BREAKING CHANGE: Animations defined using an at-symbol prefix that are
not property bound are now invalid.
```html
<!-- this is now invalid -->
<div @flip="flipState"></div>
<!-- change that to -->
<div [@flip]="flipState"></div>
```
BREAKING CHANGE: Animations that are not bound using the at-symbol
prefix using `animate-` must now be preixed using `bind-animate-`.
```html
<!-- this is now invalid -->
<div animate-flip="flipState"></div>
<!-- is valid now -->
<div bind-animate-flip="flipState"></div>
```
Closes#10825
Remove TestComponentBuilder, addProviders, and withProviders. These
were deprecated in rc5 - see the changelog for update information.
Note - this does not actually remove the functions, but makes them
internal only. They will be removed from the codebase entirely
at a later time.
Closes#9751
BREAKING CHANGE:
These forms of providers are no longer accepted:
bind(MyClass).toFactory(...)
new Provider(MyClass, toFactory: ...)
We now only accept:
{provider: MyClass, toFactory: ...}
BREAKING CHANGE: previously deprecated SystemJsComponentResolver and SystemJsCmpFactoryResolver have been removed.
Please follow deprecation instructions to migrate your code.
BREAKING CHANGE: previously deprecated coreBootstrap and coreLoadAndBootstrap have been removed.
Please follow deprecation instructions to migrate your code.
BREAKING CHANGE: previously deprecated DirectiveMetadataType#properties and DirectiveMetadataType#events were removed; see deprecation notice for migration instructions.
This fixes an issue where `TestBed.overrideComponent(MyComp, {})`
would remove some properties including `providers` from the component.
This was due to the override not properly dealing with getter fields
on subclasses.
BREAKING CHANGE:
The deprecated `provideForms()` and `disableDeprecatedForms()` functions have been removed. Please import the `FormsModule` or the `ReactiveFormsModule` from @angular/forms instead.
BREAKING CHANGE:
The deprecated forms APIs in @angular/common have been removed. Please update to the new forms API in @angular/forms. See angular.io for more information.
Closes#9729
BREAKING CHANGE:
`Type` is now `Type<T>` which means that in most cases you have to
use `Type<any>` in place of `Type`.
We don't expect that any user applications use the `Type` type.
Remove test setup functions which were deprecated in rc5. See the
changelog for rc5 for how to update. In brief, instead of
`setBaseTestProviders`, use `TestBed.initTestEnvironment`.
We changed the bootstrap order:
1. create NgZone
2. bootstrap ng1 inside NgZone and upgrade ng1 components to ng2 components.
3. bootstrap ng2 with NgZone
Note: Previous footgun behavior was: bootstrap ng2 first to extract NgZone, so that ng1 bootstrap can happen in NgZone. This meant that if ng2 bootstrap eagerly compiled a component which contained ng1 components, then we did not have complete metadata.
BREAKING CHANGE: UpgradeAdapter.addProvider are now deprecated in favor of passing in an NgModule into the adapter's constructor
Before:
```
let upgradeAdapter = new UpgradeAdapter();
upgradeAdapter.addProviders([myProvidersArray);
```
After:
```
@NgModule({
providers: myProvidersArray
})
class MyModule {}
let upgradeAdapter = new UpgradeAdapter(MyModule);
```
Currently in the `linker/compiler.ts` file, the **same identifier** is used in **two declarations**:
```typescript
export type CompilerOptions = { … }
…
export const CompilerOptions = new OpaqueToken('compilerOptions');
```
This breaks the API doc generation. I’m surprised that this was not flagged by the tsc.
The duplicate declaration was introduced in 46b212706b.
Prior to this change `ngc` would place generated files which refer
to components in the node_modules into the node_module. This is an
issue. Now all of the files are forced into a single directory
as specified in `tsconfig.json` by the `genDir` option.
see: https://docs.google.com/document/d/1OgP1RIpZ-lWUc4113J3w13HTDcW-1-0o7TuGz0tGx0g
Because
- `Form` is **exported** -- see line 30/31 of
`modules/@angular/forms/src/forms.ts`: i.e., <br>`export {Form} from
'./directives/form_interface'`; and
- Methods of `Form`, which are public, have an
`AbstractFormGroupDirective` parameter;
e.g.,<br>`Form.getFormGroup(dir: AbstractFormGroupDirective):
FormGroup`.
