如何在Nest.js代码中使用graphql-type-json标量

npm install --save @nestjs/graphql graphql-type-json

import { Module } from '@nestjs/common';
import { GraphQLModule } from '@nestjs/graphql';
import { GraphQLJSON } from 'graphql-type-json';

@Module({
  imports: [
    GraphQLModule.forRoot({
      autoSchemaFile: true,
      scalarsMap: [{ type: GraphQLJSON, scalar: GraphQLJSON }],
    }),
  ],
})
export class AppModule {}

import { Resolver, Query } from '@nestjs/graphql';
import { GraphQLJSON } from 'graphql-type-json';

@Resolver()
export class MyResolver {
  @Query(() => GraphQLJSON)
  myQuery(): Record<string, any> {
    return { key: 'value' };
  }
}
