Apache Dubbo for Golang

---

Apache Dubbo is an easy-to-use Web and RPC framework that provides multiple language implementations(Go, Java, Rust, Node.js, Web) for communication, service discovery, traffic management, observability, security, tools, and best practices for building enterprise-ready microservices.

Dubbo-go is the Go implementation of triple protocol(a fully gRPC compatible and HTTP-friendly protocol) and the various features for building microservice architecture designed by Dubbo.

Visit the official website for more information.

Getting started

You can learn how to develop a dubbo-go RPC application step by step in 5 minutes by following our Quick Start demo.

It's as simple as the code shown below, you define a service with Protobuf, provide your own service implementation, register it to a server, and start the server.

func (srv *GreetTripleServer) Greet(ctx context.Context, req *greet.GreetRequest) (*greet.GreetResponse, error) {
	resp := &greet.GreetResponse{Greeting: req.Name}
	return resp, nil
}

func main() {
	srv, _ := server.NewServer(
		server.WithServerProtocol(
			protocol.WithPort(20000),
			protocol.WithTriple(),
		),
	)

	_ := greet.RegisterGreetServiceHandler(srv, &GreetTripleServer{})

	if err := srv.Serve(); err != nil {
		logger.Error(err)
	}
}

After the server is up and running, call your service via cURL:

curl \
    --header "Content-Type: application/json" \
    --data '{"name": "Dubbo"}' \
    http://localhost:20000/greet.GreetService/Greet

Or, you can start a standard dubbo-go client to call the service:

func main() {
	cli, _ := client.NewClient(
		client.WithClientURL("127.0.0.1:20000"),
	)

	svc, _ := greet.NewGreetService(cli)

	resp, _ := svc.Greet(context.Background(), &greet.GreetRequest{Name: "hello world"})
	
	logger.Infof("Greet response: %s", resp.Greeting)
}

See the samples for detailed information on usage. Next, learn how to deploy, monitor and manage the traffic of your dubbo-go application by visiting the official website.
