Blog post "Angular v16 is now available".

Breaking Changes

• Angular Compatibility Compiler (ngcc) has been removed and as a result Angular View Engine libraries will no longer work
• Deprecated EventManager method addGlobalEventListener has been removed as it is not used by Ivy.

bazel

• Several changes to the Angular Package Format (APF)
  • Removal of FESM2015
  • Replacing ES2020 with ES2022
  • Replacing FESM2020 with FESM2022

  • Replacing ES2020 with ES2022
  • Replacing FESM2020 with FESM2022

common

• MockPlatformLocation is now provided by default in tests. Existing tests may have behaviors which rely on BrowserPlatformLocation instead. For example, direct access to the window.history in either the test or the component rather than going through the Angular APIs (Location.getState()). The quickest fix is to update the providers in the test suite to override the provider again TestBed.configureTestingModule({providers: [{provide: PlatformLocation, useClass: BrowserPlatformLocation}]}). The ideal fix would be to update the code to instead be compatible with MockPlatformLocation instead.
• If the 'ngTemplateOutletContext' is different from the context, it will result in a compile-time error.

Before the change, the following template was compiling:

interface MyContext {
  $implicit: string;
}

@Component({
  standalone: true,
  imports: [NgTemplateOutlet],
  selector: 'person',
  template: `
    <ng-container
      *ngTemplateOutlet="
        myTemplateRef;
        context: { $implicit: 'test', xxx: 'xxx' }
      "></ng-container>
  `,
})
export class PersonComponent {
  myTemplateRef!: TemplateRef<MyContext>;
}

However, it does not compile now because the 'xxx' property does not exist in 'MyContext', resulting in the error: 'Type '{ $implicit: string; xxx: string; }' is not assignable to type 'MyContext'.'

The solution is either:

• add the 'xxx' property to 'MyContext' with the correct type or
• add '$any(...)' inside the template to make the error disappear. However, adding '$any(...)' does not correct the error but only preserves the previous behavior of the code.
• Deprecated XhrFactory export from @angular/common/http has been removed. Use XhrFactory from @angular/common instead.

compiler

• • TypeScript 4.8 is no longer supported.

core

• QueryList.filter now supports type guard functions, which will result in type narrowing. Previously if you used type guard functions, it resulted in no changes to the return type. Now the type would be narrowed, which might require updates to the application code that relied on the old behavior.

• zone.js versions 0.11.x and 0.12.x are not longer supported.

• • entryComponents has been deleted from the @NgModule and @Component public APIs. Any usages can be removed since they weren't doing anyting.
  • ANALYZE_FOR_ENTRY_COMPONENTS injection token has been deleted. Any references can be removed.

• ComponentRef.setInput will only set the input on the component if it is different from the previous value (based on Object.is equality). If code relies on the input always being set, it should be updated to copy objects or wrap primitives in order to ensure the input value differs from the previous call to setInput.

• RendererType2.styles no longer accepts a nested arrays.

• The APP_ID token value is no longer randomly generated. If you are bootstrapping multiple application on the same page you will need to set to provide the APP_ID yourself.

  bootstrapApplication(ComponentA, {
    providers: [
     { provide: APP_ID, useValue: 'app-a' },
     // ... other providers ...
    ]
  });
  

• The ReflectiveInjector and related symbols were removed. Please update the code to avoid references to the ReflectiveInjector symbol. Use Injector.create as a replacement to create an injector instead.

• Node.js v14 support has been removed

  Node.js v14 is planned to be End-of-Life on 2023-04-30. Angular will stop supporting Node.js v14 in Angular v16. Angular v16 will continue to officially support Node.js versions v16 and v18.

platform-browser

• The deprecated BrowserTransferStateModule was removed, since it's no longer needed. The TransferState class can be injected without providing the module. The BrowserTransferStateModule was empty starting from v14 and you can just remove the reference to that module from your applications.

platform-server

• Users that are using SSR with JIT mode will now need to add import to @angular/compiler before bootstrapping the application.

