Variables

variable ANIMATION_MODULE_TYPE

const ANIMATION_MODULE_TYPE: InjectionToken<'NoopAnimations' | 'BrowserAnimations'>;

A [DI token](guide/glossary#di-token "DI token definition") that indicates which animations module has been loaded.

variable APP_BOOTSTRAP_LISTENER

const APP_BOOTSTRAP_LISTENER: InjectionToken<
    ((compRef: ComponentRef<any>) => void)[]
>;

A [DI token](guide/glossary#di-token "DI token definition") that provides a set of callbacks to be called for every component that is bootstrapped.
Each callback must take a ComponentRef instance and return nothing.
(componentRef: ComponentRef) => void

variable APP_ID

const APP_ID: InjectionToken<string>;

A [DI token](guide/glossary#di-token "DI token definition") representing a string ID, used primarily for prefixing application attributes and CSS styles when is being used.
The token is needed in cases when multiple applications are bootstrapped on a page (for example, using bootstrapApplication calls). In this case, ensure that those applications have different APP_ID value setup. For example:
bootstrapApplication(ComponentA, { providers: [ { provide: APP_ID, useValue: 'app-a' }, // ... other providers ... ] }); bootstrapApplication(ComponentB, { providers: [ { provide: APP_ID, useValue: 'app-b' }, // ... other providers ... ] });
By default, when there is only one application bootstrapped, you don't need to provide the APP_ID token (the ng will be used as an app ID).

variable APP_INITIALIZER

const APP_INITIALIZER: InjectionToken<
    readonly (() => Observable<unknown> | Promise<unknown> | void)[]
>;

A [DI token](guide/glossary#di-token "DI token definition") that you can use to provide one or more initialization functions.
The provided functions are injected at application startup and executed during app initialization. If any of these functions returns a Promise or an Observable, initialization does not complete until the Promise is resolved or the Observable is completed.
You can, for example, create a factory function that loads language data or an external configuration, and provide that function to the APP_INITIALIZER token. The function is executed during the application bootstrap process, and the needed data is available on startup.
See Also
- ApplicationInitStatus
  The following example illustrates how to configure a multi-provider using APP_INITIALIZER token and a function returning a promise.
  function initializeApp(): Promise<any> { return new Promise((resolve, reject) => { // Do some asynchronous stuff resolve(); }); } @NgModule({ imports: [BrowserModule], declarations: [AppComponent], bootstrap: [AppComponent], providers: [{ provide: APP_INITIALIZER, useFactory: () => initializeApp, multi: true }] }) export class AppModule {}
  It's also possible to configure a multi-provider using APP_INITIALIZER token and a function returning an observable, see an example below. Note: the HttpClient in this example is used for demo purposes to illustrate how the factory function can work with other providers available through DI.
  function initializeAppFactory(httpClient: HttpClient): () => Observable<any> { return () => httpClient.get("https://someUrl.com/api/user") .pipe( tap(user => { ... }) ); } @NgModule({ imports: [BrowserModule, HttpClientModule], declarations: [AppComponent], bootstrap: [AppComponent], providers: [{ provide: APP_INITIALIZER, useFactory: initializeAppFactory, deps: [HttpClient], multi: true }] }) export class AppModule {}

variable CHILD_HEAD

variable COMPILER_OPTIONS

const COMPILER_OPTIONS: InjectionToken<CompilerOptions[]>;

Token to provide CompilerOptions in the platform injector.

variable CONTAINERS

const CONTAINERS: string;

variable CONTEXT

const CONTEXT: number;

variable createNgModuleRef

const createNgModuleRef: <T>(
    ngModule: Type<T>,
    parentInjector?: Injector
) => NgModuleRef<T>;

The createNgModule function alias for backwards-compatibility. Please avoid using it directly and use createNgModule instead.
Deprecated
Use createNgModule instead.

variable CSP_NONCE

const CSP_NONCE: InjectionToken<string>;

Token used to configure the [Content Security Policy](https://web.dev/strict-csp/) nonce that Angular will apply when inserting inline styles. If not provided, Angular will look up its value from the ngCspNonce attribute of the application root node.

variable CUSTOM_ELEMENTS_SCHEMA

const CUSTOM_ELEMENTS_SCHEMA: SchemaMetadata;

Defines a schema that allows an NgModule to contain the following: - Non-Angular elements named with dash case (-). - Element properties named with dash case (-). Dash case is the naming convention for custom elements.

