</code></pre>

|
|
<h3 id="description">Description</h3>
|
||
|
|
<p>This command shows data about a package and prints it to stdout.</p>
|
||
|
|
<p>As an example, to view information about the <code>connect</code> package from the registry, you would run:</p>
|
||
|
|
<pre><code class="language-bash">npm view connect
|
||
|
|
</code></pre>
|
||
|
|
<p>The default version is <code>"latest"</code> if unspecified.</p>
|
||
|
|
<p>Field names can be specified after the package descriptor.
|
||
|
|
For example, to show the dependencies of the <code>ronn</code> package at version
|
||
|
|
<code>0.3.5</code>, you could do the following:</p>
|
||
|
|
<pre><code class="language-bash">npm view ronn@0.3.5 dependencies
|
||
|
|
</code></pre>
|
||
|
|
<p>You can view child fields by separating them with a period.
|
||
|
|
To view the git repository URL for the latest version of <code>npm</code>, you would run the following command:</p>
|
||
|
|
<pre><code class="language-bash">npm view npm repository.url
|
||
|
|
</code></pre>
|
||
|
|
<p>This makes it easy to view information about a dependency with a bit of
|
||
|
|
shell scripting. For example, to view all the data about the version of
|
||
|
|
<code>opts</code> that <code>ronn</code> depends on, you could write the following:</p>
|
||
|
|
<pre><code class="language-bash">npm view opts@$(npm view ronn dependencies.opts)
|
||
|
|
</code></pre>
|
||
|
|
<p>For fields that are arrays, requesting a non-numeric field will return
|
||
|
|
all of the values from the objects in the list. For example, to get all
|
||
|
|
the contributor email addresses for the <code>express</code> package, you would run:</p>
|
||
|
|
<pre><code class="language-bash">npm view express contributors.email
|
||
|
|
</code></pre>
|
||
|
|
<p>You may also use numeric indices in square braces to specifically select
|
||
|
|
an item in an array field. To just get the email address of the first
|
||
|
|
contributor in the list, you can run:</p>
|
||
|
|
<pre><code class="language-bash">npm view express contributors[0].email
|
||
|
|
</code></pre>
|
||
|
|
<p>If the field value you are querying for is a property of an object, you should run:</p>
|
||
|
|
<pre><code class="language-bash">npm view express time'[4.8.0]'
|
||
|
|
</code></pre>
|
||
|
|
<p>Multiple fields may be specified, and will be printed one after another.
|
||
|
|
For example, to get all the contributor names and email addresses, you
|
||
|
|
can do this:</p>
|
||
|
|
<pre><code class="language-bash">npm view express contributors.name contributors.email
|
||
|
|
</code></pre>
|
||
|
|
<p>"Person" fields are shown as a string if they would be shown as an
|
||
|
|
object. So, for example, this will show the list of <code>npm</code> contributors in
|
||
|
|
the shortened string format. (See <a href="../configuring-npm/package-json.html"><code>package.json</code></a> for more on this.)</p>
|
||
|
|
<pre><code class="language-bash">npm view npm contributors
|
||
|
|
</code></pre>
|
||
|
|
<p>If a version range is provided, then data will be printed for every
|
||
|
|
matching version of the package. This will show which version of <code>jsdom</code>
|
||
|
|
was required by each matching version of <code>yui3</code>:</p>
|
||
|
|
<pre><code class="language-bash">npm view yui3@'>0.5.4' dependencies.jsdom
|
||
|
|
</code></pre>
|
||
|
|
<p>To show the <code>connect</code> package version history, you can do
|
||
|
|
this:</p>
|
||
|
|
<pre><code class="language-bash">npm view connect versions
|
||
|
|
</code></pre>

<h3 id="configuration">Configuration</h3>
|
||
|
|
<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="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>
|
||
|
|
<h4 id="workspaces"><code>workspaces</code></h4>
|
||
|
|
<ul>
|
||
|
|
<li>Default: null</li>
|
||
|
|
<li>Type: null or Boolean</li>
|
||
|
|
</ul>
|
||
|
|
<p>Set to true to run the command in the context of <strong>all</strong> configured
|
||
|
|
workspaces.</p>
|
||
|
|
<p>Explicitly setting this to false will cause commands like <code>install</code> to
|
||
|
|
ignore workspaces altogether. When not set explicitly:</p>
|
||
|
|
<ul>
|
||
|
|
<li>Commands that operate on the <code>node_modules</code> tree (install, update, etc.)
|
||
|
|
will link workspaces into the <code>node_modules</code> folder. - Commands that do
|
||
|
|
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>
|
||
|
|
</ul>
|
||
|
|
<p>This value is not exported to the environment for child processes.</p>
|
||
|
|
<h4 id="include-workspace-root"><code>include-workspace-root</code></h4>
|
||
|
|
<ul>
|
||
|
|
<li>Default: false</li>
|
||
|
|
<li>Type: Boolean</li>
|
||
|
|
</ul>
|
||
|
|
<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="output">Output</h3>
|
||
|
|
<p>If only a single string field for a single version is output, then it
|
||
|
|
will not be colorized or quoted, to enable piping the output to
|
||
|
|
another command. If the field is an object, it will be output as a JavaScript object literal.</p>
|
||
|
|
<p>If the <code>--json</code> flag is given, the outputted fields will be JSON.</p>
|
||
|
|
<p>If the version range matches multiple versions then each printed value
|
||
|
|
will be prefixed with the version it applies to.</p>
|
||
|
|
<p>If multiple fields are requested, then each of them is prefixed with
|
||
|
|
the field name.</p>
