Workspaces

Go 1.18 introduced workspace support. A workspace lets you manage multiple modules together.

1. Create a workspace.

   $ mkdir workspace
   $ cd workspace
   $ go work init
   

2. Create the myapp module.

   $ mkdir myapp
   $ cd myapp
   $ go mod init example.com/myapp
   

3. Add the myapp module to the workspace.

   $ cd ..
   $ go work use ./myapp
   

   myapp.go

   package main
   
   import "fmt"
   import "example.com/mypkg"
   
   func main() {
       fmt.Println(mypkg.Hello())
   }
   

4. Create the mypkg module.

   $ mkdir mypkg
   $ cd mypkg
   $ go mod init example.com/mypkg
   

5. Add the mypkg module to the workspace.

   $ cd ..
   $ go work use ./mypkg
   

   mypkg.go

   package mypkg
   
   func Hello() string {
       return "Hello world!"
   }
   

6. Run the program.

   $ go run example.com/myapp
   Hello world!
