Exploring Tags in GitHub

In the world of version control systems, GitHub stands out as a prominent platform for collaborative software development. Among its many features, GitHub offers a tagging system that allows users to organize and label their repositories effectively. In this blog post, we will delve into the concept of tags in GitHub, exploring their significance, how to create and manage them, and best practices for utilizing tags in your projects.

Understanding Tags

Tags in GitHub serve as markers or labels that can be applied to specific points in a repository's history. They are commonly used to denote significant milestones, such as releases, versions, or specific commits. Tags provide a convenient way to reference and navigate through different versions of a project, making it easier for collaborators and users to identify and access specific points in the repository's timeline.

Creating Tags

- You can create tags in the direct GitHub Repository UI

​- When you create a tag (ex: v1.0.1), GitHub will create assets from the branch you chose.

​- When you update source code and you want 2 options:

• ​Create a new tag with the next version label (ex: v1.0.2)
• Overwrite the existing tag (ex" v1.0.1)

​If you choose option 2 - Overwrite the existing tag. You will run the following steps in the terminal:

Overwrite the existing tag

1. Make your changes and commit them locally:

git add <your_files>
git commit -m "Update files"

2. Tag your commit with the existing tag name (v1.0.1):

git tag -f v1.0.1

3. Push the tag with force option (-f) to update it on GitHub:

git push -f origin v1.0.1

This will overwrite the existing v1.0.1 tag in your GitHub repository with the latest changes from your local repository.

⚠️ Important: Force pushing can have serious consequences, especially if other collaborators are working with the same repository. Make sure to communicate with your team before force-pushing any changes to avoid conflicts or loss of work.
