publish-if-not-published

Publish a package if the current version isn't already published.

Installation

yarn add --dev publish-if-not-published

Usage

Run publish-if-not-published and pass any additional arguments that you would have passed to npm publish.

"$(yarn bin)/publish-if-not-published" -- --otp 123456 --dry-run

Tags

When specifing a non-latest tag to be published, a suffix should also be appended to the version so as not to use up a semver version on a prerelease.

{
  "name": "package",
  "version": "2.0.0-next.0"
}

"$(yarn bin)/publish-if-not-published" -- --tag next

publish-if-not-published checks whether it has been called with a non-latest tag, and the version of the package to prevent:

1. Accidentally publishing a tagged release with a non-suffixed version, or
2. Accidentally publishing a latest release with a suffixed version.

These checks can be turned off with the --no-tag-check flag:

"$(yarn bin)/publish-if-not-published" --no-tag-check -- --tag rc
