• Most actions related to version upgrade do it backwards: when you push a commit with version change in a specific branch a release is created.

• This action does the opposite: when you create a release the specified files will get updated with the new version, so you don't forget to update them.

This comes in handy when working with git workflows such as trunk-base-development or master-only.

With the following example after creating a new release with tag v2.0.1 on branch release, a new commit will appear in that same branch with both package.json and app.yaml updated with the version field to 2.0.1.

name: Upgrade Version
on:
  release:
    types: [published]

jobs:
  upgrade-version:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: pocket-studios/action-update-version@v1
        with:
          files: 'package.json, app.yaml'
          version-regexp: '\d+.\d+.\d+'
          repo-token: ${{ secrets.GITHUB_TOKEN }}

The action will fail if:

• Both repo-token and branch-name are not supplied

• The tag cannot be found by octokit

• The regular expression cannot match the release tag

• You specify a file with unsupported extension

• Supported file extensions: json, yaml and yml. To add one simply submit a PR with a new parser on the main.ts file.

By supplying the repo-token the commit will use the release information: author and branch.

You can change the branch commit target and the commit author if you want.