  NOTE: this does not effect users using the Angular CLI.

• renderApplication method no longer accepts a root component as first argument. Instead, provide a bootstrapping function that returns a Promise<ApplicationRef>.

  Before

  const output: string = await renderApplication(RootComponent, options);
  

  Now

  const bootstrap = () => bootstrapApplication(RootComponent, appConfig);
  const output: string = await renderApplication(bootstrap, options);
  

• renderModuleFactory has been removed. Use renderModule instead.

router

• The Scroll event's routerEvent property may also be a NavigationSkipped event. Previously, it was only a NavigationEnd event.
• ComponentFactoryResolver has been removed from Router APIs. Component factories are not required to create an instance of a component dynamically. Passing a factory resolver via resolver argument is no longer needed and code can instead use ViewContainerRef.createComponent without the factory resolver.
• The RouterEvent type is no longer present in the Event union type representing all router event types. If you have code using something like filter((e: Event): e is RouterEvent => e instanceof RouterEvent), you'll need to update it to filter((e: Event|RouterEvent): e is RouterEvent => e instanceof RouterEvent).
• Tests which mock ActivatedRoute instances may need to be adjusted because Router.createUrlTree now does the right thing in more scenarios. This means that tests with invalid/incomplete ActivatedRoute mocks may behave differently than before. Additionally, tests may now navigate to a real URL where before they would navigate to the root. Ensure that tests provide expected routes to match. There is rarely production impact, but it has been found that relative navigations when using an ActivatedRoute that does not appear in the current router state were effectively ignored in the past. By creating the correct URLs, this sometimes resulted in different navigation behavior in the application. Most often, this happens when attempting to create a navigation that only updates query params using an empty command array, for example router.navigate([], {relativeTo: route, queryParams: newQueryParams}). In this case, the relativeTo property should be removed.

Deprecations

core

• makeStateKey, StateKey and TransferState exports have been moved from @angular/platform-browser to @angular/core. Please update the imports.

- import {makeStateKey, StateKey, TransferState} from '@angular/platform-browser';
+ import {makeStateKey, StateKey, TransferState} from '@angular/core';

• EnvironmentInjector.runInContext is now deprecated, with runInInjectionContext functioning as a direct replacement:

  // Previous method version (deprecated):
  envInjector.runInContext(fn);
  // New standalone function:
  runInInjectionContext(envInjector, fn);
  

• The @Directive/@Component moduleId property is now deprecated. It did not have any effect for multiple major versions and will be removed in v17.

platform-browser

• BrowserModule.withServerTransition has been deprecated. APP_ID should be used instead to set the application ID. NB: Unless, you render multiple Angular applications on the same page, setting an application ID is not necessary.

  Before:

  imports: [
    BrowserModule.withServerTransition({ appId: 'serverApp' }),
    ...
  ]
  

  After:

  imports: [
    BrowserModule,
    { provide: APP_ID, useValue: 'serverApp' },
    ...
  ],
  

• ApplicationConfig has moved, please import ApplicationConfig from @angular/core instead.

platform-server

• PlatformConfig.baseUrl and PlatformConfig.useAbsoluteUrl platform-server config options are deprecated as these were not used.

Deprecations

router

• CanLoad guards in the Router are deprecated. Use CanMatch instead.

• router writable properties

  The following strategies are meant to be configured by registering the application strategy in DI via the providers in the root NgModule or bootstrapApplication:

  • routeReuseStrategy
  • titleStrategy
  • urlHandlingStrategy

  The following options are meant to be configured using the options available in RouterModule.forRoot or provideRouter.

  • onSameUrlNavigation
  • paramsInheritanceStrategy
  • urlUpdateStrategy
  • canceledNavigationResolution

  The following options are available in RouterModule.forRoot but not available in provideRouter:

  • malformedUriErrorHandler - This was found to not be used anywhere internally.
  • errorHandler - Developers can instead subscribe to Router.events and filter for NavigationError.

