Collection of personal Dapr demos.
Note, some of these demos require latest version of Dapr, Ingress gateway, Observability components, or cluster-local Redis and Mongo services. To create Kubernetes cluster with all these components on AKS, or quickly configure an existing cluster, consider the Dapr Cluster Setup utility.

- Tweet stream - Subscribing to a Twitter even stream and publishing to a pub/sub topic
- State change handler - RethinkDB state changes streamed into topic
- Eventing
- gRPC event subscriber - Subscribing to topic and processing its events using gRPC service
- HTTP event subscriber - Subscribing to topic and processing its events using HTTP service
- Services
- gRPC echo service - gRPC service invocation example
- HTTP echo service - HTTP service invocation example
- Sentiment Scorer - Sentiment scoring serving backed by Azure Cognitive Service
- Integrations
