|
|
|
|
|
|
<p>This command will print to stdout all the versions of packages that are
|
|
|
|
|
installed, as well as their dependencies, in a tree-structure. It will also
|
|
|
|
|
return that data using the callback.</p>
|
|
|
|
|
|
|
|
|
|
<p>This command does not take any arguments, but args must be defined.
|
|
|
|
|
Beyond that, if any arguments are passed in, npm will politely warn that it
|
|
|
|
|
does not take positional arguments, though you may set config flags
|
|
|
|
|
like with any other command, such as <code>global</code> to list global packages.</p>
|
|
|
|
|
|
|
|
|
|
<p>It will print out extraneous, missing, and invalid packages.</p>
|
|
|
|
|
|
|
|
|
|
<p>If the silent parameter is set to true, nothing will be output to the screen,
|
|
|
|
|
but the data will still be returned.</p>
|
|
|
|
|
|
|
|
|
|
<p>Callback is provided an error if one occurred, the full data about which
|
|
|
|
|
packages are installed and which dependencies they will receive, and a
|
|
|
|
|
"lite" data object which just shows which versions are installed where.
|
|
|
|
|
Note that the full data object is a circular structure, so care must be
|
|
|
|
|
taken if it is serialized to JSON.</p>

<p>List packages in the global install prefix instead of in the current

project.</p>

|
|
|
|
|
|
<p>Note, if parseable is set or long isn't set, then duplicates will be trimmed.
|
|
|
|
|
This means that if a submodule a same dependency as a parent module, then the
|
|

dependency will only be output once.</p>
