Database infrastructure

Here is logics, how ts-multi-tenancy to interact with Postgres through TypeORM.

TIP

We recommend ONLY writing CRUD logics at here.
For example, you can focus on how to manage TypeORM's relations fields, maybe some data post-process, data clean before operate db.

src/infrastructure/user.ts

typescript

// src/infrastructure/user.ts
import { InfrastructureManyModifiable } from '@yunology/ts-multi-tenancy';

import { User } from 'somewhere/you/define/your/model';

export class UserInfrastructure extends InfrastructureManyModifiable<User> {
  private static INSTANCE: UserInfrastructure;

  public static init(): UserInfrastructure {
    if (this.INSTANCE === undefined) {
      this.INSTANCE = new UserInfrastructure();
    }

    return this.INSTANCE;
  }

  public static getInstance(): UserInfrastructure {
    return this.INSTANCE;
  }

  constructor() {
    super(User);
  }

  // ... methods how you operate your database ...
  public getById(
    manager: EntityManager, { tenantId }: RuntimeTenant, id: string,
  ): Promise<User> {
    return this.get(manager, { tenantId, id });
  }
}
