What are the differences between Git submodules and subtrees?

Git submodules are repositories nested inside another Git repository, allowing you to keep them separate. Subtrees, on the other hand, allow you to merge repositories into a single one, making it easier to manage.

When should I use submodules instead of subtrees?

Use submodules when you want to maintain a clear separation between projects and keep their histories intact. Subtrees are better for simpler integration when you want to combine projects into one.

Can you give me an example of when to use each?

Sure! Use submodules for libraries that you want to keep updated independently. Use subtrees for a project where you want to include a library directly in your codebase.

Are there any downsides to using submodules?

Yes, submodules can complicate workflows, especially for new team members. They require additional commands to clone and update, which can lead to confusion.
