Nice to see the HostTree approach from #16 work for Angular Native too; this helps create a nice platform agnostic boundary to make the fundamental setup in these dev tools even stronger. #199 and #16 both change the same collectors (component tree, injectors, signal graph, NgRx) to walk a HostTree. Whichever one lands second would have to resolve those conflicts and possibly reconcile two versions of the interface. To avoid that, I opened #203 with only the shared base, taken from this PR with your authorship kept:
Browser pages behave the same, nothing is added to the package's exports, and the checks pass on current main. If #203 lands first:
One follow-up idea, here or in a later PR: most of overlay-angular-native.ts is the connection, retry and session code. |
) * refactor(overlay): read the host tree through a HostTree interface The component, injector and NgRx collectors now walk a HostTree (roots, children, parent, tag, connected, isHost, optional selector and anchors) instead of the DOM. domTree() is the default and keeps the shadow DOM walk, ng-container anchors and selectors from main, so a platform without a DOM can run the same collectors over its own views. Extracted from the NativeScript support in #16. Co-authored-by: Nathan Walker <walkerrunpdx@gmail.com> * refactor(overlay): let the signal graph and NgRx overlay take a HostTree The signal graph collector accepts a HostTree as well as a document, so selection by id or selector and the environment graphs work on any tree. installSignalWriteHook moves to signal-history so an overlay can record signal writes without loading the browser overlay, which still re-exports it. attachNgrx takes the tree and a page description in its options, and hostBySelector() finds a host by its selector on any tree. Nothing changes for browser pages: every caller keeps the DOM default. These are the platform-neutral parts of the Angular Native overlay in #199. * fix(overlay): keep the host tree order when walking it Copy the roots and children before reversing them in hostBySelector and the NgRx collector, test both and the signal graph over a HostTree, and list the signal graph among the collectors that walk the host tree. --------- Co-authored-by: Kam <erkamyaman35@gmail.com>
Adds @santoshyadavdev/ng-devtools/overlay-angular-native, which walks Angular Native's engine node tree through a HostTree and reports the component tree, signal graph, injectors and NgRx stores to a devtools server over a WebSocket, reconnecting when the server restarts. Highlight outlines the view through its inline style. The signal graph collector now accepts a HostTree as well as a document. Refs santoshyadavdev#198
Angular Native pages now report their platform, so the panel opens an Angular Native view with Components, Signals, Injectors and Store for the connected app, and an empty state with the setup link when none is connected. The CLI prints the view's URL, list-pages shows each page's platform, and browser-only controls are hidden for Angular Native pages. Adds examples/angular-native, kept outside the pnpm workspace because it installs the package from a local tarball. Refs santoshyadavdev#198
Rebuilds extension/ui for the Angular Native view and the hidden browser-only controls.
The example's todo rows had a checkbox role but no checked state, so screen readers could not tell done items apart. The CLI page now says the tabs show the source scan when no app is connected, and that an Angular Native app connects through the printed URL.
The Angular Native overlay left a global location pointing at the devtools server, so Expo built split bundle URLs from it and lazy routes were fetched from the devtools port, leaving a white screen. The overlay now adds location only while it connects and removes it after, and never replaces an app's own. The pipes collector can also scan a HostTree, so the Angular Native view gets a Pipes tab with live pipes.
Rebuilds extension/ui for the Angular Native Pipes tab.
…is pending The temporary location and navigator were tracked per call, so when two connections overlapped the first to finish removed them while the second was still connecting. They are now shared: added when the first connection starts and removed only after the last one ends, and only if they are still the overlay's own objects.

Adds an overlay for Angular Native apps (Angular on React Native's Fabric, no DOM), so the devtools can inspect them like a browser app.
What changed
HostTreeinterface (roots, children, parent, tag, connected) instead of the DOM.domTree()is the default and keeps the current browser behaviour.@santoshyadavdev/ng-devtools/overlay-angular-nativeexportsinitAngularNativeOverlay({ root: app.engine.root, baseURL }). It walks Angular Native's engine node tree and reports the component tree, signal graph, injectors and NgRx stores to a devtools server over a WebSocket, reconnecting with the same page id when the connection drops. Highlight outlines the native view and puts it back when cleared.platform: 'angular-native'. The panel's Angular Native view (?view=angular-native, and a dock in a hub) shows Components, Signals, Injectors and Store for the connected app, and a setup notice when none is connected.
