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.
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.
Enables direct navigation to Angular components from the Chrome Performance panel's flame graph.
This feature integrates Angular DevTools with Chrome's `setOpenResourceHandler` by registering a custom URL scheme (`angular-devtools://component/{instanceId}`).
Closes#63960
The change can be treated as a continuation of #68535.
- Make the table header sticky
- Reduce slightly the table density in order to equalize it with the rest of the UI
- Reduce the font size of the type pills
- Change the position of the filter clear button to match with the rest of the filter inputs
- Add a "No such key" label when there are no data rows as a result of filtering
Improve the name of the public methods of the visualizers by using common terms like "highlighted". This should, hopefully, clear up some ambiguities that came with the term "selected". Additionally, clean up some CSS class names.
This refactoring renames the 'element' (tagName string) property of DevToolsNode to 'tagName' for clarity, as 'element' was ambiguous.
It also restores 'nativeElement' as a flat property (undoing the nesting introduced previously) because there are cases (like control flow blocks) where a tag name is present without an associated DOM node, making nesting inappropriate.
Convert the router details panel in DevTools to use a description list (<dl>) instead of a table. This is semantically more correct for key-value metadata and improves accessibility.
- promote to default-on (remove opt-in setting and gear-menu toggle)
- replace the <pre> value cell with a collapsible JSON tree
- add key filter and column sort (size sorts by raw bytes)
- show an educational empty state when the app has no transfer state
- iterate every root in the directive forest and merge their state
- guard size calculation against undefined and circular references
- register listener once with DestroyRef cleanup; add a loading timeout
- distinguish array/string badge colors via theme-aware tokens
- responsive value cell width; flex-based table scroll
- add a component spec; seed the harness fixture with more demo data
Implement singal graph nodes search for easier navigation within graphs with large sets of nodes. The search provides filtering by node type via `type:<SIGNAL_TYPE>` syntax.
Make the `hydration`` property of `DevToolsNode`` optional as frameworks like Client-Only Wiz don't have the same hydration concept as Angular and will not set one for nodes returned from `getComponentForest`.
The PR addresses a missing step in the clustering phase of the signal graph processing on the DevTools frontend. Cluster-to-cluster relationship were missing from the graph, so the change fixes that.
The Angular DevTools Extension doesn't use the `element` property in Client-Only Wiz apps. Once the new `ng.getComponentForest`` function is implemented, Client-Only Wiz could provide `ComponentTreeNode`s without an `element` property. This change supports that case by making the `element` property optional.
Add an optional injector property to the DevToolsNode and IndexedNode types. Features that require an injector use the injector stored on the node, if it exists, and fall back to getInjectorFromElementNode if it doesn't.
In the context of AOT tests, component with defer blocks no longer throw on instanciation if the component is not overridden (with `overrideComponent`)
Prior to this change, all components with a `@defer` block would throw if `compileComponents` was not invoked.
In none-JIT apps, this change makes `compileComponents()` uneccesary.
Client-Only Wiz doesn't have the concept of a directive. Once the new ng.getComponentForest function is implemented, Client-Only Wiz cowilluld provide `ComponentTreeNode`s without a `directives`` property. This change supports that case by making the `directives` property optional.
The "Log to console" button in the prop-actions-menu component incorrectly logs the entire props object rather than the value of the individual prop with which the button is associated. Passing the `node` to the logValue function fixes the prop lookup logic and logs the appropriate prop value to the console.
Depending on the client app version, either show "OnPush" (pre-v22) or "Eager" (v22+); As part of the change, `APP_DATA` root signal has been introduced along with a minor bug fix related to component metadata displaying.
The default change detection strategy is now OnPush.
BREAKING CHANGE: Component with undefined `changeDetection` property are now `OnPush` by default. Specify `changeDetection: ChangeDetectionStrategy.Eager` to keep the previous behavior.
Utilize the new `ng.getControlFlowBlocks` API by refactoring the existing render tree extraction code; Slighly modify @for loop details view
PR Close#66167
- Handle @for data in tree strategies and view extraction
- Show @for details in the UI and property tab
- Persist @for state and update UI accordingly
PR Close#66167
Implement a context menu and add it to each property in the properties pane in order to optimize the available space by consolidating the action buttons of property items with multiple of them. Property items with a single action will retain their original behavior where the action button is directly available to click right after the displayed value.
Fix browser-specific styles infrastructure. PR #62786 cleans up part of the code, but there are still services that attempt to load these stylesheets on `main`.
The childSignalProp nodes were added to make it easier for users to visualize and understand when signals were being passed between components. Adding the preview for the new nodes makes the data being displayed equivalent to that of other reactive nodes in the signal graph.
Rename `property-tab` and `signals-view` to `property-pane` and `signal-graph-pane`, and their respective children, to property indicate their purpose and role; Move `diffing` to `directive-explorer`
The purpose for this change is to add nodes to the signal graph to make it clear when producer nodes, especially those that aren't consumed in the component being inspected, are passed to child components for consumption.
Due to explicit injector type checks, inspecting nodes that have type !== `environment` but at the same time are rendered in the Environment Injector tree, opening their details used to break the app. This change fixes this.
Previous the router tree was an opt-in feature that required manual enablement in settings.
Now the router tree is enabled by default whenever the application supports it and routes are detected.