Then it makes sense for `AbstractFormGroupDirective` to be
public/exported too. In any case, if it isn't exported then the **API
docs for `Form` don't get generated properly.**
BREAKING CHANGE:
- `ApplicationRef.run` is deprecated. Use `NgZone.run` directly
- `ApplicationRef.injector` is deprecated. Inject an `Injector` or
use `NgModuleRef.injector` instead
- `ApplicationRef.zone` is deprecated. Inject `NgZone` instead.
`ApplicationRef.bootstrap` is supposed to be run inside of `ngDoBootstrap` method
of the module that is bootstrapped, and that method already runs inside of the
zone.
This class allows any provider to know and wait for the initialization of the
application. This functionality previously was tied to `ApplicationRef`.
BREAKING CHANGE:
- `ApplicationRef.waitForAsyncInitializers` is deprecated. Use
`AppInitStatus.donePromise` / `AppInitStatus.done` instead.
If a `@NgModule` has a `bootstrap` property, `PlatformRef.bootstrapModule` /
`PlatformRef.bootstrapModuleFactory` will automatically bootstrap the components
listed in there.
If such a property does not exist, `PlatformRef.bootstrapModule` /
`PlatformRef.bootstrapModuleFactory` will try to call the method `ngDoBootstrap(appRef: ApplicationRef)` on the module class.
Otherwise an error is reported.
Using the `registerBootstrapListener` easily lead to race condition
and needed dependencies on `ApplicationRef`.
BREAKING CHANGE:
- `ApplicationRef.registerBootstrapListener` is deprecated. Provide a multi
provider for the new token `APP_BOOTSTRAP_LISTENER` instead.
Note about the addition of `beforeEach(fakeAsync(inject(…))))` in some tests:
`ApplicationRef` is now using `ngOnDestroy` and there is eager,
including all of its dependencies which contain `NgZone`.
The additional `fakeAsync` in `beforeEach` ensures that `NgZone`
uses the fake async zone as parent, and not the root zone.
BREAKING CHANGE (via deprecations):
- `ApplicationRef.dispose` is deprecated. Destroy the module that was
created during bootstrap instead by calling `NgModuleRef.destroy`.
- `AplicationRef.registerDisposeListener` is deprecated.
Use the `ngOnDestroy` lifecycle hook for providers or
`NgModuleRef.onDestroy` instead.
- `disposePlatform` is deprecated. Use `destroyPlatform` instead.
- `PlatformRef.dipose()` is deprecated. Use `PlatformRef.destroy()`
instead.
- `PlatformRef.registerDisposeListener` is deprecated. Use
`PlatformRef.onDestroy` instead.
- `PlaformRef.diposed` is deprecated. Use `PlatformRef.destroyed`
instead.
This is needed for the case if a `beforeEach` instantiates
`NgZone`and the `it` uses
`TestComponentBuilder.createFakeAsync`.
Otherwise the `NgZone` will use the root zone as parent,
and `TestComponentBuilder.createFakeAsync` will always return
undefined as `tick` does not forward promises created
under the zone of `NgZone`.
This makes `bootstrapModuleFactory` wait for promises
returned by `APP_INITIALIZER`s, also making `bootstrapModuleFactory` async.
I.e. now `bootstrapModule` and `bootstrapModuleFactory` behave in the
same way.
This ensures that all code from module instantiation, to creating
`ApplicationRef`s as well as calling `APP_INITIALIZERS` is run
in the Angular zone.
This also moves the invocation of the initializers from the `ApplicationRef`
constructor into the `bootstrapModuleFactory` call, allowing initializers
to get a hold of `ApplicationRef` (see #9101).
Fixes#9101Fixes#10363Fixes#10205
The methods on `ViewResolverMock` have been merged into `DirectiveResolver`.
BREAKING CHANGE:
- ES5 users can no longer use the `View(…)` function to provide `ViewMetadata`.
This mirrors the removal of the `@View` decorator a while ago.
Prior to this fix [ngClass] would remove all dynamic classes
when destroyed. It's essential that classes are persisted such
that remove-based animations will still be stylistically correct.
This patch fixes this issue.
Closes#10008Closes#10303
Previously, Angular would warn users when simply re-encoding text
outside of the ASCII range. While harmless, the log spam was annoying.
With this change, Angular specifically tracks whether anything was
stripped during sanitization, and only reports a warning if so.
Fixes#10206.
BREAKING CHANGES:
- `browserPlatform`/`browserDynamicPlatform`/... have been deprecated and renamed into `platformBrowser`/`platformBrowserDynamic`/....
- `bootstrapModule` and `bootstrapModuleFactory` have been moved to be members of `PlaformRef`.
E.g. `platformBrowserDynamic().bootstrapModule(MyModule)`.
This allows Angular to error on unknown properties,
allowing applications that don’t use custom elements
to get better error reporting.
