NAME

       npm-cache - Manipulates packages cache

SYNOPSIS

       npm cache add <tarball file>
       npm cache add <folder>
       npm cache add <tarball url>
       npm cache add <name>@<version>

       npm cache ls [<path>]

       npm cache clean [<path>]

DESCRIPTION

       Used to add, list, or clear the npm cache folder.

       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.

       ls     Show the data in the cache. Argument is a path to show in the cache folder. Works a
              bit like the find program, but limited by the depth config.

       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.

DETAILS

       npm  stores  cache  data in $HOME/.npm. For each package that is added to the cache, three
       pieces of information are stored in {cache}/{name}/{version}:

       .../package/
              A folder containing the package contents as they appear in the tarball.

       .../package.json
              The package.json file, as npm sees it, with overlays applied and a _id attribute.

       .../package.tgz
              The tarball for that version.

       Additionally, whenever a registry request is made, a .cache.json file  is  placed  at  the
       corresponding URI, to store the ETag and the requested data.

       Commands  that  make  non-essential  registry  requests  (such  as search and view, or the
       completion scripts) generally specify a  minimum  timeout.  If  the  .cache.json  file  is
       younger than the specified timeout, then they do not make an HTTP request to the registry.

CONFIGURATION

       Default: $HOME/.npm on Posix, or $HOME/npm-cache on Windows.
