines(driver, rootElement, ast, enterClassName, leaveClassName, startingStyles = new Map(), finalStyles = new Map(), options, subInstructions, errors = []) {\n return new AnimationTimelineBuilderVisitor().buildKeyframes(driver, rootElement, ast, enterClassName, leaveClassName, startingStyles, finalStyles, options, subInstructions, errors);\n}\nclass AnimationTimelineBuilderVisitor {\n buildKeyframes(driver, rootElement, ast, enterClassName, leaveClassName, startingStyles, finalStyles, options, subInstructions, errors = []) {\n subInstructions = subInstructions || new ElementInstructionMap();\n const context = new AnimationTimelineContext(driver, rootElement, subInstructions, enterClassName, leaveClassName, errors, []);\n context.options = options;\n const delay = options.delay ?

  • \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`: 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 * - `count: number`: The length of 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 `` 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 */\nclass NgForOf {\n /**\n * The value of the iterable expression, which can be used as a\n * [template input variable](guide/structural-directives#shorthand).\n */\n set ngForOf(ngForOf) {\n this._ngForOf = ngForOf;\n this._ngForOfDirty = true;\n }\n /**\n * Specifies a custom `TrackByFunction` to compute the identity of items in an iterable.\n *\n * If a custom `TrackByFunction` is not provided, `NgForOf` will use the item's [object\n * identity](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is)\n * as the key.\n *\n * `NgForOf` uses the computed key to associate items in an iterable with DOM elements\n * it produces for these items.\n *\n * A custom `TrackByFunction` is useful to provide good user experience in cases when items in an\n * iterable rendered using `NgForOf` have a natural identifier (for example, custom ID or a\n * primary key), and this iterable could be updated with new object instances that still\n * represent the same underlying entity (for example, when data is re-fetched from the server,\n * and the iterable is recreated and re-rendered, but most of the data is still the same).\n *\n * @see {@link TrackByFunction}\n */\n set ngForTrackBy(fn) {\n if ((typeof ngDevMode === 'undefined' || ngDevMode) && fn != null && typeof fn !== 'function') {\n console.warn(`trackBy must be a function, but received ${JSON.stringify(fn)}. ` +\n `See https://angular.io/api/common/NgForOf#change-propagation for more information.`);\n }\n this._trackByFn = fn;\n }\n get ngForTrackBy() {\n return this._trackByFn;\n }\n constructor(_viewContainer, _template, _differs) {\n this._viewContainer = _viewContainer;\n this._template = _template;\n this._differs = _differs;\n this._ngForOf = null;\n this._ngForOfDirty = true;\n this._differ = null;\n }\n /**\n * A reference to the template that is stamped out for each item in the iterable.\n * @see [template reference variable](guide/template-reference-variables)\n */\n set ngForTemplate(value) {\n // TODO(TS2.1): make TemplateRef>> once we move to TS v2.1\n // The current type is too restrictive; a template that just uses index, for example,\n // should be acceptable.\n if (value) {\n this._template = value;\n }\n }\n /**\n * Applies the changes when needed.\n * @nodoc\n */\n ngDoCheck() {\n if (this._ngForOfDirty) {\n this._ngForOfDirty = false;\n // React on ngForOf changes only once all inputs have been initialized\n const value = this._ngForOf;\n if (!this._differ && value) {\n if (typeof ngDevMode === 'undefined' || ngDevMode) {\n try {\n // CAUTION: this logic is duplicated for production mode below, as the try-catch\n // is only present in development builds.\n this._differ = this._differs.find(value).create(this.ngForTrackBy);\n }\n catch {\n let errorMessage = `Cannot find a differ supporting object '${value}' of type '` +\n `${getTypeName(value)}'.

You can also specify a template that is defined\n * externally, by referencing a labeled `` 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 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 (`?.`)\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 *
    \n * ...\n *
    \n *\n * \n *
    Loading...
    \n *
    \n * ```\n *\n * You can see that the \"else\" clause references the ``\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 `` tag, with `ngIf` and `ngIfElse` directives.\n * The anchor element containing the template for the \"then\" clause becomes\n * the content of this unlabeled `` tag.\n *\n * ```\n * \n *
    \n * ...\n *
    \n *
    \n *\n * \n *
    Loading...

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 * {{ dateObj | date:\"MMM dd, yyyy 'at' hh:mm a\" }} // output is 'Jun 15, 2015 at 09:43 PM'\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: `
