What is the difference between Git Submodules and Git Subtrees?
❓ Interview Prompt: Compare managing external repository dependencies via Git Submodules (pointers) versus Git Subtrees (embedded files).
Submodules link external repositories as lightweight 40-character commit pointers in .gitmodules (requires git submodule update --init). Subtrees merge external repository files directly into the parent commit tree.
Code Implementation Example
bash
git submodule add https://github.com/org/shared-lib.git libs/shared-lib
git submodule update --init --recursive
git subtree add --prefix=libs/shared-lib https://github.com/org/shared-lib.git main --squash💡Adding dependencies using Git Submodules vs Git Subtrees.
🎯 Interview Key Takeaway
Submodules store lightweight commit pointers requiring submodule init; Subtrees embed external file history directly into parent repos.
