Preserve createUrlTree command semantics, including custom serializer inputs, while keeping the single-leading-slash guarantee at the default serialization boundary.
Expand coverage for command forms, public UrlTree values, secondary outlets, and preserved query parameters and fragments.
Fixes#69700
This allows developers to throw a `RedirectCommand` directly from guards and resolvers to trigger a redirect.
The primary benefit is that we no longer need to pollute the return type of functions that redirect. For example, a deeply nested helper function or a resolver can now simply throw a `RedirectCommand` to short-circuit and redirect, instead of having to return the `UrlTree` or `RedirectCommand` all the way up the call stack.
This aligns with prior art in other modern framework routers (such as Next.js, Remix, and SvelteKit), which commonly use thrown exceptions or special redirect responses to abort execution and trigger immediate redirection.
`getTIcu` and `setTIcu` performed `hasOwnProperty` checks with string
literals (`'currentCaseLViewIndex'` and `'tView'`). Under Closure Compiler
property renaming optimizations, these properties are minified but the
string literals are not, causing property lookups and type discriminations
to fail.
This commit defines closure-safe property constants using
`getClosureSafeProperty` so the property names are renamed consistently.
Treat MathML-namespaced script elements as scripts during template preprocessing. This prevents scripts nested in MathML HTML integration points from surviving template compilation.
Use the host element's namespace-aware local name when checking for script
elements. A prefixed SVG script can expose a qualified tag name such as
"x:script" while its local name remains "script".
Recompute the checked state when a reused radio input receives a new value while the form model remains unchanged.
Handle this case for both reactive forms and signal forms, and add regression tests covering reused radio elements.
Updates the nested selector encapsulation logic so that it skips encapsulating child selectors if the parent contains `::ng-deep`. The reasoning is that `:host ::ng-deep { .foo {} }` should behave as `:host ::ng-deep .foo {}`.
This is a second attempt at scoping nested CSS rules after not being able to land #50693. I took some extra precautions to try and avoid the crash that was happening last time.
`DeferredSymbolTracker.lookupIdentifiersInSourceFile` prunes `ts.isTypeNode`
subtrees so that references appearing exclusively inside type annotations
do not keep static import declarations in the emitted JavaScript.
However, `ts.isTypeNode` returns `true` for `ts.ExpressionWithTypeArguments`,
which TypeScript uses to represent both `extends` and `implements` heritage
clauses. An `extends` clause on a class declaration or class expression is a
value position that survives in the emitted JavaScript output.
Because `isTypeNode` returned `true`, references to base classes imported
alongside deferred dependencies were ignored. As a result, the compiler
erroneously marked the static import statement as deferrable and deleted it
from the emitted JavaScript, leaving the `extends <Base>` clause referencing
an undeclared identifier and causing a runtime `ReferenceError`.
This commit ensures that `ExpressionWithTypeArguments` under a class `extends`
clause is not treated as an erasable type node, preserving the static import
whenever a base class is referenced.
Optional chaining was generating expressions with included an extra pair of parenthesis which changed the semantics of the expression and threw an unexpected error from the optional chain non nullable extended diagnostic.
fixes#70085
Prevent AbortController.abort() from executing during Observable teardown when a FetchBackend HTTP request has already completed successfully or errored.
Previously, FetchBackend unconditionally called abort() upon stream termination. When requests completed normally, calling abort() after delivery caused Chromium-based browsers to mark the resolved request as net::ERR_ABORTED in DevTools due to a race condition, leading to missing response body payloads ("Failed to load response data"). By tracking whether the request has already settled—similar to XhrBackend checking for xhr.readyState !== xhr.DONE—we ensure abort() is only called for unsettled, in-flight requests upon unsubscription.
Fixes#70071
Previously, `parseCookieValue` did not strip enclosing double quotes (`DQUOTE`) from quoted cookie values as specified in RFC 6265 Section 4.1.1. In addition, malformed percent-encoding in cookie values caused an unhandled `URIError` when calling `decodeURIComponent`.
Extract the charset parameter from the Content-Type response header in FetchBackend and pass it to TextDecoder when decoding text and json responses. When no valid charset is provided or supported, gracefully fall back to default utf-8 decoding.
Fixes#70061
Fixes#69785
Add an Angular SSR integration test in platform-server verifying that null input values do not render string attributes like value="null" during server-side rendering, while normal non-empty string values like value="hello" are properly preserved.
A timer wrapper such as a browser extension, policy, or automation harness can block a call and return null instead of a handle. patchTimer then read `.refresh` on that null value and threw synchronously.
Treat a nullish handle as non-refreshable so the patched timer keeps working.
Fixes#70044
Replace synchronous detectChanges calls with zoneless-compatible scheduling and stability waits. Preserve NgComponentOutlet coverage for components declared by NgModules.
After incremental hydration became tree-shakable, application bootstrap could finish before a routed component activated the runtime. The one-time trigger scan was then skipped, leaving routed and nested hydration triggers uninitialized.
Coordinate application bootstrap with runtime activation and initialize once both have occurred.
Fixes#69908
Represent withRequestsMadeViaParent() with an internal delegating backend so the interceptor handler can distinguish delegated clients from independent child configurations.
Report unsupported style property binding values in development mode while preserving existing binding behavior. Unwrap trusted style values before appending unit suffixes and link NG0318 warnings to the corresponding error guide.
- r3_factory: use `in` operator instead of `as any` property probing
in isDelegatedFactoryMetadata / isExpressionFactoryMetadata type guards
- r3_deferred_triggers: narrow assignment to
`DeferredBlockTriggers[typeof name]` instead of `as any`
- defer_resolve_targets / reify: drop unnecessary `as any` on
`op.trigger` — `DeferTriggerBase.kind` is present on all union members
- pipe_creation: replace double `as any` with `as {target?: ir.XrefId}`,
and reuse the already-narrowed `slotHandle` variable for the call
- extractor_merger: replace legacy `<any>console` guards with a proper
`typeof console !== 'undefined'` check
Rely on zoneless test scheduling instead of manually triggering change detection. Keep Signals Forms tests aligned with the async-first testing pattern.
Adds the `isFieldTree` utility that allows users to assert whether a value is a field tree. This is something that has come up on Material recently and will be useful for users as well.
Fixes#69984.
`@HostListener` is not limited to methods — it is equally valid on a property
holding a function, which is the idiomatic way to keep `this` bound:
@HostListener('window:beforeunload', ['$event'])
private onUnload = (event: BeforeUnloadEvent) => {...};
Every existing host-listener compliance case declares the handler as a method,
so the property form was uncovered. This adds a case exercising both a public
and a private function-valued property, one of them with a global (`window:`)
event target, and locks in the emitted chained `ɵɵlistener` calls plus
`ɵɵresolveWindow`.
Verified against all four compliance modes (full, partial/linked,
declaration-only); GOLDEN_PARTIAL.js regenerated via the golden update rule.
Include the XSRF interceptor in the root token factory so the automatically provided HttpClient retains the documented default protection without requiring provideHttpClient().
Normalize value-specific HttpHeaders deletions before filtering. The string overload previously used String#indexOf and removed shorter values contained within the requested deletion value, potentially widening outgoing request metadata.
Preserve delete-all behavior only when no value is supplied, and cover string, array, and empty-string deletion.
Prevent lazy HttpHeaders and HttpParams clones from reusing value arrays owned by a materialized source. Append and value-specific delete operations previously mutated those shared arrays, violating the immutable API contract and allowing request metadata to bleed into later requests.
Share value arrays until an update mutates a specific header or parameter, then copy only that array. Cover the affected append and delete paths with regression tests that materialize the source first.
