Updates the linkedSignal documentation to specify that it updates its value when the source changes or when any signal referenced in the computation changes, ensuring the description accurately reflects its behavior.
Convert the `TreeVisualizer` to a signal, in the `TreeVisualizerComponent`, to ensure that the router tree render effect is always called; Use explicit `afterNextRender` phases.
There is a bug (?) in all browsers where the timing of the entry change
is delayed when a navigation is initiated by a click on a link via user
interaction. In this case, we need to ensure we do a 'push' navigation
rather than a 'replace'.
Programatically doing element.click() does not reproduce
this behavior, so adding a test for this is difficult (would require
webdriver).
Previously, navigating a `FieldTree` in signal forms involved reactive reads
of the value of the parent field(s), both directly and via `.childrenMap()`.
This meant that on _any_ change to the value of a field, reactive
notifications would trigger updates of computeds, reruns of effects, etc.
So for example, this effect would run on every change to the form:
```ts
const f = form(signal({data: 'abc', unrelated: 0}));
effect(() => {
// accessing f.data incurs a dependency on f().value() which changes
// on every change in the whole form
console.log(f.data().value());
});
```
This is deeply counterintuitive and troublesome when attempting to write
effect logic, and also results in `computed`s unnecessarily updating.
This change introduces the concept of a "reader" computed, which memoizes
the access of a field at a given key via the reactive graph. With this, the
same `f.data` access above now depends on the `data` reader in `f` only,
which is effectively a constant computed. As a result, the effect only
reruns on changes to `data`'s value, as intended.

Previously, several values were being passed into the creation of
`FieldNodeStructure`s that were only used in the creation of child nodes.
Separately, we also passed a `createChildNode` function which these values
were passed back into.
Instead, this moves the small bit of logic from structure.ts behind the
`createChildNode` callback, which reduces the passing of values back-and-
forth and gives `createChildNode` a much more suitable signature.

Move the instructions used to dynamically bind a `Field` directive to a
form control onto the `Field` itself. This way the instructions are only
retained if the app uses the `Field` directive.
PR Close#65599
When registering providers, the DI system assumes that `viewProviders` are registered before plain `providers`. This was reinforced by components always being first in the array of directive matches, only one component being allowed per node and the fact that only components can have `viewProviders`.
This breaks down if there are host directives with `providers` on the component, because they'll execute earlier, throwing off the order of operations.
These changes fix the issue by separating out the resolvers for `viewProviders` and plain `providers` and explicitly running the component's `viewProviders` resolver before any others. This also has the benefit of not attempting to resolve `viewProviders` for directives which are guaranteed not to have them.
Fixes#65724.
Previously, the XSRF interceptor only added the XSRF token to requests with relative URLs.
This commit updates the interceptor to also add the token to requests with absolute URLs, provided they match the current origin.
This commit adds a `.catch()` handler to `transition.finished` from `document.startViewTransition` to prevent unhandled promise rejections. The finished promise can reject with `TimeoutError` or `InvalidStateError` when transitions fail during or after the animation phase.
Based on the Blink source code, the `finished` promise can reject with:
* `TimeoutError`: "Transition was aborted because of timeout in DOM update"
* `InvalidStateError`: "Transition was aborted because of invalid state"
This may happen when the DOM update phase exceeds the browser's internal timeout threshold.
Previously we extracted the regions and only made the visible region visible on the page, but since there is not a need for the
non-visible code to be presented, we don't need to include it in the generated code snippets.
This adds additional tests following the initial implementation in #64737 that cover
the use-case of path parameters before and after the wildcard segment.
Unnecessarily aborting traversal navigations will break focus and scroll
restoration. We need to keep them open rather than replacing them with
an identical router-initiated navigation.
The end of the Router navigation is a block of synchronous logic that
can be compressed into a single operator rather than splitting it across
several, making it harder to step through. The only benefit from the
split is automatic unsubscribe/cancellation, which we can replicate
with an additional 'shouldContinue' check before proceeding.
Currently when the signal debug name transform sees something like `const foo = signal(0);`, it transforms the signal into `signal(0, {...(ngDevMode ? { debugName: 'foo' } : {})})`. After minification this becomes `signal(0, {})` which will allocate memory for the empty object literal.
These changes rework the logic to produce `signal(0, ...(ngDevMode ? [{ debugName: 'foo' }] : []))` which will be fully tree shaken away to `signal(0)`.
In the case that a component injector is destroyed before the animation
queue runs, the animation queue would fail to run because it was using a
destroyed injector. This commit changes the animation queue to run in the
context of the EnvironmentInjector, which is not destroyed until the app
is destroyed.

This is necessary to exclude a race condition where the MutationObserver initialized by the instruction fired before the inputs are binded.
