.SH "DESCRIPTION"
Used to add, list, or clear the npm cache folder\.
.
.IP "\(bu" 4
add:
Add the specified package to the local cache\.  This command is primarily
intended to be used internally by npm, but it can provide a way to
add data to the local installation cache explicitly\.
.
.IP "\(bu" 4
ls:
Show the data in the cache\.  Argument is a path to show in the cache
folder\.  Works a bit like the \fBfind\fR program, but limited by the \fBdepth\fR config\.
.
.IP "\(bu" 4
clean:
Delete data out of the cache folder\.  If an argument is provided, then
it specifies a subpath to delete\.  If no argument is provided, then
the entire cache is cleared\.
.
.IP "" 0
.
.SH "DETAILS"
npm stores cache data in the directory specified in \fBnpm config get cache\fR\|\.
For each package that is added to the cache, three pieces of information are
stored in \fB{cache}/{name}/{version}\fR:
.
.IP "\(bu" 4
\|\.\.\./package/:
A folder containing the package contents as they appear in the tarball\.
.
.IP "\(bu" 4
\|\.\.\./package\.json:
The package\.json file, as npm sees it, with overlays applied and a _id attribute\.
.
.IP "\(bu" 4
\|\.\.\./package\.tgz:
The tarball for that version\.
.
.IP "" 0
.
.P
Additionally, whenever a registry request is made, a \fB\|\.cache\.json\fR file
is placed at the corresponding URI, to store the ETag and the requested
data\.
.
.P
Commands that make non\-essential registry requests (such as \fBsearch\fR and \fBview\fR, or the completion scripts) generally specify a minimum timeout\.
If the \fB\|\.cache\.json\fR file is younger than the specified timeout, then
they do not make an HTTP request to the registry\.
.
.SH "CONFIGURATION"
.
.SS "cache"
Default: \fB~/\.npm\fR on Posix, or \fB%AppData%/npm\-cache\fR on Windows\.
.
.P
The root cache folder\.
