Example Project - Extend Prisma Schema

This project implements an example of mutating the Prisma Schema to:

  • Set the Prisma Binary Target;
  • Add a multi-column column unique constraint to a list; and
  • Add a NOT NULL relationship field

These show three separate ways of mutating the Prisma Schema see keystone.ts and schema.ts.

Instructions

To run this project, clone the Keystone repository locally, run pnpm install at the root of this repository, then navigate to this directory and run:

shell
pnpm dev

This will start the Admin UI at localhost:3000. You can use the Admin UI to create items in your database.

You can also access a GraphQL Playground at localhost:3000/api/graphql, which allows you to directly run GraphQL queries and mutations.

Congratulations, you're now up and running with Keystone! ๐Ÿš€
