Dapr pub/sub

In this quickstart, there is a publisher microservice checkout and a subscriber microservice order-processor to demonstrate how Dapr enables a publish-subscribe pattern. checkout generates messages and publishes to a specific orders topic, and order-processor subscribers listen for messages of topic orders.

Visit this link for more information about Dapr and Pub-Sub.

Note: This example leverages the Dapr client SDK. If you are looking for the example using only HTTP click here.
