This commit converts the typescript import in api.ts to a type-only import
and updates the plugin factory to utilize standard TypeScript server types.
Internal interfaces and specific service types are replaced with general
types to decouple the factory wrapper from internal implementations.
Refactors the `ɵɵcontrolCreate` and `ɵɵcontrol` instructions to delegate control logic to the forms package via new `ɵngControlCreate` and `ɵngControlUpdate` lifecycle hooks. Previously, the logic for binding form state to native elements and custom controls was hardcoded within `@angular/core`.
**Compiler Changes:**
- Introduces a new compilation phase `specializeControlProperties` (in `control_directives.ts`).
- This phase detects properties named `formField` and specializes them into `ControlCreate` and `Control` IR opcodes.
- These opcodes emit `ɵɵcontrolCreate` and `ɵɵcontrol` instructions, respectively.
**Runtime Changes:**
- `ɵɵcontrolCreate` acts as the creation phase. It locates the control directive and invokes its `ɵngControlCreate` method.
- `ɵɵcontrol` acts as the update phase, and invokes the control directive's `ɵngControlUpdate` method (if present).
- Introduces a `passThroughInput` configuration in `ControlFeature`. This specifies the input name (e.g., `formField`) that triggers the control. If the runtime detects that this input is bound to multiple targets (e.g., the `FormField` directive *and* the host component), the control is flagged as "pass-through". In this state, `ɵngControlCreate` returns a no-op update function, deferring responsibility to the other consumer (e.g., the component managing the field itself).
**Forms Changes:**
- `FormField` directive implements `ɵngControlCreate` and `ɵngControlUpdate`.
- Inside this hook, `FormField` determines the type of control it is attached to (Native, CVA, or Custom Signal Control) and delegates to the appropriate handler (`nativeControlCreate`, `cvaControlCreate`, or `customControlCreate`).
- Consolidates all form binding logic within `@angular/forms/signals`, enabling support for new `FormValueControl` and `FormCheckboxControl` interfaces.
- Reorganizes the codebase by moving `FormField` from `api/` to `directive/` and splitting the binding logic into semantic pieces:
- `control_native.ts`, `control_cva.ts`, and `control_custom.ts` contain the specific handlers for each control type.
- `native.ts` and `select.ts` provide helpers for native element discovery and select-specific synchronization.
- `bindings.ts` manages the tracking and application of property/attribute bindings.
Consolidating the standard schema support into `standard_schema.ts` will
cut down on unnecessary g3 patch changes whenever we change
`validation_errors.ts`.
The standalone build.sh script for the language service is no longer
required as the vscode-ng-language-service repository has been merged
into this monorepo. Local development and testing of the extension
can now be handled via the integrated build system.
When dynamic components are rapidly added and removed with animate.leave and animate.enter, a leave animation might fire before the enter animation could, causing an element to be retained. This fix prevents that from occuring by clearing the enter animations in this case.

This commit updates the @angular/localize ng-add schematic to support
the @angular/build:unit-test builder. It ensures that @angular/localize
is added to the types array in the TypeScript configuration file
associated with the unit-test target. If no tsConfig is specified in
the target options, it defaults to tsconfig.spec.json in the project root.
Deeply nested parentheses in URLs (e.g. `(a/(b/(c...)))`) trigger recursive calls in `UrlParser`, which can lead to a `RangeError: Maximum call stack size exceeded`. While such errors are generally caught by the framework, relying on the runtime's stack limit is unpredictable across different environments and engine states (e.g. varying stack sizes in different browsers or Node.js versions).
The deeply nested parentheses can cause a stack overflow. While such URLs can be valid (e.g., `(a/(b/(c...)))`) and serialize to simple paths (e.g., /a/b/c), excessive nesting is unreasonable and likely malicious or accidental.
Linear paths (e.g. /a/b/c/d) are parsed iteratively and do NOT trigger recursion. Only parentheses trigger recursion.
This commit introduces a recursion depth limit of 50. If parsing exceeds this depth, the router will now throw a specific `UNPARSABLE_URL` error with the message "URL is too deep". This ensures a deterministic failure mode that is easier for applications to handle than a crash or generic RangeError.
The limit of 50 is chosen as it should accommodate any reasonable application URL structure (including complex named outlets) while providing a safe upper bound against abusive payloads.
This is essentially a refactor of the error state:
* Before: RangeError (System says "I'm out of stack memory")
* After: RuntimeError (Validator says "Input is invalid")
This provides:
* Semantic Correctness: The error now correctly blames the input ("URL too deep"), not the environment ("Stack full").
* Cross-Platform Consistency: The limit is the same in Chrome, Firefox, Node, and Deno, regardless of their internal recursion limits.
* Fast Failure: We stop at depth 50 instead of depth ~15,000, saving those cycles (though CPU cost is negligible either way).
"wide" URLs are now theoretically more expensive than "deep" URLs (because deep ones fail fast), but both are well within safe bounds for any reasonable input size.
This updates `RouterLinkActive`, `Router.isActive`, and the standalone
`isActive` function to accept `Partial<IsActiveMatchOptions>` which uses
the current default values as the base (paths and queryParams are
subset, fragment and matrix params are ignored).

This commit refactors the `ts_plugin.ts` implementation to use a new `withFallback` helper function. This helper encapsulates the common logic of delegating requests to either the Angular language service directly (for non-TS files or when `angularOnly` is true) or trying the TypeScript language service first before falling back to the Angular language service.
Don't touch hidden, disabled, or readonly fields on submit, since they
don't contribute to form validity. This also prevents errors from
appearing immediately if they're later made interactive.
Fix#66344
Ensure `submit()` behaves as expected while a form is pending.
- Submission is not blocked by pending validation.
- Submission errors prevent pending validation errors from appearing
after they resolve on the same field.
- Submission errors don't prevent pending validation errors from
appearing after they resolve on subfields.
This updates the language service to use the detected version of angular
core in the given project on load rather than the minimum detected
version in the workspace
Updates the form documentation to link to the API reference for the `form()` function.
Also removes unused `HttpClient` import from the async validation example.
PR Close#66732
Update how dev preview, experimental and deprecated labels are visualized in the API list to avoid ambiguity with the current design on larger screens.
This commit prevents the Router from intercepting reload navigations
in the navigate event listener. This would convert hard page reloads
to SPA navigations.