variable DECLARATION_COMPONENT_VIEW

const DECLARATION_COMPONENT_VIEW: number;

variable DECLARATION_LCONTAINER

const DECLARATION_LCONTAINER: number;

variable DECLARATION_VIEW

const DECLARATION_VIEW: number;

variable DEFAULT_CURRENCY_CODE

const DEFAULT_CURRENCY_CODE: InjectionToken<string>;

Provide this token to set the default currency code your application uses for CurrencyPipe when there is no currency code passed into it. This is only used by CurrencyPipe and has no relation to locale currency. Defaults to USD if not configured.
See the [i18n guide](guide/i18n-common-locale-id) for more information.
**Deprecation notice:**
The default currency code is currently always USD but this is deprecated from v9.
**In v10 the default currency code will be taken from the current locale.**
If you need the previous behavior then set it by creating a DEFAULT_CURRENCY_CODE provider in your application NgModule:
{provide: DEFAULT_CURRENCY_CODE, useValue: 'USD'}
### Example
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic'; import { AppModule } from './app/app.module'; platformBrowserDynamic().bootstrapModule(AppModule, { providers: [{provide: DEFAULT_CURRENCY_CODE, useValue: 'EUR' }] });

variable defineInjectable

const defineInjectable: <T>(opts: {
    token: unknown;
    providedIn?: Type<any> | 'root' | 'platform' | 'any' | 'environment';
    factory: () => T;
}) => unknown;

Deprecated
in v8, delete after v10. This API should be used only by generated code, and that code should now use ɵɵdefineInjectable instead.

variable DEHYDRATED_VIEWS

const DEHYDRATED_VIEWS: number;

variable DESCENDANT_VIEWS_TO_REFRESH

const DESCENDANT_VIEWS_TO_REFRESH: number;

variable DISCONNECTED_NODES

const DISCONNECTED_NODES: string;

const ELEMENT_CONTAINERS: string;

Keys within serialized view data structure to represent various parts. See the SerializedView interface below for additional information.

variable ELEMENT_MARKER

const ELEMENT_MARKER: ELEMENT_MARKER;

Marks that the next string is an element name.
See I18nMutateOpCodes documentation.

variable EMBEDDED_VIEW_INJECTOR

const EMBEDDED_VIEW_INJECTOR: number;

variable ENVIRONMENT

    new (isAsync?: boolean): EventEmitter<any>;
    new <T>(isAsync?: boolean): EventEmitter<T>;
    readonly prototype: EventEmitter<any>;
};

variable FLAGS

const FLAGS: number;

variable HAS_TRANSPLANTED_VIEWS

const HAS_TRANSPLANTED_VIEWS: number;

Flag to signify that this LContainer may have transplanted views which need to be change detected. (see: LView[DECLARATION_COMPONENT_VIEW]).
This flag, once set, is never unset for the LContainer. This means that when unset we can skip a lot of work in refreshEmbeddedViews. But when set we still need to verify that the MOVED_VIEWS are transplanted and on-push.

variable Host

const Host: HostDecorator;

Host decorator and metadata.

variable HOST

const HOST: number;

variable HostBinding

const HostBinding: HostBindingDecorator;

variable HostListener

const HostListener: HostListenerDecorator;

Decorator that binds a DOM event to a host listener and supplies configuration metadata. Angular invokes the supplied handler method when the host element emits the specified event, and updates the bound element with the result.

If the handler method returns false, applies preventDefault on the bound element.

The following example declares a directive that attaches a click listener to a button and counts clicks.

@Directive({selector: 'button[counting]'})
class CountClicks {
  numberOfClicks = 0;

  @HostListener('click', ['$event.target'])
  onClick(btn) {
    console.log('button', btn, 'number of clicks:', this.numberOfClicks++);
  }
}

@Component({
  selector: 'app',
  template: '<button counting>Increment</button>',
})
class App {}

The following example registers another DOM event handler that listens for Enter key-press events on the global window.

import { HostListener, Component } from "@angular/core";

@Component({
  selector: 'app',
  template: `<h1>Hello, you have pressed enter {{counter}} number of times!</h1> Press enter key
to increment the counter.
  <button (click)="resetCounter()">Reset Counter</button>`
})
class AppComponent {
  counter = 0;
  @HostListener('window:keydown.enter', ['$event'])
  handleKeyDown(event: KeyboardEvent) {
    this.counter++;
  }
  resetCounter() {
    this.counter = 0;
  }
}

The list of valid key names for keydown and keyup events can be found here: https://www.w3.org/TR/DOM-Level-3-Events-key/#named-key-attribute-values

Note that keys can also be combined, e.g. @HostListener('keydown.shift.a').

