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:
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>.
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

Breaking Changes
core
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.
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

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.

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:

core
Support for Node.js v12 has been removed as it will become EOL on 2022-04-30. Please use Node.js v14.15 or later.
TypeScript versions older than 4.6 are no longer supported.
Forms [email] input coercion
Forms [email] input value will be considered as true if it is defined with any value rather
than false and 'false'.
Since Ivy, TestBed doesn't use AOT summaries. The aotSummaries fields in TestBed APIs were present, but unused. The fields were deprecated in previous major version and in v14 those fields are removed. The aotSummaries fields were completely unused, so you can just drop them from the TestBed APIs usage.
forms
Forms classes accept a generic.
Forms model classes now accept a generic type parameter. Untyped versions of these classes are available to opt-out of the new, stricter behavior.
objects with a length key set to zero will no longer validate as empty.
This is technically a breaking change, since objects with a key length and value 0 will no longer validate as empty. This is a very minor change, and any reliance on this behavior is probably a bug anyway.
http
Queries including + will now actually query for + instead of space.
Most workarounds involving custom codecs will be unaffected.
Possible server-side workarounds will need to be undone.
JSONP will throw an error when headers are set on a reques
JSONP does not support headers being set on requests. Before when
a request was sent to a JSONP backend that had headers set the headers
were ignored. The JSONP backend will now throw an error if it
receives a request that has any headers set. Any uses of JSONP
on requests with headers set will need to remove the headers
to avoid the error.
platform-browser
This change may cause a breaking change in unit tests that are implicitly depending on a specific
number and sequence of change detections in order for their assertions to pass.
This may break invalid calls to TransferState methods.
This tightens parameter types of TransferState usage, and is a minor breaking change which may reveal existing problematic calls.
router
The type of Route.pathMatch is now stricter. Places that use
pathMatch will likely need to be updated to have an explicit
Route/Routes type so that TypeScript does not infer the type as
string.
When returning a Promise from the
LoadChildrenCallback, the possible type is now restricted to
Type<any>|NgModuleFactory<any> rather than any.
initialNavigation: 'enabled' was deprecated in v11 and is replaced by
initialNavigation: 'enabledBlocking'.
The type of component on ActivatedRoute and ActivatedRouteSnapshot
includes string. In reality, this is not the case. The component
cannot be anything other than a component class.
The type of initialUrl is set to string|UrlTree but in reality,
the Router only sets it to a value that will always be UrlTree
initialUrl is documented as "The target URL passed into the
Router#navigateByUrl() call before navigation" but the value
actually gets set to something completely different. It's set to the
current internal UrlTree of the Router at the time navigation
occurs.
With this change, there is no exact replacement for the old value of
initialUrl because it was never intended to be exposed.
Router.url is likely the best replacement for this.
In more specific use-cases, tracking the finalUrl between successful
navigations can also be used as a replacement.
Lazy loaded configs are now also validated once loaded like the
initial set of routes are. Lazy loaded modules which have invalid Route
configs will now error. Note that this is only done in dev mode so
there is no production impact of this change.
When a guard returns a UrlTree, the router would previously schedule
the redirect navigation within a setTimeout. This timeout is now removed,
which can result in test failures due to incorrectly written tests.
Tests which perform navigations should ensure that all timeouts are
flushed before making assertions. Tests should ensure they are capable
of handling all redirects from the original navigation.
Previously, resolvers were waiting to be completed
before proceeding with the navigation and the Router would take the last
value emitted from the resolver.
The router now takes only the first emitted value by the resolvers
and then proceeds with navigation. This is now consistent with Observables
returned by other guards: only the first value is used.
zone.js
in TaskTrackingZoneSpec track a periodic task until it is cancelled
The breaking change is scoped only to the plugin
zone.js/plugins/task-tracking. If you used TaskTrackingZoneSpec and
checked the pending macroTasks e.g. using (this.ngZone as any)._inner ._parent._properties.TaskTrackingZone.getTasksFor('macroTask'), then
its behavior slightly changed for periodic macrotasks. For example,
previously the setInterval macrotask was no longer tracked after its
callback was executed for the first time. Now it's tracked until
the task is explicitly cancelled, e.g with clearInterval(id).
Deprecations
common
The ngModuleFactory input of the NgComponentOutlet directive is deprecated in favor of a newly added ngModule input. The ngModule input accepts references to the NgModule class directly, without the need to resolve module factory first.
forms
The initialValueIsDefault option has been deprecated and replaced with the otherwise-identical nonNullable option, for the sake of naming consistency.
It is now deprecated to provide bothAbstractControlOptions and an async validators argument to a FormControl. Previously, the async validators would just be silently dropped, resulting in a probably buggy forms. Now, the constructor call is deprecated, and Angular will print a warning in devmode.
router
The resolver argument of the RouterOutletContract.activateWith function and the resolver field of the OutletContext class are deprecated. Passing component factory resolvers are no longer needed. The ComponentFactoryResolver-related symbols were deprecated in @angular/core package since v13.
