Git Submodules
Git Submodules is a feature of the Git version control system that allows you to include and manage external Git repositories as subdirectories within a main Git repository. It enables you to keep a project composed of multiple, independent repositories while maintaining a single parent repository that tracks specific commits of the submodules. This is useful for modular development where you want to reuse code across projects without duplicating it.
Developers should use Git Submodules when they need to incorporate external libraries, frameworks, or shared components into their main project while keeping those dependencies as separate repositories with their own version history. Common use cases include managing third-party dependencies, sharing common code across multiple projects, or working on large, modular applications where different teams maintain separate repositories. It helps avoid code duplication and allows for independent updates to submodules.
