Andrew Kushnir e27b505149 fix(core): prevent infinite loops in clobbered elements check (#54425)
This commit updates HTML sanitization logic to avoid infinite loops in case clobbered elements contain fields like `nextSibling` or `parentNode`. Those fields are used for DOM traversal and this update makes sure that those calls return valid results.

Gerald Monaco eff06ea8be refactor(core): add i18nNodes in preparation for i18n hydration (#54750)
An i18n message effectively acts as a dynamic template: two elements with contiguous instruction indices won't necessarily be contiguous in the DOM.

For that reason, we need to maintain a mapping from instruction index to a physical DOM node in order to hydrate views with i18n, pointing to where hydration for that view should begin.

Paul Gschwendtner b558a01c84 fix(core): generic inference for signal inputs may break with --strictFunctionTypes (#54652)
This commit fixes that the generic inference for signal inputs may break
with `--strictFunctionTypes`.

We are not using --strictFunctionTypes` in all tests, so function parameters are always
checked bivariantly- while in 1P function parameters are checked contravariantly. This
breaks sub-typing and e.g. `InputSignal<number>` is not a subtype of `InputSignalWithTransform<unknown, number>`.

Root cause is that the input signal captures the equality function that
is exclusively concerned with the `ReadT`. And `ReadT` is never equal, or a
supertype of unknown.

Andrew Scott e3bdab12fa refactor(core): Pending effects should make the application unstable (#53835)
In zone-full applications, this is already true because effects are
scheduled inside a microtask and tracked by ZoneJS. When not using
zones, this should stay consistent on principle and for testability
reasons. A general pattern with zoneless testing will be to update state
and `await` some promise (i.e. `fixture.whenStable`, which will be
linked to `ApplicationRef.isStable`).

Alex Rickabaugh ffbafc7d4a fix(core): untrack various core operations (#54614)
One downside of implicit dependency tracking in `effect()`s is that it's easy
to for downstream code to end up running inside the effect context by accident.
For example, if an effect raises an event (e.g. by `next()`ing a `Subject`), the
subscribers to that `Observable` will run inside the effect's reactive context,
and any signals read within the subscriber will end up as dependencies of the
effect. This is why the `untracked` function is useful, to run certain
operations without incidental signal reads ending up tracked.

However, knowing when this is necessary is non-trivial. For example, injecting
a dependency might cause it to be instantiated, which would run the constructor
in the effect context unless the injection operation is untracked.

Therefore, Angular will automatically drop the reactive context within a number
of framework APIs. This commit addresses these use cases:

* creating and destroying views
* creating and destroying DI injectors
* injecting dependencies
* emitting outputs

Fixes #54548

There are likely other APIs which would benefit from this approach, but this
is a start.

Andrew Scott 69598c0c6c refactor(core): Internal render hooks trigger view refresh before executing user hooks (#54224)
This commit ensures that any internal render hooks that cause views to
become dirty again first refresh those dirty views before running user
render hooks. This ensures that user render hooks have the most complete
render state possible and stops them from needlessly executing multiple

hooks, which is to provide the safest place to place code that depends
on DOM state, especially in ways that may force a browser paint.

Andrew Scott ffe3aa1169 refactor(core): Add helper function for queuing state updates (#54224)
This adds a helper function to defer application state updates to the
first possible "safe" moment. If application-wide change detection
(ApplicationRef.tick) is currently executing when this function is used,
the callback will execute as soon as all views attached to the
`ApplicationRef` have been refreshed. Refreshing the application views
will happen again before `checkNoChanges` executes.

When a change detection is _not_ running, this state update will execute
in the microtask queue.

This function is necessary as a replacement for current
`Promise.resolve().then(() => stateUpdate())` to be zoneless compatible
while ensuring those state updates are synchronized to the DOM before
the browser repaint. Without this, updates done in `Promise.resolve(...)` would
queue another round of change detection in zoneless applications, and
this change detection could happen in the next browser frame, and cause
noticeable flicker for the user.

Additionally, this function provides a way to perform state updates that
will run on the server as well as in the browser.

Last, current applications using `ngZone: 'noop'` may not be
calling `ApplicationRef.tick` at all so this function provides a
mechanism to ensure the state update still happens by racing
a microtask with `afterNextRender` (which might never execute).

Andrew Kushnir 57123524a2 fix(core): collect providers from NgModules while rendering @defer block (#52881)
Currently, when a `@defer` block contains standalone components that import NgModules with providers, those providers are not available to components declared within the same NgModule. The problem is that the standalone injector is not created for the host component (that hosts this `@defer` block), since dependencies become defer-loaded, thus no information is available at host component creation time.

This commit updates the logic to collect all providers from all NgModules used as a dependency for standalone components used within a `@defer` block. When an instance of a defer block is created, a new environment injector instance with those providers is created.

Kristiyan Kostadinov 0a3edfb543 fix(compiler-cli): correctly detect deferred dependencies across scoped nodes (#54499)
This is based on an internal issue report.

An earlier change introduced a diagnostic to report cases where a symbol is in the `deferredImports` array, but is used eagerly. The check worked by looking through the deferred blocks in a scope, resolving the scope for each and checking if the element is within the scope. The problem is that resolving the scope won't work across scoped node boundaries. For example, if there's a control flow statement around the block or within the block but around the deferred dependency, it won't be able to resolve the scope since it isn't a direct child, e.g.

```
@if (true) {
  @defer {
   <deferred-dep/>
  }
}
```

To fix this the case where the deferred block is inside a scoped node, I've changed the `R3BoundTarget.deferBlocks` to be a `Map` holding both the deferred block and its corresponding scope. Then to resolve the case where the dependency is within a scoped node inside the deferred block, I've added a depth-first traversal through the scopes within the deferred block.

- Angular DevTools is able to ask the background script to list each frame that has been registered on a page.
- Angular Devtools is able to ask the background script to "enable" the connection on a particular frame. This enables the messaging between the content script <-> background script <-> devtools page
- Implements detection of non unique urls on the inspected page

Limitations:
- The `inspectedWindow.eval` API is only able to target frames by frameURL. This means some features that integrate with Chrome DevTools like inspect element and open source will not be available when inspecting frames that do not have a unique url on the page.

Modifies the messaging layer of devtools to allow for switching communication between frames on a page. When served as a browser extension.

Design:
- When a page renders, DevTools installs a content script onto it through it's manifest file. The all_frames option is used here to install this script onto every frame in a page.
- When Angular is detected, the content script will install a backend script into it's frame.
- Each content script / backend script pairing is kept track of in the background script. This pairing represents an angular devtools context in a particular frame.
- Angular DevTools is able to ask the background script to list each frame that has been registered on a page.
- Angular Devtools is able to ask the background script to "enable" the connection on a particular frame. This enables the messaging between the content script <-> background script <-> devtools page

Kristiyan Kostadinov 78b48cc272 refactor(compiler-cli): do not emit signal unwrap calls in versions older than 17.2 (#54423)
In order to allow both signals and non-signals in two-way bindings, we have to pass the expression through `ɵunwrapWritableSignal`. The problem is that the language service uses a bundled compiler that is fairly new, but it may be compiling an older version of Angular that doesn't expose `ɵunwrapWritableSignal` (see https://github.com/angular/vscode-ng-language-service/issues/2001).

These changes add a `_angularCoreVersion` flag to the compiler which the language service can use to pass the parsed Angular version to the compiler which can then decide whether to emit the function.

