You can even combine Prisma with TypeGraphQL if you're building a GraphQL server that needs to access a databases. In that case, you'd use Prisma Client inside your TypeGraphQL resolvers to send database queries.
In fact, we are collaborating with the maintainer of TypeGraphQL to build an integration between Prisma and TypeGraphQL that will allow you to leverage information from your Prisma models when building your GraphQL schema! :)
