GitHub Actions to clean the working directory on self hosted runners

Per the official documentation, self-hosted runners don't need to have a clean instance for every job execution. Your job might however need a clean working directory for every execution.

The goal of this action is to clean the working directory at the beginning or the end of each job.

steps:
  - uses: eviden-actions/clean-self-hosted-runner@v1

To disable the cleanup job (e.g. for debugging purpose), set the environment variable DISABLE_RUNNER_CLEANUP to true

This is an example of a simple NPM build workflow that will clean the working directory after each execution.
