NPM-VERSION(1)

NAME
npm-version - Bump a package version

SYNOPSIS

    npm version [<newversion> | major | minor | patch | premajor | preminor | prepatch | prerelease | from-git]
    'npm [-v | --version]' to print npm version
    'npm view <pkg> version' to view a package's published version
    'npm ls' to inspect current package/dependency versions

DESCRIPTION

Run this in a package directory to bump the version and write the new data back to and, if present, .

The argument should be a valid semver string, a valid second argument to semver.inc https://github.com/npm/node-semver#functions (one of , , , , , , ), or . In the second case, the existing version will be incremented by 1 in the specified field. will try to read the latest git tag, and use that as the new npm version.

If run in a git repo, it will also create a version commit and tag. This behavior is controlled by (see below), and can be disabled on the command line by running . It will fail if the working directory is not clean, unless the or flag is set.

If supplied with or config option, npm will use it as a commit message when creating a version commit. If the config contains then that will be replaced with the resulting version number. For example:

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

If the config is set, then the tag will be signed using the 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 , , or are in the property of the package.json, they will be executed as part of running .

The exact order of execution is as follows:

    1.  Check to make sure the git working directory is clean before we get started. Your scripts may add files to the commit in future steps. This step is skipped if the flag is set.

    2.  Run the script. These scripts have access to the old in package.json. A typical use would be running your full test suite before deploying. Any files you want added to the commit should be explicitly added using .

    3.  Bump in as requested (, , , etc).

    4.  Run the script. These scripts have access to the new in package.json (so they can incorporate it into file headers in generated files for example). Again, scripts should explicitly add generated files to the commit using .

    5.  Commit and tag.

    6.  Run the script. Use it to clean up the file system or automatically push the commit and/or tag.

Take the following example:

    "scripts": {
      "preversion": "npm test",
      "version": "npm run build && git add -A dist",
      "postversion": "git push && git push --tags && rm -rf build/temp"
    }

This runs all your tests, and proceeds only if they pass. Then runs your script, and adds everything in the directory to the commit. After the commit, it pushes the new commit and tag up to the server, and deletes the directory.
