Reusable workflows

clean-packagejson-branch

See workflow

Delete specic github branch. Mainly used for cleanup branch created by update-packagejson workflow. Action has following limitation to prevent accidental deletion.

1. Branch is NOT default branch.
2. Branch is created & commited by github-actions[bot].

Sample usage

  workflow_dispatch:

jobs:
  cleanup:

    with:
      branch: branch_name_to_delete
