Git submodule

The recent use of this command, mainly in order to implement in a git warehouse, the introduction of other Git warehouse, this applies to you want to introduce other libraries in the main project, the main project in the form of submodule, the subproject can have their own git operations, such as commit, Push, rebase and so on.

Here I use a practical example to introduce the use of this command, do not know if everyone has been embedded in the original project react Native. The alumni who are familiar with the react native project know that there is an Android project, as shown below:

You will find that there will be an iOS project, our client development will generally maintain a git warehouse, in order to allow Android and iOS are not the same project commit, mainly for the convenience of maintenance, so I think how to introduce in the RN Project Android and iOS project , understand our needs, we know that there are submodule in git, so go straight to the bottom. Add Submodule Engineering

Git submodule add http://git.code.oa.com/TCW/Crowdsource-android.git android

After executing this command, you can see the change information through git status:

On Branch master
Your Branch are up-to-date with ' origin/master '.
Changes to is committed:
  (use "git Reset head <file> ..." to unstage)

    new file:   . gitmodules
    New File :   Android

Then add the child modules:

git Add. getmodules android
git commit-m "add Android submodule."
Git submodule init

OK, here you have successfully added a submodule. Modify Submodule

Into the submodule.

CD Android

My submodule here is Android.

When I changed the contents of the Android project, git status:

Submit Submodule content to remote:

git Add.
git commit-m "embed react Native"
git push

After submitting, look at the submodule changes in the main project:

CD..
git status

The following figure:

At this point, the changes to the main project are submitted:

git Add.
git commit-m "update android submodule"
git push

OK, the submodule has been successfully modified here. Update Submodule

Here is a problem, you completed the submodule in your own machine to add and modify, that other students want to update how to do.

Run the following command in the main project root directory:

Git submodule foreach git pull

You also need to update the following submodule:

cd Android
git pull

Ok so that other team members will be able to pull up the latest engineering code. Summary

about how to introduce the Android project through Submodule in the RN project has been basically done, and the clone submodule and remove submodule operations will not be demonstrated, you can refer to the links provided below. More References