## Scenarios
### Loading a project
1. The page responsible for the embedded editor lazy loads the [`EmbeddedEditor`](./embedded-editor.component.ts) component and the [`NodeRuntimeSandbox`](./node-runtime-sandbox.service.ts), then triggers the initialization of all components and services. The embedded editor is available in the following pages:
- homepage: https://angular.dev
- playground: https://angular.dev/playground
- tutorial pages: https://angular.dev/tutorials
2. The project assets are fetched by the [`EmbeddedTutorialManager`](./embedded-tutorial-manager.service.ts). Meanwhile:
- The code editor is initialized
- The code editor initializes the TypeScript Web Worker, which initializes the "default file system map" using TypeScript's CDN.
- The WebContainer is initialized
- The terminal is initialized
3. The tutorial source code is mounted in the `WebContainer`'s filesystem by the [`NodeRuntimeSandbox`](./node-runtime-sandbox.service.ts)
4. The tutorial project dependencies are installed by the [`NodeRuntimeSandbox`](./node-runtime-sandbox.service.ts).
5. The development server is started by the [`NodeRuntimeSandbox`](./node-runtime-sandbox.service.ts) and the types are loaded by the [`TypingsLoader`](./typings-loader.service.ts) service.
6. The preview is loaded with the URL provided by the WebContainer API after the development server is started.
7. The project is ready.
### Updating the code
1. The user update the code in the code editor.
2. The code editor state is updated on real time, without debouncing so that the user can see the changes in the code editor and CodeMirror can handle the changes accordingly.
3. At the same time, the changes are sent to the TypeScript web worker to provide diagnostics, autocomplete and type features as soon as possible.
4. The code changes are debounced to be written in the WebContainer filesystem by the [`NodeRuntimeSandbox`](./node-runtime-sandbox.service.ts).
5. After the debounce time is reached, the code changes are written in the WebContainer filesystem by the [`NodeRuntimeSandbox`](./node-runtime-sandbox.service.ts), then the user can see the changes in the preview.
### Creating a new file
1. The user clicks on the new file button.
2. The new file tab is opened.
3. The user types the new file name.
4. If the file name is valid, the file is created in the WebContainer filesystem by the [`NodeRuntimeSandbox`](./node-runtime-sandbox.service.ts).
- `..` is disallowed in the file name to prevent users to create files outside the `src` directory.
5. The file is added to the TypeScript virtual file system, allowing the TypeScript web worker to provide diagnostics, autocomplete and type features for the new file. Also, exports from the new file are available in other files.
6. The new file is added as the last tab in the code editor and the new file can be edited.
Note: If the new file name matches a file that already exists but is hidden in the code editor, the content for that file will show up in the created file. An example for a file that always exists is `index.html`.
### Deleting a file
1. The user clicks on the delete file button.
2. The file is deleted from the WebContainer filesystem by the [`NodeRuntimeSandbox`](./node-runtime-sandbox.service.ts).
3. The file is removed from the TypeScript virtual file system.
4. The file is removed from the code editor tabs.
Note: Some files can't be deleted to prevent users to break the app, being `src/main.ts`and `src/index.html`
### Switching a project
The embedded editor considers a project change when the embedded editor was already initialized and the user changes the page in the following scenarios:
- Navigating through tutorial steps
- Going from the homepage after the embedded editor is initialized to the playground
- Going from a tutorial page to the playground
- Going from a tutorial page to the homepage
- Going from the playground to the homepage
When a project change is detected, the [`EmbeddedTutorialManager`](./embedded-tutorial-manager.service.ts) emits the `tutorialChanged` observable, which is listened in multiple sub-components and services, then each component/service performs the necessary operations to switch the project.
The following steps are executed on project change:
1. The new project files are fetched by the [`EmbeddedTutorialManager`](./embedded-tutorial-manager.service.ts).
2. The new project files are mounted in the WebContainer filesystem.
3. The TypeScript virtual filesystem is updated with the new files and contents.
4. The previous project and new project files are compared.
1. Files that are not available in the new project are deleted from the WebContainer filesystem.
2. Files that have the same path and name have their content replaced on the previous step when the files are mounted.
5. The previous project dependencies are compared with the new project dependencies.
1. If there are differences, a `npm install` is triggered, hiding the preview and going to the install loading step.
2. If there are no differences, the project is ready.
6. Some states are resetted, for example the "reveal answer" state if the previous project was in the "reveal answer" state.
## Components and services
### [`EmbeddedEditor`](./embedded-editor.component.ts)
The embedded editor is the parent component that holds all the components and services that compose the embedded editor.
#### [`CodeEditor`](./code-editor/code-editor.component.ts)
The component that holds the code editor view and the code editor state.
##### [`CodeMirrorEditor`](./code-editor/code-mirror-editor.service.ts)
[CodeMirror](https://codemirror.net/) is the library used to handle the code editor.
The `CodeMirrorEditor` service manages the CodeMirror instance and all the interactions with the library used to handle the code editor.
- handle the file edits and the CodeMirror view and state
- handle the current project files in the code editor
- handle the file creations and deletions
- handle the file changes
- handle all the CodeMirror specific events and extensions
###### [TypeScript Web Worker](./code-editor/workers/typescript-vfs.worker.ts)
The TypeScript features are provided by the TypeScript web worker, that is initialized by the `CodeMirrorEditor` service.
The TypeScript web worker uses `@typescript/vfs` and the TypeScript language service to provide diagnostics, autocomplete and type features.
#### [`Preview`](./preview/preview.component.ts)
The preview component manages the `iframe` responsible for displaying the tutorial project preview, with the URL provided by the WebContainer API after the development server is started.
While the project is being initialized, the preview displays the loading state.
#### [`Terminal`](./terminal/terminal.component.ts)
[Xterm.js](https://xtermjs.org/) is the library used to handle the terminals.
The terminal component handles the Xterm.js instance for the console and for the interactive terminal.
##### [`InteractiveTerminal`](./terminal/interactive-terminal.ts)
The interactive terminal is the terminal where the user can interact with the terminal and run commands, supporting only commands for the Angular CLI.
##### Console
The console displays the output for `npm install` and `ng serve`.
#### [`NodeRuntimeSandbox`](./node-runtime-sandbox.service.ts)
Responsible for managing the WebContainer instance and all communication with its API. This service handles:
- the WebContainer instance
- all Node.js scripts
- the WebContainer filesystem, mounting the tutorial project files, writing new content, deleting and creating files.
- the terminal session, reading and processing user inputs.

The [image loaders](#configuring-an-image-loader-for-ngoptimizedimage) provider pattern is designed to be as simple as possible for the common use case of having only a single image CDN used within a component. However, it's still very possible to manage multiple image CDNs using a single provider.
To do this, we recommend writing a [custom image loader](#custom-loaders) which uses the [`loaderParams` property](#the-loaderparams-property) to pass a flag that specifies which image CDN should be used, and then invokes the appropriate loader based on that flag.
### Can you add a new built-in loader for my preferred CDN?
For maintenance reasons, we don't currently plan to support additional built-in loaders in the Angular repository. Instead, we encourage developers to publish any additional image loaders as third-party packages.

