+<h2 id="synopsis">SYNOPSIS</h2>
+<pre><code>npm update [-g] [<name> [<name> ...]]
+
+aliases: up, upgrade
+</code></pre><h2 id="description">DESCRIPTION</h2>
+<p>This command will update all the packages listed to the latest version
+(specified by the <code>tag</code> config), respecting semver.</p>
+<p>It will also install missing packages. As with all commands that install
+packages, the <code>--dev</code> flag will cause <code>devDependencies</code> to be processed
+as well.</p>
+<p>If the <code>-g</code> flag is specified, this command will update globally installed
+packages.</p>
+<p>If no package name is specified, all packages in the specified location (global
+or local) will be updated.</p>
+<p>As of <code>npm@2.6.1</code>, the <code>npm update</code> will only inspect top-level packages.
+Prior versions of <code>npm</code> would also recursively inspect all dependencies.
+To get the old behavior, use <code>npm --depth 9999 update</code>.</p>
+<h2 id="examples">EXAMPLES</h2>
+<p>IMPORTANT VERSION NOTE: these examples assume <code>npm@2.6.1</code> or later. For
+older versions of <code>npm</code>, you must specify <code>--depth 0</code> to get the behavior
+described below.</p>
+<p>For the examples below, assume that the current package is <code>app</code> and it depends
+on dependencies, <code>dep1</code> (<code>dep2</code>, .. etc.). The published versions of <code>dep1</code> are:</p>
+<pre><code>{
+ "dist-tags": { "latest": "1.2.2" },
+ "versions": [
+ "1.2.2",
+ "1.2.1",
+ "1.2.0",
+ "1.1.2",
+ "1.1.1",
+ "1.0.0",
+ "0.4.1",
+ "0.4.0",
+ "0.2.0"
+ ]
+}
+</code></pre><h3 id="caret-dependencies">Caret Dependencies</h3>
+<p>If <code>app</code>'s <code>package.json</code> contains:</p>
+<pre><code>"dependencies": {
+ "dep1": "^1.1.1"
+}
+</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
+<code>1.2.2</code> satisfies <code>^1.1.1</code>.</p>
+<h3 id="tilde-dependencies">Tilde Dependencies</h3>
+<p>However, if <code>app</code>'s <code>package.json</code> contains:</p>
+<pre><code>"dependencies": {
+ "dep1": "~1.1.1"
+}
+</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>
+tag points to <code>1.2.2</code>, this version does not satisfy <code>~1.1.1</code>, which is equivalent
+to <code>>=1.1.1 <1.2.0</code>. So the highest-sorting version that satisfies <code>~1.1.1</code> is used,
+which is <code>1.1.2</code>.</p>
+<h3 id="caret-dependencies-below-1-0-0">Caret Dependencies below 1.0.0</h3>
+<p>Suppose <code>app</code> has a caret dependency on a version below <code>1.0.0</code>, for example:</p>
+<pre><code>"dependencies": {
+ "dep1": "^0.2.0"
+}
+</code></pre><p><code>npm update</code> will install <code>dep1@0.2.0</code>, because there are no other
+versions which satisfy <code>^0.2.0</code>.</p>
+<p>If the dependence were on <code>^0.4.0</code>:</p>
+<pre><code>"dependencies": {
+ "dep1": "^0.4.0"
+}
+</code></pre><p>Then <code>npm update</code> will install <code>dep1@0.4.1</code>, because that is the highest-sorting
+version that satisfies <code>^0.4.0</code> (<code>>= 0.4.0 <0.5.0</code>)</p>
+<h3 id="recording-updates-with-save-">Recording Updates with <code>--save</code></h3>
+<p>When you want to update a package and save the new version as
+the minimum required dependency in <code>package.json</code>, you can use
+<code>npm update --save</code>. For example if <code>package.json</code> contains</p>
+<pre><code>"dependencies": {
+ "dep1": "^1.1.1"
+}
+</code></pre><p>Then <code>npm update --save</code> will install <code>dep1@1.2.2</code> (i.e., <code>latest</code>),
+and <code>package.json</code> will be modified:</p>
+<pre><code>"dependencies": {
+ "dep1": "^1.2.2"
+}
+</code></pre><p>Note that <code>npm</code> will only write an updated version to <code>package.json</code>
+if it installs a new package.</p>
+<h3 id="updating-globally-installed-packages">Updating Globally-Installed Packages</h3>
+<p><code>npm update -g</code> will apply the <code>update</code> action to each globally installed
+package that is <code>outdated</code> -- that is, has a version that is different from
+<code>latest</code>.</p>
+<p>NOTE: If a package has been upgraded to a version newer than <code>latest</code>, it will
+be <em>downgraded</em>.</p>
