Update createEsbuildAngularOptimizePlugin to use the new options object signature for JavaScriptTransformer.transformFile, and update the @angular/build dependency to 22.2.0-next.7.
Prevent Angular DevTools from crashing when elements matching [ng-version] in the DOM do not belong to the host application (such as third-party custom elements or browser extensions). ng.getComponent returns null for these elements, which previously caused ng.getDirectiveMetadata to throw.
`app.component.spec.ts` has been in the tree since the initial DevTools commit
in 2020, but no revision of `shell-browser/src/app/BUILD.bazel` has ever listed
it, and that file has no globs. Two of the three specs in the directory are
wired up; this one has never run.
It could not run as written. The setup declared `AppComponent` and imported
`RouterModule.forRoot([])`, neither of which applies now that the component is
standalone and injects `MessageBus` and `DEEP_LINK_INSTANCE_ID`.
It now stubs the `chrome.devtools` surface that `ngOnInit` reads and covers
both lifecycle hooks: the listeners registered on init, the two performance
track emits, the three guards on the deep link listener, and the listeners
removed on destroy.
Follow-up to #70570, which fixed the same problem in ng-devtools-backend.
`supported-apis.spec.ts` was added in #60585, in a commit that also edited the
`ts_test_library` three lines below the `srcs` it was left out of. No revision
of that BUILD file has ever listed it, so it has not run since March 2025. The
target goes from 12 specs to 14.
Wiring it up alone would not have worked. Every `*IsSupported` helper calls
`ngDebugClient()`, which throws when `window.ng` is undefined, and the old
`expect(supported).toBeTruthy()` set no `ng` at all. It now stubs `ng` and
checks the flag set and that each flag tracks its own debug API.
`ng-debug-api.spec.ts` adds an `[ng-version]` root and did not remove it, which
`getAppRoots()` then picks up in the other file under jasmine's random
ordering, so it now clears the DOM in its own `afterEach`.
`glob` matches the sibling `directive-forest/component-tree` target and keeps
the next spec in this directory from being dropped the same way.
Implement component highlighting on change detection cycles along with embedding
the component-specific data to the directive/component tree explorer.

Use a custom logger that prefixes the messages with `[Angular DevTools]`;
Add ability for dev-only log messages;
Add Angular-DevTools-specific `Error`;
Avoid the leak by unsubscribing from the profiler when the performance track is disabled.
Additionally, drop the duplicated performance track state flag.
We keep getting PRs that target single usages of `hasOwnProperty` and we have ~100 of them. These changes aim to address the issue centrally by swapping out all the instances and adding a lint rule against introducing new ones.
Collapse the section since it takes a significant portion of the vertical space,
whereas most of the times users are exploring the properties leading them to scroll.
Addiotionally, introduce some other minor UI improvements.
Show the missing nav arrows when you select a deeply nested component where
the breadcrumbs path is longer than the container. The nav arrows used to
appear only when the split is resized. Add some other minor improvements.
Before: The View Source button tooltip in signal details static ('View source') even when disabled.
After: The tooltip explains 'Source location is not available for this node' when disabled.
Implements persistent breakpoints for Angular signal consumers (computeds and effects) in Angular DevTools using Chrome DevTools Protocol (CDP).
- Adds debugger permission to Chrome and Firefox extension manifests.
- Implements CDP breakpoint orchestration in background script.
- Updates SignalDetailsComponent and SignalGraphPaneComponent with label icon toggle and persistent state sync across reloads.
- Add info tooltips that describe the visualizations and other
parts of the UI
- Improve the frame selector by adding axes labels and a
horizontal line for frames exceeding 60 fps
- Use a precise frame rate calculations instead of approximations
- Introduce improvements to the details panel
- Improve the bar chart visualization

This fixes a regression introduced by #69309 where the format of `serializedId` from a coma separated string, to a JSON representation of an array.
fixes#70104
Remove the supported 'async-await': false option in esbuild-base.config.mts as Angular DevTools is zoneless and does not require downleveling async/await syntax.
Configure esbuild with supported 'async-await': false in esbuild-base.config.mts so esbuild downlevels async functions and async generators natively.
This allows removing the custom Babel plugin @babel/plugin-transform-async-generator-functions and downlevelAsyncGeneratorsIfPresent option.
`isEditingDirectiveState` used `!this.selectedNode` (a bare signal
reference, always truthy) instead of `!this.selectedNode()`, so the
guard was dead and ArrowDown with no selection threw a TypeError.
Defer the timing hook subscription until the timing API is explicitly enabled. Keep production module loading and development initialization covered by isolated browser test targets.
Extend the Angie illustrations to the empty states that were still plain
text: the injector providers "No such providers" result, the injector tree
unsupported-version notice, the two profiler timeline placeholders, and the
router tree unsupported-version notice.
Adds the magnifying-glass and question poses as assets; the orthos-back
and sad poses are already in the tree.
Conditionally update the browser DevTools tab name to "Angular & Wiz" if the user is identified as a Google employee via internal corp network detection.
Rename Timing API to Performance Track to better reflect the purpose of the actual feature;
Migrate the settings data object to match the new name and drop some redundant keys.
The Angie illustrations on the DevTools empty-state screens (added in
#69786) shipped with an empty `alt` and `aria-hidden="true"`. Give them
descriptive alt text and drop `aria-hidden` to improve accessibility.
The Transfer State and signal-graph tabs render bare-text placeholders
when there's nothing to show. Add the Angie mascot to both, matching the
pattern already shipped on the top-level DevTools screens (#69786):
- Transfer State "isn't using Transfer State" card: replace the
swap_horiz icon with the teaching pose.
- Signal graph "No signals in this component": add the orthos-back pose
above the message.
The DevTools state screens (Angular not detected, unsupported version,
production build) showed a plain Material icon above the message. Show
the Angie mascot instead, matching the treatment already used across
angular.dev (the 404 page, empty search, the preview error state).
Each screen uses a pose that fits its message: the dizzy `error` pose for
"application not detected", `coding-01` for the version-upgrade prompt,
and `sad` for the production build notice.