# Signal inputs
Signal inputs allow values to be bound from parent components.
Those values are exposed using a `Signal` and can change during the lifecycle of your component.
HELPFUL: Signal inputs are currently in [developer preview](/guide/releases#developer-preview).
Angular supports two variants of inputs:
**Optional inputs**
Inputs are optional by default, unless you use `input.required`.
You can specify an explicit initial value, or Angular will use `undefined` implicitly.
**Required inputs**
Required inputs always have a value of the given input type.
They are declared using the `input.required` function.
```typescript
import {Component, input} from '@angular/core';
@Component({...})
export class MyComp {
// optional
firstName = input<string>(); // InputSignal<string|undefined>
age = input(0); // InputSignal<number>
// required
lastName = input.required<string>(); // InputSignal<string>
}
```
An input is automatically recognized by Angular whenever you use the `input` or `input.required` functions as initializer of class members.
## Aliasing an input
Angular uses the class member name as the name of the input.
You can alias inputs to change their public name to be different.
```typescript
class StudentDirective {
age = input(0, {alias: 'studentAge'});
}
```
This allows users to bind to your input using `[studentAge]`, while inside your component you can access the input values using `this.age`.
## Using in templates
Signal inputs are read-only signals.
As with signals declared via `signal()`, you access the current value of the input by calling the input signal.
```html
<p>First name: {{firstName()}}</p>
<p>Last name: {{lastName()}}</p>
```
This access to the value is captured in reactive contexts and can notify active consumers, like Angular itself, whenever the input value changes.
An input signal in practice is a trivial extension of signals that you know from [the signals guide](/guide/signals).
```typescript
export class InputSignal<T> extends Signal<T> { ... }`.
```
## Deriving values
As with signals, you can derive values from inputs using `computed`.
```typescript
import {Component, input, computed} from '@angular/core';
@Component({...})
export class MyComp {
age = input(0);
// age multiplied by two.
ageMultiplied = computed(() => this.age() * 2);
}
```
Computed signals memoize values.
See more details in the [dedicated section for computed](/guide/signals#computed-signals).
## Monitoring changes
With signal inputs, users can leverage the `effect` function.
The function will execute whenever the input changes.
Consider the following example.
The new value is printed to the console whenever the `firstName` input changes.
```typescript
import {input, effect} from '@angular/core';
class MyComp {
firstName = input.required<string>();
constructor() {
effect(() => {
console.log(this.firstName());
});
}
}
```
The `console.log` function is invoked every time the `firstName` input changes.
This will happen as soon as `firstName` is available, and for subsequent changes during the lifetime of `MyComp`.
## Value transforms
You may want to coerce or parse input values without changing the meaning of the input.
Transforms convert the raw value from parent templates to the expected input type.
Transforms should be [pure functions](https://en.wikipedia.org/wiki/Pure_function).
```typescript
class MyComp {
disabled = input(false, {
transform: (value: boolean|string) => typeof value === 'string' ? value === '' : value,
});
}
```
In the example above, you are declaring an input named `disabled` that is accepting values of type `boolean` and `string`.
This is captured by the explicit parameter type of `value` in the `transform` option.
These values are then parsed to a `boolean` with the transform, resulting in booleans.
That way, you are only dealing with `boolean` inside your component when calling `this.disabled()`, while users of your component can pass an empty string as a shorthand to mark your component as disabled.
```html
<my-custom-comp disabled>
```
IMPORTANT:Do not use transforms if they change the meaning of the input, or if they are [impure](https://en.wikipedia.org/wiki/Pure_function#Impure_functions).
Instead, use `computed` for transformations with different meaning, or an `effect` for impure code that should run whenever the input changes.
## Why should we use signal inputs and not `@Input()`?
Signal inputs are a reactive alternative to decorator-based `@Input()`.
In comparison to decorator-based `@Input`, signal inputs provide numerous benefits:
1. Signal inputs are more **type safe**:
<br/>• Required inputs do not require initial values, or tricks to tell TypeScript that an input _always_ has a value.
<br/>• Transforms are automatically checked to match the accepted input values.
2. Signal inputs, when used in templates, will **automatically** mark `OnPush` components as dirty.
3. Values can be easily **derived** whenever an input changes using `computed`.
4. Easier and more local monitoring of inputs using `effect` instead of `ngOnChanges` or setters.

# Model inputs
**Model inputs** are a special type of input that enable a component to propagate new values
back to another component.
HELPFUL: Model inputs are currently in [developer preview](/guide/releases#developer-preview).
When creating a component, you can define a model input similarly to how you create a standard
input.
```typescript
import {Component, model, input} from '@angular/core';
@Component({...})
export class CustomCheckbox {
// This is a model input.
checked = model(false);
// This is a standard input.
disabled = input(false);
}
```
Both types of input allow someone to bind a value into the property. However, **model inputs allow
the component author to write values into the property**.
In other respects, you can use model inputs the same way you use standard inputs. You can read the
value by calling the signal function, including in reactive contexts like `computed` and `effect`.
```typescript
import {Component, model, input} from '@angular/core';
@Component({
selector: 'custom-checkbox',
template: '<div (click)="toggle()"> ... </div>',
})
export class CustomCheckbox {
checked = model(false);
disabled = input(false);
toggle() {
// While standard inputs are read-only, you can write directly to model inputs.
this.checked.set(!this.checked());
}
}
```
When a component writes a new value into a model input, Angular can propagate the new value back
to the component that is binding a value into that input. This is called **two-way binding** because
values can flow in both directions.
## Two-way binding with signals
You can bind a writable signal to a model input.
```typescript
@Component({
...,
// `checked` is a model input.
// The parenthesis-inside-square-brackets syntax (aka "banana-in-a-box") creates a two-way binding
template: '<custom-checkbox [(checked)]="isAdmin" />',
})
export class UserProfile {
protected isAdmin = signal(false);
}
```
In the above example, the `CustomCheckbox` can write values into its `checked` model input, which
then propagates those values back to the `isAdmin` signal in `UserProfile`. This binding keeps that
values of `checked` and `isAdmin` in sync. Notice that the binding passes the `isAdmin` signal
itself, not the _value_ of the signal.
## Two-way binding with plain properties
You can bind a plain JavaScript property to a model input.
```typescript
@Component({
...,
// `checked` is a model input.
// The parenthesis-inside-square-brackets syntax (aka "banana-in-a-box") creates a two-way binding
template: '<custom-checkbox [(checked)]="isAdmin" />',
})
export class UserProfile {
protected isAdmin = false;
}
```
In the example above, the `CustomCheckbox` can write values into its `checked` model input, which
then propagates those values back to the `isAdmin` property in `UserProfile`. This binding keeps
that values of `checked` and `isAdmin` in sync.
## Implicit `change` events
When you declare a model input in a component or directive, Angular automatically creates a
corresponding [output](/guide/inputs-outputs) for that model. The output's name is the model
input's name suffixed with "Change".
```typescript
@Directive({...})
export class CustomCheckbox {
// This automatically creates an output named "checkedChange".
// Can be subscribed to using `(checkedChange)="handler()"` in the template.
checked = model(false);
}
```
Angular emits this change event whenever you write a new value into the model input by calling
its `set` or `update` methods.
## Customizing model inputs
You can mark a model input as required or provide an alias in the same way as a
[standard input](/guide/signal-inputs).
Model inputs do not support input transforms.
## Differences between `model()` and `input()`
Both `input()` and `model()` functions are ways to define signal-based inputs in Angular, but they
differ in a few ways:
1. `model()` defines **both** an input and an output. The output's name is always the name of the
input suffixed with `Change` to support two-way bindings. It will be up to the consumer of your
directive to decide if they want to use just the input, just the output, or both.
2. `ModelSignal` is a `WritableSignal` which means that its value can be changed from anywhere
using the `set` and `update` methods. When a new value is assigned, the `ModelSignal` will emit
to its output. This is different from `InputSignal` which is read-only and can only be changed
through the template.
3. Model inputs do not support input transforms while signal inputs do.
## When to use model inputs
Use model inputs in components that exist to modify a value based on user interaction.
Custom form controls, such as a date picker or combobox, should use model inputs for their
primary value.
Avoid using model inputs as a convenience to avoid introducing an additional class property for
containing local state.

