I have an API route that returns 100 permutations of a simple picture of a dog. I want to generate those permutations of the dog at build time rather than at runtime to improve performance and reduce the cost of doing this in production when a user requests them.

Can generateStaticParams be used in the app router to do this?

My route is /api/dog/[color]/route.tsx
And I have set dynamic to force-static.

I am running v14 of NextJS. When I build it says the route is static, but the size is 0kbs, so I’m not sure it is working as I would expect it to.
