TypeGraphQL with PrismaSelect from Pal.js

paramDecorator.ts

import { PrismaSelect } from '@paljs/plugins';

export function Fields(): ParameterDecorator {
    return createParamDecorator(({ info }) => {
        const fieldsMap = new PrismaSelect(info).value;
        return fieldsMap;
    });
}


Example usage:
/*

  @TypeGraphQL.Mutation(_returns => User, {
        nullable: true,
    })
    async updateUser(
        @TypeGraphQL.Ctx() ctx: Context,
        @TypeGraphQL.Args() args: UpdateUserArgs,
        @Fields() fields: any,
    ): Promise<User | null> {
        const user = await ctx.prisma.user.findUnique({
            where: {
                ...args.where,
            },
            select: {
                status: true,
            },
        });

        return ctx.prisma.user.update({
            where: args.where,
            data: args.data,
            select: {
                ...fields.select,
            },
        });
    }
