• The ComponentFactory and ComponentFactoryResolver classes are deprecated. Since Ivy, there is no need to resolve Component factories. Please use other APIs where you Component classes can be used directly (without resolving their factories).

• Since Ivy, the CompilerOptions.useJit and CompilerOptions.missingTranslation config options are unused, passing them has no effect.

13.0.0 (2021-11-03)

Blog post "Angular v13 is now available".

Breaking Changes

common

• The behavior of the SpyLocation used by the RouterTestingModule has changed to match the behavior of browsers. It no longer emits a 'popstate' event when Location.go is called. In addition, simulateHashChange now triggers both a hashchange and a popstate event. Tests which use location.go and expect the changes to be picked up by the Router should likely change to simulateHashChange instead. Each test is different in what it attempts to assert so there is no single change that works for all tests. Each test using the SpyLocation to simulate browser URL changes should be evaluated on a case-by-case basis.

core

• TypeScript versions older than 4.4.2 are no longer supported.

• NodeJS versions older than v12.20.0 are no longer supported due to the Angular packages using the NodeJS package exports feature with subpath patterns.

• The WrappedValue class can no longer be imported from @angular/core, which may result in compile errors or failures at runtime if outdated libraries are used that are still using WrappedValue. The usage of WrappedValue should be removed as no replacement is available.

forms

• A new type called FormControlStatus has been introduced, which is a union of all possible status strings for form controls. AbstractControl.status has been narrowed from string to FormControlStatus, and statusChanges has been narrowed from Observable<any> to Observable<FormControlStatus>. Most applications should consume the new types seamlessly. Any breakage caused by this change is likely due to one of the following two problems: (1) the app is comparing AbstractControl.status against a string which is not a valid status; or, (2) the app is using statusChanges events as if they were something other than strings.

router

• The default url serializer would previously drop everything after and including a question mark in query parameters. That is, for a navigation to /path?q=hello?&other=123, the query params would be parsed to just {q: 'hello'}. This is incorrect because the URI spec allows for question mark characers in query data. This change will now correctly parse the params for the above example to be {v: 'hello?', other: '123'}.

• Previously null and undefined inputs for routerLink were equivalent to empty string and there was no way to disable the link's navigation. In addition, the href is changed from a property HostBinding() to an attribute binding (HostBinding('attr.href')). The effect of this change is that DebugElement.properties['href'] will now return the href value returned by the native element which will be the full URL rather than the internal value of the RouterLink href property.

• When storing and retrieving a DetachedRouteHandle, the Router traverses the Route children in order to correctly allow storing a parent route when there are several possible child Route configs that can be stored. This allows a RouteReuseStrategy to store a parent Route and a child, while preserving the ability to change the child route while restoring the parent. Some implementations of RouteReuseStrategy will need to be updated to correctly store and retrieve the DetachedRouteHandle of descendants as well as the stored parent ActivatedRouteSnapshot. Previously, the Router would only store the parent, making it impossible to change descendant paths when a stored parent was retrieved. See #20114.

• The router will no longer replace the browser URL when a new navigation cancels an ongoing navigation. This often causes URL flicker and was only in place to support some AngularJS hybrid applications. Hybrid applications which rely on the navigationId being present on initial navigations that were handled by the Angular router should instead subscribe to NavigationCancel events and perform the location.replaceState themselves to add navigationId to the Router state. In addition, tests which assert urlChanges on the SpyLocation may need to be adjusted to account for the replaceState which is no longer triggered.

• It is no longer possible to use Route.loadChildren using a string value. The following supporting classes were removed from @angular/core:

• NgModuleFactoryLoader

• SystemJsNgModuleFactoryLoader

The @angular/router package no longer exports these symbols:

• SpyNgModuleFactoryLoader
• DeprecatedLoadChildren

The signature of the setupTestingRouter function from @angular/core/testing has been changed to drop its NgModuleFactoryLoader parameter, as an argument for that parameter can no longer be created.

service-worker

• The return type of SwUpdate#activateUpdate and SwUpdate#checkForUpdate changed to Promise<boolean>.

Although unlikely, it is possible that this change will cause TypeScript type-checking to fail in some cases. If necessary, update your types to account for the new return type.

Deprecations

core

• Angular no longer requires component factories to dynamically create components. The factory-based signature of the ViewContainerRef.createComponent function is deprecated in favor of a different signature that allows passing component classes instead.

• The getModuleFactory function is deprecated in favor of the getNgModuleById one. With Ivy, it's possible to work with NgModule classes directly, without retrieving corresponding factories, so the getNgModuleById should be used instead.

