Versioning your packages

If you now created a new release, the workflow would fail as it would try to publish version 1.0.0 again to the package registry. You would manually have to set the version number in the package.json file. In this recipe, we will use GitVersion to automate this process.

Getting ready

Switch to a new branch:

$ git switch -c add-gitversion

How to do it…

1. For GitVersion to automatically determine the version of your git workflow, you have to download all references and not just the HEAD branch. We do this by adding the fetch-depth parameter to the checkout action and setting it to 0:

   - uses: actions/checkout@v4
     with:
       fetch-depth: 0

2. Set up GitVersion in a specific version:

   - name: Install GitVersion
     uses: gittools/actions/gitversion/setup@v0.10.2
     with:
       versionSpec: '5.x'

3. Execute GitVersion to determine the version number:

   - name: Determine Version...
