Which @angular/* package(s) are the source of the bug?

Don't known / other

Is this a regression?

Yes

Description

When certain third-party dependencies are used in conjunction with --live-reload=false, the application fails to load in Angular v19:

Uncaught SyntaxError: The requested module '/@vite/client' does not provide an export named 'injectQuery' (at chunk-QRJ2NFPW.js?v=4363c128:1:10)

Removing --live-reload=false from the ng serve command results in the application working again. It also worked in Angular v18 (with --live-reload=false).

I have found this issue with the @arcgis/core dependency.

To replicate:

npm i @arcgis/core

Then in app.component.ts or main.ts, add an import for a file from the library (add a console.log to prevent dependency from being optimized away):

import FeatureLayer from '@arcgis/core/layers/FeatureLayer'

console.log(FeatureLayer)

Then run the app using:

ng serve --live-reload=false --host=127.0.0.1

Repro of this issue with @arcgis/core is available here:
