58 * @description
59 *
60 * Unwraps a value from an asynchronous primitive.
61 *
62 * The `async` pipe subscribes to an `Observable` or `Promise` and returns the latest value it has
63 * emitted. When a new value is emitted, the `async` pipe marks the component to be checked for
64 * changes. When the component gets destroyed, the `async` pipe unsubscribes automatically to avoid
65 * potential memory leaks. When the reference of the expression changes, the `async` pipe
66 * automatically unsubscribes from the old `Observable` or `Promise` and subscribes to the new one.
67 *
68 * @usageNotes
69 *
70 * ### Examples
71 *
72 * This example binds a `Promise` to the view. Clicking the `Resolve` button resolves the
73 * promise.
74 *
75 * {@example common/pipes/ts/async_pipe.ts region='AsyncPipePromise'}
76 *
77 * It's also possible to use `async` with Observables. The example below binds the `time` Observable
78 * to the view. The Observable continuously updates the view with the current time.

80 * {@example common/pipes/ts/async_pipe.ts region='AsyncPipeObservable'}

168 * @ngModule CommonModule
169 * @description
170 *
171 * Formats a date value according to locale rules.
172 *
173 * `DatePipe` is executed only when it detects a pure change to the input value.
174 * A pure change is either a change to a primitive input value
175 * (such as `String`, `Number`, `Boolean`, or `Symbol`),
176 * or a changed object reference (such as `Date`, `Array`, `Function`, or `Object`).
177 *
178 * Note that mutating a `Date` object does not cause the pipe to be rendered again.
179 * To ensure that the pipe is executed, you must create a new `Date` object.
180 *
181 * Only the `en-US` locale data comes with Angular. To localize dates
182 * in another language, you must import the corresponding locale data.
183 * See the [I18n guide](guide/i18n-common-format-data-locale) for more information.
184 *
185 * @see `formatDate()`
186 *
187 *
188 * @usageNotes
189 *
190 * The result of this pipe is not reevaluated when the input is mutated. To avoid the need to
191 * reformat the date on every change-detection cycle, treat the date as an immutable object
192 * and change the reference when the pipe needs to run again.
193 *
194 * ### Pre-defined format options
195 *
196 * | Option | Equivalent to | Examples (given in `en-US` locale) |
197 * |---------------|-------------------------------------|-------------------------------------------------|
198 * | `'short'` | `'M/d/yy, h:mm a'` | `6/15/15, 9:03 AM` |
199 * | `'medium'` | `'MMM d, y, h:mm:ss a'` | `Jun 15, 2015, 9:03:01 AM` |
200 * | `'long'` | `'MMMM d, y, h:mm:ss a z'` | `June 15, 2015 at 9:03:01 AM GMT+1` |
201 * | `'full'` | `'EEEE, MMMM d, y, h:mm:ss a zzzz'` | `Monday, June 15, 2015 at 9:03:01 AM GMT+01:00` |
202 * | `'shortDate'` | `'M/d/yy'` | `6/15/15` |
203 * | `'mediumDate'`| `'MMM d, y'` | `Jun 15, 2015` |
204 * | `'longDate'` | `'MMMM d, y'` | `June 15, 2015` |
205 * | `'fullDate'` | `'EEEE, MMMM d, y'` | `Monday, June 15, 2015` |
206 * | `'shortTime'` | `'h:mm a'` | `9:03 AM` |
207 * | `'mediumTime'`| `'h:mm:ss a'` | `9:03:01 AM` |
208 * | `'longTime'` | `'h:mm:ss a z'` | `9:03:01 AM GMT+1` |

211 * ### Custom format options
212 *
213 * You can construct a format string using symbols to specify the components
214 * of a date-time value, as described in the following table.
215 * Format details depend on the locale.
216 * Fields marked with (*) are only available in the extra data set for the given locale.

