To .gitignore or Not to .gitignore: Should You Include `vendor/` in Your Go Project?

Vendor Folder Management in Go Projects: .gitignore or Not?

Whether to ignore the vendor/ directory in .gitignore is a common debate in Go development.

Reasons for Ignoring vendor/ in .gitignore:

• Avoids reference changes: Vendoring freezes dependency versions, preventing changes in dependencies from disrupting the build.
• Disappearing projects: If a dependency project disappears, having it in vendor/ ensures continued availability.
• Tool evolution: Dependency management tools may evolve over time, and ignoring vendor/ preserves compatibility with future tools.
• Local modifications: If modifications are made to dependencies in the Git repository, they should be tracked.

Reasons for Including vendor/ in .gitignore:

• Clutters the repository: Vendored dependencies can significantly increase repository size.
• Dependency conflicts: Multiple team members working on the same project can lead to dependency conflicts if dependencies are not handled centrally.
• Unnecessary for most projects: For projects that do not require strict dependency management, ignoring vendor/ is unnecessary overhead.

Alternative Solutions:

• Virtual environments: Docker or virtualization can provide isolated development environments with standardized tooling, eliminating the need for individual dependency management.
• Hybrid approach: Keep vendor/ out of version control but provide tools or documentation to generate it.
• Private repository: Maintain a private repository for vendored dependencies, allowing developers to use the same version without including it directly in the main repository.
• Go Modules: Go Modules offer precise dependency versioning and reduce the need for vendoring.
