Option to not initialize DataSource in createDataSourceFactory about typeorm

[kamilmysliwiec]

Can you retrieve a repository of a non-initialized data source? This wasn't doable in previous versions of typeorm (with createConnection), hence the question

[Junikorn]

It seems you can

describe('DataSource', () => {
  it('should allow to retrieve repository before init', () => {
    const ds = new DataSource({
      type: 'postgres',
      host: 'localhost',
      port: 5434,
      username: 'postgres',
      password: 'password',
      database: 'postgres',
      entities: [Code],
    });
    const repository = ds.getRepository(Code);
    expect(repository).toEqual(expect.any(Repository));
  });
});

This test is passing for me
