spartacus storefront - Override AuthGuard to require login from a 3rd party

Question

What is the correct/best way of overriding the Spartacus AuthGuard with MsalGuard for example?

Should I just override it like a service or do I need to extend from it and change it?

Answer 1

It depends on the use case, extending makes sense if you want to reuse or build on top of the existing logic, which results in a better upgradability for most of the cases.

But in general, both should work OK, as you will end up with the new class that you'll have to provide as AuthGuard.
