How Do Go Modules Handle Private Repositories and Affect the GOPATH?

Go Modules, Private Repositories, and Gopath

Introduction:
Go modules have been introduced to manage dependencies in Go projects. However, when transitioning internal codebases from external dependency managers like dep to Go modules, developers may encounter challenges when dealing with private repositories. This question analyzes the behavior of Go modules in the context of private repositories and their impact on the Gopath.

Dotless Paths and Standard Library:
As mentioned by the OP, dotless paths in Go modules are typically reserved for the standard library. This restriction arises from the intention of Go authors to establish a binding between domain names and projects. However, since internal projects do not utilize go get, this principle does not directly apply in this scenario.

All-or-Nothing Dependency Resolution:
The OP correctly assumes that once Go modules are utilized, all dependencies must adhere to the module system. The Gopath then becomes less critical, serving primarily as a cache for downloaded modules. This shift requires dependencies to be resolved using go get, potentially necessitating the use of private repositories.

Handling Private Repositories:
To incorporate private repositories, developers may consider using a workaround with GITHUB_TOKEN to authorize access to private repositories. Additionally, GOPRIVATE can be employed to specify which repositories should be treated as private. This approach enables seamless dependency resolution for private modules.

Standalone Private Module Development:
If desired, developers can move private modules out of the Gopath and develop them independently. However, this approach may introduce the need for pushing and pulling changes remotely, which the OP intended to avoid.

Conclusion:
While Go modules have the potential to enhance dependency management, understanding their implications for private repositories is crucial. The transition to Go modules entails embracing an all-or-nothing approach, where all dependencies must be resolved through the module system. Employing private repositories necessitates the use of authorization tokens and managing private module availability effectively. However, developers can mitigate the need for constant remote interactions by utilizing GOPROXY to enable offline development.
