The sample project

In this chapter, in order to not wrestle too much with the build system, we are going to use a smaller Go project than the AddressBook. This project, however, is designed to represent the minimal project in which a build system is valuable. From there, you should be able to, with a bit more configuration, adapt the builds we create here to your own project.

The sample project will have the following file structure:

.
├─ go.mod
├─ go.sum
├─ main.go
└─ proto
   ├─ test.proto
   └─ v1
      └─ test.proto

Notice that we are nesting proto files in the proto directory and the rest of the application is in the root directory. We decided to nest the proto files by at least one level because in this chapter we want to show how to discover multiple proto files that are stored in multiple levels of the proto directory...