284 * ### Format examples
285 *
286 * These examples transform a date into various formats,
287 * assuming that `dateObj` is a JavaScript `Date` object for
288 * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,
289 * given in the local time for the `en-US` locale.
290 *
291 * ```
292 * {{ dateObj | date }} // output is 'Jun 15, 2015'
293 * {{ dateObj | date:'medium' }} // output is 'Jun 15, 2015, 9:43:11 PM'
294 * {{ dateObj | date:'shortTime' }} // output is '9:43 PM'
295 * {{ dateObj | date:'mm:ss' }} // output is '43:11'
296 * ```
297 *
298 * ### Usage example
299 *
300 * The following component uses a date pipe to display the current date in different formats.
301 *
302 * ```
303 * @Component({
304 * selector: 'date-pipe',
305 * template: `<div>
306 * <p>Today is {{today | date}}</p>
307 * <p>Or if you prefer, {{today | date:'fullDate'}}</p>
308 * <p>The time is {{today | date:'h:mm a z'}}</p>
309 * </div>`
310 * })
311 * // Get the current date and time as a date-time value.
312 * export class DatePipeComponent {
313 * today: number = Date.now();
314 * }
315 * ```

1044/**
1045 * @description
1046 *
1047 * A service that applications can use to interact with a browser's URL.
1048 *
1049 * Depending on the `LocationStrategy` used, `Location` persists
1050 * to the URL's path or the URL's hash segment.
1051 *
1052 * @usageNotes
1053 *
1054 * It's better to use the `Router.navigate()` service to trigger route changes. Use
1055 * `Location` only if you need to interact with or create normalized URLs outside of
1056 * routing.
1057 *
1058 * `Location` is responsible for normalizing the URL against the application's base href.
1059 * A normalized URL is absolute from the URL host, includes the application's base href, and has no
1060 * trailing slash:
1061 * - `/my/app/user/123` is normalized
1062 * - `my/app/user/123` **is not** normalized
1063 * - `/my/app/user/123/` **is not** normalized

1363 * the Component. Defaults to the injector of the current view container.
1364 *

1367 *
1368 * * `ngComponentOutletNgModuleFactory`: Optional module factory to allow loading another
1369 * module dynamically, then loading a component from that module.
1370 *
1371 * ### Syntax
1372 *
1373 * Simple
1374 * ```
1375 * <ng-container *ngComponentOutlet="componentTypeExpression"></ng-container>
1376 * ```
1377 *
1378 * Customized injector/content
1379 * ```
1380 * <ng-container *ngComponentOutlet="componentTypeExpression;
1381 * injector: injectorExpression;
1382 * content: contentNodesExpression;">
1383 * </ng-container>
1384 * ```
1385 *
1386 * Customized ngModuleFactory
1387 * ```

