13 <pre><code>npm view <name>[@<version>] [<field>[.<subfield>]...]
14 npm v <name>[@<version>] [<field>[.<subfield>]...]</code></pre>
16 <h2 id="DESCRIPTION">DESCRIPTION</h2>
18 <p>This command shows data about a package and prints it to the stream
19 referenced by the <code>outfd</code> config, which defaults to stdout.</p>
21 <p>To show the package registry entry for the <code>connect</code> package, you can do
24 <pre><code>npm view connect</code></pre>
26 <p>The default version is "latest" if unspecified.</p>
28 <p>Field names can be specified after the package descriptor.
29 For example, to show the dependencies of the <code>ronn</code> package at version
30 0.3.5, you could do the following:</p>
32 <pre><code>npm view ronn@0.3.5 dependencies</code></pre>
34 <p>You can view child field by separating them with a period.
35 To view the git repository URL for the latest version of npm, you could
38 <pre><code>npm view npm repository.url</code></pre>
40 <p>This makes it easy to view information about a dependency with a bit of
41 shell scripting. For example, to view all the data about the version of
42 opts that ronn depends on, you can do this:</p>
44 <pre><code>npm view opts@$(npm view ronn dependencies.opts)</code></pre>
46 <p>For fields that are arrays, requesting a non-numeric field will return
47 all of the values from the objects in the list. For example, to get all
48 the contributor names for the "express" project, you can do this:</p>
50 <pre><code>npm view express contributors.email</code></pre>
52 <p>You may also use numeric indices in square braces to specifically select
53 an item in an array field. To just get the email address of the first
54 contributor in the list, you can do this:</p>
56 <pre><code>npm view express contributors[0].email</code></pre>
58 <p>Multiple fields may be specified, and will be printed one after another.
59 For exampls, to get all the contributor names and email addresses, you
62 <pre><code>npm view express contributors.name contributors.email</code></pre>
64 <p>"Person" fields are shown as a string if they would be shown as an
65 object. So, for example, this will show the list of npm contributors in
66 the shortened string format. (See <code><a href="../files/package.json.html">package.json(5)</a></code> for more on this.)</p>
68 <pre><code>npm view npm contributors</code></pre>
70 <p>If a version range is provided, then data will be printed for every
71 matching version of the package. This will show which version of jsdom
72 was required by each matching version of yui3:</p>
74 <pre><code>npm view yui3@'>0.5.4' dependencies.jsdom</code></pre>
76 <h2 id="OUTPUT">OUTPUT</h2>
78 <p>If only a single string field for a single version is output, then it
79 will not be colorized or quoted, so as to enable piping the output to
80 another command. If the field is an object, it will be output as a JavaScript object literal.</p>
82 <p>If the --json flag is given, the outputted fields will be JSON.</p>
84 <p>If the version range matches multiple versions, than each printed value
85 will be prefixed with the version it applies to.</p>
87 <p>If multiple fields are requested, than each of them are prefixed with
90 <h2 id="SEE-ALSO">SEE ALSO</h2>