# Signal queries
A component or directive can define queries that find child elements and read values from their injectors.
Developers most commonly use queries to retrieve references to components, directives, DOM elements, and more.
There are two categories of query: view queries and content queries.
Signal queries supply query results as a reactive signal primitive. You can use query results in `computed` and `effect`, composing these results with other signals.
IMPORTANT: Signal queries are in [developer preview](reference/releases#developer-preview). APIs may change based on feedback without going through Angular's deprecation cycle.
If you're already familiar with Angular queries, you can jump straight to [Comparing signal-based queries to decorator-based queries](#comparing-signal-based-queries-to-decorator-based-queries)
## View queries
View queries retrieve results from the elements in the component's own template (view).
### `viewChild`
You can declare a query targeting a single result with the `viewChild` function.
```ts
@Component({
template: `
<div #el></div>
<my-component />
`
})
export class TestComponent {
// query for a single result by a string predicate
divEl = viewChild<ElementRef>('el'); // Signal<ElementRef|undefined>
// query for a single result by a type predicate
cmp = viewChild(MyComponent); // Signal<MyComponent|undefined>
}
```
### `viewChildren`
You can also query for multiple results with the `viewChildren` function.
```ts
@Component({
template: `
<div #el></div>
@if (show) {
<div #el></div>
}
`
})
export class TestComponent {
show = true;
// query for multiple results
divEls = viewChildren<ElementRef>('el'); // Signal<ReadonlyArray<ElementRef>>
}
```
### View query options
The `viewChild` and the `viewChildren` query declaration functions have a similar signature accepting two arguments:
* a **locator** to specify the query target - it can be either a `string` or any injectable token
* a set of **options** to adjust behavior of a given query.
Signal-based view queries accept only one option: `read`. The `read` option indicates the type of result to inject from the matched nodes and return in the final results.
```ts
@Component({
template: `<my-component/>`
})
export class TestComponent {
// query for a single result with options
cmp = viewChild(MyComponent, {read: ElementRef}); // Signal<ElementRef|undefined>
}
```
## Content queries
Content queries retrieve results from the elements in the component's content — the elements nested inside the component tag in the template where it's used.
### `contentChild`
You can query for a single result with the `contentChild` function.
```ts
@Component({...})
export class TestComponent {
// query by a string predicate
headerEl = contentChild<ElementRef>('h'); // Signal<ElementRef|undefined>
// query by a type predicate
header = contentChild(MyHeader); // Signal<MyHeader|undefined>
}
```
### `contentChildren`
You can also query for multiple results with the `contentChildren` function.
```ts
@Component({...})
export class TestComponent {
// query for multiple results
divEls = contentChildren<ElementRef>('h'); // Signal<ReadonlyArray<ElementRef>>
}
```
### Content query options
The `contentChild` and the `contentChildren` query declaration functions have a similar signature accepting two arguments:
* a **locator** to specify the query target - it can be either a `string` or any injectable token
* a set of **options** to adjust behavior of a given query.
Content queries accept the following options:
* `descendants` By default, content queries find only direct children of the component and do not traverse into descendants. If this option is changed to `true`, query results will include all descendants of the element. Even when `true`, however, queries _never_ descend into components.
* `read` indicates the type of result to retrieve from the matched nodes and return in the final results.
### Required child queries
If a child query (`viewChild` or `contentChild`) does not find a result, its value is `undefined`. This may occur if the target element is hidden by a control flow statement like`@if` or `@for`.
Because of this, the child queries return a signal that potentially have the `undefined` value. Most of the time, and especially for the view child queries, developers author their code such that:
* there is at least one matching result;
* results are accessed when the template was processed and query results are available.
For such cases, you can mark child queries as `required` to enforce presence of at least one matching result. This eliminates `undefined` from the result type signature. If a `required` query does not find any results, Angular throws an error.
```ts
@Component({
selector: 'app-root',
standalone: true,
template: `
<div #requiredEl></div>
`,
})
export class App {
existingEl = viewChild.required('requiredEl'); // required and existing result
missingEl = viewChild.required('notInATemplate'); // required but NOT existing result
ngAfterViewInit() {
console.log(this.existingEl()); // OK :-)
console.log(this.missingEl()); // Runtime error: result marked as required by not available!
}
}
```
## Results availability timing
A signal query authoring functions will be executed as part of the directive instance construction. This happens before we could create a query instance and execute the template’s creation mode to collect any matches. As a consequence, there is a period of time where the signal instance was created (and can be read) but no query results could have been collected. By default Angular will return `undefined` (for child queries) or an empty array (for children queries) before results are available. Required queries will throw if accessed at this point.
Angular computes signal-based query results lazily, on demand. This means that query results are not collected unless there is a code path that reads the signal.
Query results can change over time due to the view manipulation - either through the Angular's control flow (`@if`, `@for` etc.) or by the direct calls to the `ViewContainerRef` API. When you read the value from the query result signal, you can receive different values over time.
Note: to avoid returning incomplete query results while a template is rendered, Angular delays query resolution until it finishes rendering a given template.
## Query declarations functions and the associated rules
The `viewChild`, `contentChild`, `viewChildren` and `contentChildren` functions are special function recognized by the Angular compiler. You can use those functions to declare queries by initializing a component or a directive property. You can never call these functions outside of component and directive property initializers.
```ts
@Component({
selector: 'app-root',
standalone: true,
template: `
<div #el></div>
`,
})
export class App {
el = viewChild('el'); // all good!
constructor() {
const myConst = viewChild('el'); // NOT SUPPORTED
}
}
```
## Comparing signal-based queries to decorator-based queries
Signal queries are an alternative approach to the queries declared using the `@ContentChild`, `@ContentChildren`, `@ViewChild` or `@ViewChildren` decorators. The new approach exposes query results as signals which means that query results can be composed with other signals (using `computed` or `effect`) and drive change detection. Additionally, the signal-based query system offers other benefits:
* **More predictable timing.** You can access query results as soon as they're available.
* **Simpler API surface.** All queries return a signal, and queries with more than one result let you work with a standard array.
* **Improved type safety.** Fewer query use cases include `undefined` in the possible results.
* **More accurate type inference.** TypeScript can infer more accurate types when you use a type predicate or when you specify an explicit `read` option.
* **Lazier updates.** - Angular updates signal-based query results lazily; the framework does no work unless your code explicitly reads the query results.
The underlying query mechanism doesn't change much - conceptually Angular still creates singular "child" or plural "children" queries that target elements in a template (view) or content. The difference is in type of results and the exact timing of the results availability. The authoring format for declaring signal-based queries changed as well: the `viewChild`, `viewChildren`, `contentChild` and `contentChildren` functions used as initializer of class members are automatically recognized by Angular.