1417/**
1418 * A [structural directive](guide/structural-directives) that renders
1419 * a template for each item in a collection.
1420 * The directive is placed on an element, which becomes the parent
1421 * of the cloned templates.
1422 *
1423 * The `ngForOf` directive is generally used in the
1424 * [shorthand form](guide/structural-directives#asterisk) `*ngFor`.
1425 * In this form, the template to be rendered for each iteration is the content
1426 * of an anchor element containing the directive.
1427 *
1428 * The following example shows the shorthand syntax with some options,
1429 * contained in an `<li>` element.
1430 *
1431 * ```
1432 * <li *ngFor="let item of items; index as i; trackBy: trackByFn">...</li>
1433 * ```
1434 *
1435 * The shorthand form expands into a long form that uses the `ngForOf` selector
1436 * on an `<ng-template>` element.
1437 * The content of the `<ng-template>` element is the `<li>` element that held the
1438 * short-form directive.
1439 *
1440 * Here is the expanded version of the short-form example.
1441 *
1442 * ```
1443 * <ng-template ngFor let-item [ngForOf]="items" let-i="index" [ngForTrackBy]="trackByFn">
1444 * <li>...</li>
1445 * </ng-template>
1446 * ```
1447 *
1448 * Angular automatically expands the shorthand syntax as it compiles the template.
1449 * The context for each embedded view is logically merged to the current component
1450 * context according to its lexical position.
1451 *
1452 * When using the shorthand syntax, Angular allows only [one structural directive
1453 * on an element](guide/built-in-directives#one-per-element).
1454 * If you want to iterate conditionally, for example,
1455 * put the `*ngIf` on a container element that wraps the `*ngFor` element.
1456 * For futher discussion, see
1457 * [Structural Directives](guide/built-in-directives#one-per-element).
1458 *
1459 * @usageNotes
1460 *
1461 * ### Local variables
1462 *
1463 * `NgForOf` provides exported values that can be aliased to local variables.
1464 * For example:
1465 *
1466 * ```
1467 * <li *ngFor="let user of users; index as i; first as isFirst">
1468 * {{i}}/{{users.length}}. {{user}} <span *ngIf="isFirst">default</span>
1469 * </li>
1470 * ```
1471 *
1472 * The following exported values can be aliased to local variables:
1473 *
1474 * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).
1475 * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is
1476 * more complex then a property access, for example when using the async pipe (`userStreams |
1477 * async`).
1478 * - `index: number`: The index of the current item in the iterable.
1479 * - `count: number`: The length of the iterable.
1480 * - `first: boolean`: True when the item is the first item in the iterable.
1481 * - `last: boolean`: True when the item is the last item in the iterable.
1482 * - `even: boolean`: True when the item has an even index in the iterable.
1483 * - `odd: boolean`: True when the item has an odd index in the iterable.
1484 *
1485 * ### Change propagation
1486 *
1487 * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:
1488 *
1489 * * When an item is added, a new instance of the template is added to the DOM.
1490 * * When an item is removed, its template instance is removed from the DOM.
1491 * * When items are reordered, their respective templates are reordered in the DOM.
1492 *
1493 * Angular uses object identity to track insertions and deletions within the iterator and reproduce
1494 * those changes in the DOM. This has important implications for animations and any stateful
1495 * controls that are present, such as `<input>` elements that accept user input. Inserted rows can
1496 * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state
1497 * such as user input.
1498 * For more on animations, see [Transitions and Triggers](guide/transition-and-triggers).
1499 *
1500 * The identities of elements in the iterator can change while the data does not.
1501 * This can happen, for example, if the iterator is produced from an RPC to the server, and that
1502 * RPC is re-run. Even if the data hasn't changed, the second response produces objects with
1503 * different identities, and Angular must tear down the entire DOM and rebuild it (as if all old
1504 * elements were deleted and all new elements inserted).
1505 *
1506 * To avoid this expensive operation, you can customize the default tracking algorithm.
1507 * by supplying the `trackBy` option to `NgForOf`.
1508 * `trackBy` takes a function that has two arguments: `index` and `item`.
1509 * If `trackBy` is given, Angular tracks changes by the return value of the function.