<!-- CHANGELOG SPLIT MARKER -->

<a name="12.2.17"></a>

Blog post "Angular v15 is now available".

Breaking Changes

compiler

• Keyframes names are now prefixed with the component's "scope name". For example, the following keyframes rule in a component definition, whose "scope name" is host-my-cmp:

  @keyframes foo { ... }

  will become:

  @keyframes host-my-cmp_foo { ... }

  Any TypeScript/JavaScript code which relied on the names of keyframes rules will no longer match.

  The recommended solutions in this case are to either:

  • change the component's view encapsulation to the None or ShadowDom
  • define keyframes rules in global stylesheets (e.g styles.css)
  • define keyframes rules programmatically in code.

compiler-cli

• Invalid constructors for DI may now report compilation errors

  When a class inherits its constructor from a base class, the compiler may now report an error when that constructor cannot be used for DI purposes. This may either be because the base class is missing an Angular decorator such as @Injectable() or @Directive(), or because the constructor contains parameters which do not have an associated token (such as primitive types like string). These situations used to behave unexpectedly at runtime, where the class may be constructed without any of its constructor parameters, so this is now reported as an error during compilation.

  Any new errors that may be reported because of this change can be resolved either by decorating the base class from which the constructor is inherited, or by adding an explicit constructor to the class for which the error is reported.

• Angular compiler option enableIvy has been removed as Ivy is the only rendering engine.

core

• Angular no longer supports Node.js versions 14.[15-19].x and 16.[10-12].x. Current supported versions of Node.js are 14.20.x, 16.13.x and 18.10.x.
• TypeScript versions older than 4.8 are no longer supported.
• Existing iframe usages may have security-sensitive attributes applied as an attribute or property binding in a template or via host bindings in a directive. Such usages would require an update to ensure compliance with the new stricter rules around iframe bindings.
• Existing iframe usages may have src or srcdoc preceding other attributes. Such usages may need to be updated to ensure compliance with the new stricter rules around iframe bindings.

forms

• setDisabledState will always be called when a ControlValueAccessor is attached. You can opt-out with FormsModule.withConfig or ReactiveFormsModule.withConfig.

localize

• • canParse method has been removed from all translation parsers in @angular/localize/tools. analyze should be used instead.
  • the hint parameter in theparse methods is now mandatory.

router

• Previously, the RouterOutlet would immediately instantiate the component being activated during navigation. Now the component is not instantiated until the change detection runs. This could affect tests which do not trigger change detection after a router navigation. In rarer cases, this can affect production code that relies on the exact timing of component availability.
• The title property is now required on ActivatedRouteSnapshot
• relativeLinkResolution is no longer configurable in the Router. This option was used as a means to opt out of a bug fix.

Deprecations

common

• The DATE_PIPE_DEFAULT_TIMEZONE token is now deprecated in favor of the DATE_PIPE_DEFAULT_OPTIONS token, which accepts an object as a value and the timezone can be defined as a field (called timezone) on that object.

core

• • The ability to pass an NgModule to the providedIn option for @Injectable and InjectionToken is now deprecated.

  providedIn: NgModule was intended to be a tree-shakable alternative to NgModule providers. It does not have wide usage, and in most cases is used incorrectly, in circumstances where providedIn: 'root' should be preferred. If providers should truly be scoped to a specific NgModule, use NgModule.providers instead.

  • The ability to set providedIn: 'any' for an @Injectable or InjectionToken is now deprecated.

  providedIn: 'any' is an option with confusing semantics and is almost never used apart from a handful of esoteric cases internal to the framework.

• The bit field signature of Injector.get() has been deprecated, in favor of the new options object.

• The bit field signature of TestBed.inject() has been deprecated, in favor of the new options object.

router

• The RouterLinkWithHref directive is deprecated, use the RouterLink directive instead. The RouterLink contains the code from the RouterLinkWithHref to handle elements with href attributes.
