Add testability hook to downgraded component so that protractor can wait for asynchronous call to complete.
Add unregisterApplication() and unregisterAllApplications() to testability registry for cleaning up testability and unit test.
A multi RENDER_MODULE_HOOK provider can provide function that will be called with the current document just before the document is rendered to
string.
This hook can for example be used for the state transfer module to serialize any server state that needs to be transported to the client, just before the current platform state is rendered to string.

* The problem was with the `fireChildActivationStart` function. It was taking a `path` param, which was an

that weren't actually getting activated. This change fires the event only for those routes that are actually

Uses Domino - https://github.com/fgnass/domino and removes dependency on
Parse5.
The DOCUMENT and nativeElement were never typed earlier and were
different on the browser(DOM nodes) and the server(Parse5 nodes). With
this change, platform-server also exposes a DOCUMENT and nativeElement
that is closer to the client. If you were relying on nativeElement on
the server, you would have to change your code to use the DOM API now
instead of Parse5 AST API.
Removes the need to add services for each and every Document
manipulation like Title/Meta etc.
This does *not* provide a global variable 'document' or 'window' on the
server. You still have to inject DOCUMENT to get the document backing
the current platform server instance.
Today, constructing a new GET request with headers looks like:
const headers = new HttpHeaders({
'My-Header': 'header value',
});
http.get('/url', {headers}).subscribe(...);
This indirection is unnecessary. It'd be more ergonomic to write:
http.get('/url', {headers: {'My-Header': 'header value'}}).subscribe(...);
This commit allows that new syntax, both for HttpHeaders and HttpParams.
In the HttpParams case it also allows construction of HttpParams with a map.

