Developing a gRPC Server

Developing a gRPC Server

Let’s learn how to develop a gRPC server in Go.

We'll cover the following...

In this lesson, we are going to create a gRPC server based on the api.proto file presented in the previous section. Because gRPC needs external packages, we are going to need a GitHub repository to host the files, which is going to be https://github.com/Educative-Content/grpc.

Code walkthrough: gRPC server functions

The code of gServer.go (located in the server directory) that is related to gRPC (some functions were omitted for brevity) is the following:

Go (1.19.0)
package main
import (
	"context"
	"fmt"
	"math/rand"
	"net"
	"os"
	"time"
	"github.com/Educative-Content/protoapi"
	"google.golang.org/grpc"
	"google.golang.org/grpc/reflection"
)

This program uses math/rand instead of the more secure crypto/rand for generating random numbers because we need a seed value to be able to reproduce random number sequences. ...
