<p>This command shows data about a package and prints it to the stream
|
|
|
|
|
referenced by the <code>outfd</code> config, which defaults to stdout.</p>
|
|
|
|
|
|
|
|
|
|
<p>To show the package registry entry for the <code>connect</code> package, you can do
|
|
|
|
|
this:</p>
|
|
|
|
|
|
|
|
|
|
<pre><code>npm view connect</code></pre>
|
|
|
|
|
|
|
|
|
|
<p>The default version is "latest" 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
|
|
|
|
|
0.3.5, you could do the following:</p>
|
|
|
|
|
|
|
|
|
|
<pre><code>npm view ronn@0.3.5 dependencies</code></pre>
|
|
|
|
|
|
|
|
|
|
<p>You can view child field by separating them with a period.
|
|
|
|
|
To view the git repository URL for the latest version of npm, you could
|
|
|
|
|
do this:</p>
|
|
|
|
|
|
|
|
|
|
<pre><code>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
|
|
|
|
|
opts that ronn depends on, you can do this:</p>
|
|
|
|
|
|
|
|
|
|
<pre><code>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 names for the "express" project, you can do this:</p>
|
|
|
|
|
|
|
|
|
|
<pre><code>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 do this:</p>
|
|
|
|
|
|
|
|
|
|
<pre><code>npm view express contributors[0].email</code></pre>
|
|
|
|
|
|
|
|
|
|
<p>Multiple fields may be specified, and will be printed one after another.
|
|
|
|
|
For exampls, to get all the contributor names and email addresses, you
|
|
|
|
|
can do this:</p>
|
|
|
|
|
|
|
|
|
|
<pre><code>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 npm contributors in
|
|
|
|
|
the shortened string format. (See <code><a href="../doc/json.html">json(1)</a></code> for more on this.)</p>
|
|
|
|
|
|
|
|
|
|
<pre><code>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 jsdom
|
|
|
|
|
was required by each matching version of yui3:</p>
|
|
|
|
|
|
|
|
|
|
<pre><code>npm view yui3@'>0.5.4' dependencies.jsdom</code></pre>
|
|
|
|
|
|
|
|
|
|
<h2 id="OUTPUT">OUTPUT</h2>
|
|
|
|
|
|
|
|
|
|
<p>If only a single string field for a single version is output, then it
|
|
|
|
|
will not be colorized or quoted, so as to enable piping the output to
|
|
|
|
|
another command.</p>
|
|
|
|
|
|
|
|
|
|
<p>If the version range matches multiple versions, than each printed value
|
|
|
|
|
will be prefixed with the version it applies to.</p>
|
|
|
|
|
|
|
|
|
|
<p>If multiple fields are requested, than each of them are prefixed with
|
|
|
|
|
the field name.</p>
