Clean Architecture with DDD with Unit of Work Pattern

Domain model with a clean architecture with ports and adapters. It takes into account some tactical patterns from DDD.

Unit of work

return this.uow.runInTransaction(async (tx) => {
  const updatedWh = await this.saveWh.saveWarehouse(warehouse, tx);
  await this.saveReport.save(report, tx);
  return updatedWh;
});

Architecture

Module boundaries

If you have a large monolith that contains many bounded contexts, then the service can be divided into modules by context.

If you have a micro service architecture and you prefer to allocate contexts to different services (which is preferable), then the service can be divided into modules by aggregates.

In this example, there are more than one bounded contexts, you have a monolith in front of you. And this monolith is internally divided into modules according to bounded contexts.
