## Motivation
As Graphcool is being shutdown, we replaced all the graphcool api endpoints with some handcrafted APIs using Prisma & Nexus, that can be found here https://github.com/prisma-labs/nextjs-graphql-api-examples. These GraphQL endpoints are now deployed to Vercel.
## Notes
- I couldn't get the reason-relay example to run. Given that the relay endpoint works on the other relay example, I don't see any reason why it wouldn't work on that one
- The `with-apollo` example is buggy when creating some posts, but nothing related to the switch of the api endpoint as it was already buggy before. I suspect the `concatPagination` strategy to be the cause of that bug, but I couldn't figure it out.
Fixes#14780
