Since foo depends directly on \fBbar@1\.2\.3\fP and \fBbaz@1\.2\.3\fP, those are
|
||
|
|
installed in foo's \fBnode_modules\fP folder\.
|
||

Even though the latest copy of blerg is 1\.3\.7, foo has a specific
|
||
|
|
dependency on version 1\.2\.5\. So, that gets installed at [A]\. Since the
|
||
|
|
parent installation of blerg satisfies bar's dependency on \fBblerg@1\.x\fP,
|
||
|
|
it does not install another copy under [B]\.
|
||
|
|
.P
|
||
|
|
Bar [B] also has dependencies on baz and asdf, so those are installed in
|
||
|
|
bar's \fBnode_modules\fP folder\. Because it depends on \fBbaz@2\.x\fP, it cannot
|
||
|
|
re\-use the \fBbaz@1\.2\.3\fP installed in the parent \fBnode_modules\fP folder [D],
|
||
|
|
and must install its own copy [C]\.
|
||
|
|
.P
|
||
|
|
Underneath bar, the \fBbaz \-> quux \-> bar\fP dependency creates a cycle\.
|
||
|
|
However, because bar is already in quux's ancestry [B], it does not
|
||
|
|
unpack another copy of bar into that folder\.
|
||
|
|
.P
|
||
|
|
Underneath \fBfoo \-> baz\fP [D], quux's [E] folder tree is empty, because its
|
||
|
|
dependency on bar is satisfied by the parent folder copy installed at [B]\.
|
||

For a graphical breakdown of what is installed where, use \fBnpm ls\fP\|\.

.P
|

|
|
Upon publishing, npm will look in the \fBnode_modules\fP folder\. If any of
|
||
|
|
the items there are not in the \fBbundledDependencies\fP array, then they will
|
||
|
|
not be included in the package tarball\.
|
||
|
|
.P
|
||
|
|
This allows a package maintainer to install all of their dependencies
|
||
|
|
(and dev dependencies) locally, but only re\-publish those items that
|
||
|
|
cannot be found elsewhere\. See npm help \fBpackage\.json\fP for more information\.
