| <h1><a href="../api/npm-view.html">npm-view</a></h1> <p>View registry info</p> |
| <h2 id="synopsis">SYNOPSIS</h2> |
| <pre><code>npm.commands.view(args, [silent,] callback) |
| </code></pre><h2 id="description">DESCRIPTION</h2> |
| <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>The "args" parameter is an ordered list that closely resembles the command-line |
| usage. The elements should be ordered such that the first element is |
| the package and version (package@version). The version is optional. After that, |
| the rest of the parameters are fields with optional subfields ("field.subfield") |
| which can be used to get only the information desired from the registry.</p> |
| <p>The callback will be passed all of the data returned by the query.</p> |
| <p>For example, to get the package registry entry for the <code>connect</code> package, |
| you can do this:</p> |
| <pre><code>npm.commands.view(["connect"], callback) |
| </code></pre><p>If no version is specified, "latest" is assumed.</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.commands.view(["ronn@0.3.5", "dependencies"], callback) |
| </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.commands.view(["npm", "repository.url"], callback) |
| </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.commands.view(["express", "contributors.email"], callback) |
| </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.commands.view(["express", "contributors[0].email"], callback) |
| </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.commands.view(["express", "contributors.name", "contributors.email"], callback) |
| </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>npm help json</code> for more on this.)</p> |
| <pre><code>npm.commands.view(["npm", "contributors"], callback) |
| </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.commands.view(["yui3@>0.5.4", "dependencies.jsdom"], callback) |
| </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> |
| <p>Console output can be disabled by setting the 'silent' parameter to true.</p> |
| <h2 id="return-value">RETURN VALUE</h2> |
| <p>The data returned will be an object in this formation:</p> |
| <pre><code>{ <version>: |
| { <field>: <value> |
| , ... } |
| , ... } |
| </code></pre><p>corresponding to the list of fields selected.</p> |
