Angular v19 with no app.config.ts, how to install primeng v19

[reagustin]

Hello, I was reading the getting started docs and found out that the information there does not adapt to the actual structure i got for my application. There is no app.config.ts and the routing is handled as the old style, i tried installing an older version like prime ng v15 lts or v16 lts but it does not allow me to do so. I don't want to force the install, is there any documentation on how to install in angular v19 with the old structure/old routing?

I upgraded from Angular 18 and PrimeNG 17, without using app.config.ts. I placed the theming/style in the app.component.ts. I have a limited StackBlitz example.
