Checkout my Microservice DDD project on GitHub
Check out my experimental project on GitHub in Domain-Driven-Design with implementation of Aggregates + Event Sourcing + CQRS. The A + ES technique is used as an audit tool for modifications in the Domain.
The source of the truth of the data is the Domain Events registered in Kafka and to allow high-performance queries, I created a MongoDB database with the 'last processed state of events'.
There is also a Auth Microservice that provides Bearer Tokens. All of this has been implemented with .NET Core/Standard 2.0 and is Docker ready!
