  13 <h2 id="synopsis">SYNOPSIS</h2>
  14 <pre><code>npm update [-g] [&lt;name&gt; [&lt;name&gt; ...]]
  15
  16 aliases: up, upgrade
  17 </code></pre><h2 id="description">DESCRIPTION</h2>
  18 <p>This command will update all the packages listed to the latest version
  19 (specified by the <code>tag</code> config), respecting semver.</p>
  20 <p>It will also install missing packages. As with all commands that install
  21 packages, the <code>--dev</code> flag will cause <code>devDependencies</code> to be processed
  22 as well.</p>
  23 <p>If the <code>-g</code> flag is specified, this command will update globally installed
  24 packages.</p>
  25 <p>If no package name is specified, all packages in the specified location (global
  26 or local) will be updated.</p>
  27 <p>As of <code>npm@2.6.1</code>, the <code>npm update</code> will only inspect top-level packages.
  28 Prior versions of <code>npm</code> would also recursively inspect all dependencies.
  29 To get the old behavior, use <code>npm --depth 9999 update</code>.</p>
  30 <h2 id="examples">EXAMPLES</h2>
  31 <p>IMPORTANT VERSION NOTE: these examples assume <code>npm@2.6.1</code> or later.  For
  32 older versions of <code>npm</code>, you must specify <code>--depth 0</code> to get the behavior
  33 described below.</p>
  34 <p>For the examples below, assume that the current package is <code>app</code> and it depends
  35 on dependencies, <code>dep1</code> (<code>dep2</code>, .. etc.).  The published versions of <code>dep1</code> are:</p>
  36 <pre><code>{
  37   &quot;dist-tags&quot;: { &quot;latest&quot;: &quot;1.2.2&quot; },
  38   &quot;versions&quot;: [
  39     &quot;1.2.2&quot;,
  40     &quot;1.2.1&quot;,
  41     &quot;1.2.0&quot;,
  42     &quot;1.1.2&quot;,
  43     &quot;1.1.1&quot;,
  44     &quot;1.0.0&quot;,
  45     &quot;0.4.1&quot;,
  46     &quot;0.4.0&quot;,
  47     &quot;0.2.0&quot;
  48   ]
  49 }
  50 </code></pre><h3 id="caret-dependencies">Caret Dependencies</h3>
  51 <p>If <code>app</code>&#39;s <code>package.json</code> contains:</p>
  52 <pre><code>&quot;dependencies&quot;: {
  53   &quot;dep1&quot;: &quot;^1.1.1&quot;
  54 }
  55 </code></pre><p>Then <code>npm update</code> will install <code>dep1@1.2.2</code>, because <code>1.2.2</code> is <code>latest</code> and
  56 <code>1.2.2</code> satisfies <code>^1.1.1</code>.</p>
  57 <h3 id="tilde-dependencies">Tilde Dependencies</h3>
  58 <p>However, if <code>app</code>&#39;s <code>package.json</code> contains:</p>
  59 <pre><code>&quot;dependencies&quot;: {
  60   &quot;dep1&quot;: &quot;~1.1.1&quot;
  61 }
  62 </code></pre><p>In this case, running <code>npm update</code> will install <code>dep1@1.1.2</code>.  Even though the <code>latest</code>
  63 tag points to <code>1.2.2</code>, this version does not satisfy <code>~1.1.1</code>, which is equivalent
  64 to <code>&gt;=1.1.1 &lt;1.2.0</code>.  So the highest-sorting version that satisfies <code>~1.1.1</code> is used,
  65 which is <code>1.1.2</code>.</p>
  66 <h3 id="caret-dependencies-below-1-0-0">Caret Dependencies below 1.0.0</h3>
  67 <p>Suppose <code>app</code> has a caret dependency on a version below <code>1.0.0</code>, for example:</p>
  68 <pre><code>&quot;dependencies&quot;: {
  69   &quot;dep1&quot;: &quot;^0.2.0&quot;
  70 }
  71 </code></pre><p><code>npm update</code> will install <code>dep1@0.2.0</code>, because there are no other
  72 versions which satisfy <code>^0.2.0</code>.</p>
  73 <p>If the dependence were on <code>^0.4.0</code>:</p>
  74 <pre><code>&quot;dependencies&quot;: {
  75   &quot;dep1&quot;: &quot;^0.4.0&quot;
  76 }
  77 </code></pre><p>Then <code>npm update</code> will install <code>dep1@0.4.1</code>, because that is the highest-sorting
  78 version that satisfies <code>^0.4.0</code> (<code>&gt;= 0.4.0 &lt;0.5.0</code>)</p>
  79 <h3 id="recording-updates-with-save-">Recording Updates with <code>--save</code></h3>
  80 <p>When you want to update a package and save the new version as
  81 the minimum required dependency in <code>package.json</code>, you can use
  82 <code>npm update --save</code>.  For example if <code>package.json</code> contains</p>
  83 <pre><code>&quot;dependencies&quot;: {
  84   &quot;dep1&quot;: &quot;^1.1.1&quot;
  85 }
  86 </code></pre><p>Then <code>npm update --save</code> will install <code>dep1@1.2.2</code> (i.e., <code>latest</code>),
  87 and <code>package.json</code> will be modified:</p>
  88 <pre><code>&quot;dependencies&quot;: {
  89   &quot;dep1&quot;: &quot;^1.2.2&quot;
  90 }
  91 </code></pre><p>Note that <code>npm</code> will only write an updated version to <code>package.json</code>
  92 if it installs a new package.</p>
  93 <h3 id="updating-globally-installed-packages">Updating Globally-Installed Packages</h3>
  94 <p><code>npm update -g</code> will apply the <code>update</code> action to each globally installed
  95 package that is <code>outdated</code> -- that is, has a version that is different from
  96 <code>latest</code>.</p>
  97 <p>NOTE: If a package has been upgraded to a version newer than <code>latest</code>, it will
  98 be <em>downgraded</em>.</p>
