hmm, interesting. I didn't even consider just using the mongoose module. If anything this module could be simplified a lot to just be a simple wrapper around the mongoose module. Right now it duplicates a lot of functionality I think.
From what I can tell from your examples, the main difference is
export const UserModel = getModelForClass(User);
export const UserSchema = buildSchema(User)
and
MongooseModule.forFeature([{ name: User.name, schema: UserSchema }])
from nestjs-typegoose.

@gperdomor I have a problem with your example.
I have this message : " GraphQLError: Type Query must define one or more fields."
ad.ts
import { buildSchema, getModelForClass, prop } from '@typegoose/typegoose';
export class Ad{
@prop({ required: true })
title: String;
@prop({ required: true })
description: String;
}
export const AdModel = getModelForClass(Ad);
export const AdSchema = buildSchema(Ad);ad.controller.ts
import { Body, Controller, Get, Post } from '@nestjs/common';
import { AdsService } from './ads.service';
import { Ad } from './models/ad';
@Controller('ads')
export class AdsController {
constructor(private readonly adService: AdsService) {}
@Get()
async getAds(): Promise<Ad[] | null> {
return await this.adService.findAll();
}
@Post()
async create(@Body() adDto: Partial<Ad>): Promise<Ad> {
return await this.adService.create(adDto);
}
}ad.service.ts
import { Injectable } from '@nestjs/common';
import { InjectModel } from '@nestjs/mongoose';
import { Ad } from './models/ad';
import { ReturnModelType } from '@typegoose/typegoose';
@Injectable()
export class AdsService {
constructor(
@InjectModel(Ad.name)
private readonly adModel: ReturnModelType<typeof Ad>) {}
async create(adDto: Partial<Ad>): Promise <Ad> {
const createdAd = new this.adModel(adDto);
return await createdAd.save();
}
async findAll(): Promise <Ad[]> {
return await this.adModel.find().exec();
}
}ad.module.ts
import { Module } from '@nestjs/common';
import { AdsService } from './ads.service';
import { MongooseModule } from '@nestjs/mongoose';
import { Ad, AdSchema } from './models/ad';
import { AdsController } from './ads.controller';
@Module({
imports:[MongooseModule.forFeature([{ name: Ad.name, schema: AdSchema }])],
controllers: [AdsController],
providers: [AdsService],
})
export class AdsModule {}The error stack trace

@oliviermattei I don't see differences either, but I'm not using graphQL, try without graphQL
