Versioning

Auto minor versioning

The Publish GitHub Actions workflow auto versions a Pull Requests code with a minor version once it has been merged into the main branch. All you have to do is commit your code and raise a Pull Request and the pipeline will auto version your code for you.

Major or Patch versioning

If you wish to patch or major version your codebase use:

$ npm version <patch|major>

Then:

• Push this code with the auto generated commit to your GitHub Repository
• Raise a Pull Request
• Merge your code into the main branch
• The Publish GitHub Actions workflow will tag and push your major or patch version tags to your GitHub Repository
• The Publish GitHub Actions workflow will release your major or patch versioned code