The `@for` repeatedly renders content of a block for each item in a collection. The collection can be represented as any JavaScript [iterable](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols) but there are performance advantages of using a regular `Array`.

```
### `track` for calculating difference of two collections
The value of the `track` expression determines a key used to associate array items with the views in the DOM. Having clear indication of the item identity allows Angular to execute a minimal set of DOM operations as items are added, removed or moved in a collection.
The value of the `track` expression determines a key used to associate array items with the views in the DOM. Having
clear indication of the item identity allows Angular to execute a minimal set of DOM operations as items are added,
removed or moved in a collection.
Loops over immutable data without `trackBy` are one of the most common causes for performance issues across Angular applications. Because of the potential for poor performance, the `track` expression is required for the `@for` loops. When in doubt, using `track $index` is a good default.
Using track effectively can significantly enhance your application's performance, especially in loops over data
collections.
For collections that do not undergo modifications (no items are moved, added, or deleted), using `track $index` is an
efficient strategy. For collections with mutable data or frequent changes, select a property that uniquely identifies
each item to use as your track expression.
Be aware of the potential for increased DOM re-creation when using object identity as a track key with immutable data
structures, as this can lead to unnecessary performance costs.
### `$index` and other contextual variables
Inside `@for` contents, several implicit variables are always available:
| Variable | Meaning |
| -------- | ------- |
| Variable | Meaning |
|----------|-----------------------------------------------|
| `$count` | Number of items in a collection iterated over |
| `$index` | Index of the current row |
| `$first` | Whether the current row is the first row |
| `$last` | Whether the current row is the last row |
| `$even` | Whether the current row index is even |
| `$odd` | Whether the current row index is odd |

| `$last` | Whether the current row is the last row |
| `$even` | Whether the current row index is even |
| `$odd` | Whether the current row index is odd |
These variables are always available with these names, but can be aliased via a `let` segment:

<h3> track and objects identity </h3>
The value of the `track` expression determines a key used to associate array items with the views in the DOM. Having clear indication of the item identity allows Angular to execute a minimal set of DOM operations as items are added, removed or moved in a collection.

operations as items are added, removed or moved in a collection.
Loops over immutable data without `trackBy` as one of the most common causes for performance issues across Angular applications. Because of the potential for poor performance, the `track` expression is required for the `@for` loops. When in doubt, using `track $index` is a good default.
To optimize performance, especially in loops over immutable data, ensure the track expression is effectively used to
identify each item uniquely. Because of the potential for poor performance, the `track` expression
is required for the `@for` loops.
For collections that remain static , `track $index` provides a straightforward tracking mechanism. For dynamic
collections experiencing additions, deletions, or reordering, opt for a
unique property of each item as the tracking key.
<h3> `$index` and other contextual variables </h3>
Inside `@for` contents, several implicit variables are always available:

These variables are always available with these names, but can be aliased via a `let` segment:
```html
@for (item of items; track item.id; let idx = $index, e = $even) {
Item #{{ idx }}: {{ item.name }}
Item #{{ idx }}: {{ item.name }}
}
```
The aliasing is especially useful in case of using nested `@for` blocks where contextual variable names could collide.

# Model inputs
**Model inputs** are a special type of input that enable a component to propagate new values
back to another component.
<div class="alert is-helpful">
Model inputs are currently in [developer preview](/guide/releases#developer-preview).
</div>
When creating a component, you can define a model input similarly to how you create a standard
input.
```typescript
import {Component, model, input} from '@angular/core';
@Component({...})
export class CustomCheckbox {
// This is a model input.
checked = model(false);
// This is a standard input.
disabled = input(false);
}
```
Both types of input allow someone to bind a value into the property. However, **model inputs allow
the component author to write values into the property**.
In other respects, you can use model inputs the same way you use standard inputs. You can read the
value by calling the signal function, including in reactive contexts like `computed` and `effect`.
```typescript
import {Component, model, input} from '@angular/core';
@Component({
selector: 'custom-checkbox',
template: '<div (click)="toggle()"> ... </div>',
})
export class CustomCheckbox {
checked = model(false);
disabled = input(false);
toggle() {
// While standard inputs are read-only, you can write directly to model inputs.
this.checked.set(!this.checked());
}
}
```
When a component writes a new value into a model input, Angular can propagate the new value back
to the component that is binding a value into that input. This is called **two-way binding** because
values can flow in both directions.
## Two-way binding with signals
You can bind a writable signal to a model input.
```typescript
@Component({
...,
// `checked` is a model input.
// The parenthesis-inside-square-brackets syntax (aka "banana-in-a-box") creates a two-way binding
template: '<custom-checkbox [(checked)]="isAdmin" />',
})
export class UserProfile {
protected isAdmin = signal(false);
}
```
In the above example, the `CustomCheckbox` can write values into its `checked` model input, which
then propagates those values back to the `isAdmin` signal in `UserProfile`. This binding keeps that
values of `checked` and `isAdmin` in sync. Notice that the binding passes the `isAdmin` signal
itself, not the _value_ of the signal.
## Two-way binding with plain properties
You can bind a plain JavaScript property to a model input.
```typescript
@Component({
...,
// `checked` is a model input.
// The parenthesis-inside-square-brackets syntax (aka "banana-in-a-box") creates a two-way binding
template: '<custom-checkbox [(checked)]="isAdmin" />',
})
export class UserProfile {
protected isAdmin = false;
}
```
In the example above, the `CustomCheckbox` can write values into its `checked` model input, which
then propagates those values back to the `isAdmin` property in `UserProfile`. This binding keeps
that values of `checked` and `isAdmin` in sync.
## Implicit `change` events
When you declare a model input in a component or directive, Angular automatically creates a
corresponding [output](/guide/inputs-outputs) for that model. The output's name is the model
input's name suffixed with "Change".
```typescript
@Directive({...})
export class CustomCheckbox {
// This automatically creates an output named "checkedChange".
// Can be subscribed to using `(checkedChange)="handler()"` in the template.
checked = model(false);
}
```
Angular emits this change event whenever you write a new value into the model input by calling
its `set` or `update` methods.
## Customizing model inputs
You can mark a model input as required or provide an alias in the same way as a
[standard input](/guide/signal-inputs).
Model inputs do not support input transforms.
## Differences between `model()` and `input()`
Both `input()` and `model()` functions are ways to define signal-based inputs in Angular, but they
differ in a few ways:
1. `model()` defines **both** an input and an output. The output's name is always the name of the
input suffixed with `Change` to support two-way bindings. It will be up to the consumer of your
directive to decide if they want to use just the input, just the output, or both.
2. `ModelSignal` is a `WritableSignal` which means that its value can be changed from anywhere
using the `set` and `update` methods. When a new value is assigned, the `ModelSignal` will emit
to its output. This is different from `InputSignal` which is read-only and can only be changed
through the template.
3. Model inputs do not support input transforms while signal inputs do.
## When to use model inputs
Use model inputs in components that exist to modify a value based on user interaction.
Custom form controls, such as a date picker or combobox, should use model inputs for their
primary value.
Avoid using model inputs as a convenience to avoid introducing an additional class property for
containing local state.

To make these transitions as straightforward as possible, we make these commitments to you:
