What Is Tagging In Version Control?

Tagging is the practice of assigning a label or marker to a specific point in a codebase's history to mark it as significant, usually denoting a particular release, version, or milestone.

Tags are typically used to label stable versions, major releases, or critical points in the project's development. They provide a way to mark important commits or snapshots of the codebase, making it easier to reference and retrieve those specific versions later.

In Git [↗], you can create a tag using the git tag command:

✅ Wrap📋
$ git tag v1.0.0

This command creates a tag named v1.0.0 at the current commit (HEAD). Tags can also be associated with specific commits, making it easier to refer back to those points in the future.

Tags are beneficial for various purposes, including:

1. Release Management: Marking specific versions or releases of the software.
2. Historical Reference: Easy access to important points in the project's history.
3. Collaboration: Facilitating communication among developers by using consistent tags for identified versions.
4. Rollbacks and Hotfixes: Enabling quick identification and reversion to stable versions if needed.

Using tags in version control helps maintain a clear history of the codebase and facilitates collaboration among team members by providing clear references to important states of the project.
