merge-release

GitHub Action for automated npm publishing.

This Action publishes a package to npm. It is meant to be used on every successful merge to master but you'll need to configured that workflow yourself. You can look to the .github/workflows/push.yml file in this project as an example.

Workflow

• Check for the latest version number published to npm.
• Lookup all commits between the git commit that triggered the action and the latest publish.
  • If the package hasn't been published or the prior publish does not include a git hash, we'll only pull the commit data that triggered the action.
• Based on the commit messages, increment the version from the lastest release.
  • If the string "BREAKING CHANGE" is found anywhere in any of the commit messages or descriptions the major version will be incremented.
  • If a commit message begins with the string "feat" then the minor version will be increased. This works for most common commit metadata for feature additions: "feat: new API" and "feature: new API".
  • All other changes will increment the patch version.
• Publish to npm using the configured token.
• Push the bumped npm version in package.json back into the repo.
• Push a tag for the new version to GitHub.