The global target names that can be used to prefix an event name are document:, window: and body:.

variable Input

const Input: InputDecorator;

variable ITS_JUST_ANGULAR

const ITS_JUST_ANGULAR: boolean;

See the [i18n guide](guide/i18n-common-locale-id) for more information.

### Example

import { LOCALE_ID } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/app.module';

platformBrowserDynamic().bootstrapModule(AppModule, {
  providers: [{provide: LOCALE_ID, useValue: 'en-US' }]
});

variable NATIVE

const NATIVE: number;

variable NEXT

const NEXT: number;

variable NgModule

const NgModule: NgModuleDecorator;

variable NO_ERRORS_SCHEMA

const NO_ERRORS_SCHEMA: SchemaMetadata;

Defines a schema that allows any property on any element.
This schema allows you to ignore the errors related to any unknown elements or properties in a template. The usage of this schema is generally discouraged because it prevents useful validation and may hide real errors in your template. Consider using the CUSTOM_ELEMENTS_SCHEMA instead.

const ɵNOT_FOUND_CHECK_ONLY_ELEMENT_INJECTOR: {};

variable ɵTESTABILITY

const ɵTESTABILITY: InjectionToken<Testability>;

Internal injection token that can used to access an instance of a Testability class.
This token acts as a bridge between the core bootstrap code and the Testability class. This is needed to ensure that there are no direct references to the Testability class, so it can be tree-shaken away (if not referenced). For the environments/setups when the Testability class should be available, this token is used to add a provider that references the Testability class. Otherwise, only this token is retained in a bundle, but the Testability class is not.

variable ɵTESTABILITY_GETTER

const ɵTESTABILITY_GETTER: InjectionToken<GetTestability>;

Internal injection token to retrieve Testability getter class instance.

Asserts that the current stack frame is within an injection context and has access to inject.
Parameter debugFn
a reference to the function making the assertion (used for the error message).

function assertPlatform

assertPlatform: (requiredToken: any) => PlatformRef;

Checks that there is currently a platform that contains the given token as a provider.

function computed

computed: <T>(
    computation: () => T,
    options?: CreateComputedOptions<T>
) => Signal<T>;

Create a computed Signal which derives a reactive value from an expression.

function createComponent

    component: Type<C>,
    options: {
        environmentInjector: EnvironmentInjector;
        hostElement?: Element;
        elementInjector?: Injector;
        projectableNodes?: Node[][];
    }
) => ComponentRef<C>;

Creates a ComponentRef instance based on provided component type and a set of options.
The example below demonstrates how the createComponent function can be used to create an instance of a ComponentRef dynamically and attach it to an ApplicationRef, so that it gets included into change detection cycles.
Note: the example uses standalone components, but the function can also be used for non-standalone components (declared in an NgModule) as well.
@Component({ standalone: true, template: `Hello {{ name }}!` }) class HelloComponent { name = 'Angular'; } @Component({ standalone: true, template: `<div id="hello-component-host"></div>` }) class RootComponent {} // Bootstrap an application. const applicationRef = await bootstrapApplication(RootComponent); // Locate a DOM node that would be used as a host. const host = document.getElementById('hello-component-host'); // Get an `EnvironmentInjector` instance from the `ApplicationRef`. const environmentInjector = applicationRef.injector; // We can now create a `ComponentRef` instance. const componentRef = createComponent(HelloComponent, {host, environmentInjector}); // Last step is to register the newly created ref using the `ApplicationRef` instance // to include the component view into change detection cycles. applicationRef.attachView(componentRef.hostView);
Parameter component
Component class reference.
Parameter options
Set of options to use: * environmentInjector: An EnvironmentInjector instance to be used for the component, see additional info about it [here](/guide/standalone-components#environment-injectors). * hostElement (optional): A DOM node that should act as a host node for the component. If not provided, Angular creates one based on the tag name used in the component selector (and falls back to using div if selector doesn't have tag name info). * elementInjector (optional): An ElementInjector instance, see additional info about it [here](/guide/hierarchical-dependency-injection#elementinjector). * projectableNodes (optional): A list of DOM nodes that should be projected through [<ng-content>](api/core/ng-content) of the new component instance.

function forwardRef

forwardRef: (forwardRefFn: ForwardRefFn) => Type<any>;

Allows to refer to references which are not yet defined.