Part of #10043
BREAKING CHANGE:
- By default, Angular will error during parsing
on unknown properties,
even if they are on elements with a `-` in their name
(aka custom elements). If you application is using
custom elements, fill the new parameter `@NgModule.schemas`
with the value `[CUSTOM_ELEMENTS_SCHEMA]`.
E.g. for bootstrap:
```
bootstrap(MyComponent, {schemas: [CUSTOM_ELEMENTS_SCHEMA]});
```
Part of #10043
BREAKING CHANGE:
- `@Component.precompile` was renamed to `@Component.entryComponents`
(old property still works but is deprecated)
- `ANALYZE_FOR_PRECOMPILE` was renamed to `ANALYZE_FOR_ENTRY_COMPONENTS` (no deprecations)
This contains major changes to the compiler, bootstrap of the platforms
and test environment initialization.
Main part of #10043Closes#10164
BREAKING CHANGE:
- Semantics and name of `@AppModule` (now `@NgModule`) changed quite a bit.
This is actually not breaking as `@AppModules` were not part of rc.4.
We will have detailed docs on `@NgModule` separately.
- `coreLoadAndBootstrap` and `coreBootstrap` can't be used any more (without migration support).
Use `bootstrapModule` / `bootstrapModuleFactory` instead.
- All Components listed in routes have to be part of the `declarations` of an NgModule.
Either directly on the bootstrap module / lazy loaded module, or in an NgModule imported by them.
Some test cases incorrectly rely on the side effect of other test cases
importing `NgMatchers`. This commit fixes this by making `expect` in
`core/testing_internal` properly typed.
Resource URLs are strictly "more" trustworthy than plain URLs, so trusting them maintains the same level of security while avoiding to break people when we downgrade a resource URL context to a plain URL context.
BREAKING CHANGE
Previously both imperative (router.navigate) and declarative (routerLink) navigations
would preserve the current query params and fragment. This behavior turned out to
be confusing. This commit changes it.
Now, neither is preserved by default. To preserve them, you need to do the following:
router.naviage("newUrl", {preserveQueryParams: true, preserveFragment: true})
<a routerLink="newUrl" preserveQueryParams preserveFragment></a>
This removes the magic from the `inject` test helper that would inspect
the current zone and would only work with our `async` test helper.
Now, `inject` is always synchronous, and if you are using a module
that requires async precompilation, you're required to call
`doAsyncPrecompilation` in your tests.
This is part of the breaking changes introduced with the swap
to each test having an AppModule.
Closes#9975Closes#9593
BREAKING CHANGE:
`TestInjector` is now renamed to `TestBed`
Before:
```js
import {TestInjector, getTestInjector} from '@angular/core/testing';
```
After:
```js
import {TestBed, getTestBed} from '@angular/core/testing';
```
Due to daa9da4047,
tests using the setBaseTestProviders stopped working with ambient directives such as
`ngIf`. Add them back in to keep the shim working.
This remove a breaking change introduced with commit #e7a8e2757b06d572f614f53b648d2fd75df370d2 where json objects passed to requests were not converted into string.
BREAKING CHANGE:
The behavior in this commit is the same as before PR 7260 : the objects sent with the request are converted to a string, therefore there is no need for the user to take care of the serialization.
Fixes#10073
The testing_e2e util does not belong in platform-browser and was never
intended to be a public API. Move it out of that whole tree.
BREAKING CHANGE:
The following API was never intended to be public and is removed:
```js
import {verifyNoBrowserErrors} from '@angular/platform-browser/testing_e2e';
```
Consider using Protractor's console plugin: https://github.com/angular/protractor-console-plugin
BREAKING CHANGES:
"{" is used a a delimiter for ICU messages then it could not be used in text nodes.
"{" should be escaped as "{{ '{' }}"
Before:
<span>some { valid } text</span>
After:
<span>some { invalid } text<span> <!-- throw parse error -->
<span>some {{ '{' }} valid } text</span>
This change reverts the removal of setBaseTestProviders that was
introduced in 8d746e3f67.
Instead, setBaseTestProviders and the providers provided from
`@angular/platform-browser-dynamic/testing` and `@angular/server/testing`
will still work for the next release, but are deprecated.
See 8d746e3f67 for how to upgrade.
BREAKING CHANGE (deprecations)
- Instead of `coreBootstrap`, create an `@AppModule` and use `bootstrapModule`.
- Instead of `coreLoadAndBootstarp`, create an `@AppModule` and use `bootstrapModuleFactory`.
