Hello Adewale!
If I understood correctly what you are trying to do:
in the module you can import more than one entity:
TypeOrmModule.forFeature([User, OtherOneHere]),
Then in the service you import one repository per Entity
@InjectRepository(User)
private readonly userRepository: Repository<User>,
@InjectRepository(OtherOneHere)
private readonly otherOneHereRepository: Repository<OtherOneHere>,
