Split and publish parts of your monorepo to dedicated Git repositories.
npm install @xwp/subtree-packager --save-dev
```js
const { SubtreePackage, ComposerPackage } = require( '@xwp/subtree-packager' );
// Point to a directory that should be split into a standalone package.
const packageToSplit = new ComposerPackage(
'/absolute/path/to/composer/package'
);
// Point the git subtree helpers to the package.
const publishPackage = new SubtreePackage(
'/absolute/path/to/monorepo',
packageToSplit
);
// Create a split branch from the current monorepo branch
// and push it to the package repository. Also push a tag matching
// the version string in composer.json of the package.
publishPackage.tagSubtreeVersion(
'git@github.com:upstream/repository-slug.git'
);
