Best Practice to Remove a Git Submodule

When you need to remove a submodule from your Git repository, the most straightforward and recommended approach is to use the git rm command followed by a commit and push to the remote repository.

Step-by-Step Guide

Remove the Submodule: Run the command git rm <path/to/submodule>. This will remove the submodule reference from the superproject and is the preferred method as of Git version 2.17 and above.

Commit the Changes: After the submodule is removed, commit the changes to your local repository with a descriptive message, such as:

git commit -m "Removed submodule at "

Push the Changes: Push the changes to the remote repository to update the submodule reference there as well:

git push origin <branch-name>

Replace <branch-name> with the name of the branch you are working on.

Why This is the Best Practice

The git rm <path/to/submodule> command is the best practice because it is a single, atomic operation that handles the removal of the submodule from the superproject. It is efficient, reduces the chance of errors, and keeps your repository clean and organized.

Always double-check the path to the submodule to ensure you’re removing the correct one.
