A package of Ts.ED framework. See website: https://tsed.io/tutorials/typeorm

Feature

Currently, @tsed/typeorm allows you:

• Configure one or more TypeORM connections via the @Configuration decorator. All databases will be initialized when the server starts during the server's OnInit phase.
• Use the Entity TypeORM as Model for Controllers, AJV Validation and Swagger.

Installation

To begin, install the TypeORM module for TS.ED:

npm install --save @tsed/typeorm
npm install --save typeorm

Then import @tsed/typeorm in your Server:

import {Configuration} from "@tsed/common";
import "@tsed/typeorm"; // import typeorm ts.ed module

@Configuration({
   typeorm: [
    {
      name: 'default',
      type: 'postgres',
      ...,

       entities: [
         `./entity/*{.ts,.js}`
       ],
       migrations: [
        `./migrations/*{.ts,.js}`
       ],
       subscribers: [
        `./subscriber/*{.ts,.js}`
       ]
    },
    {
       name: 'mongo',
       type: 'mongodb',
       ...
    }
  ]
})
export class Server {

}

TypeORMService

TypeORMService let you to retrieve an instance of TypeORM Connection.

import {Service, AfterRoutesInit} from "@tsed/common";
import {TypeORMService} from "@tsed/typeorm";
import {Connection} from "typeorm";

@Service()
export class UsersService implements AfterRoutesInit {
    private connection: Connection;
    constructor(private typeORMService: TypeORMService) {

    }

    $afterRoutesInit() {
        this.connection = this.typeORMService.get("db1");
    }

    async create(user: User): Promise<User> {

        // do something
        ...
        // Then save
        await this.connection.manager.save(user);
        console.log("Saved a new user with id: " + user.id);

        return user;
    }

    async find(): Promise<User[]> {
        const users = await this.connection.manager.find(User);
        console.log("Loaded users: ", users);

        return users;
    }

}

Use Entity TypeORM with Controller

To begin, we need to define an Entity TypeORM like this and use Ts.ED Decorator to define the JSON Schema.

import {Property, MaxLength, Required} from "@tsed/common";
import {Entity, PrimaryGeneratedColumn, Column} from "typeorm";

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

  @Column()
  @MaxLength(100)
  @Required()
  firstName: string;

  @Column()
  @MaxLength(100)
  @Required()
  lastName: string;

  @Column()
  @Mininum(0)
  @Maximum(100)
  age: number;
}

Now, the model is correctly defined and can be used with a Controller, AJV validation, Swagger and TypeORM.

We can use this model with a Controller like that:

import {Controller, Post, BodyParams} from "@tsed/common";

@Controller("/users")
export class UsersCtrl {
  constructor(private usersService: UsersService) {}

  @Post("/")
  create(@BodyParams() user: User): Promise<User> {
    return this.usersService.create(user);
  }

  @Get("/")
  getList(): Promise<User[]> {
    return this.usersService.find();
  }
}
