Replaces the plain "Page Not Found" text with the sad Angie mascot
speaking the message from a speech bubble, for a warmer, more on-brand
not-found page. Copy is unchanged and the "Feeling lucky?" search
results are untouched.
The sad pose is added as an SVG asset (cropped tight to the artwork) under
assets/images/angie/. The mascot is decorative (aria-hidden), and it scales
down to stay beside the bubble on mobile.
The popup service example framed the comparison against a vague
'previously you had to define a dynamic component' workflow and pointed
readers at steps no guide describes. Compare against today's
programmatic rendering approach with createComponent instead, which is
what the accompanying example actually uses, and link to the
programmatic rendering guide.
Also remove the note about excluding the component from compilation,
which no longer applies to standalone components.
Fixes#55148
Several adev states show only plain text today. This brings the Angie
mascot into them for warmer, more on-brand empty states, with no change
to copy or behavior:
- Search dialog: a magnifying-glass Angie on "Start typing to see
results", a questioning Angie on "No results found".
- API reference: a questioning Angie on "No API items found." and on the
package filter's "No results found".
- Deprecated API pages: the back-turned orthos pose in the shared
deprecation warning.
The mascots are decorative (aria-hidden) and sized per placement; the
poses are added as SVG assets under assets/images/angie/.
Also moves the Shiki highlighter init in the jsdoc-transforms spec into a
beforeAll, fixing a flake where the spec failed under randomized test
order.
Add a new section for 'Form State Signals' in the signal forms essential guide. This documents global signals such as dirty(), valid(), invalid(), pending(), and touched() at the form level, as requested in issue #69544.
Fixes#69544
Adds build-time validation to catch broken, stale, or miscased internal documentation links in both JSDoc and markdown, including `/api/` and `/guide/` URLs and their fragments. Updates the documentation pipeline to share the canonical route manifest, ensuring that all references are checked against the current navigation structure.
Transform assumed `.required` functions always take options as the first argument.
This is true for `input` and `model`, but not for `viewChild` and `contentChild`,
which take the same arguments as non-required versions.
Change the code to put options for signal queries in the right position,
causing debugName to be correctly generated for signal queries.
Before SVG hosts could be skipped because the highlighter checked for HTMLElement. A case like <foreignObject appSvgDemo> would not get a proper overlay. The highlighter now works with Element so SVG hosts can be found and measured.
Before Directive only hosts could be skipped because the inspected-page lookup and directive explorer matched component hosts and component ids only. A case like <a routerLink="/todos">Todos</a> could highlight the parent component instead of the anchor, and the RouterLink only tree node could fail to select, highlight, or request an overlay. Id 0 could also miss the highlighted state because the tree treated it as absent. The lookup now stops at the nearest component or directive host, and tree matching accepts component and directive ids using null as the absent state.
Selected overlays could fail to reappear for the same element because unhighlighting removed the overlay but left the selected element cached. selected-element cache is now reused only while its overlay is still connected, and unhighlighting clears the cached element.
Overlay geometry used integer coercion. An SVG or transformed element with a 0.5px bounding box could get a 0px overlay. Overlay positioning now preserves fractional DOMRect values.
Extract the AI tool definition interfaces from the core debug module to the devtools primitives module. This relocates ToolDefinition, ToolGroup, and DevtoolsToolDiscoveryEvent to the primitives folder, exposing them cleanly via "export type" in the devtools entry point, improving module organization and readability.
The completions handler kept a local copy of getTokenAtPosition plus three stale TODO comments noting the duplication, but the function is already exported from server/src/utils.ts (hover.ts and others import it from there). Drop the local copy, import the canonical one, and remove the now-meaningless comments.
`parseQueryParam` and the AngularJS-compat `parseKeyValue` accumulate query params into a plain object and check key presence with `obj.hasOwnProperty`, so a `hasOwnProperty` query key clobbers the method and the next lookup throws `TypeError`. Switch both to `Object.hasOwn`, which can't be shadowed by a query key.
Replaces the `node.keySpan.toString().startsWith('attr.')` string allocation in the `suffixNotSupported` extended template check with an O(1) `node.type === BindingType.Attribute` enum comparison.
The diagnostic message string is also extracted to a module-level constant so it is created once at module load time instead of on every diagnostic emit.