For instance, forwardRef is used when the token which we need to refer to for the purposes of DI is declared, but not yet defined. It is also used when the token which we use when creating a query is not yet defined.

forwardRef is also used to break circularities in standalone components imports.

### Circular dependency example

### Circular standalone reference import example

@Component({
  standalone: true,
  imports: [ChildComponent],
  selector: 'app-parent',
  template: `<app-child [hideParent]="hideParent"></app-child>`,
})
export class ParentComponent {
  @Input() hideParent: boolean;
}


@Component({
  standalone: true,
  imports: [CommonModule, forwardRef(() => ParentComponent)],

Providers extracted via importProvidersFrom are only usable in an application injector or another environment injector (such as a route injector). They should not be used in component providers.
More information about standalone components can be found in [this guide](guide/standalone-components).
The results of the importProvidersFrom call can be used in the bootstrapApplication call:
await bootstrapApplication(RootComponent, { providers: [ importProvidersFrom(NgModuleOne, NgModuleTwo) ] });
You can also use the importProvidersFrom results in the providers field of a route, when a standalone component is used:

Given the following DOM structure:
<app-root> <button my-button></button> <my-comp></my-comp> </app-root>
Calling getDirectives on <button> will return an array with an instance of the MyButton directive that is associated with the DOM node.

function ɵgetLContext

ɵgetLContext: (target: any) => ɵLContext | null;

Returns the matching LContext data for a given DOM node, directive or component instance.
This function will examine the provided DOM element, component, or directive instance's monkey-patched property to derive the LContext data. Once called then the monkey-patched value will be that of the newly created LContext.
If the monkey-patched value is the LView instance then the context value for that target will be created and the monkey-patch reference will be updated. Therefore when this function is called it may mutate the provided element's, component's or any of the associated directive's monkey-patch values.
If the monkey-patch value is not detected then the code will walk up the DOM until an element is found which contains a monkey-patch reference. When that occurs then the provided element will be updated with a new context (which is then returned). If the monkey-patch value is not detected for a component/directive instance then it will throw an error (all components and directives should be automatically monkey-patched by ivy).
Parameter target
Component, Directive or DOM Node.

ɵɵCopyDefinitionFeature: (
    definition: ɵDirectiveDef<any> | ɵComponentDef<any>
) => void;

Copies the fields not handled by the ɵɵInheritDefinitionFeature from the supertype of a definition.
This exists primarily to support ngcc migration of an existing View Engine pattern, where an entire decorator is inherited from a parent to a child class. When ngcc detects this case, it generates a skeleton definition on the child class, and applies this feature.
The ɵɵCopyDefinitionFeature then copies any needed fields from the parent class' definition, including things like the component template function.
Parameter definition
The definition of a child class which inherits from a parent class with its own definition.

    token: unknown;
    providedIn?: Type<any> | 'root' | 'platform' | 'any' | 'environment' | null;
    factory: () => T;
}) => unknown;

Construct an injectable definition which defines how a token will be constructed by the DI system, and in which injectors (if any) it will be available.
This should be assigned to a static ɵprov field on a type, which will then be an InjectableType.
Options: * providedIn determines which injectors will include the injectable, by either associating it with an @NgModule or other InjectorType, or by specifying that this injectable should be provided in the 'root' injector, which will be the application-level injector in most apps. * factory gives the zero argument function which will create an instance of the injectable. The factory can call inject to access the Injector and request injection of dependencies.
This instruction has been emitted by ViewEngine for some time and is deployed to npm.

function ɵɵdefineInjector

ɵɵdefineInjector: (options: { providers?: any[]; imports?: any[] }) => unknown;

Construct an InjectorDef which configures an injector.
This should be assigned to a static injector def (ɵinj) field on a type, which will then be an InjectorType.
Options:
* providers: an optional array of providers to add to the injector. Each provider must either have a factory or point to a type which has a ɵprov static property (the type must be an InjectableType). * imports: an optional array of imports of other InjectorTypes or InjectorTypeWithModules whose providers will also be added to the injector. Locally provided types will override providers from imports.

    pure?: boolean;
    standalone?: boolean;
}) => unknown;

Create a pipe definition object.

