# dismiss-stale-approvals

A GitHub action to automatically dismiss stale approvals on pull requests.

Unlike the built in GitHub protection, this action will compare the `git range-diff` of the new version against the previous version, and only dismiss approvals if the diff has changed.

## Usage

1. Add the below workflow to your repository's `.github/workflows` directory.

2. Ensure that this GitHub Action is required for pull requests, which will ensure that PRs cannot be merged until the action has run successfully.

You can make the check required with either:

- Branch protection rules ([see here](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-protected-branches/managing-a-branch-protection-rule))

- Rulesets ([see here](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-rulesets/creating-rulesets-for-a-repository))

See the [example repository](https://github.com/withgraphite/dismiss-stale-approvals-example-repo) for a complete example.
