@nativescript/vite: extensionless shared-workspace module requests return 404 #11570
Description
@nativescript/vite 8.0.20 serves a workspace-shared TSX module when its device URL includes .tsx, but returns 404 for the extensionless URL. The HMR client uses extensionless script URLs for reimports, so a successful static import does not establish that the same shared module can be hot-reimported.
Verified with the unpatched production NativeScript HTTP route, Vite 8.3.0 and Node 26.12.0. No Coreframe or Octane plugins, device runtime, or images are involved. This is separate from the graph-identity collision in #11569.
Expected and observed
With a native project at <workspace>/native and a module at <workspace>/shared/src/screen.tsx:
| Request | Actual |
|---|---|
/ns/m/shared/src/screen.tsx |
200 |
/ns/m/shared/src/screen |
404 |
Both should serve the same module. server.fs.allow explicitly includes the workspace. The project and temporary directory use real paths to avoid a symlink/filesystem-allow artifact.
Reproduction
Create these files in an empty directory, run pnpm install, then node workspace-fetch.mjs. The assertion intentionally fails after printing the status pair and writing workspace-fetch-result.json.

}Source finding and requested fix
resolveNsMTransformedModule first tries extension/platform candidates as Vite app URLs. Those URLs do not address shared files outside the Vite root. Its later filesystem-root fallback calls resolveFsAnchoredSpec only with the original, extensionless spec; it does not probe the expanded candidates under the workspace root.
Please resolve the same extension/platform candidates under the project/workspace filesystem roots and preserve Vite filesystem access checks. A local exact-version patch doing that passes a real HTTP regression for native-host, shared-workspace and external-source modules, together with graph/hot-context identity checks. This report does not claim device HMR qualification or an upstream-main runtime test.
