<pre><code class="language-bash">npm outdated [&lt;package-spec&gt; ...]
</code></pre>
<h3 id="description">Description</h3>
<p>This command will check the registry to see if any (or, specific) installed
packages are currently outdated.</p>
<p>By default, only the direct dependencies of the root project and direct
dependencies of your configured <em>workspaces</em> are shown.
Use <code>--all</code> to find all outdated meta-dependencies as well.</p>
<p>In the output:</p>
<ul>
<li><code>wanted</code> is the maximum version of the package that satisfies the semver
range specified in <code>package.json</code>. If there's no available semver range
(i.e.  you're running <code>npm outdated --global</code>, or the package isn't
included in <code>package.json</code>), then <code>wanted</code> shows the currently-installed
version.</li>
<li><code>latest</code> is the version of the package tagged as latest in the registry.
Running <code>npm publish</code> with no special configuration will publish the
package with a dist-tag of <code>latest</code>. This may or may not be the maximum
version of the package, or the most-recently published version of the
package, depending on how the package's developer manages the latest
<a href="../commands/npm-dist-tag.html">dist-tag</a>.</li>
<li><code>location</code> is where in the physical tree the package is located.</li>
<li><code>depended by</code> shows which package depends on the displayed dependency</li>
<li><code>package type</code> (when using <code>--long</code> / <code>-l</code>) tells you whether this
package is a <code>dependency</code> or a dev/peer/optional dependency. Packages not
included in <code>package.json</code> are always marked <code>dependencies</code>.</li>
<li><code>homepage</code> (when using <code>--long</code> / <code>-l</code>) is the <code>homepage</code> value contained
in the package's packument</li>
<li>Red means there's a newer version matching your semver requirements, so
you should update now.</li>
<li>Yellow indicates that there's a newer version <em>above</em> your semver
requirements (usually new major, or new 0.x minor) so proceed with
caution.</li>
</ul>
<h3 id="an-example">An example</h3>
<pre><code class="language-bash">$ npm outdated
Package      Current   Wanted   Latest  Location                  Depended by
glob          5.0.15   5.0.15    6.0.1  node_modules/glob         dependent-package-name
nothingness    0.0.3      git      git  node_modules/nothingness  dependent-package-name

once           1.3.2    1.3.3    1.3.3  node_modules/once         dependent-package-name
</code></pre>
<p>With these <code>dependencies</code>:</p>
<pre><code class="language-json">{
  "glob": "^5.0.15",
  "nothingness": "github:othiym23/nothingness#master",
  "npm": "^3.5.1",
  "once": "^1.3.1"
}
</code></pre>
<p>A few things to note:</p>
<ul>
<li><code>glob</code> requires <code>^5</code>, which prevents npm from installing <code>glob@6</code>, which
is outside the semver range.</li>
<li>Git dependencies will always be reinstalled, because of how they're
specified.  The installed committish might satisfy the dependency
specifier (if it's something immutable, like a commit SHA), or it might
not, so <code>npm outdated</code> and <code>npm update</code> have to fetch Git repos to check.
This is why currently doing a reinstall of a Git dependency always forces
a new clone and install.</li>
<li><code>npm@3.5.2</code> is marked as "wanted", but "latest" is <code>npm@3.5.1</code> because
npm uses dist-tags to manage its <code>latest</code> and <code>next</code> release channels.
<code>npm update</code> will install the <em>newest</em> version, but <code>npm install npm</code>
(with no semver range) will install whatever's tagged as <code>latest</code>.</li>
<li><code>once</code> is just plain out of date. Reinstalling <code>node_modules</code> from
scratch or running <code>npm update</code> will bring it up to spec.</li>
</ul>
<h3 id="configuration">Configuration</h3>
<h4 id="all"><code>all</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>When running <code>npm outdated</code> and <code>npm ls</code>, setting <code>--all</code> will show all
outdated or installed packages, rather than only those directly depended
upon by the current project.</p>
<h4 id="json"><code>json</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>Whether or not to output JSON data, rather than the normal output.</p>
<ul>
<li>In <code>npm pkg set</code> it enables parsing set values with JSON.parse() before
saving them to your <code>package.json</code>.</li>
</ul>
<p>Not supported by all npm commands.</p>
<h4 id="long"><code>long</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>Show extended information in <code>ls</code>, <code>search</code>, and <code>help-search</code>.</p>
<h4 id="parseable"><code>parseable</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>Output parseable results from commands that write to standard output. For
<code>npm search</code>, this will be tab-separated table format.</p>
<h4 id="global"><code>global</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>Operates in "global" mode, so that packages are installed into the <code>prefix</code>
folder instead of the current working directory. See
<a href="../configuring-npm/folders.html">folders</a> for more on the differences in behavior.</p>
<ul>
<li>packages are installed into the <code>{prefix}/lib/node_modules</code> folder, instead
of the current working directory.</li>
<li>bin files are linked to <code>{prefix}/bin</code></li>
<li>man pages are linked to <code>{prefix}/share/man</code></li>
</ul>
<h4 id="workspace"><code>workspace</code></h4>
<ul>
<li>Default:</li>
<li>Type: String (can be set multiple times)</li>
</ul>
<p>Enable running a command in the context of the configured workspaces of the
current project while filtering by running only the workspaces defined by
this configuration option.</p>
<p>Valid values for the <code>workspace</code> config are either:</p>
<ul>
<li>Workspace names</li>
<li>Path to a workspace directory</li>
<li>Path to a parent workspace directory (will result in selecting all
workspaces within that folder)</li>
</ul>
<p>When set for the <code>npm init</code> command, this may be set to the folder of a
workspace which does not yet exist, to create the folder and set it up as a
brand new workspace within the project.</p>
<p>This value is not exported to the environment for child processes.</p>
