Prisma Integration

TypeGraphQL provides an integration with Prisma by the typegraphql-prisma package.

It generates the type classes and CRUD resolvers based on the Prisma schema, so we can execute complex queries or mutations that corresponds to the Prisma actions, without having to write any code for that.

Overview

To make use of the prisma integration, first we need to add a new generator to the schema.prisma file:

generator typegraphql {
  provider = "typegraphql-prisma"
}

Then, after running prisma generate we can import the generated resolvers classes and use them to build our schema:

import { resolvers } from "@generated/type-graphql";

const schema = await buildSchema({
  resolvers,
  validate: false,
});

So we will be able to execute a complex query, that talks with the real database, in just a few minutes!

query GetSomeUsers {
  users(where: { email: { contains: "prisma" } }, orderBy: { name: desc }) {
    id
    name
    email
    posts(take: 10, orderBy: { updatedAt: desc }) {
      published
      title
      content
    }
  }
}
