NAME

       npm-view - View registry info

   Synopsis
         npm view [<@scope>/]<name>[@<version>] [<field>[.<subfield>]...]

         aliases: info, show, v

   Description
       This command shows data about a package and prints it to the stream referenced by the outfd config, which
       defaults to stdout.

       To show the package registry entry for the connect package, you can do this:

         npm view connect

       The default version is "latest" if unspecified.

       Field names can be specified after the package descriptor.  For example, to show the dependencies of  the
       ronn package at version 0.3.5, you could do the following:

         npm view ronn@0.3.5 dependencies

       You  can  view  child  fields  by  separating them with a period.  To view the git repository URL for the
       latest version of npm, you could do this:

         npm view npm repository.url

       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:

         npm view opts@$(npm view ronn dependencies.opts)

       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:

         npm view express contributors.email

       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:

         npm view express contributors[0].email

       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:

         npm view express contributors.name contributors.email

       "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 npm help package.json for more on
       this.)

         npm view npm contributors

       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:

         npm view yui3@'>0.5.4' dependencies.jsdom

       To show the connect package version history, you can do this:

         npm view connect versions

   Output
       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. If the field is an object, it  will  be  output  as  a
       JavaScript object literal.

       If the --json flag is given, the outputted fields will be JSON.

       If the version range matches multiple versions, than each printed value will be prefixed with the version
       it applies to.

       If multiple fields are requested, than each of them are prefixed with the field name.