• Ivy made it possible to avoid the need to resolve Component and NgModule factories. Framework APIs allow to use Component and NgModule Types directly. As a result, the PlatformRef.bootstrapModuleFactory and a factory-based signature of the ApplicationRef.bootstrap method are now obsolete and are now deprecated. The PlatformRef.bootstrapModuleFactory calls can be replaced with PlatformRef.bootstrapModule ones. The ApplicationRef.bootstrap method allows to provide Component Type, so this can be used a replacement for the factory-based calls.

• In ViewEngine, JIT compilation required special providers (like Compiler, CompilerFactory, etc) to be injected in the app and corresponding methods to be invoked. With Ivy, JIT compilation takes place implicitly if the Component, NgModule, etc. have not already been AOT compiled. Those special providers were made available in Ivy for backwards-compatibility with ViewEngine to make the transition to Ivy smoother. Since ViewEngine is deprecated and will soon be removed, those symbols are now deprecated as well:

• ModuleWithComponentFactories

• Compiler

• CompilerFactory

• JitCompilerFactory

• NgModuleFactory

Important note: this deprecation doesn't affect JIT mode in Ivy (JIT remains available with Ivy).

• In Ivy, AOT summary files are unused in TestBed. Passing AOT summary files in TestBed has no effect, so the aotSummaries usage in TestBed is deprecated and will be removed in a future version of Angular.

platform-server

• The renderModuleFactory symbol in @angular/platform-server is no longer necessary as of Angular v13.

The renderModuleFactory calls can be replaced with renderModule.

service-worker

• The SwUpdate#activated observable is deprecated.

The SwUpdate#activated observable only emits values as a direct response to calling SwUpdate#activateUpdate() and was only useful for determining whether the call resulted in an update or not. Now, the return value of SwUpdate#activateUpdate() can be used to determine the outcome of the operation and therefore using SwUpdate#activated does not offer any benefit.

• The SwUpdate#availalbe observable is deprecated.

The new SwUpdate#versionUpdates observable provides the same information and more. Therefore, it is possible to rebuild the same behavior as SwUpdate#availalbe using the events emitted by SwUpdate#versionUpdates and filtering for VersionReadyEvent events. As a result, the SwUpdate#availalbe observable is now redundant.

• core: avoid storing LView in ngContext (#41358) (990067a), closes #41047
• core: optimize getDirectives (#41525) (f7e391a)

BREAKING CHANGES

• Minified UMD bundles are no longer included in the distributed NPM packages.
• animations: DOM elements are now correctly removed when the root view is removed. If you are using SSR and use the app's HTML for rendering, you will need to ensure that you save the HTML to a variable before destroying the app. It is also possible that tests could be accidentally relying on the old behavior by trying to find an element that was not removed in a previous test. If this is the case, the failing tests should be updated to ensure they have proper setup code which initializes elements they rely on.
• common: Methods of the PlatformLocation class, namely onPopState and onHashChange, used to return void. Now those methods return functions that can be called to remove event handlers.
• common: The methods of the HttpParams class now accept string | number | boolean instead of string for the value of a parameter. If you extended this class in your application, you'll have to update the signatures of your methods to reflect these changes.
• compiler-cli: Linked libraries no longer generate legacy i18n message ids. Any downstream application that provides translations for these messages, will need to migrate their message ids using the localize-migrate command line tool.
• core: Angular no longer maintains support for node v10
• core: Previously the ng.getDirectives function threw an error in case a given DOM node had no Angular context associated with it (for example if a function was called for a DOM element outside an Angular app). This behavior was inconsistent with other debugging utilities under ng namespace, which handled this situation without raising an exception. Now calling the ng.getDirectives function for such DOM nodes would result in an empty array returned from that function.
• core: Switching default of emitDistinctChangesOnlyDefaultValue which changes the default behavior and may cause some applications which rely on the incorrect behavior to fail.

emitDistinctChangesOnly flag has also been deprecated and will be removed in a future major release.

The previous implementation would fire changes QueryList.changes.subscribe whenever the QueryList was recomputed. This resulted in an artificially high number of change notifications, as it is possible that recomputing QueryList results in the same list. When the QueryList gets recomputed is an implementation detail, and it should not be the thing that determines how often change event should fire.

Unfortunately, fixing the behavior outright caused too many existing applications to fail. For this reason, Angular considers this fix a breaking fix and has introduced a flag in @ContentChildren and @ViewChildren, that controls the behavior.

export class QueryCompWithStrictChangeEmitParent {
  @ContentChildren('foo', {
    // This option is the new default with this change.
    emitDistinctChangesOnly: true,
  })
  foos!: QueryList<any>;
}

For backward compatibility before v12 emitDistinctChangesOnlyDefaultValue was set to false. This change the default to true.

