# npm-version

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 `package.json` and, if present, `npm-shrinkwrap.json`.

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. This behavior is controlled by `git-tag-version` (see below), and can be disabled on the command line by running `npm --no-git-tag-version version`

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
    user: "isaacs (http://blog.izs.me/) <i@izs.me>"
    2048-bit RSA key, ID 6C481CF6, created 2010-08-31

    Enter passphrase:

If "preversion", "version", "postversion" in the "scripts" property of the package.json, it will execute by running `npm version`. preversion and version ware executed before bump the package version, postversion was executed after bump the package version. For example to run `npm version` after passed all test:

    "scripts": { "preversion": "npm test" }
