NX Keep A Changelog Action

This action is used with the RxJS Ninja Starter to handle bumping of changelogs using the Keep-A-Changelog format.

This action is opinionated in two ways:

• It works with Nx to handle finding affected libraries
• It does not generate changelogs, instead it's used with manual changelogs using the [Unreleased] token.

When a new version is released, this action runs and updated the [Unreleased] to the version in the package and appends the date in YYYY-MM-DD format

There are some properties that can be passed

steps:
  - name: Bump Changelogs
    use: rxjs-ninja/action-keepachangelog-version@v1
    with:
      # Where the nx mono-repo directory is located
      rootdir: '.'
      # Compares against the remote main branch
      basebranch: 'origin/main'
      # Either 'packages' or 'libs' depending on selected layout
      libfolder: 'packages' 
      # Changelog filename
      filename: 'CHANGELOG.md'
      # Replacement text, can be changed if not in English for example
      replacement: 'Unreleased'
      # Runs all steps except writing the changes
      dryrun: 'false'

All values have a default and all are required except for dryrun.