* We work hard to minimize the number of breaking changes and to provide migration tools when possible
* We follow the deprecation policy described here, so you have time to update your applications to the latest APIs and best practices
When the Angular team intends to remove an API or feature, it will be marked as *deprecated*. This occurs when when an API is obsolete, superseded by another API, or otherwise discontinued. Deprecated API remain available through their deprecated phase, which lasts a minimum two major versions (approximately one year).
To help ensure that you have sufficient time and a clear path to update, this is our deprecation policy:

## Public API surface
## Compatibility policy
Angular is a collection of many packages, subprojects, and tools.
To prevent accidental use of private APIs and so that you can clearly understand what is covered by the practices described here &mdash; we document what is and is not considered our public API surface.
For details, see [Supported Public API Surface of Angular](https://github.com/angular/angular/blob/main/docs/PUBLIC_API.md "Supported Public API Surface of Angular").
Any changes to the public API surface are done using the versioning, support, and depreciation policies previously described.
To guarantee backward compatibility of Angular we run a series of checks before we merge any change:
* Unit tests and integration tests
* Comparing the type definitions of the public API surface before and after the change
* Running the tests of all the applications at Google that depend on Angular
Any changes to the public API surface are made in accordance with the versioning, support, and depreciation policies previously described. In exceptional cases, such as critical security patches, fixes may introduce backwards incompatible changes. Such exceptional cases are accompanied by explicit notice on the framework's official communication channels.
<a id="updating"></a>
## Breaking change policy and update paths
Breaking change requires you to do work because the state after it is not backward compatible with the state before it. You can find the rare exceptions from this rule in the [Compatibility policy](#compatibility-policy). Examples of breaking changes are the removal of public APIs or other changes of the type definition of Angular, changing the timing of calls, or updating to a new version of a dependency of Angular, which includes breaking changes itself.
To support you in case of breaking changes in Angular:
* We follow our [deprecation policy](#deprecation-policy) before we remove a public API
* Support update automation via the `ng update` command. It provides code transformations which we often have tested ahead of time over hundreds of thousands of projects at Google
* Step by step instructions how to update from one major version to another at the ["Angular Update Guide"](https://update.angular.io/)
You can `ng update` to any version of Angular, provided that the following criteria are met:
* The version you want to update *to* is supported.
* The version you want to update *from* is within one major version of the version you want to
upgrade to.
For example, you can update from version 11 to version 12, provided that version 12 is still supported.
If you want to update across multiple major versions, perform each update one major version at a time.
For example, to update from version 10 to version 12:
1. Update from version 10 to version 11.

# Signal inputs
Signal inputs allow values to be bound from parent components.
Those values are exposed using a `Signal` and can change during the lifecycle of your component.
<div class="alert is-helpful">
Signal inputs are currently in [developer preview](/guide/releases#developer-preview).
</div>
Angular supports two variants of inputs:
**Optional inputs**
Inputs are optional by default, unless you use `input.required`.
You can specify an explicit initial value, or Angular will use `undefined` implicitly.
**Required inputs**
Required inputs always have a value of the given input type.
They are declared using the `input.required` function.
```typescript
import {Component, input} from '@angular/core';
@Component({...})
export class MyComp {
// optional
firstName = input<string>(); // InputSignal<string|undefined>
age = input(0); // InputSignal<number>
// required
lastName = input.required<string>(); // InputSignal<string>
}
```
An input is automatically recognized by Angular whenever you use the `input` or `input.required` functions as initializer of class members.
## Aliasing an input
Angular uses the class member name as the name of the input.
You can alias inputs to change their public name to be different.
```typescript
class StudentDirective {
age = input(0, {alias: 'studentAge'});
}
```
This allows users to bind to your input using `[studentAge]`, while inside your component you can access the input values using `this.age`.
## Using in templates
Signal inputs are read-only signals.
As with signals declared via `signal()`, you access the current value of the input by calling the input signal.
```html
<p>First name: {{firstName()}}</p>
<p>Last name: {{lastName()}}</p>
```
This access to the value is captured in reactive contexts and can notify active consumers, like Angular itself, whenever the input value changes.
An input signal in practice is a trivial extension of signals that you know from [the signals guide](/guide/signals).
```typescript
export class InputSignal<T> extends Signal<T> { ... }`.
```
## Deriving values
As with signals, you can derive values from inputs using `computed`.
```typescript
import {Component, input, computed} from '@angular/core';
@Component({...})
export class MyComp {
age = input(0);
// age multiplied by two.
ageMultiplied = computed(() => this.age() * 2);
}
```
Computed signals memoize values.
See more details in the [dedicated section for computed](/guide/signals#computed-signals).
## Monitoring changes
With signal inputs, users can leverage the `effect` function.
The function will execute whenever the input changes.
Consider the following example.
The new value is printed to the console whenever the `firstName` input changes.
```typescript
import {input, effect} from '@angular/core';
class MyComp {
firstName = input.required<string>();
constructor() {
effect(() => {
console.log(this.firstName());
});
}
}
```
The `console.log` function is invoked every time the `firstName` input changes.
This will happen as soon as `firstName` is available, and for subsequent changes during the lifetime of `MyComp`.
## Value transforms
You may want to coerce or parse input values without changing the meaning of the input.
Transforms convert the raw value from parent templates to the expected input type.
Transforms should be [pure functions](https://en.wikipedia.org/wiki/Pure_function).
```typescript
class MyComp {
disabled = input(false, {
transform: (value: boolean|string) => typeof value === 'string' ? value === '' : value,
});
}
```
In the example above, you are declaring an input named `disabled` that is accepting values of type `boolean` and `string`.
This is captured by the explicit parameter type of `value` in the `transform` option.
These values are then parsed to a `boolean` with the transform, resulting in booleans.
That way, you are only dealing with `boolean` inside your component when calling `this.disabled()`, while users of your component can pass an empty string as a shorthand to mark your component as disabled.
```html
<my-custom-comp disabled>
```
<div class="alert is-important">
Do not use transforms if they change the meaning of the input, or if they are [impure](https://en.wikipedia.org/wiki/Pure_function#Impure_functions).
Instead, use `computed` for transformations with different meaning, or an `effect` for impure code that should run whenever the input changes.
</div>
## Why should we use signal inputs and not `@Input()`?
Signal inputs are a reactive alternative to decorator-based `@Input()`.
In comparison to decorator-based `@Input`, signal inputs provide numerous benefits:
1. Signal inputs are more **type safe**:
<br/>• Required inputs do not require initial values, or tricks to tell TypeScript that an input _always_ has a value.
<br/>• Transforms are automatically checked to match the accepted input values.
2. Signal inputs, when used in templates, will **automatically** mark `OnPush` components as dirty.
3. Values can be easily **derived** whenever an input changes using `computed`.
4. Easier and more local monitoring of inputs using `effect` instead of `ngOnChanges` or setters.

# Signal queries
A component or directive can define queries that find child elements and read values from their injectors.
Developers most commonly use queries to retrieve references to components, directives, DOM elements, and more.
There are two categories of query: view queries and content queries.
Signal queries supply query results as a reactive signal primitive. You can use query results in `computed` and `effect`, composing these results with other signals.
<div class="alert is-helpful">
Signal queries are in [developer preview](/guide/releases#developer-preview).
APIs may change based on feedback without going through Angular's deprecation cycle.
