Dapr pub/sub

In this quickstart, you'll create a publisher microservice and a subscriber microservice to demonstrate how Dapr enables a publish-subcribe pattern. The publisher generates messages of a specific topic, while subscribers listen for messages of specific topics.

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 requests click here.

This quickstart includes one publisher:

• Go client message generator checkout

And one subscriber:

• Go subscriber order-processor

Run Go message publisher with Dapr

1. Navigate to the directory and install dependencies:

cd ./checkout
go build app.go

2. Run the Go publisher app with Dapr:

cd ./checkout
dapr run --app-id checkout --app-protocol http --dapr-http-port 3500 --components-path ../../../components -- go run app.go

Run Go message subscriber with Dapr

1. Navigate to the directory and install dependencies:

cd ./order-processor
go build app.go

2. Run the Go subscriber app with Dapr:

cd ./order-processor
dapr run --app-port 6001 --app-id order-processor --app-protocol http --dapr-http-port 3501 --components-path ../../../components -- go run app.go

dapr stop --app-id checkout
dapr stop --app-id order-processor
