GraphQL Code Generation

This project uses GraphQL Code Generator to generate TypeScript types and resolvers from your GraphQL schema.

1. Update the GraphQL Schema

Edit schema.graphql as needed.

2. Generate Types

npm run codegen

This will generate types in src/generated/graphql.ts.

Using Prisma Client

You can use the generated Prisma Client in your services. Example:

import { PrismaService } from '../prisma.service';

@Injectable()
export class ExampleService {
  constructor(private prisma: PrismaService) {}

  async getAuthors() {
    return this.prisma.author.findMany();
  }
}
