A regular GRPC example

Only GRPC main.go

package main

import (
	"log"
	"net"
	"time"
	pingpong "github.com/percybolmer/grpcexample/pingpong"
	"google.golang.org/grpc"
	"google.golang.org/grpc/credentials"
)

func main() {

	// We Generate a TLS grpc API
	apiserver, err := GenerateTLSApi("cert/server.crt", "cert/server.key")
	if err != nil {
		log.Fatal(err)
	}
	// Start listening on a TCP Port
	lis, err := net.Listen("tcp", "127.0.0.1:9990")
	if err != nil {
		log.Fatal(err)
	}
	// We need to tell the code WHAT TO do on each request, ie. The business logic.
	// In GRPC cases, the Server is acutally just an Interface
	// So we need a struct which fulfills the server interface
	// see server.go
	s := &Server{}
	// Register the API server as a PingPong Server
	// The register function is a generated piece by protoc.
	pingpong.RegisterPingPongServer(apiserver, s)
	// Start serving
	log.Fatal(apiserver.Serve(lis))
}
