| <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> |
