Usage as a proxy

Async microservice

If you have a microservice which does not support rest, but rather just listens to topics and responds to other topics like the example file main.go.

In the main.go provided as an example, we are listening on testing.in while sending the response back to testing.out.

$ go run main.go

Then we can run kafka-sync-proxy as a service using the binary or docker.

$ go install github.com/sarkarshuvojit/kafka-sync-proxy
$ kafka-sync-proxy

Then you can fire requests using a curl similar to the following:

curl --location --request POST 'http://localhost:8420/v1/' \
--header 'Content-Type: application/json' \
--data-raw '{
    "requestTopic": "testing.in",
    "responseTopic": "testing.out",
    "payload": {
        "message": "testing the proxy",
        "nested": {
            "child": {
                "subChild": 42
            }
        }
    },
    "headers": {
        "customAuthHeader": "ggg"
    },
    "brokers": [
        "localhost:29092"
    ]
}'
