When should I use Git submodules or subtrees?

Can you explain when to use Git submodules versus subtrees?

Sure! Git submodules are best when you want to include a repository as a subdirectory in your project, keeping it separate. Subtrees, on the other hand, allow you to merge the contents of another repository into your own, making it easier to manage as a single project.

What are the advantages of using submodules?

Submodules keep the history of the external repository intact and allow you to update it independently. This is useful for maintaining a clean project structure.

And what about subtrees? What are their benefits?

Subtrees simplify the workflow by allowing you to treat the external repository as part of your own. You can easily push and pull changes without needing to manage separate repositories.

Are there any downsides to using either of them?

Yes, submodules can be tricky to manage, especially for new users, and require additional commands for updates. Subtrees can lead to a larger repository size since they merge the entire history.
