SYNOPSIS

npm publish <tarball> [--tag <tag>]
npm publish <folder> [--tag <tag>]

DESCRIPTION

Publishes a package to the registry so that it can be installed by name.

•

<folder>: A folder containing a package.json file

•

<tarball>: A url or file path to a gzipped tar archive containing a single folder with a package.json file inside.

•

[--tag <tag>] Registers the published package with the given tag, such that npm install <name>@<tag> will install this version. By default, npm publish updates and npm install installs the latest tag.

Fails if the package name and version combination already exists in the registry.

npm help Once a package is published with a given name and version, that specific name and version combination can never be used again, even if it is removed with npm-unpublish.