PR Close#18781
BREAKING CHANGE: Because of multiple bugs and browser inconsistencies, we have dropped the intl api in favor of data exported from the Unicode Common Locale Data Repository (CLDR).
Unfortunately we had to change the i18n pipes (date, number, currency, percent) and there are some breaking changes.
1. I18n pipes
* Breaking change:
- By default Angular now only contains locale data for the language `en-US`, if you set the value of `LOCALE_ID` to another locale, you will have to import new locale data for this language because we don't use the intl API anymore.
* Features:
- you don't need to use the intl polyfill for Angular anymore.
- all i18n pipes now have an additional last parameter `locale` which allows you to use a specific locale instead of the one defined in the token `LOCALE_ID` (whose value is `en-US` by default).
- the new locale data extracted from CLDR are now available to developers as well and can be used through an API (which should be especially useful for library authors).
- you can still use the old pipes for now, but their names have been changed and they are no longer included in the `CommonModule`. To use them, you will have to import the `DeprecatedI18NPipesModule` after the `CommonModule` (the order is important):
```ts
import { NgModule } from '@angular/core';
import { CommonModule, DeprecatedI18NPipesModule } from '@angular/common';
@NgModule({
imports: [
CommonModule,
// import deprecated module after
DeprecatedI18NPipesModule
]
})
export class AppModule { }
```
Dont forget that you will still need to import the intl API polyfill if you want to use those deprecated pipes.
2. Date pipe
* Breaking changes:
- the predefined formats (`short`, `shortTime`, `shortDate`, `medium`, ...) now use the patterns given by CLDR (like it was in AngularJS) instead of the ones from the intl API. You might notice some changes, e.g. `shortDate` will be `8/15/17` instead of `8/15/2017` for `en-US`.
- the narrow version of eras is now `GGGGG` instead of `G`, the format `G` is now similar to `GG` and `GGG`.
- the narrow version of months is now `MMMMM` instead of `L`, the format `L` is now the short standalone version of months.
- the narrow version of the week day is now `EEEEE` instead of `E`, the format `E` is now similar to `EE` and `EEE`.
- the timezone `z` will now fallback to `O` and output `GMT+1` instead of the complete zone name (e.g. `Pacific Standard Time`), this is because the quantity of data required to have all the zone names in all of the existing locales is too big.
- the timezone `Z` will now output the ISO8601 basic format, e.g. `+0100`, you should now use `ZZZZ` to get `GMT+01:00`.
| Field type | Format | Example value | v4 | v5 |
|------------|---------------|-----------------------|----|---------------|
| Eras | Narrow | A for AD | G | GGGGG |
| Months | Narrow | S for September | L | MMMMM |
| Week day | Narrow | M for Monday | E | EEEEE |
| Timezone | Long location | Pacific Standard Time | z | Not available |
| Timezone | Long GMT | GMT+01:00 | Z | ZZZZ |
* Features
- new predefined formats `long`, `full`, `longTime`, `fullTime`.
- the format `yyy` is now supported, e.g. the year `52` will be `052` and the year `2017` will be `2017`.
- standalone months are now supported with the formats `L` to `LLLLL`.
- week of the year is now supported with the formats `w` and `ww`, e.g. weeks `5` and `05`.
- week of the month is now supported with the format `W`, e.g. week `3`.
- fractional seconds are now supported with the format `S` to `SSS`.
- day periods for AM/PM now supports additional formats `aa`, `aaa`, `aaaa` and `aaaaa`. The formats `a` to `aaa` are similar, while `aaaa` is the wide version if available (e.g. `ante meridiem` for `am`), or equivalent to `a` otherwise, and `aaaaa` is the narrow version (e.g. `a` for `am`).
- extra day periods are now supported with the formats `b` to `bbbbb` (and `B` to `BBBBB` for the standalone equivalents), e.g. `morning`, `noon`, `afternoon`, ....
- the short non-localized timezones are now available with the format `O` to `OOOO`. The formats `O` to `OOO` will output `GMT+1` while the format `OOOO` will be `GMT+01:00`.
- the ISO8601 basic time zones are now available with the formats `Z` to `ZZZZZ`. The formats `Z` to `ZZZ` will output `+0100`, while the format `ZZZZ` will be `GMT+01:00` and `ZZZZZ` will be `+01:00`.
* Bug fixes
- the date pipe will now work exactly the same across all browsers, which will fix a lot of bugs for safari and IE.
- eras can now be used on their own without the date, e.g. the format `GG` will be `AD` instead of `8 15, 2017 AD`.
3. Currency pipe
* Breaking change:
- the default value for `symbolDisplay` is now `symbol` instead of `code`. This means that by default you will see `$4.99` for `en-US` instead of `USD4.99` previously.
* Deprecation:
- the second parameter of the currency pipe (`symbolDisplay`) is no longer a boolean, it now takes the values `code`, `symbol` or `symbol-narrow`. A boolean value is still valid for now, but it is deprecated and it will print a warning message in the console.
* Features:
- you can now choose between `code`, `symbol` or `symbol-narrow` which gives you access to more options for some currencies (e.g. the canadian dollar with the code `CAD` has the symbol `CA$` and the symbol-narrow `$`).
4. Percent pipe
* Breaking change
- if you don't specify the number of digits to round to, the local format will be used (and it usually rounds numbers to 0 digits, instead of not rounding previously), e.g. `{{ 3.141592 | percent }}` will output `314%` for the locale `en-US` instead of `314.1592%` previously.

