GitHub Action for Monorepo Split

Version 2.0 now supports split to GitHub and Gitlab private repositories!

Do you have a monorepo project on GitHub and need split packages to many repositories? Add this GitHub Action to your workflow and let it split your packages on every commit and tag.

How does the Split Result Look Like?

This repository splits tests into symplify/monorepo-split-github-action-test repository.

Not on every commit, but only if contents of /tests/packages/some-package directory changes. Try it yourself - send PR with change in that directory.

Config

Split is basically git push or local directory to remote git repository. This remote repository can be located on GitHub or Gitlab. To be able to do that, it needs GITHUB_TOKEN or GITLAB_TOKEN with write repository access:

env:
    GITHUB_TOKEN: ${{ secrets.ACCESS_TOKEN }}
    # or
    GITLAB_TOKEN: ${{ secrets.GITLAB_TOKEN }}

Make sure to add this access token in "Secrets" of package settings: https://github.com/<organization>/<package>/settings/secrets/actions

Define your GitHub Workflow

            - '*'

env:
    # 1. for Github split
    GITHUB_TOKEN: ${{ secrets.ACCESS_TOKEN }}

    # 2. for Gitlab split
