New service

Check out the greeter example using go-grpc

Import go-grpc

import "github.com/micro/go-grpc"

Create micro.Service

service := grpc.NewService()

Pre-existing Service

What if you want to add grpc to a pre-existing service? Use the build pattern for plugins but swap out the client/server.

Create a plugin file

package main

import (
	"github.com/micro/go-micro/client"
	"github.com/micro/go-micro/server"
	cli "github.com/micro/go-plugins/client/grpc"
	srv "github.com/micro/go-plugins/server/grpc"
)

func init() {
	// set the default client
	client.DefaultClient = cli.NewClient()
	// set the default server
	server.DefaultServer = srv.NewServer()
}

Build the binary

// For local use
go build -i -o service ./main.go ./plugins.go

Run

Because the default client/server have been replaced we can just run as usual

./service