This commit introduces a new Input property called
`ngFormOptions` to the `NgForm` directive. You can use it
to set default `updateOn` values for all the form's child
controls. This default will be used unless the child has
already explicitly set its own `updateOn` value in
`ngModelOptions`.
Potential values: `change` | `blur` | `submit`
```html
<form [ngFormOptions]="{updateOn: blur}">
<input name="one" ngModel> <!-- will update on blur-->
</form>
```
For more context, see [#18577](https://github.com/angular/angular/pull/18577).
toString() from DefaultIterableDiffer is only used in tests and should not
be part of the production code. toString() methods from differs add
~ 0.3KB (min+gzip) to the production bundle size.
This commit introduces a new option to template-driven forms that
improves performance by delaying form control updates until the
"blur" or "submit" event. To use it, set the `updateOn` property
in `ngModelOptions`.
```html
<input ngModel [ngModelOptions]="{updateOn: blur}">
```
Like in AngularJS, setting `updateOn` to `blur` or `submit` will
delay the update of the value as well as the validation status.
Updating value and validity together keeps the system easy to reason
about, as the two will always be in sync. It's also worth noting
that the value/validation pipeline does still run when the form is
initialized (in order to support initial values).
Upcoming PRs will address:
* Support for setting group-level `updateOn` in template-driven forms
* Option for skipping initial validation run or more global error
display configuration
* Better support of reactive validation strategies
See more context in #18408, #18514, and the [design doc](https://docs.google.com/document/d/1dlJjRXYeuHRygryK0XoFrZNqW86jH4wobftCFyYa1PA/edit#heading=h.r6gn0i8f19wz).
BREAKING CHANGE
It is no longer possible to declare classes in this format.
```
Component({...}).
Class({
constructor: function() {...}
})
```
This format would only work with JIT and with ES5. This mode doesn’t
allow build tools like Webpack to process and optimize the code, which
results in prohibitively large bundles. We are removing this API
because we are trying to ensure that everyone is on the fast path by
default, and it is not possible to get on the fast path using the ES5
DSL. The replacement is to use TypeScript and `@Decorator` format.
```
@Component({...})
class {
constructor() {...}
}
```
The source map does not currently work with the transformer pipeline.
It will be re-enabled after TypeScript 2.4 is made the min version.
To revert to the former compiler, use the `disableTransformerPipeline` in
tsconfig.json:
```
{
"angularCompilerOptions": {
"disableTransformerPipeline": true
}
}
```
This commit adds support for setting default `updateOn` values
in `FormGroups` and `FormArrays`. If you set `updateOn` to
’blur’` at the group level, all child controls will default to `’blur’`,
unless the child has explicitly specified a different `updateOn` value.
```
const c = new FormGroup({
one: new FormControl()
}, {updateOn: blur});
```
It's worth noting that parent groups will always update their value and
validity immediately upon value/validity updates from children. In other
words, if a group is set to update on blur and its children are individually
set to update on change, the group will still update on change with its
children; its default value will simply not be used.
This change allows ReflectiveInjector to be tree shaken resulting
in not needed Reflect polyfil and smaller bundles.
Code savings for HelloWorld using Closure:
Reflective: bundle.js: 105,864(34,190 gzip)
Static: bundle.js: 154,889(33,555 gzip)
645( 2%)
BREAKING CHANGE:
`platformXXXX()` no longer accepts providers which depend on reflection.
Specifically the method signature when from `Provider[]` to
`StaticProvider[]`.
Example:
Before:
```
[
MyClass,
{provide: ClassA, useClass: SubClassA}
]
```
After:
```
[
{provide: MyClass, deps: [Dep1,...]},
{provide: ClassA, useClass: SubClassA, deps: [Dep1,...]}
]
```
NOTE: This only applies to platform creation and providers for the JIT
compiler. It does not apply to `@Compotent` or `@NgModule` provides
declarations.
Benchpress note: Previously Benchpress also supported reflective
provides, which now require static providers.
DEPRECATION:
- `ReflectiveInjector` is now deprecated as it will be remove. Use
`Injector.create` as a replacement.
closes#18496
FormControls, FormGroups, and FormArrays now optionally accept an options
object as their second argument. Validators and async validators can be
passed in as part of this options object (though they can still be passed
in as the second and third arg as before).
```ts
const c = new FormControl(, {
validators: [Validators.required],
asyncValidators: [myAsyncValidator]
});
```
This commit also adds support for passing arrays of validators and async
validators to FormGroups and FormArrays, which formerly only accepted
individual functions.
```ts
const g = new FormGroup({
one: new FormControl()
}, [myPasswordValidator, myOtherValidator]);
```
This change paves the way for adding more options to AbstractControls,
such as more fine-grained control of validation timing.
Angular can make many assumptions about its event handlers. As a result
the bookkeeping for native addEventListener is significantly cheaper
than Zone's addEventLister which can't make such assumptions.
This change bypasses the Zone's addEventListener if present and always
uses the native addEventHandler. As a result registering event listeners
is about 3 times faster.
PR Close#18107
HttpClient is an evolution of the existing Angular HTTP API, which exists
alongside of it in a separate package, @angular/common/http. This structure
ensures that existing codebases can slowly migrate to the new API.
The new API improves significantly on the ergonomics and features of the legacy
API. A partial list of new features includes:
* Typed, synchronous response body access, including support for JSON body types
* JSON is an assumed default and no longer needs to be explicitly parsed
* Interceptors allow middleware logic to be inserted into the pipeline
* Immutable request/response objects
* Progress events for both request upload and response download
* Post-request verification & flush based testing framework
Destructuring of the form:
function foo({a, b}: {a?, b?} = {})
breaks strictNullChecks, due to the TypeScript bug https://github.com/microsoft/typescript/issues/10078.
This change eliminates usage of destructuring in function argument lists in cases where it would leak
into the public API .d.ts.
With 4.2, we introduced the min and max validator directives. This was actually a breaking change because their selectors could include custom value accessors using the min/max properties for their own purposes.
For now, we are rolling back the change by removing the exports. At the least, we should wait to add them until a major version. In the meantime, we will have further discussion about what the best solution is going forward for all validator directives.
Closes#17491.

