nestjs-typegoose-next v0.1.4

由于老版本不兼容，这里新起一个项目进行兼容处理，以供后续使用

Since the old version is not compatible, here is a new project for compatibility processing for subsequent use

nestjs-typegoose-next

Description

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

Using Typegoose removes the need for having a Model interface.

Installation

npm install --save nestjs-typegoose-next

or

yarn add nestjs-typegoose-next

Documentation

Here is the full documentation describing all basic and advanced features.

Basic usage

You can checkout the example project for more details.

app.module.ts

import { Module } from "@nestjs/common";
import { TypegooseModule } from "nestjs-typegoose";
import { CatsModule } from "./cat.module.ts";

@Module({
  imports: [
    TypegooseModule.forRoot("mongodb://localhost:27017/nest", {
      useNewUrlParser: true,
    }),
    CatsModule,
  ],
})
export class ApplicationModule {}

Create class that describes your schema

cat.model.ts

import { prop } from "@typegoose/typegoose";
import { IsString } from "class-validator";

export class Cat {
  @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 { CatsController } from "./cats.controller";
import { CatsService } from "./cats.service";

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

Get the cat model in a service

cats.service.ts

import { Injectable } from "@nestjs/common";
import { InjectModel } from "nestjs-typegoose";
import { Cat } from "./cat.model";
import { ReturnModelType } from "@typegoose/typegoose";

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

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

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

Finally, use the service in a controller!

cats.controller.ts

import { Controller, Get, Post, Body } from "@nestjs/common";
import { CatsService } from "./cats.service";
import { Cat } from "./cats.model.ts";

@Controller("cats")
export class CatsController {
  constructor(private readonly catsService: CatsService) {}

  @Get()
  async getCats(): Promise<Cat[] | null> {
    return await this.catsService.findAll();
  }

  @Post()
  async create(@Body() cat: Cat): Promise<Cat> {
    return await this.catsService.create(cat);
  }
}
