<p>Set to true to run the command in the context of <strong>all</strong> configured

|

<li>Commands that operate on the <code>node_modules</code> tree (install, update, etc.)

|
other things (test, exec, publish, etc.) will operate on the root project,
|
||
|
|
<em>unless</em> one or more workspaces are specified in the <code>workspace</code> config.</li>
|

<p>Include the workspace root when workspaces are enabled for a command.</p>
|
||
|
|
<p>When false, specifying individual workspaces via the <code>workspace</code> config, or

all workspaces via the <code>workspaces</code> flag, will cause npm to operate only on

the specified workspaces, and not on the root project.</p>

<p>This value is not exported to the environment for child processes.</p>

<h3 id="description">Description</h3>
|
||
|
|
<p>Run this in a package directory to bump the version and write the new data
|
||
|
|
back to <code>package.json</code>, <code>package-lock.json</code>, and, if present,
|
||
|
|
<code>npm-shrinkwrap.json</code>.</p>
|
||
|
|
<p>The <code>newversion</code> argument should be a valid semver string, a valid second
|
||
|
|
argument to <a href="https://github.com/npm/node-semver#functions">semver.inc</a> (one
|
||
|
|
of <code>patch</code>, <code>minor</code>, <code>major</code>, <code>prepatch</code>, <code>preminor</code>, <code>premajor</code>,
|
||
|
|
<code>prerelease</code>), or <code>from-git</code>. In the second case, the existing version will
|
||
|
|
be incremented by 1 in the specified field. <code>from-git</code> will try to read
|
||
|
|
the latest git tag, and use that as the new npm version.</p>
|
||
|
|
<p>If run in a git repo, it will also create a version commit and tag. This
|
||
|
|
behavior is controlled by <code>git-tag-version</code> (see below), and can be
|
||
|
|
disabled on the command line by running <code>npm --no-git-tag-version version</code>.
|
||
|
|
It will fail if the working directory is not clean, unless the <code>-f</code> or
|
||
|
|
<code>--force</code> flag is set.</p>
|
||
|
|
<p>If supplied with <code>-m</code> or <a href="../using-npm/config#message.html"><code>--message</code> config</a> option,
|
||
|
|
npm will use it as a commit message when creating a version commit. If the
|
||
|
|
<code>message</code> config contains <code>%s</code> then that will be replaced with the resulting
|
||
|
|
version number. For example:</p>
|
||
|
|
<pre><code class="language-bash">npm version patch -m "Upgrade to %s for reasons"
|
||
|
|
</code></pre>
|
||
|
|
<p>If the <a href="../using-npm/config#sign-git-tag.html"><code>sign-git-tag</code> config</a> is set, then the
|
||
|
|
tag will be signed using the <code>-s</code> 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:</p>
|
||
|
|
<pre><code class="language-bash">$ 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:
|
||
|
|
</code></pre>
|
||
|
|
<p>If <code>preversion</code>, <code>version</code>, or <code>postversion</code> are in the <code>scripts</code> property
|
||
|
|
of the package.json, they will be executed as part of running <code>npm version</code>.</p>
|
||
|
|
<p>The exact order of execution is as follows:</p>
|
||
|
|
<ol>
|
||
|
|
<li>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 <code>--force</code> flag is set.</li>
|
||
|
|
<li>Run the <code>preversion</code> script. These scripts have access to the old
|
||
|
|
<code>version</code> 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 <code>git add</code>.</li>
|
||
|
|
<li>Bump <code>version</code> in <code>package.json</code> as requested (<code>patch</code>, <code>minor</code>,
|
||
|
|
<code>major</code>, etc).</li>
|
||
|
|
<li>Run the <code>version</code> script. These scripts have access to the new <code>version</code>
|
||
|
|
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 <code>git add</code>.</li>
|
||
|
|
<li>Commit and tag.</li>
|
||
|
|
<li>Run the <code>postversion</code> script. Use it to clean up the file system or
|
||
|
|
automatically push the commit and/or tag.</li>
|
||
|
|
</ol>
|
||
|
|
<p>Take the following example:</p>
|
||
|
|
<pre><code class="language-json">{
|
||
|
|
"scripts": {
|
||
|
|
"preversion": "npm test",
|
||
|
|
"version": "npm run build && git add -A dist",
|
||
|
|
"postversion": "git push && git push --tags && rm -rf build/temp"
|
||
|
|
}
|
||
|
|
}
|
||
|
|
</code></pre>
|
||
|
|
<p>This runs all your tests and proceeds only if they pass. Then runs your
|
||
|
|
<code>build</code> script, and adds everything in the <code>dist</code> directory to the commit.
|
||
|
|
After the commit, it pushes the new commit and tag up to the server, and
|
||
|
|
deletes the <code>build/temp</code> directory.</p>
