How Can I Effectively Use Vendoring in Go 1.6 for Dependency Management?

How to Utilize Vendoring in Go 1.6?

Introduction: As per Go 1.6, the vendoring feature is integrated into the language. This guide elucidates its usage and how to leverage it effectively.

Understanding the Vendor Directory: The vendor directory, located at ./vendor/, becomes the primary source for dependency discovery. When executing go build or go run commands, Go tools prioritize this directory over $GOPATH/src.

Implementation: To utilize vendoring, manually copy dependencies from $GOPATH/src into the ./vendor/ directory. This ensures that the go build/install/run tooling accesses the vendor folder.

Alternative Method: Dependency Management Tools Instead of manual copying, dependency management tools like Godep or Govendor simplify the process. They inspect projects, identify dependencies, and transfer them from $GOPATH/src to the ./vendor/ directory.

Overuse of Dependency Management Tools: While dependency management is crucial for ensuring stability, excessive usage can restrict updates and potential bug fixes. Selective vendor management allows for granular control, isolating specific dependencies while permitting regular updates for others.

Vendor Directory and Granular Control: The vendor directory offers flexibility, enabling developers to selectively include problematic dependencies while keeping the majority of projects in sync with the latest releases via go get.

Conclusion: Vendoring in Go 1.6 simplifies dependency management, but it's essential to strike a balance to avoid excessive dependency locking and ensure project stability.
