What is a Submodule?
A Git submodule is a feature that allows you to nest another repository in a repository. This allows you to manage independent projects in one parent repository.
Adding a Submodule
Let's start by adding a submodule.
First, run the following command in your terminal.
git submodule add <repository>
Here <repository> is the URL of the repository you want to add as a submodule.
For example, if you want to add a repository as a submodule named my-submodule, you would do as follows.
git submodule add https://github.com/user/repo.git my-submodule
With this, the submodule is added and the contents of the repository are cloned under the my-submodule directory.
Initializing and Updating a Submodule
Next, initialize and update the submodule.
For this, execute the following commands in the terminal.
git submodule init
git submodule update
These commands allow you to initialize the submodule and check out the latest commit of the submodule.
Incorporating Changes in a Submodule
It's crucial to incorporate changes in the submodule's repository when there are any.
Run the following command in your terminal.
git submodule update --remote
This will incorporate the latest commit of the submodule into the parent repository.
Conclusion
That's all for the basic usage of Git submodules. Although submodules are an advanced feature of Git and require careful handling, mastering them can greatly improve the efficiency of software development.
In the next post, I will introduce techniques to further utilize submodules, so stay tuned!
Happy coding :)
