So you have a nice big project that you’ve been working on for a while and you are at a state where you think it will be nice to split a part of the project. This can be to either create it as a library to use it with other projects or just maintain it independantly.
There are two steps involved:
- Splitting out the subpath from the repository and creating a new repository from it.
- Using this new git repository we’ve created in the main repository so that we can continue working.
Let’s tackle them one at a time.
Splitting a subpath into a new repository
I’m assuming that we’re interested in keeping the git history - else, you can simply just copy out the directory into a new folder and init it as a new repository.
-- --all is to ensure that we filter all the branches in the repository.
Next, you simply add new remotes and push your repository there.
Side note: You’ll have to clone the original repository again.
is a new git command that recently was added into git. Using it to create the
new repository is simple enough:
my-api-repo branch consists of just the contents from my-api and all
the relevant commits. This can now be used to push to a new remote:
Merging the subpath back into the original repository
git subtree from earlier for this.
--squash here implies that we just want to create a merge commit - else,
we’ll end up with duplicate commits in the history.
Up Next: Maintaining both the repositories simultaneously.
