How to get typeorm dataSource object when intialized using the Configuration Options in Server.ts

[243826]

the examples which I saw from typeorm for getting dataSource object were by instantiating the DataSource object... I am looking to benefit from the Configuration option initialization.

Can you be more precise over your needs by given exemple.

Excerpt from Server.ts

@Configuration({
  ...config,
  typeorm: {
    name: "default",
    type: "postgres",
    host: process.env.POSGRESS_HOST || "localhost",
    port: process.env.POSTGRESS_PORT || 5432,
    username: process.env.POSTGRESS_USER || "postgres",
    password: process.env.POSTGRESS_PASSWORD || "postgres",
    database: process.env.POSTGRESS_DB || "tsed",
    synchronize: true,
    logging: true,
    entities: ["${rootDir}/../models/**/*.ts"],
    migrations: ["${rootDir}/../migrations/**/*.ts"],
    subscribers: ["${rootDir}/../subscribers/**/*.ts"],
    poolSize: 4,
  },
 ...

Excerpt from a controller:

@Controller("/users")
@Scope(ProviderScope.SINGLETON)
export class UsersController {

  @Inject("typeorm:datasource")
  dataSource: DataSource;

  // i want this.datasource to be pointing to the datasource defined by typeorm in the configuration
  // but it's undefined or null here. how do i get it?
  @Get()
  async getUser(@QueryParams("email") email: string) {
    return this.dataSource.getRepository(User).findOne({ email });
  }
}
 

The comment above explains the problem I am having.

Your configuration seems to be wrong if you use typeorm v0.3.
Please look the doc:

https://tsed.dev/tutorials/typeorm.html

Datasource configuration lust be defined using the datasource provider creation not from the configuration decorator.
