Angular Model definition and DTO

Hi all,
I'd like to learn from Angular developers which is a common approach for defining the Typescript Model objects.

Since these Models map the server-side DTO objects, which in turn map the Database schema, is there a tool or best practice to keep all these objects in sync ?

As beginner, I'm simply replicating the DTO objects in equivalent typescript *.model.ts files. I think this might not work well at scale.

Thanks!
Francesco