- Instead of `bootstrapWorkerApp`, create an `@AppModule` that includes the `WorkerAppModule` and use `bootstrapModule` with the `workerAppPlatform()`.
- Instead of `bootstrapWorkerUi`, create an @AppModule that includes the `WorkerUiModule` and use `bootstrapModule` with the `workerUiPlatform()` instead.
- Instead of `serverBootstrap`, create an @AppModule and use `bootstrapModule` with the `serverDynamicPlatform()` instead.
- Instead of `PLATFORM_PIPES` and `PLATFORM_DIRECTIVES`, provide platform directives/pipes via an `@AppModule`.
- Instead of `ComponentResolver`:
- use `ComponentFactoryResolver` together with `@AppModule.precompile`/`@Component.precompile` or `ANALYZE_FOR_PRECOMPILE` provider for dynamic component creation.
- use `AppModuleFactoryLoader` for lazy loading.
- Instead of `SystemJsComponentResolver`, create an `@AppModule` and use `SystemJsAppModuleLoader`.
- Instead of `SystemJsCmpFactoryResolver`, create an `@AppModule` and use `SystemJsAppModuleFactoryLoader`
Closes#9726
- Introduces `CompilerFactory` which can be part of a `PlatformRef`.
- Introduces `WorkerAppModule`, `WorkerUiModule`, `ServerModule`
- Introduces `serverDynamicPlatform` for applications using runtime compilation
on the server.
- Changes browser bootstrap for runtime and offline compilation (see below for an example).
* introduces `bootstrapModule` and `bootstrapModuleFactory` in `@angular/core`
* introduces new `browserDynamicPlatform` in `@angular/platform-browser-dynamic
- Changes `initTestEnvironment` (which used to be `setBaseTestProviders`) to not take a compiler factory any more (see below for an example).
BREAKING CHANGE:
## Migration from `setBaseTestProviders` to `initTestEnvironment`:
- For the browser platform:
BEFORE:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS} from ‘@angular/platform-browser-dynamic/testing’;
setBaseTestProviders(TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS);
```
AFTER:
```
import {initTestEnvironment} from ‘@angular/core/testing’;
import {browserDynamicTestPlatform,
BrowserDynamicTestModule} from ‘@angular/platform-browser-dynamic/testing’;
initTestEnvironment(
BrowserDynamicTestModule,
browserDynamicTestPlatform());
```
- For the server platform:
BEFORE:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {TEST_SERVER_PLATFORM_PROVIDERS,
TEST_SERVER_APPLICATION_PROVIDERS} from ‘@angular/platform-server/testing/server’;
setBaseTestProviders(TEST_SERVER_PLATFORM_PROVIDERS,
TEST_SERVER_APPLICATION_PROVIDERS);
```
AFTER:
```
import {initTestEnvironment} from ‘@angular/core/testing’;
import {serverTestPlatform,
ServerTestModule} from ‘@angular/platform-browser-dynamic/testing’;
initTestEnvironment(
ServerTestModule,
serverTestPlatform());
```
## Bootstrap changes

```
Closes#9922
Part of #9726
We still support this via a hack, but should remove this soon.
This also fixes tests for module directives / pipes
as they used directives / pipes that were
already present in the underlying platform.
Animation triggers can now be set via template bindings `[]`
BREAKING CHANGE:
animation trigger expressions within the template that are assigned as
an element attribute (e.g. `@prop`) are deprecated. Please use the
Angular2 property binding syntax (e.g. `[@prop]`) when assigning
properties.
```ts
// this is now deprecated
<div @trigger="expression"></div>
// do this instead
<div [@trigger]="expression"></div>
```
Introduces the new `ANALYZE_FOR_PRECOMPILE` token. This token can be used to
create a virtual provider that will populate the `precompile` fields of
components and app modules based on its
`useValue`. All components that are referenced in the `useValue`
value (either directly or in a nested array or map) will be added
to the `precompile` property.
closes#9874
related to #9726
Closes#9732
BREAKING CHANGE:
We have removed the deprecated form directives from the built-in platform directive list, so apps are not required to package forms with their app. This also makes forms friendly to offline compilation.
Instead, we have exposed three modules:
OLD API:
- `DeprecatedFormsModule`
NEW API:
- `FormsModule`
- `ReactiveFormsModule`
If you provide one of these modules, the default forms directives and providers from that module will be available to you app-wide. Note: You can provide both the `FormsModule` and the `ReactiveFormsModule` together if you like, but they are fully-functional separately.
