Nest CRUD controllers and services

@nestjsx/crud has been designed for creating CRUD controllers and services in Nest applications. It can be used with TypeORM repositories for now, but Mongoose and additional functionality will be available soon.

API Methods and Endpoints

Assume you've created some CRUD controller with the route @Controller('cats'). In that case, Nest will create endpoints as follows:

GET /cats

Res Data: array of entities; an empty array
Res Code: 200

GET /cats/:id

Req Params: :id - entity id
Res Data: entity object
Res Code: 200; 400; 404

POST /cats

Req Body: entity object
Res Data: entity object
Res Code: 201; 400

PUT /cats/:id

Req Params: :id - entity id
Req Body: entity object
Res Data: entity object
Res Code: 201; 400; 404

DELETE /cats/:id

Req Params: :id - entity id
Res Data: empty
Res Code: 200; 400; 404

Using with TypeORM

1. Install

npm i @nestjsx/crud typeorm @nestjs/typeorm --save

2. Create TypeORM Entity

import { Entity, PrimaryGeneratedColumn, Column } from 'typeorm';

@Entity()
export class Cat {
  @PrimaryGeneratedColumn() id: number;

  @Column() name: string;
}

3. Create Service

import { CrudTypeOrmService } from '@nestjsx/crud/typeorm';
import { Injectable } from '@nestjs/common';
import { InjectRepository } from '@nestjs/typeorm';
import { Repository } from 'typeorm';
import { Cat } from './cat.entity';

@Injectable()
export class CatsCrudService extends CrudTypeOrmService<Cat> {
  constructor(
    @InjectRepository(Cat) private readonly repository: Repository<Cat>,
  ) {
    super(repository);
  }
}

4. Create Controller

import { CrudController } from '@nestjsx/crud';
import { Controller } from '@nestjs/common';
import { Cat } from './cat.entity';
import { CatsCrudService } from './cats-crud.service';

@Controller('cats')
export class CatsCrudController extends CrudController<Cat> {
  constructor(private readonly catsCrudService: CatsCrudService) {
    super(catsCrudService);
  }
}

5. Connect everything in your Module

import { Module } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';
import { Cat } from './cat.entity';
import { CatsCrudService } from './cats-crud.service';
import { CatsCrudController } from './cats-crud.controller';

@Module({
  imports: [TypeOrmModule.forFeature([Cat])],
  providers: [CatsCrudService],
  controllers: [CatsCrudController],
})
export class CatsModule {}

Tests

npm run test
npm run test:e2e

Roadmap

• CRUD for TypeORM
• CRUD for Mongoose
• Expose as Dynamic Module
• Swagger integration
• Working with relations (extending CRUD)
