> We're working on [`clean-architecture-dotnet`](https://github.com/thangchung/clean-architecture-dotnet) for the new and lightweight version of the minimal Clean Architecture, Domain-driven Design lite, CQRS lite, and just enough Cloud-native patterns, then package into Docker, and finally deploy it using Tye on Kubernetes and Dapr in a practical way 👍

# Dapr building blocks

## Service to service

- Dapr client to calling to another service (`product-catalog-api` to `inventory-api`)
- HTTP/gRPC invocation

## State store

- Using state management to store the shopping cart data and its items
- Redis for state management

## Pub/sub message

- Create, update and delete a project at `product-catalog-api`, and subsequently publish an event to `inventory-api` to create `price`, `rop`, and `eoq`
- Redis for pub/sub

## Input/output binding

TODO

## Observability

- Run `tye` command as following

```bash
$ tye run --dtrace zipkin=http://localhost:9411 --logs seq=http://localhost:5340
```

- Log management with Seq dashboard
