.SH DESCRIPTION
|
|
|
.P
|
|
|
This command shows data about a package and prints it to the stream
|
|
|
referenced by the \fBoutfd\fP config, which defaults to stdout\.
|
|
|
.P
|
|
|
To show the package registry entry for the \fBconnect\fP package, you can do
|
|
|
this:
|
|
|
.P
|
|
|
.RS 2
|
|
|
.nf
|
|
|
npm view connect
|
|
|
.fi

.RE
|
|
|
.P
|
|
|
The default version is "latest" if unspecified\.
|
|
|
.P
|
|
|
Field names can be specified after the package descriptor\.
|
|
|
For example, to show the dependencies of the \fBronn\fP package at version
|
|
|
0\.3\.5, you could do the following:
|
|
|
.P
|
|
|
.RS 2
|
|
|
.nf
|
|
|
npm view ronn@0\.3\.5 dependencies
|
|
|
.fi
|
|
|
.RE
|
|
|
.P
|
|
|
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:
|
|
|
.P
|
|
|
.RS 2
|
|
|
.nf
|
|
|
npm view npm repository\.url
|
|
|
.fi
|
|
|
.RE
|
|
|
.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
|
|
|
.RS 2
|
|
|
.nf
|
|
|
npm view opts@$(npm view ronn dependencies\.opts)
|
|
|
.fi
|
|
|
.RE
|
|
|
.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
|
|
|
.RS 2
|
|
|
.nf
|
|
|
npm view express contributors\.email
|
|
|
.fi
|
|
|
.RE
|
|
|
.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
|
|
|
.RS 2
|
|
|
.nf
|
|
|
npm view express contributors[0]\.email
|
|
|
.fi
|
|
|
.RE
|
|
|
.P
|
|
|
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:
|
|
|
.P
|
|
|
.RS 2
|
|
|
.nf
|
|
|
npm view express contributors\.name contributors\.email
|
|
|
.fi
|
|
|
.RE
|
|
|
.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 npm help 5 \fBpackage\.json\fP for more on this\.)
|
|
|
.P
|
|
|
.RS 2
|
|
|
.nf
|
|

npm view npm contributors
|

.RE
|
|
|
.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
|
|
|
.RS 2
|
|
|
.nf
|
|
|
npm view yui3@'>0\.5\.4' dependencies\.jsdom
|
|
|
.fi
|
|
|
.RE
|
|
|
.P
|
|

To show the \fBconnect\fP package version history, you can do
|
|
|
this:
|
|
|
.P
|
|
|
.RS 2
|
|
|
.nf
|
|
|
npm view connect versions
|
|
|
.fi
|

.RE
|
|
|
.SH OUTPUT
|
|
|
.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\. If the field is an object, it will be output as a JavaScript object literal\.
|
|
|
.P
|
|
|
If the \-\-json flag is given, the outputted fields will be JSON\.
|
|
|
.P
|
|
|
If the version range matches multiple versions, than each printed value
|
|
|
will be prefixed with the version it applies to\.
|
|
|
.P
|
|
|
If multiple fields are requested, than each of them are prefixed with
|
|
|
the field name\.
