Distributed Services with Go

Implement a gRPC Server

Because the compiler generated a server stub, the job left for us is to write it. To implement a server, you need to build a struct whose methods match the service definition in your protobuf.

Create an internal/server directory tree in the root of your project by running mkdir -p internal/server. Internal packages are magical packages in Go that can only be imported by nearby code. For example, you can import code in /a/b/c/internal/d/e/f by code rooted by /a/b/c, but not code rooted by /a/b/g. In this directory, we’ll implement our server in a file called server.go and a package named server. The first order of business is to define our server type and a factory function to create an instance of the server.