This puts the behavior introduced in 573b8611bc behind the new flag
`alwaysCompileGeneratedCode` to not break users that might have relied
on this behavior.
Previously the RequestOptions/ResponseOptions classes had constructors
with a destructured argument hash (represented by the
{Request,Response}OptionsArgs type). This type consists entirely of
optional members.
This produces a .d.ts file which includes the constructor declaration:
constructor({param, otherParam}?: OptionsArgs);
However, this declaration doesn't type-check properly. TypeScript
determines the actual type of the hash parameter to be OptionsArgs | undefined,
which it then concludes does not have a `param` or `otherParam` member.
This is a bug in TypeScript ( https://github.com/microsoft/typescript/issues/10078 ).
As a workaround, destructuring is moved inside the method, where it does not produce
broken artifacts in the .d.ts.
Fixes#16663.
Motivation: `yarn outdated`, for exmaple, shows the homepage URL on the command line. If copy-pasting or clicking on the URL, it's nice to see the repo's page instead of a 404.
Now converts shorthand imports for every TypeScript target. Tsickle is able to expand index shorthand imports for every TypeScript target and module possibility.
Expanding shorthand imports for CommonJS modules is also helpful when testing in the browser. Module loaders like SystemJS are not able to understand directory imports (or index shorthand imports)
`flush()` can now be used from within fakeAsync tests to simulate moving
time forward until all macrotask events have been cleared from the

Added an "origins" section to the flat module `.metadata.json` files
that records where the original symbols was declared. This allows
correctly calculating relative path references recorded in metadata.
This commit fixes a regression where `ngModel` no longer syncs
letter by letter on Android devices, and instead syncs at the
end of every word. This broke when we introduced buffering of
IME events so IMEs like Pinyin keyboards or Katakana keyboards
wouldn't display composition strings. Unfortunately, iOS devices
and Android devices have opposite event behavior. Whereas iOS
devices fire composition events for IME keyboards only, Android
fires composition events for Latin-language keyboards. For
this reason, languages like English don't work as expected on
Android if we always buffer. So to support both platforms,
composition string buffering will only be turned on by default
for non-Android devices.
However, we have also added a `COMPOSITION_BUFFER_MODE` token
to make this configurable by the application. In some cases, apps
might might still want to receive intermediate values. For example,
some inputs begin searching based on Latin letters before a
character selection is made.
As a provider, this is fairly flexible. If you want to turn
composition buffering off, simply provide the token at the top
level:
```ts
providers: [
{provide: COMPOSITION_BUFFER_MODE, useValue: false}
]
```
Or, if you want to change the mode based on locale or platform,
you can use a factory:
```ts
import {shouldUseBuffering} from 'my/lib';
....
providers: [
{provide: COMPOSITION_BUFFER_MODE, useFactory: shouldUseBuffering}
]
```

