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
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:
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:
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:
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:
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:
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:
"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
package.json(5) for more on this.)
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:
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.