</div>
If you're already familiar with Angular queries, you can jump straight to [Comparing signal-based queries to decorator-based queries](#comparing-signal-based-queries-to-decorator-based-queries)
## View queries
View queries retrieve results from the elements in the component's own template (view).
### `viewChild`
You can declare a query targeting a single result with the `viewChild` function.
```ts
@Component({
template: `
<div #el></div>
<my-component />
`
})
export class TestComponent {
// query for a single result by a string predicate
divEl = viewChild<ElementRef>('el'); // Signal<ElementRef|undefined>
// query for a single result by a type predicate
cmp = viewChild(MyComponent); // Signal<MyComponent|undefined>
}
```
### `viewChildren`
You can also query for multiple results with the `viewChildren` function.
```ts
@Component({
template: `
<div #el></div>
@if (show) {
<div #el></div>
}
`
})
export class TestComponent {
show = true;
// query for multiple results
divEls = viewChildren<ElementRef>('el'); // Signal<ReadonlyArray<ElementRef>>
}
```
### View query options
The `viewChild` and the `viewChildren` query declaration functions have a similar signature accepting two arguments:
* a **locator** to specify the query target - it can be either a `string` or any injectable token
* a set of **options** to adjust behavior of a given query.
Signal-based view queries accept only one option: `read`. The `read` option indicates the type of result to inject from the matched nodes and return in the final results.
```ts
@Component({
template: `<my-component/>`
})
export class TestComponent {
// query for a single result with options
cmp = viewChild(MyComponent, {read: ElementRef}); // Signal<ElementRef|undefined>
}
```
## Content queries
Content queries retrieve results from the elements in the component's content — the elements nested inside the component tag in the template where it's used.
### `contentChild`
You can query for a single result with the `contentChild` function.
```ts
@Component({...})
export class TestComponent {
// query by a string predicate
headerEl = contentChild<ElementRef>('h'); // Signal<ElementRef|undefined>
// query by a type predicate
header = contentChild(MyHeader); // Signal<MyHeader|undefined>
}
```
### `contentChildren`
You can also query for multiple results with the `contentChildren` function.
```ts
@Component({...})
export class TestComponent {
// query for multiple results
divEls = contentChildren<ElementRef>('h'); // Signal<ReadonlyArray<ElementRef>>
}
```
### Content query options
The `contentChild` and the `contentChildren` query declaration functions have a similar signature accepting two arguments:
* a **locator** to specify the query target - it can be either a `string` or any injectable token
* a set of **options** to adjust behavior of a given query.
Content queries accept the following options:
* `descendants` By default, content queries find only direct children of the component and do not traverse into descendants. If this option is changed to `true`, query results will include all descendants of the element. Even when `true`, however, queries _never_ descend into components.
* `read` indicates the type of result to retrieve from the matched nodes and return in the final results.
### Required child queries
If a child query (`viewChild` or `contentChild`) does not find a result, its value is `undefined`. This may occur if the target element is hidden by a control flow statement like `@if` or `@for`.
Because of this, the child queries return a signal that potentially have the `undefined` value. Most of the time, and especially for the view child queries, developers author their code such that:
* there is at least one matching result;
* results are accessed when the template was processed and query results are available.
For such cases, you can mark child queries as `required` to enforce presence of at least one matching result. This eliminates `undefined` from the result type signature. If a `required` query does not find any results, Angular throws an error.
```ts
@Component({
selector: 'app-root',
standalone: true,
template: `
<div #requiredEl></div>
`,
})
export class App {
existingEl = viewChild.required('requiredEl'); // required and existing result
missingEl = viewChild.required('notInATemplate'); // required but NOT existing result
ngAfterViewInit() {
console.log(this.existingEl()); // OK :-)
console.log(this.missingEl()); // Runtime error: result marked as required but not available!
}
}
```
## Results availability timing
A signal query authoring functions will be executed as part of the directive instance construction. This happens before we could create a query instance and execute the template’s creation mode to collect any matches. As a consequence, there is a period of time where the signal instance was created (and can be read) but no query results could have been collected. By default Angular will return `undefined` (for child queries) or an empty array (for children queries) before results are available. Required queries will throw if accessed at this point.
Angular computes signal-based query results lazily, on demand. This means that query results are not collected unless there is a code path that reads the signal.
Query results can change over time due to the view manipulation - either through the Angular's control flow (`@if`, `@for` etc.) or by the direct calls to the `ViewContainerRef` API. When you read the value from the query result signal, you can receive different values over time.
Note: to avoid returning incomplete query results while a template is rendered, Angular delays query resolution until it finishes rendering a given template.
## Query declarations functions and the associated rules
The `viewChild`, `contentChild`, `viewChildren` and `contentChildren` functions are special function recognized by the Angular compiler. You can use those functions to declare queries by initializing a component or a directive property. You can never call these functions outside of component and directive property initializers.
```ts
@Component({
selector: 'app-root',
standalone: true,
template: `
<div #el></div>
`,
})
export class App {
el = viewChild('el'); // all good!
constructor() {
const myConst = viewChild('el'); // NOT SUPPORTED
}
}
```
## Comparing signal-based queries to decorator-based queries
Signal queries are an alternative approach to the queries declared using the `@ContentChild`, `@ContentChildren`, `@ViewChild` or `@ViewChildren` decorators. The new approach exposes query results as signals which means that query results can be composed with other signals (using `computed` or `effect`) and drive change detection. Additionally, the signal-based query system offers other benefits:
* **More predictable timing.** You can access query results as soon as they're available.
* **Simpler API surface.** All queries return a signal, and queries with more than one result let you work with a standard array.
* **Improved type safety.** Fewer query use cases include `undefined` in the possible results.
* **More accurate type inference.** TypeScript can infer more accurate types when you use a type predicate or when you specify an explicit `read` option.
* **Lazier updates.** - Angular updates signal-based query results lazily; the framework does no work unless your code explicitly reads the query results.
The underlying query mechanism doesn't change much - conceptually Angular still creates singular "child" or plural "children" queries that target elements in a template (view) or content. The difference is in type of results and the exact timing of the results availability. The authoring format for declaring signal-based queries changed as well: the `viewChild`, `viewChildren`, `contentChild` and `contentChildren` functions used as initializer of class members are automatically recognized by Angular.

This topic provides information about updating your Angular applications to Angular version 17.
For a summary of this information and the step-by-step procedure to update your Angular application
to v17, see the [Angular Update Guide](https://update.angular.io).
The information in the [Angular Update Guide](https://update.angular.io) and this topic is
summarized from these changelogs:
- [angular/angular changelog](https://github.com/angular/angular/blob/main/CHANGELOG.md)
- [angular/angular-cli changelog](https://github.com/angular/angular-cli/blob/main/CHANGELOG.md)
- [angular/components changelog](https://github.com/angular/components/blob/main/CHANGELOG.md)
Information about updating Angular applications to v16 is archived at
[Update to version 16](/guide/update-to-version-16).
<a id="new-features"></a>
## Feature highlights in Angular v17
For a more comprehensive list of new features, see the
[Angular blog post on the update to v17](https://blog.angular.io).
<!-- markdownLint-disable MD001 -->
#### Deferrable views
The new deferrable views allow you to lazily load all the components, directives, and pipes in a a section of your template:
```html
@defer (on viewport) {
<comment-list />
