"Size" of API routes in NextJS

I love the summary table produced by next build. But I was wondering if there's anyway to get the same type of thing for the api routes. Like how big will the code which is shipped out to a lambda be. I'm asking since the attached output doesn't tell me much, I know there's more JS in there from the dependencies. Prisma supposedly ships a 15MB binary for example (or so I've heard), would there be any way to spot something like that?
