Missing REQUEST InjectionToken from @nguniversal/express-engine/tokens replacement package @angular/ssr

[maxfriedmann]

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

@nguniversal/express-engine or @angular/ssr

Is this a regression?

No

Description

After the migration to Angular v17 (in an nx workspace) I am facing the error that the REQUEST InjectionToken cannot be found anymore. Since the @nguniversal/express-engine package got removed I can't find the InjectionToken in e.g. the @angular/ssr package.

How can I access the request object as described here? https://www.npmjs.com/package/@nguniversal/express-engine#using-the-request-and-response

Please provide a link to a minimal reproduction of the bug

Anything else?

I migrated to angular via the Nx workspace migration tool (nx migrate latest & npx nx migrate --run-migrations --create-commits)

[JeanMeche]

Did you get any errors while running the migrations ? The schematics should handle that for you.
It creates a src/express.tokens.ts that contains the token definitions. Do you have it ? (See #26323 which is a closely related issue).

[JoostK]

Nx implements the migrations themselves, and this particular one is present in Nx 17.1.

Since the tokens now have to be provided by user code and the CLI provides a migration to set this up, I am going to close this since Nx was used to update, not the CLI directly.

[maxfriedmann]

You are right @JoostK, manually using the angular CLI works... With nx it will be tackled in nrwl/nx#20162