This is needed to support the corner cases:
- usage of a `ComponentFactory` that was created on the fly via `Compiler`
- overwriting of the `NgModuleRef` that is associated to a
`ComponentFactory` by the `ComponentFactoryResolver` from
which it was read.
Fixes#15241
The Router use the type `Params` for all of:
- position parameters,
- matrix parameters,
- query parameters.
`Params` is defined as follow `type Params = {[key: string]: any}`
Because parameters can either have single or multiple values, the type should
actually be `type Params = {[key: string]: string | string[]}`.
The client code often assumes that parameters have single values, as in the
following exemple:
```
class MyComponent {
sessionId: Observable<string>;
constructor(private route: ActivatedRoute) {}
ngOnInit() {
this.sessionId = this.route
.queryParams
.map(params => params['session_id'] || 'None');
}
}
```
The problem here is that `params['session_id']` could be `string` or `string[]`
but the error is not caught at build time because of the `any` type.
Fixing the type as describe above would break the build because `sessionId`
would becomes an `Observable<string | string[]>`.
However the client code knows if it expects a single or multiple values. By
using the new `ParamMap` interface the user code can decide when it needs a
single value (calling `ParamMap.get(): string`) or multiple values (calling
`ParamMap.getAll(): string[]`).
The above exemple should be rewritten as:
```
class MyComponent {
sessionId: Observable<string>;
constructor(private route: ActivatedRoute) {}
ngOnInit() {
this.sessionId = this.route
.queryParamMap
.map(paramMap => paramMap.get('session_id') || 'None');
}
}
```
Added APIs:
- `interface ParamMap`,
- `ActivatedRoute.paramMap: ParamMap`,
- `ActivatedRoute.queryParamMap: ParamMap`,
- `ActivatedRouteSnapshot.paramMap: ParamMap`,
- `ActivatedRouteSnapshot.queryParamMap: ParamMap`,
- `UrlSegment.parameterMap: ParamMap`
DEPRECATION:
- the arguments `inputs` / `outputs` / `ngContentSelectors` of `downgradeComponent`
are no longer used as Angular calculates these automatically now.
- Compiler.getNgContentSelectors is deprecated. Use
ComponentFactory.ngContentSelectors instead.
ErrorHandler can not throw errors because it will unsubscribe itself from
the error stream.
Zones captures errors and feed it into NgZone, which than has a Rx Observable
to feed it into ErrorHandler. If the ErroHandler throws, then Rx will teardown
the observable which in essence causes the ErrorHandler to be removed from the
error handling. This implies that the ErrorHandler can never throw errors.
Closes#14949Closes#15182Closes#14316
Update tsickle to version 0.21.6 which fixes a bug where input source maps which specified filenames differently than the names supplied to tsc didn't get composed with tsc's source maps. Also adds a test that the bug was fixed.
Observable subscriptions from previous validation runs should be canceled
before a new subscription is created for the next validation run.
Currently the subscription that sets the errors is canceled properly,
but the source observable created by the validator is not. While this
does not affect validation status or error setting, the source
observables will incorrectly continue through the pipeline until they
complete. This change ensures that the whole stream is canceled.
AsyncValidatorFn previously had an "any" return type, but now it more
explicitly requires a Promise or Observable return type. We don't
anticipate this causing problems given that any other return type
would have caused a runtime error already.
DEPRECATION:
- the arguments `inputs` / `outputs` / `ngContentSelectors` of `downgradeComponent`
are no longer used as Angular calculates these automatically now.
- Compiler.getNgContentSelectors is deprecated. Use
ComponentFactory.ngContentSelectors instead.
In order for tsickle's new support for input source maps to work, the tsickleCompilerHost must be used for the initial load of source files, since that's when the inline source maps are read and stripped.