} @placeholder {
<!-- A placeholder content to show until the comments load -->
<img src="comments-placeholder.png" />
}
```
In the example above, Angular first renders the contents of the placeholder block. When it becomes visible in the viewport, the loading of the `<comment-list />` component starts. Once the loading is completed, Angular removes the placeholder and renders the component.
#### Built-in control flow
We used a new block syntax for an optimized, built-in control flow. After running user studies we identified that a lot of developers struggle with `*ngIf`, `*ngSwitch`, and `*ngFor`.
It includes conditional statements:
```text
@if (loggedIn) {
The user is logged in
} @else {
The user is not logged in
}
```
Switch statements:
```text
@switch (accessLevel) {
@case ('admin') { <admin-dashboard/> }
@case ('moderator') { <moderator-dashboard/> }
@default { <user-dashboard/> }
}
```
And for loop:
```text
@for (user of users; track user.id) {
{{ user.name }}
} @empty {
Empty list of users
}
```
In addition to the improved ergonomics, the control flow is also up to 90% faster for certain performance benchmarks.
As of v17, the built-in control flow is in developer preview. To update your projects to using it run the schematic:
```sh
ng generate @angular/core:control-flow
```
#### New `@angular/ssr` package
We moved the code powering Angular server-side rendering from `angular/universal` to `angular/angular-cli`, integrating SSR more directly into our tooling.
Starting today, to add SSR support to your existing application run:
```sh
ng add @angular/ssr
```
This command generates the server entry point, adds SSR and SSG build capabilities, and enables hydration by default. `@angular/ssr` provides equivalent functionality to` @nguniversal/express-engine` which is currently in maintenance mode. The Angular CLI will automatically update your code to `@angular/ssr` with `ng update`!
#### New lifecycle hooks
To improve the performance of Angular’s SSR and SSG, in the long-term we’d like to move away from DOM emulation and direct DOM manipulations. At the same time, throughout most applications’ lifecycle they need to interact with elements to instantiate third-party libraries, measure element size, etc.
To enable this, we developed a set of new lifecycle hooks:
- `afterRender` - register a callback to be invoked each time the application finishes rendering
- `afterNextRender` - register a callback to be invoked the next time the application finishes rendering
Only the browser will invoke these hooks, which enables you to plug custom DOM logic safely directly inside your components. For example, if you’d like to instantiate a charting library you can use afterNextRender:
```typescript
@Component({
selector: 'my-chart-cmp',
template: `<div #chart>{{ ... }}</div>`,
})
export class MyChartCmp {
@ViewChild('chart') chartRef: ElementRef;
chart: MyChart | null;
constructor() {
afterNextRender(() => {
this.chart = new MyChart(this.chartRef.nativeElement);
});
}
}
```
#### Vite and esbuild the default for new projects
In v16 we introduced developer preview of the esbuild plus Vite powered build experience. Since then a lot of developers experimented with it and enterprises! Today, we’re happy to announce that the new application builder graduates from developer preview and is enabled by default for all new applications!
We updated the build pipeline when using hybrid rendering. With SSR & SSG you can observe up to 87% speed improvement in ng build and 80% faster edit-refresh loop in for `ng serve`. We'll be working on schematics to switch existing applications using hybrid rendering (SSR and SSG) to the new builder.
#### Dependency injection debugging in DevTools
Over the past few months, we implemented brand new debugging APIs that allow us to plug into the framework’s runtime and inspect the injector tree.
Based on these APIs we built an inspection user interface that allows you to preview the:
- Dependencies of your components in the component inspector
- Injector tree and dependency resolution path
- Providers declared within the individual injectors
#### Experimental view transitions support
The View Transitions API enables smooth transitions when changing the DOM. In the Angular router we now provide direct support for this API via the `withViewTransitions` feature. Using this, you can use the browser's native capabilities for creating animated transitions between routes.
You can add this feature to your app today by configuring it in the router’s provider declaration during bootstrap:
```typescript
bootstrapApplication(App, {
providers: [provideRouter(routes, withViewTransitions())],
});
```
`withViewTransitions` accepts an optional configuration object with property `onViewTransitionCreated`, which is a callback that provides you some extra control:
- Decide if you’d like to skip particular animations
- Add classes to the document to customize the animation and remove these classes when the animation completes
- etc.

## Highlighted breaking changes in Angular v17
For a comprehensive list of breaking changes, see the full changelogs on GitHub.
<a id="v17-bc-01"></a>
### Angular v17 requires node.js version v18.13 or newer
Angular requires node.js v18.13 or newer.
See [Version compatibility](/guide/versions) for full version compatibility details.
<a id="v17-bc-02"></a>
### Angular v17 requires TypeScript version 5.2 or later
Angular v17 no longer supports TypeScript versions older than 5.2.
See [Version compatibility](/guide/versions) for full version compatibility details.
<a id="v17-bc-03"></a>
### Angular v17 requires zone.js v0.14.0
Angular v17 no longer supports zone.js older than v0.14.0.
<a id="v17-bc-04"></a>
#### Strict NgSwitch check
The `NgSwitch` directive now defaults to the `===` equality operator, migrating from the previously used `==`. `NgSwitch` expressions or individual condition values need adjusting to this stricter equality check. You'll see a warning message in the console where you need to adjust the check.
<a id="v17-bc-06"></a>
#### Routes with `loadComponent` data inheritance
Child routes with `loadComponent` no longer automatically inherit their data from their parent by default. In v17 the default `paramsInheritanceStrategy` is `emptyOnly`. If you want to inherit parent data in child routes update the strategy to `always`.
<a id="v17-bc-07"></a>
#### Router absolute redirect behavior change
Absolute redirects no longer prevent further redirects. You may need to adjust route configurations to prevent infinite redirects. Previously the router was ignoring all redirects after an absolute redirect.
<a id="v17-bc-08"></a>
#### Removal of `setupTestingRouter`
Use `RouterModule.forRoot` or `provideRouter` to setup the Router for tests instead of `setupTestingRouter`.
<a id="v17-bc-09"></a>
#### Removal of `malformedUriErrorHandler`
We removed `malformedUriErrorHandler` from the `RouterModule.forRoot` options. To handle URL parsing errors use the `UrlSerializer.parse` method.
<a id="v17-bc-10"></a>
#### Removal of zone.js bundles
In v17 we removed `zone-testing-bundle` and `zone-testing-node-bundle` which now prevents you from using `dist/` imports like `zone.js/bundles/zone-testing.js` and `zone.js/dist/zone`.
<a id="v17-bc-11"></a>
#### `OnPush` dynamically instantiated components
For dynamically instantiated components we now execute `ngDoCheck` during change detection if the component is marked as dirty. You may need to update your tests or logic within `ngDoCheck` for dynamically instantiated components.
<a id="v17-bc-12"></a>
#### Relocating Router public methods to `provideRouter` and `RouterModule.forRoot`
Make sure you configure `setupTestingRouter`, `canceledNavigationResolution`, `paramsInheritanceStrategy`, `titleStrategy`, `urlUpdateStrategy`, `urlHandlingStrategy`, and `malformedUriErrorHandler` in `provideRouter` or `RouterModule.forRoot` since these properties are now not part of the `Router`'s public API
<a id="v17-bc-13"></a>
#### `REMOVE_STYLES_ON_COMPONENT_DESTROY` now defaults to `true`
Angular now automatically removes styles of destroyed components, which may impact your existing apps in cases you rely on leaked styles. To change this update the value of the `REMOVE_STYLES_ON_COMPONENT_DESTROY` provider to `false`.
<a id="deprecations"></a>
## Deprecations highlights in Angular v17
These APIs remain available in v17, but may be removed in future versions as described by Angular's
[deprecation policy](/guide/releases#deprecation-policy).
To maintain the reliability of your Angular application, always update your application as soon as
practicable.
| Removed | Replacement | Details |
| :------------------------------------------- | :-------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| <a id="v17-dp-01"></a>`NgProbeToken` | None | The `NgProbeToken` is not used internally since the transition from View Engine to Ivy. The token has no utility and can be removed from applications and libraries. |
| <a id="v17-dp-02"></a>`AnimationDriver.NOOP` | `NoopAnimationDriver` | `The AnimationDriver.NOOP` symbol is deprecated, use `NoopAnimationDriver` instead. |
