12 <h1><a href="../cli/npm-view.html">npm-view</a></h1> <p>View registry info</p>
13 <h2 id="synopsis">SYNOPSIS</h2>
14 <pre><code>npm view [@<scope>/]<name>[@<version>] [<field>[.<subfield>]...]
15 npm v [@<scope>/]<name>[@<version>] [<field>[.<subfield>]...]
16 </code></pre><h2 id="description">DESCRIPTION</h2>
17 <p>This command shows data about a package and prints it to the stream
18 referenced by the <code>outfd</code> config, which defaults to stdout.</p>
19 <p>To show the package registry entry for the <code>connect</code> package, you can do
21 <pre><code>npm view connect
22 </code></pre><p>The default version is "latest" if unspecified.</p>
23 <p>Field names can be specified after the package descriptor.
24 For example, to show the dependencies of the <code>ronn</code> package at version
25 0.3.5, you could do the following:</p>
26 <pre><code>npm view ronn@0.3.5 dependencies
27 </code></pre><p>You can view child fields by separating them with a period.
28 To view the git repository URL for the latest version of npm, you could
30 <pre><code>npm view npm repository.url
31 </code></pre><p>This makes it easy to view information about a dependency with a bit of
32 shell scripting. For example, to view all the data about the version of
33 opts that ronn depends on, you can do this:</p>
34 <pre><code>npm view opts@$(npm view ronn dependencies.opts)
35 </code></pre><p>For fields that are arrays, requesting a non-numeric field will return
36 all of the values from the objects in the list. For example, to get all
37 the contributor names for the "express" project, you can do this:</p>
38 <pre><code>npm view express contributors.email
39 </code></pre><p>You may also use numeric indices in square braces to specifically select
40 an item in an array field. To just get the email address of the first
41 contributor in the list, you can do this:</p>
42 <pre><code>npm view express contributors[0].email
43 </code></pre><p>Multiple fields may be specified, and will be printed one after another.
44 For exampls, to get all the contributor names and email addresses, you
46 <pre><code>npm view express contributors.name contributors.email
47 </code></pre><p>"Person" fields are shown as a string if they would be shown as an
48 object. So, for example, this will show the list of npm contributors in
49 the shortened string format. (See <code><a href="../files/package.json.html"><a href="../files/package.json.html">package.json(5)</a></a></code> for more on this.)</p>
50 <pre><code>npm view npm contributors
51 </code></pre><p>If a version range is provided, then data will be printed for every
52 matching version of the package. This will show which version of jsdom
53 was required by each matching version of yui3:</p>
54 <pre><code>npm view yui3@'>0.5.4' dependencies.jsdom
55 </code></pre><h2 id="output">OUTPUT</h2>
56 <p>If only a single string field for a single version is output, then it
57 will not be colorized or quoted, so as to enable piping the output to
58 another command. If the field is an object, it will be output as a JavaScript object literal.</p>
59 <p>If the --json flag is given, the outputted fields will be JSON.</p>
60 <p>If the version range matches multiple versions, than each printed value
61 will be prefixed with the version it applies to.</p>
62 <p>If multiple fields are requested, than each of them are prefixed with
64 <h2 id="see-also">SEE ALSO</h2>
