Publish a package
npm publish <tarball> [--tag <tag>]
npm publish <folder> [--tag <tag>]
Publishes a package to the registry so that it can be installed by name. See
npm-developers(7) for details on what's included in the published package, as
well as details on how the package is built.
By default npm will publish to the public registry. This can be overridden by
specifying a different default registry or using a npm-scope(7) in the name
(see package.json(5)).
<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 specified registry.
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(1).
