nestjs-typegoose

Description

Injects typegoose models for nest components and controllers. Typegoose equivalant for @nestjs/mongoose.

Using Typegoose removes the need for having an Model interface.

Installation

npm install --save nestjs-typegoose

Basic usage

app.module.ts

import { Module } from '@nestjs/common';
import { TypegooseModule } from 'nestjs-typegoose';

@Module({
  imports: [TypegooseModule.forRoot('mongodb://localhost/nest'), CatsModule],
})
export class ApplicationModule {}

Create class that extends Typegoose

cat.model.ts

import { prop, Typegoose } from 'typegoose';
import { IsString } from 'class-validator';

export class Cat extends Typegoose {
  @IsString()
  @prop({ required: true })
  name: string;
}

Inject Cat for CatsModule

cat.module.ts

import { Module } from '@nestjs/common';
import { TypegooseModule } from 'nestjs-typegoose';
import { Cat } from './cat.model';
import { CatsService } from './cat.service';

@Module({
  imports: [TypegooseModule.forFeature(Cat)],
  providers: [CatsService]
})
export class CatsModule {}

Get the cat model in a service

cats.service.ts

import { Injectable } from '@nestjs/common';
import { InjectModel } from '@nestjs/mongoose';
import { Cat } from './interfaces/cat.interface';
import { CreateCatDto } from './dto/create-cat.dto';
import { CatSchema } from './schemas/cat.schema';
import { ModelType } from 'typegoose';

@Injectable()
export class CatsService {
  constructor(@InjectModel(Cat) private readonly catModel: ModelType<Cat>) {}

  async create(createCatDto: {name: string}): Promise<Cat> {
    const createdCat = new this.catModel(createCatDto);
    return await createdCat.save();
  }

  async findAll(): Promise<Cat[]> {
    return await this.catModel.find().exec();
  }
}
