Adds support for `@Input` transform functions in isolated declarations mode (`emitDeclarationOnly: true`), allowing components and directives to specify `transform` functions without triggering fatal compiler errors.
Synthesizes the `ngAcceptInputType_` write type syntactically:
- For referenced functions (`transform: booleanAttribute`), emits `Parameters<typeof booleanAttribute>[0]`, relying on downstream template type checking to resolve the type.
- For inline functions (`transform: (v: string) => boolean`), extracts `parameters[0].type` directly from the local TypeScript AST.

Removes restrictions around using external references and local directives in `hostDirectives` under isolated declarations mode (`emitDeclarationOnly: true`).
By wrapping the host directive reference in a `WrappedNodeExpr`, TypeScript's declaration emitter seamlessly emits `typeof hostReference.node`, preserving existing imports or local identifiers exactly as authored. Also adds support for translating `PropertyAccessExpression` inside `WrappedNodeExpr` into `QualifiedName` for `.d.ts` emission, ensuring namespace imports (`import * as n from './dir'`) are preserved correctly.

Mark the iframe `credentialless` attribute as security-sensitive so dynamic
bindings are handled consistently with other iframe attributes that affect the
initial navigation, such as `sandbox`, `allow`, `referrerPolicy`, `csp`, and
`fetchPriority`.
Because `credentialless` must be present before the iframe starts loading to
affect the navigation’s credential mode, late dynamic updates can leave the final
DOM looking correct while the initial request was not loaded credentiallessly.

d1539a8513 incorrectly assumed components wouldn't be abstract but
it is still possible (though probably should be an abstract directive instead).

Apply schema-derived sanitizer resolution to TwoWayProperty ops so native two-way DOM bindings emit the same sanitizer as one-way property bindings.
Add compiler compliance coverage for innerHTML, srcdoc, URL, resource URL, and security-sensitive attribute cases.

Currently we only skip regex optimization if it has the `g` flag, however regexes can also have a state with the `y` flag.
These changes move to an allowlist model where we only optimize for a set of know flags.

Update the minimum supported Node.js versions for v22 and v24. Specifically, the minimum supported version for Node.js v22 is bumped to v22.22.3, and for v24 it is bumped to v24.15.0. This ensures compatibility with newer runtime versions and coordinates ranges across monorepo packages.

Ensures that namespaced <script> elements (such as :svg:script) are correctly classified as PreparsedElementType.SCRIPT by the template preparser and stripped during compilation to prevent potential XSS vulnerabilities. Consequently, obsolete security schema mappings and runtime sanitization checks for <script> attributes have been removed since these elements are never present in compiled template outputs.

Currently if a `@for` loop doesn't have a `track` expression we don't produce an AST for it at all which means no type checking and language service support for it.
These changes make it so we produce the AST anyways since it gives the user more tools to resolve the issue (e.g. autocompletion when writing the `track` expression).

The `readFileBuffer` method in `node_js_file_system.ts` was wrapped in
`@ts-ignore` to suppress a TS2322 Buffer/Uint8Array typing error that
was fixed in the TypeScript 5.9.2 upgrade. The minimum supported
TypeScript is now 6.0, so the suppression is dead.

Convert four `.forEach()` calls in `private_export_checker.ts` and
`reference_graph.ts` to `for...of`, matching the iteration style used
elsewhere in the compiler. The TODOs that forced these workarounds are
obsolete.
(cherry picked from commit e661f4d255)
The getters and setters for jsDocParsingMode in `host.ts` and
`ts_create_program_driver.ts` were suppressed with @ts-ignore to
support TypeScript 5.2, which lacked the property on `ts.CompilerHost`.
The minimum supported TypeScript is now 6.0, and `jsDocParsingMode`
is part of the public TypeScript API, so the suppressions can go.

This allows us to show the API docs when the jsdoc block is at the top of a overloaded function (and not on the implementation signature).

