npm-version(1) -- Bump a package version
========================================

## SYNOPSIS

    npm version [<newversion> | major | minor | patch | premajor | preminor | prepatch | prerelease]

## DESCRIPTION

Run this in a package directory to bump the version and write the new
data back to the package.json file.

The `newversion` argument should be a valid semver string, *or* a
valid second argument to semver.inc (one of "patch", "minor", "major",
"prepatch", "preminor", "premajor", "prerelease"). In the second case,
the existing version will be incremented by 1 in the specified field.

If run in a git repo, it will also create a version commit and tag, and
fail if the repo is not clean.

If supplied with `--message` (shorthand: `-m`) config option, npm will
use it as a commit message when creating a version commit.  If the
`message` config contains `%s` then that will be replaced with the
resulting version number.  For example:

    npm version patch -m "Upgrade to %s for reasons"

If the `sign-git-tag` config is set, then the tag will be signed using
the `-s` flag to git.  Note that you must have a default GPG key set up
in your git config for this to work properly.  For example:

    $ npm config set sign-git-tag true
    $ npm version patch

    You need a passphrase to unlock the secret key for
