nestjs-cqrs-starter's Issues

Graphql subscriptions

Really like the efforts you've put into this.

Does this lib support graphql subscriptions? On nestjs docs it says federation does not support subscriptions.

Any ideas how can we achieve subscriptions?

How to replay events?

Hi, first of all, nice repository. I've been studying Event Sourcing in the last couple weeks and this is one of the finest example I've seen so far.

However, I'm wondering, is it possible to replay events?

Let's say that I change the projection structure and want to update my states to fit it, how should I proceed?

Action Required: Fix Renovate Configuration

There is an error with this repository's Renovate configuration that needs to be fixed. As a precaution, Renovate will stop PRs until it is resolved.

Error type: undefined. Note: this is a nested preset so please contact the preset author if you are unable to fix it yourself.

serious problem !

hello,

I encounter this error when executing the project :

[Nest] 22613  - 07/25/2021, 4:34:24 PM     LOG [InstanceLoader] EventStoreModule dependencies initialized +1ms
[Nest] 22613  - 07/25/2021, 4:34:24 PM   ERROR [ExceptionHandler] Nest can't resolve dependencies of the CommandBus (?). Please make sure that the argument ModuleRef at index [0] is available in the CqrsModule context.

Potential solutions:
- If ModuleRef is a provider, is it part of the current CqrsModule?
- If ModuleRef is exported from a separate @Module, is that module imported within CqrsModule?
  @Module({
    imports: [ /* the Module containing ModuleRef */ ]
  })