Moves the event attribute validation check outside of `ngDevMode` in the `elementAttributeInternal` instruction to ensure that bindings to event attributes like `on*` are always blocked at runtime.

Rather than requiring TS AST in the indexer API, this update makes it generic with adapters to provide necessary information. This allows other analysis pipelines that don't use TS AST to work with the indexer.

* Test that `minDate`/`maxDate` binds to `min`/`max` on date and time inputs
* Test that `min`/`max` attribute can be set directly on date and time inputs
* Relax type checker to allow `min`/`max` bindings on date and time inputs
PR Close#68001
Updates the supported Node.js engine versions to include Node.js 26.
This allows running the CLI on Node.js 26.0.0 and above while continuing to support active LTS versions.
There was not a test demonstrating local compilation with the
'bootstrap' param on NgModule. This test adds one, among other NgModule
fields in one. These other fields are broadly covered already, but this
rolls them into one test exercising all fields.
This commit updates `@defer` logic related to incremental hydration to be tree-shakable.
If hydrate triggers are used in a `@defer` block, the compiler emits a single top-level call to `ɵɵenableIncrementalHydrationRuntime`, placed once per create block before the first `ɵɵdefer` that requires it.
As a result, the incremental hydration runtime is only included in the bundle when hydrate is explicitly used.
This change adds a new that allows environments that cannot support inline TCBs (such as the language service or source-to-source transforms where TS compilation and emit are downstream) to still perform template type checking.
Instead of inlining the TCB into the original source file when non-exported symbols are referenced, we now copy the file content to the .ngtypecheck.ts shim file and generate the external TCB there, if requested by the inlining mode. This preserves the local scope of the original file while keeping the original file unmodified.
all necessary info is already available in the tcb meta objects. environments without full ts program no longer need a reflectionhost for tcb generation
Removes the `checkTwoWayBoundEvents` flag since the code it generates is quite breaking and we never got the chance to enable it. Also it caused our tests to misrepresent how the compiler behaves for actual users.
These changes introduce the new `@Service` decorator which is a more ergonomic alternative to `@Injectable`. The reason we're adding a new decorator is that `@Injectable` has been around since the beginning of Angular and it has a lot of baggage that adds unnecessary overhead for users that generally want to define a singleton service, available in their entire app. The key differences between `@Service` and `@Injectable` are:
1. `@Service` is `providedIn: 'root'` by default. You can opt into providing the service yourself by setting `autoProvided: false` on it.
2. `@Service` doesn't allow constructor-based injection, only the `inject` function.
3. `@Service` doesn't support the complex type signature of `@Injectable` (`useClass`, `useValue` etc.). Instead it supports a single `factory` function.
Example:
```ts
import {Service} from '@angular/core';
import {HttpClient} from '@angular/common/http';
import {AuthService} from './auth';
@Service()
export class PostService {
private readonly httpClient = inject(HttpClient);
private readonly authService = inject(AuthService);
getUserPosts() {
return this.httpClient.get('/api/posts/' + this.authService.userId);
}
}
```
Moves the logic for generating type check blocks into the compiler since it isn't coupled to TypeScript anymore.
Note: the tests haven't been moved over, because they depend on the environment that's currently in `compiler-cli` and it still has some dependencies on TypeScript.
To support the need to resolve symbols without full AST access (e.g. when using virtual files), this commit decouples `ReferenceSymbol` from `ts.ClassDeclaration`.
Changes:
- Updated `ReferenceSymbol.target` to use `SymbolReference` instead of `ts.ClassDeclaration`.
- Removed `getReferenceTargetNode()` from `SymbolDirectiveMeta` and transitioned to `getSymbolReference()`.
- Refactored `getTsSymbolOfReference` in `checker.ts` to handle `SymbolReference` and resolve it to a `ts.Symbol` using a position-optimized AST traversal. This avoids using the private `getTokenAtPosition` API and avoids full file scans by only traversing nodes containing the target position.
