Using prisma_studio to connect to any server
When I successfully use prisma in serverless, it is only natural that I want prisma studio to connect to my server in serverless.
When I searched the internet for "prisma studio remote sqlite", I did not find a suitable solution.
There are others who have the same idea and question: https://community.fly.io/t/expose-sqlite-db-to-external-orm-connections/8300
So I decided to implement it myself, thanks to the simplicity of the API interface used by prisma studio, it took less time than I imagined (maybe an hour?).
