Circular Dependency in NestJS

Here I have 2 services that import/inject each other: TransactionsService and FundsService

So to able to use both one service in the other, I have to using forwardRef inject.

export class TransactionsService {
  constructor(
    @Inject(forwardRef(() => FundsService))
    private fundService: FundsService
  ) {}
}

export class FundsService {
  constructor(
    @Inject(forwardRef(() => TransactionsService))
    private transService: TransactionsService
  ) {}
}