# Example

  static ɵpipe = definePipe({
    ...
  });
}

Parameter pipeDef

Pipe definition generated by the compiler

ɵɵdirectiveInject: {
    <T>(token: ProviderToken<T>): T;
    <T>(token: ProviderToken<T>, flags: InjectFlags): T;
};

For example:

class ComponentWithHostDirective {
  static ɵcmp = defineComponent({
   type: ComponentWithHostDirective,
   features: [ɵɵHostDirectivesFeature([
     SimpleHostDirective,
     {directive: AdvancedHostDirective, inputs: ['foo: alias'], outputs: ['bar']},
   ])]
 });

An optional block that matches the sub-template in which it was declared. - �#{index}(:{block})�/�/#{index}(:{block})�: *Element Placeholder*: Marks the beginning and end of DOM element that were embedded in the original translation block. The placeholder index points to the element index in the template instructions set. An optional block that matches the sub-template in which it was declared. - �*{index}:{block}�/�/*{index}:{block}�: *Sub-template Placeholder*: Sub-templates must be split up and translated separately in each angular template function.

) => string;

Handles message string post-processing for internationalization.
Handles message string post-processing by transforming it from intermediate format (that might contain some markers that we need to replace) to the final form, consumable by i18nStart instruction. Post processing steps include:
1. Resolve all multi-value cases (like [�*1:1��#2:1�|�#4:1�|�5�]) 2. Replace all ICU vars (like "VAR_PLURAL") 3. Replace all placeholders used inside ICUs in a form of {PLACEHOLDER} 4. Replace all ICU references with corresponding values (like �ICU_EXP_ICU_1�) in case multiple ICUs have the same placeholder name

) => void;

Marks a block of text as translatable.
The instructions i18nStart and i18nEnd mark the translation block in the template. The translation message is the value which is locale specific. The translation string may contain placeholders which associate inner elements and sub-templates within the translation.
The translation message placeholders are: - �{index}(:{block})�: *Binding Placeholder*: Marks a location where an expression will be interpolated into. The placeholder index points to the expression binding index. An optional block that matches the sub-template in which it was declared. - �#{index}(:{block})�/�/#{index}(:{block})�: *Element Placeholder*: Marks the beginning and end of DOM element that were embedded in the original translation block.

function ɵɵNgOnChangesFeature

ɵɵNgOnChangesFeature: <T>() => DirectiveDefFeature;

The NgOnChangesFeature decorates a component with support for the ngOnChanges lifecycle hook, so it should be included in any component that implements that hook.
If the component or directive uses inheritance, the NgOnChangesFeature MUST be included as a feature AFTER InheritDefinitionFeature, otherwise inherited properties will not be propagated to the ngOnChanges lifecycle hook.
Example usage:
static ɵcmp = defineComponent({ ... inputs: {name: 'publicName'}, features: [NgOnChangesFeature] });

function ɵɵprojection

ɵɵprojection: (
    nodeIndex: number,
    selectorIndex?: number,
    attrs?: TAttributes
) => void;

Inserts previously re-distributed projected nodes. This instruction must be preceded by a call to the projectionDef instruction.
Parameter nodeIndex
Parameter selectorIndex
: - 0 when the selector is * (or unspecified as this is the default value), - 1 based index of the selector from the projectionDef

function ɵɵprojectionDef

ɵɵprojectionDef: (projectionSlots?: ProjectionSlots) => void;

Instruction to distribute projectable nodes among occurrences in a given template. It takes all the selectors from the entire component's template and decides where each projected node belongs (it re-distributes nodes among "buckets" where each "bucket" is backed by a selector).
This function requires CSS selectors to be provided in 2 forms: parsed (by a compiler) and text, un-parsed form.
The parsed form is needed for efficient matching of a node against a given CSS selector. The un-parsed, textual form is needed for support of the ngProjectAs attribute.
Having a CSS selector in 2 different formats is not ideal, but alternatives have even more drawbacks: - having only a textual form would require runtime parsing of CSS selectors; - we can't have only a parsed as we can't re-construct textual form from it (as entered by a template author).
Parameter projectionSlots
? A collection of projection slots. A projection slot can be based on a parsed CSS selectors or set to the wildcard selector ("*") in order to match all nodes which do not match any selector. If not specified, a single wildcard selector projection slot will be defined.