BREAKING CHANGES
`ComponentFactory.create()` takes an extra optional `NgModuleRef` parameter.

DEPRECATIONS
The following methods were used internally and are no more required:

BREAKING CHANGE:
Perviously, any provider that had an ngOnDestroy lifecycle hook would be created eagerly.
Now, only classes that are annotated with @Component, @Directive, @Pipe, @NgModule are eager. Providers only become eager if they are either directly or transitively injected into one of the above.
This also makes all `useValue` providers eager, which
should have no observable impact other than code size.
EXPECTED IMPACT:
Making providers eager was an incorrect behavior and never documented.
Also, providers that are used by a directive / pipe / ngModule stay eager.
So the impact should be rather small.
Fixes#14552

instead of `RouterModule.forRoot(routes, {initialNavigation: false})`.
Deprecated options: 'legacy_enabled', `true` (same as 'legacy_enabled'),
'legacy_disabled', `false` (same as 'legacy_disabled').
The "Router Initial Navigation" design document covers this change.

After the introduction of the view engine, we can drop a lot of code that is not used any more.
This should reduce the size of the app bundles because a lot of this code was not being properly tree-shaken by today's tools even though it was dead code.
- Don’t use the animation renderer if a component
used style encapsulation but no animations.
- The `AnimationRenderer` should be cached in the same
lifecycle as its delegate.
- Trigger names need to be namespaced per component type.
When the `enableLegacyTemplate` is set to `false`, `<template>` tags and the
`template` attribute are no more used to define angular templates but are
treated as regular tag and attribute.
The default value is `true`.
In order to define a template, you have to use the `<ng-template>` tag.
This option applies to your application and all the libraries it uses. That is
you should make sure none of them rely on the legacy way to defined templates
when this option is turned off (`false`).
BREAKING CHANGE: Because all lifecycle hooks are now interfaces
the code that uses 'extends' keyword will no longer compile.
To migrate the code follow the example below:
Before:
```
@Component()
class SomeComponent extends OnInit {}
```
After:
```
@Component()
class SomeComponent implements OnInit {}
```
we don't expect anyone to be affected by this change.
Closes#10083
Use `RendererV2` instead of `Renderer` now. `Renderer` can still be injected
and delegates to `RendererV2`.
Use `RendererFactoryV2` instead of `RootRenderer`. `RootRenderer` cannot be used
anymore.
BREAKING CHANGE:
- `RootRenderer` cannot be used any more, use `RendererFactoryV2` instead.
Note: `Renderer` can still be injected/used, but is deprecated.
Currently styles are rendered to the root component element, which ensures they're cleaned up automatically
when the client application is bootstrapped. This is less than ideal as progressive rendering can cause HTML
to be rendered before the CSS is loaded, causing flicker.
This change returns to rendering <style> elements in the <head>, and introduces a mechanism for removing
them on client bootstrap. This relies on associating the server and client bootstrap. Another way to think
of this is that the client, when bootstrapping an app, needs to know whether to expect a server rendered
application exists on the page, and to identify the <style> elements that are part of that app in order
to remove them.
This is accomplished by providing a string TRANSITION_ID on both server and client. For most applications,
this will be achieved by writing a client app module that imports BrowserModule.withServerTransition({appId: <id>}).
The server app module will import this client app module and therefore inherit the provider for
TRANSITION_ID. renderModule[Factory] on the server will validate that a TRANSITION_ID has been provided.
TypeScript compiler will now build to ES2015 code and modules. Babili is used to minify ES2015
code, providing an initial optimization that we couldn't previously get just from Uglify. Uses
Babel to convert ES2015 to UMD/ES5 code, and Uglify to minimize the output.