• core: The type of the APP_INITIALIZER token has been changed to more accurately reflect the types of return values that are handled by Angular. Previously, each initializer callback was typed to return any, this is now Promise<unknown> | Observable<unknown> | void. In the unlikely event that your application uses the Injector.get or TestBed.inject API to inject the APP_INITIALIZER token, you may need to update the code to account for the stricter type.

Additionally, TypeScript may report the TS2742 error if the APP_INITIALIZER token is used in an expression of which its inferred type has to be emitted into a .d.ts file. To work around this, an explicit type annotation is needed, which would typically be Provider or Provider[].

• core: Minimum supported zone.js version is 0.11.4

• forms: The emitEvent option was added to the following FormArray and FormGroup methods:

• FormGroup.addControl

• FormGroup.removeControl

• FormGroup.setControl

• FormArray.push

• FormArray.insert

• FormArray.removeAt

• FormArray.setControl

• FormArray.clear

If your app has custom classes that extend FormArray or FormGroup classes and override the above-mentioned methods, you may need to update your implementation to take the new options into account and make sure that overrides are compatible from a types perspective.

• forms: Previously min and max attributes defined on the <input type="number"> were ignored by Forms module. Now presence of these attributes would trigger min/max validation logic (in case formControl, formControlName or ngModel directives are also present on a given input) and corresponding form control status would reflect that.
• platform-browser: XhrFactory has been moved from @angular/common/http to @angular/common.

Before

import {XhrFactory} from '@angular/common/http';

After

import {XhrFactory} from '@angular/common';

• router: Strict null checks will report on fragment potentially being null. Migration path: add null check.
• router: The type of the RouterLinkActive.routerLinkActiveOptions input was expanded to allow more fine-tuned control. Code that previously read this property may need to be updated to account for the new type.

• core: Previously the ng.getDirectives function threw an error in case a given DOM node had no Angular context associated with it (for example if a function was called for a DOM element outside an Angular app). This behavior was inconsistent with other debugging utilities under ng namespace, which handled this situation without raising an exception. Now calling the ng.getDirectives function for such DOM nodes would result in an empty array returned from that function.
• compiler-cli: Linked libraries no longer generate legacy i18n message ids. Any downstream application that provides translations for these messages, will need to migrate their message ids using the localize-migrate command line tool.

