How Can I Use Go Modules to Manage Dependencies in Private Gitlab Repositories While Maintaining Offline Development Capabilities?

Go Modules, Private Repositories, and the Gopath

The journey towards implementing Go modules within an existing codebase can raise several questions. Let's delve into the topic of referencing modules within private Gitlab repositories while ensuring local iteration capability.

Dotless Path Limitations

As per the Go authors, dotless paths (internal dependencies without explicit versions) are restricted to the standard library. This distinction arises from the association between domain names and Go projects.

Modules and the Gopath

When embracing Go modules, it's crucial to recognize that all dependencies must comply with the module system. The Gopath primarily serves as a cache for downloaded modules, leaving its relevance in the context of local development questionable.

Managing Private Repository Dependencies

Integrating private repository dependencies poses unique challenges. While an open issue regarding this aspect exists, potential solutions emerge:

• Accept Remote Dependency: Embrace the dependency and tolerate remote push/pull cycles. Workarounds for internet connectivity issues can be explored.
• Merge into a Single Repository: Consolidate all code into a single Git repository, effectively eliminating the need for external dependencies.

Offline Development Considerations

Russ Cox's blog post on vgo addresses concerns related to offline development. The introduction of $GOPROXY provides a solution, allowing for offline module resolution.

Additional Workarounds

One potential workaround to access private repositories without remote push/pull involves utilizing GITHUB_TOKEN. This approach requires generating a token, exporting the token, and configuring Git to substitute the GitHub token for the repository's URL.
