CoolStore Website is a containerised microservices application consisting of services based on .NET Core running on Dapr. It demonstrates how to wire up small microservices into a larger application using microservice architectural principals.
This repository based on some of the old libraries. So be careful if you use it in your production environment!!!
We are working on practical-clean-ddd for the new version of building the .NET apps with domain-driven design, clean architecture with Docker, Kubernetes, Tye, and Dapr in a practical way 👍
Read documentation for more information.
The business domain is inspired from CoolStore project by JBoss Demo Central and Red Hat Demo Central.

| Name | Usecase | Apps Participants |
|---|---|---|
| Service-to-service invocation |
- User clicks to the detail product - Populate product information for shopping cart items - Order gets detail information of buyer |
productcatalogapp, inventoryapp, shoppingcartapp, identityapp |
| State management | Items in the shopping cart | shoppingcartapp |
| Publish and subscribe | User clicks checkout button, and the checkout process happens. It triggers the pub/sub flow in the system | shoppingcartapp, saleapp, identityapp |
| Resource bindings | Every 30 seconds and 1 minutes the validation process happens. It will change the status of order from Received to Process and Complete via Cron binding | productcatalogapp, inventoryapp |
| Observability | All apps in the application are injected by daprd so that it's tracked and observed by dapr | identityapp, webapigatewayapp, inventoryapp, productcatalogapp, shoppingcartapp, saleapp, web |
| Secrets | Bind with local secret file to hide password of redis | inventoryapp, productcatalogapp, shoppingcartapp, saleapp |
| Actors | N/A | N/A |
Make sure you have dapr and tye installed on your machine!
$ tye run
Go to http://localhost:8000, and you're able to access to several endpoints whenevever it's ready as below:
- Web App:
http://localhost:3000 - Web Api Gateway:
http://localhost:5000 - Identity Server:
http://localhost:5001
- Start core components
$ tye run tye.slim.yaml
- Start dapr apps locally via dapr cli
$ dapr run --app-port 5001 --app-id identityapp dotnet run -- -p src\Services\Identity\IdentityService\IdentityService.csproj
$ dapr run --app-port 5002 --app-id inventoryapp dotnet run -- -p src\Services\Inventory\InventoryService.Api\InventoryService.Api.csproj
$ dapr run --app-port 5003 --app-id productcatalogapp dotnet run -- -p src\Services\ProductCatalog\ProductCatalogService.Api\ProductCatalogService.Api.csproj
$ dapr run --app-port 5004 --app-id shoppingcartapp dotnet run -- -p src\Services\ShoppingCart\ShoppingCartService.Api\ShoppingCartService.Api.csproj
Now, you can start to develop, debug or explore more about dapr with tye via Coolstore Apps.
