Backport is a JavaScript GitHub Action to backport a pull request by simply adding a label to it.

It can backport rebased and merged pull requests with a single commit and squashed and merged pull requests. It thus integrates well with Autosquash.

1. 🔌 Add this .github/workflows/backport.yml to your repository.

2. 💬 Let's say you want to backport a pull request on a branch named production.

   Then label it with backport production. (See how to create labels.)

3. ✨ That's it! When the pull request gets merged, it will be backported to the production branch. If the pull request cannot be backported, a comment explaining why will automatically be posted.

Note: multiple backport labels can be added. For example, if a pull request has the labels backport staging and backport production it will be backported to both branches: staging and production.
