go mod子目录结构

I'm using the following struct on my project, but it feels hacky

App
├── go.mod
├── app.go
└── src
    └── foo
    |    └── foo.go
    └── bar
        └── bar.go

Is there a way to organize it like that?

App
├── go.mod
└── src
    ├── app.go
    └── foo
    |    └── foo.go
    └── bar
        └── bar.go

You could just move the app.go file into the src directory.

However, it's generally ill-advised to have an src folder in a Go project. I recommend you take a look here for recommendations re: project structure.

I like the following structure

App
├── makefile
├── go.mod
├── httpd <- Entrypoint is here - CLI or Http Server
|   └── main.go
└── platform <- Project specific dependencies that are not shared between projects

e.g

App
├── makefile
├── go.mod
├── httpd
|   └── handlers
|   |    └── hello-world_get.go
|   |    └── hello-world_get_test.go
|   └── main.go
└── platform
    └── user
        └── user.go
        └── user_test.go
