Getting started with the Dapr HTTP Service SDK for Go

Mon, 01 Jan 0001 00:00:00 +0000

Prerequisite

Start by importing Dapr Go service/http package:

daprd "github.com/dapr/go-sdk/service/http"

Creating and Starting Service

To create an HTTP Dapr service, first, create a Dapr callback instance with a specific address:

s := daprd.NewService(":8080")

Or with address and an existing http.ServeMux in case you want to combine existing server implementations:

mux := http.NewServeMux()
mux.HandleFunc("/", myOtherHandler)
s := daprd.NewServiceWithMux(":8080", mux)

Once you create a service instance, you can “attach” to that service any number of event, binding, and service invocation logic handlers as shown below. Onces the logic is defined, you are ready to start the service:

Dapr gRPC Service SDK for Go

Prerequisite

Start by importing Dapr Go service/grpc package:

daprd "github.com/dapr/go-sdk/service/grpc"

Creating and Starting Service

To create a gRPC Dapr service, first, create a Dapr callback instance with a specific address:

s, err := daprd.NewService(":50001")
if err != nil {
 log.Fatalf("failed to start the server: %v", err)
}

Or with address and an existing net.Listener in case you want to combine existing server listener:

list, err := net.Listen("tcp", "localhost:0")
if err != nil {
	log.Fatalf("gRPC listener creation failed: %s", err)
}
s := daprd.NewServiceWithListener(list)