1584/**
1585 * A structural directive that conditionally includes a template based on the value of
1586 * an expression coerced to Boolean.
1587 * When the expression evaluates to true, Angular renders the template
1588 * provided in a `then` clause, and when false or null,
1589 * Angular renders the template provided in an optional `else` clause. The default
1590 * template for the `else` clause is blank.
1591 *
1592 * A [shorthand form](guide/structural-directives#asterisk) of the directive,
1593 * `*ngIf="condition"`, is generally used, provided
1594 * as an attribute of the anchor element for the inserted template.
1595 * Angular expands this into a more explicit version, in which the anchor element
1596 * is contained in an `<ng-template>` element.
1597 *
1598 * Simple form with shorthand syntax:
1599 *
1600 * ```
1601 * <div *ngIf="condition">Content to render when condition is true.</div>
1602 * ```
1603 *
1604 * Simple form with expanded syntax:
1605 *
1606 * ```
1607 * <ng-template [ngIf]="condition"><div>Content to render when condition is
1608 * true.</div></ng-template>
1609 * ```
1610 *
1611 * Form with an "else" block:
1612 *
1613 * ```
1614 * <div *ngIf="condition; else elseBlock">Content to render when condition is true.</div>
1615 * <ng-template #elseBlock>Content to render when condition is false.</ng-template>
1616 * ```
1617 *
1618 * Shorthand form with "then" and "else" blocks:
1619 *
1620 * ```
1621 * <div *ngIf="condition; then thenBlock else elseBlock"></div>
1622 * <ng-template #thenBlock>Content to render when condition is true.</ng-template>
1623 * <ng-template #elseBlock>Content to render when condition is false.</ng-template>
1624 * ```
1625 *
1626 * Form with storing the value locally:
1627 *
1628 * ```
1629 * <div *ngIf="condition as value; else elseBlock">{{value}}</div>
1630 * <ng-template #elseBlock>Content to render when value is null.</ng-template>
1631 * ```
1632 *
1633 * @usageNotes
1634 *
1635 * The `*ngIf` directive is most commonly used to conditionally show an inline template,
1636 * as seen in the following example.
1637 * The default `else` template is blank.
1638 *
1639 * {@example common/ngIf/ts/module.ts region='NgIfSimple'}
1640 *
1641 * ### Showing an alternative template using `else`
1642 *
1643 * To display a template when `expression` evaluates to false, use an `else` template
1644 * binding as shown in the following example.
1645 * The `else` binding points to an `<ng-template>` element labeled `#elseBlock`.
1646 * The template can be defined anywhere in the component view, but is typically placed right after
1647 * `ngIf` for readability.
1648 *
1649 * {@example common/ngIf/ts/module.ts region='NgIfElse'}
1650 *
1651 * ### Using an external `then` template
1652 *
1653 * In the previous example, the then-clause template is specified inline, as the content of the
1654 * tag that contains the `ngIf` directive. You can also specify a template that is defined
1655 * externally, by referencing a labeled `<ng-template>` element. When you do this, you can
1656 * change which template to use at runtime, as shown in the following example.
1657 *
1658 * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}
1659 *
1660 * ### Storing a conditional result in a variable
1661 *
1662 * You might want to show a set of properties from the same object. If you are waiting
1663 * for asynchronous data, the object can be undefined.
1664 * In this case, you can use `ngIf` and store the result of the condition in a local
1665 * variable as shown in the following example.
1666 *
1667 * {@example common/ngIf/ts/module.ts region='NgIfAs'}
1668 *
1669 * This code uses only one `AsyncPipe`, so only one subscription is created.
1670 * The conditional statement stores the result of `userStream|async` in the local variable `user`.
1671 * You can then bind the local `user` repeatedly.
1672 *
1673 * The conditional displays the data only if `userStream` returns a value,
1674 * so you don't need to use the
1675 * safe-navigation-operator (`?.`)
1676 * to guard against null values when accessing properties.
1677 * You can display an alternative template while waiting for the data.
1678 *
1679 * ### Shorthand syntax
1680 *
1681 * The shorthand syntax `*ngIf` expands into two separate template specifications
1682 * for the "then" and "else" clauses. For example, consider the following shorthand statement,
1683 * that is meant to show a loading page while waiting for data to be loaded.
1684 *
1685 * ```
1686 * <div class="hero-list" *ngIf="heroes else loading">
1687 * ...
1688 * </div>
1689 *
1690 * <ng-template #loading>
1691 * <div>Loading...</div>
1692 * </ng-template>
1693 * ```
1694 *
1695 * You can see that the "else" clause references the `<ng-template>`
1696 * with the `#loading` label, and the template for the "then" clause
1697 * is provided as the content of the anchor element.
1698 *
1699 * However, when Angular expands the shorthand syntax, it creates
1700 * another `<ng-template>` tag, with `ngIf` and `ngIfElse` directives.
1701 * The anchor element containing the template for the "then" clause becomes
1702 * the content of this unlabeled `<ng-template>` tag.
1703 *
1704 * ```
1705 * <ng-template [ngIf]="heroes" [ngIfElse]="loading">
1706 * <div class="hero-list">
1707 * ...
1708 * </div>
1709 * </ng-template>
1710 *
1711 * <ng-template #loading>
1712 * <div>Loading...</div>
1713 * </ng-template>
1714 * ```
1715 *
1716 * The presence of the implicit template object has implications for the nesting of
1717 * structural directives. For more on this subject, see
1718 * [Structural Directives](https://angular.io/guide/built-in-directives#one-per-element).

2202 * For instance, if you provide an `APP_BASE_HREF` of `'/my/app/'` and call

2204 * `example.com/my/app/foo`. To ensure all relative URIs resolve correctly,
2205 * the `<base href>` and/or `APP_BASE_HREF` should end with a `/`.

2208 * `location.go('/foo')`, the browser's URL will become