Additionally, this change adds missing test coverage for the `.%` and `.em` suffixes, as well as for a plain `attr.` binding without a style suffix.
Measured with a 100-iteration microbenchmark before and after the change (MacBook Pro 2018, Intel CPU):
```ts
const start = performance.now();
for (let i = 0; i < 100; i++) {
new ExtendedTemplateCheckerImpl(templateTypeChecker, program.getTypeChecker(),
[suffixNotSupportedFactory], {}).getDiagnosticsForComponent(component);
}
console.log((performance.now() - start) / 100, 'ms/iter');
```
Before: `~0.24 ms/iter`
After: `~0.14 ms/iter` (~40% faster)
Extend the interpolated signal extended diagnostic to inspect ternary-bound expressions and report uninvoked signal reads in bound bindings.
```
<div [style.width]="width() ? 1 : width"></div>
```
where the false branch should invoke the signal as `width()`.
On mobile, focusing a long nav item shows a matTooltip that escapes the
drawer, ignores inner scroll, and blocks scrolling while open. Suppress
it on mobile using the existing isMobile helper.
Backdrop clicks on the search dialog were also closing the open mobile nav drawers. Adds an id to `<dialog>` and references it from both navs' `docsClickOutsideIgnore` arrays.
Three small, behavior-neutral cleanups to maybeRemoveStaleArrayFields:
1. Avoid allocating an empty Set when prevData.byTrackingKey is
undefined. new Set(undefined) previously created an unused empty
Set on every call for parents with no tracking keys.
2. Guard the per-element tracking-key check on `oldTracking` being
defined, skipping the isObject/hasOwn check entirely when there's
nothing to track.
3. Replace childValue.hasOwnProperty(identitySymbol) with
Object.hasOwn(childValue, identitySymbol). hasOwnProperty throws
on null-prototype array elements (Object.create(null)), which
would crash computeChildrenMap. Object.hasOwn is null-prototype-safe
and preserves "own property" semantics (does not match inherited
identitySymbol values).
4. Replace `data.byTrackingKey?.delete(id)` with
`data.byTrackingKey!.delete(id)`. The optional chaining was dead:
if oldTracking.size > 0, prevData.byTrackingKey (and therefore
data.byTrackingKey, same Map reference via the spread) is always
defined. The `?.` masked this invariant; `!` documents it and
would surface a runtime error instead of a silent no-op if the
invariant is ever violated.
Verified via performance.mark/measure instrumented directly inside
the function (count=1 call for a single-field edit in both cases).
Total duration dropped from ~0.7ms to ~0.1ms, consistent with the
avoided Set allocation in (1) and (2).
Remove `isIterable` from `util/iterable.ts` and
`newTrustedFunctionForDev` from `util/security/trusted_types.ts`
as they are no longer referenced anywhere in the codebase.
Add an architecture doc tracing how the Angular DevTools panel, background worker, content scripts, and backend connect per tab and relay messages, with diagrams for the topology and boot sequence.
Any custom Signal Form control
[will actually work](https://github.com/angular/angular/issues/69074#issuecomment-4601225278)
in both Reactive and Template-Driven form contexts. However, this is not obvious
from reading the docs. This PR points this out very explicitly in both the
migration and custom control guide for Signal Forms.
One notable advantage of this interoperability behavior is the ability to
migrate existing `ControlValueAccessor` controls without breaking users. I've
pointed this out separately.
Previously, extracting foreign component imports relied on the partial
evaluator and semantic import resolution to locate declaration
references across files. This resolver-based approach is incompatible
with isolated declarations and local compilation, where cross-file type
information and full semantic resolution are unavailable.
Replace the resolver-based foreign import evaluation with a lightweight,
AST-based extraction mechanism (`extractForeignImportsFromAst`). This
allows the compiler to extract foreign component names and raw AST
expressions directly from syntax trees during the analysis phase without
requiring full type checking.
Additionally, simplify the `ForeignComponentMeta` interface by removing
the obsolete reference property and implement granular AST diagnostics
that provide actionable error messages and usage examples when invalid
expressions are passed to `foreignImports`.
Adds a reference page for `NG05200`, thrown by `DomSanitizer` when a value is bound to a `<script>` element without being marked trusted via `bypassSecurityTrustScript`. Covers why Angular rejects script content outright, how to reproduce the error, the escape hatch, and the XSS caveat.