**Before:**
```ts
import {disableDeprecatedForms, provideForms} from @angular/forms;
bootstrap(App, [
disableDeprecatedForms(),
provideForms()
]);
```
**After:**
```ts
import {DeprecatedFormsModule} from @angular/common;
bootstrap(App, {modules: [DeprecatedFormsModule] });
```
-OR-
```ts
import {FormsModule} from @angular/forms;
bootstrap(App, {modules: [FormsModule] });
```
-OR-
```ts
import {ReactiveFormsModule} from @angular/forms;
bootstrap(App, {modules: [ReactiveFormsModule] });
```
You can also choose not to provide any forms module and run your app without forms.
Or you can choose not to provide any forms module *and* provide form directives at will. This will allow you to use the deprecatedForms API for some components and not others.
```
import {FORM_DIRECTIVES, FORM_PROVIDERS} from @angular/forms;
@Component({
selector: some-comp,
directives: [FORM_DIRECTIVES],
providers: [FORM_PROVIDERS]
})
class SomeComp
```
Every test now has an implicit module. It can be configured via `configureModule` (from @angular/core/testing)
to add providers, directives, pipes, ...
The compiler now has to be configured separately via `configureCompiler` (from @angular/core/testing)
to add providers or define whether to use jit.
BREAKING CHANGE:
- Application providers can no longer inject compiler internals (i.e. everything
from `@angular/compiler). Inject `Compiler` instead. This reflects the
changes to `bootstrap` for module support (3f55aa609f).
- Compiler providers can no longer be added via `addProviders` / `withProviders`.
Use the new method `configureCompiler` instead.
- Platform directives / pipes need to be provided via
`configureModule` and can no longer be provided via the
`PLATFORM_PIPES` / `PLATFORM_DIRECTIVES` tokens.
- `setBaseTestProviders()` was renamed into `initTestEnvironment` and
now takes a `PlatformRef` and a factory for a
`Compiler`.
- E.g. for the browser platform:
BEFORE:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS} from ‘@angular/platform-browser-dynamic/testing’;
setBaseTestProviders(TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS);
```
AFTER:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {browserTestCompiler, browserDynamicTestPlatform,
BrowserDynamicTestModule} from ‘@angular/platform-browser-dynamic/testing’;
initTestEnvironment(
browserTestCompiler,
browserDynamicTestPlatform(),
BrowserDynamicTestModule);
```
- E.g. for the server platform:
BEFORE:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {TEST_SERVER_PLATFORM_PROVIDERS,
TEST_SERVER_APPLICATION_PROVIDERS} from ‘@angular/platform-server/testing/server’;
setBaseTestProviders(TEST_SERVER_PLATFORM_PROVIDERS,
TEST_SERVER_APPLICATION_PROVIDERS);
```
AFTER:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {serverTestCompiler, serverTestPlatform,
ServerTestModule} from ‘@angular/platform-browser-dynamic/testing’;
initTestEnvironment(
serverTestCompiler,
serverTestPlatform(),
ServerTestModule);
```

RelectorHost threw an exception when metadata was requested for a
.d.ts file that didn't have a .metadata.json file. Changed it to
return undefined.
Fixes#9678
Added error correction so the parser always returns an AST
Added span information to the expression parser
Refactored the test to account for the difference in error reporting
Added tests for error corretion
Modified tests to validate the span information
This introduces the `BrowserModule` to be used for long form
bootstrap and offline compile bootstrap:
```
@AppModule({
modules: [BrowserModule],
precompile: [MainComponent],
providers: […], // additional providers
directives: […], // additional platform directives
pipes: […] // additional platform pipes
})
class MyModule {
constructor(appRef: ApplicationRef) {
appRef.bootstrap(MainComponent);
}
}
// offline compile
import {bootstrapModuleFactory} from ‘@angular/platform-browser’;
bootstrapModuleFactory(MyModuleNgFactory);
// runtime compile long form
import {bootstrapModule} from ‘@angular/platform-browser-dynamic’;
bootstrapModule(MyModule);
```
The short form, `bootstrap(...)`, can now creates a module on the fly,
given `directives`, `pipes, `providers`, `precompile` and `modules`
properties.
Related changes:
- make `SanitizationService`, `SecurityContext` public in `@angular/core` so that the offline compiler can resolve the token
- move `AnimationDriver` to `platform-browser` and make it
public so that the offline compiler can resolve the token
BREAKING CHANGES:
- short form bootstrap does no longer allow
to inject compiler internals (i.e. everything
from `@angular/compiler). Inject `Compiler` instead.
To provide custom providers for the compiler,
create a custom compiler via `browserCompiler({providers: [...]})`
and pass that into the `bootstrap` method.