BREAKING CHANGES

• common:
  • 6acea54: The locale data API has been marked as returning readonly arrays, rather than mutable arrays, since these arrays are shared across calls to the API. If you were mutating them (e.g. calling sort(), push(), splice(), etc.) then your code will no longer compile. If you need to mutate the array, you should now make a copy (e.g. by calling slice()) and mutate the copy.
  • 26f2820: When passing a date-time formatted string to the DatePipe in a format that contains fractions of a millisecond, the milliseconds will now always be rounded down rather than to the nearest millisecond. Most applications will not be affected by this change. If this is not the desired behaviour then consider pre-processing the string to round the millisecond part before passing it to the DatePipe.
  • 4744c22: The slice pipe now returns null for the undefined input value, which is consistent with the behavior of most pipes. If you rely on undefined being the result in that case, you now need to check for it explicitly.
  • 4dfe0fa: The typing of the keyvalue pipe has been fixed to report that for input objects that have number keys, the result will contain the string representation of the keys. This was already the case and the types have simply been updated to reflect this. Please update the consumers of the pipe output if they were relying on the incorrect types. Note that this does not affect use cases where the input values are Maps, so if you need to preserve numbers, this is an effective way.
  • 7b2aac9: The signatures of the number pipes now explicitly state which types are accepted. This should only cause issues in corner cases, as any other values would result in runtime exceptions.
  • daf8b7f: The signature of the date pipe now explicitly states which types are accepted. This should only cause issues in corner cases, as any other values would result in runtime exceptions.
  • 5f815c0: The async pipe no longer claims to return undefined for an input that was typed as undefined. Note that the code actually returned null on undefined inputs. In the unlikely case you were relying on this, please fix the typing of the consumers of the pipe output.
  • c7d5555: The case conversion pipes no longer let falsy values through. They now map both null and undefined to null and raise an exception on invalid input (0, false, NaN) just like most "common pipes". If your code required falsy values to pass through, you need to handle them explicitly.
• compiler:
  • 736e064: TypeScript 3.9 is no longer supported, please upgrade to TypeScript 4.0.
• compiler-cli:
  • 0a16e60: Expressions within ICUs are now type-checked again, fixing a regression in Ivy. This may cause compilation failures if errors are found in expressions that appear within an ICU. Please correct these expressions to resolve the type-check errors.
• core:
  • fdea180: CollectionChangeRecord has been removed, use IterableChangeRecord instead.
  • c8f056b: If you call TestBed.overrideProvider after TestBed initialization, provider overrides are not applied. This behavior is consistent with other override methods (such as TestBed.overrideDirective, etc.) but they throw an error to indicate that, when the check was missing in the TestBed.overrideProvider function. Now calling TestBed.overrideProvider after TestBed initialization also triggers an error, thus there is a chance that some tests (where TestBed.overrideProvider is called after TestBed initialization) will start to fail and require updates to move TestBed.overrideProvider calls before TestBed initialization is completed.
  • 4ca1c73: In v10, IE 9, 10, and IE mobile support was deprecated. In v11, Angular framework removes IE 9, 10, and IE mobile support completely. Supporting outdated browsers like these increases bundle size, code complexity, and test load, and also requires time and effort that could be spent on improvements to the framework. For example, fixing issues can be more difficult, as a straightforward fix for modern browsers could break old ones that have quirks due to not receiving updates from vendors.
  • 4a1c12c: ViewEncapsulation.Native has been removed. Use ViewEncapsulation.ShadowDom instead. Existing usages will be updated automatically by ng update.
• forms:
  • d9fea85: Previously if FormControl, FormGroup and FormArray class instances had async validators defined at initialization time, the status change event was not emitted once async validators completed. After this change the status event is emitted into the statusChanges observable. If your code relies on the old behavior, you can filter/ignore this additional status change event.
  • 246de9a: Directives in the @angular/forms package used to have any[] as a type of validators and asyncValidators arguments in constructors. Now these arguments are properly typed, so if your code relies on directive constructor types it may require some updates to improve type safety.
  • f4f1bcc: Type of AbstractFormControl.parent now includes null. null is now included in the types of .parent. If you don't already have a check for this case, the TypeScript compiler might complain. A v11 migration exists which adds the non-null assertion operator where necessary. In an unlikely case your code was testing the parent against undefined with strict equality, you'll need to change this to === null instead, since the parent is now explicitly initialized with null instead of being left undefined.
• platform-server:
  • b4e8399: If you use useAbsoluteUrl to set up platform-server, you now need to also specify baseUrl. We are intentionally making this a breaking change in a minor release, because if useAbsoluteUrl is set to true then the behavior of the application could be unpredictable, resulting in issues that are hard to discover but could be affecting production environments.
• platform-webworker:
  • 93c3d8f: @angular/platform-webworker and @angular/platform-webworker-dynamic have been removed as they were deprecated in v8.
• router:
  • 3817e5f: This change corrects the argument order when calling RouteReuseStrategy#shouldReuseRoute. Previously, when evaluating child routes, they would be called with the future and current arguments would be swapped. If your RouteReuseStrategy relies specifically on only the future or current snapshot state, you may need to update the shouldReuseRoute implementation's use of "future" and "current" ActivatedRouteSnapshots.
  • e4f4d18: While the new parameter types allow a variable of type NavigationExtras to be passed in, they will not allow object literals, as they may only specify known properties. They will also not accept types that do not have properties in common with the ones in the Pick. To fix this error, only specify properties from the NavigationExtras which are actually used in the respective function calls or use a type assertion on the object or variable: as NavigationExtras.
  • 837889f: This commit changes the default value of relativeLinkResolution from 'legacy' to 'default'. If your application previously used the default by not specifying a value in the ExtraOptions and uses relative links when navigating from children of empty path routes, you will need to update your RouterModule to specifically specify 'legacy' for relativeLinkResolution. See https://angular.io/api/router/ExtraOptions#relativeLinkResolution for more details.
  • c4becca: The initialNavigation property for the options in RouterModule.forRoot no longer supports legacy_disabled, legacy_enabled, true, or false as valid values. legacy_enabled (the old default) is instead enabledNonBlocking.
  • c4becca: enabled is deprecated as a valid value for the RouterModule.forRoot initialNavigation option. enabledBlocking has been introduced to replace it.
  • 783a5bd: preserveQueryParams has been removed, use queryParamsHandling: "preserve" instead.
  • b0b4953: If you were accessing the RouterLink values of queryParams, fragment or queryParamsHandling you might need to relax the typing to also accept undefined and null.

Bug Fixes

• core: guard reading of global ngDevMode for undefined. (#36055) (02405f1)
• platform-server: Resolve absolute URL from baseUrl (#39334) (71fb99f)

BREAKING CHANGES

• platform-server: If you use useAbsoluteUrl to setup platform-server, you now need to also specify baseUrl. We are intentionally making this a breaking change in a minor release, because if useAbsoluteUrl is set to true then the behavior of the application could be unpredictable, resulting in issues that are hard to discover but could be affecting production environments.
