Fork of typegraphql-prisma

This project is a fork of another with minor changes, created for personal use.

Long term support is not guaranteed, use of this copy is at your own risk.

Installation

npm install typegraphql-prisma-nestjs --save-dev

Differences from the original project:

Functions and classes used in generated files from scheme of prisma, imports from nestjs

Original:

import { Ctx, Query, Resolver } from "type-graphql";

In fork:

import { Context, Query, Resolver } from "@nestjs/graphql";

Append transformArgsIntoPrismaArgs and setTransformArgsIntoPrismaArgs for modify args before send it to prisma

PR: https://github.com/MichalLytek/typegraphql-prisma/pull/399

Add support mark part of fields as optional

@TypeGraphQL.optional(input: ["create", "update"])

Add support call some async events after request to Prisma

setTransformArgsIntoPrismaArgs(async function <
  TArgs = Record<string, any>,
  TContext = any,
>(
  info: GraphQLResolveInfo,
  args: TArgs,
  ctx: TContext,
  modelName?: string,
  collectionName?: string,
  prismaMethod?: string,
  afterProcessEvents?: ((result: any) => Promise<any>)[],
): Promise<TArgs> {
  // ...some logic before request to prisma
  afterProcessEvents?.push(async function (result) {
    // ...some logic after request to prisma, variable result store output data
  });
  return args;
});

Add options for skip generate methods and fields resolvers

emitActions: 'findUnique, findUniqueOrThrow, findFirst, findFirstOrThrow, findMany, createOne, createMany, createManyAndReturn, updateOne, updateMany, deleteOne, deleteMany, upsertOne, aggregate, groupBy'

emitPropertyMethods: 'create, connectOrCreate, upsert, set, disconnect, delete, connect, update, updateMany, deleteMany'

Feedback

Currently released version 0.x is just a preview of the upcoming integration. For now it lacks some customization option - picking models or fields of object types to expose in the schema, hiding input fields as well as picking exposed args fields. However, the base functionality is working well, so I strongly encourage you to give it a try and play with it.

Any feedback about the developers experience or ideas about new features or enhancements are very welcome - please feel free to put your two cents by using the GitHub Discussions feature:

Security contact information

Future of this project

This project is not sponsored by Prisma anymore, so there will be provided only bug fixes and Prisma compatibility upgrades. You can read more about this in the GitHub issue #385.

Let's keep typegraphql-prisma alive together! 💪
