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 configure that workflow yourself. You can look to the .github/workflows/push.yml file in this project as an example.

• 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 a tag for the new version to GitHub.

You can configure some aspects of merge-release action by passing some environmental variables.

• GITHUB_TOKEN (required)
  • Github token to allow tagging the version.
• NPM_AUTH_TOKEN (required)
  • NPM Auth Token to publish to NPM, read here how to setup it as a secret.
• DEPLOY_DIR
  • The path where the dist package.json is to run npm publish. Defaults to the root dir.
• SRC_PACKAGE_DIR
  • The path where the src package.json is found. Defaults to the root dir.
• NPM_REGISTRY_URL
  • NPM Registry URL to use. defaults to: https://registry.npmjs.org/

merge-release will use npm publish unless you've defined a publish script in your package.json.
