Examples
In the GitHub repository you can find a few examples of using the TypeGraphQL Prisma integration:
- Prototyping - the workflow of using the generator that creates TypeGraphQL artifacts from Prisma schema and creating a GraphQL schema with all CRUD operation - https://github.com/MichalLytek/typegraphql-prisma/tree/main/examples/1-prototyping 
- Basic - demonstrating how you can create custom methods or custom fields - https://github.com/MichalLytek/typegraphql-prisma/tree/main/examples/2-basic 
- Picking Actions - demonstrating how you can choose certain Prisma actions to be exposed in the GraphQL schema - https://github.com/MichalLytek/typegraphql-prisma/tree/main/examples/3-picking-actions 
- Nest JS - showcase of combining - typegraphql-prismawith- typegraphql-nestjsto expose TypeGraphQL-Prisma2 artifacts as GraphQL schema using Nest JS- https://github.com/MichalLytek/typegraphql-prisma/tree/main/examples/4-nest-js 
To run some example, simply go to the subdirectory, install the dependencies (npm i) and then start the server (npm start).
Each subdirectory contains a examples.gql file with a predefined GraphQL queries that you can use in GraphQL Playground (http://localhost:4000) and play with them by modifying it's shape and data.
