Manipulates packages cache
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>]
aliases: npm cache clear, npm cache rm
Used to add, list, or clean 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 deleted.
npm stores cache data in the directory specified in npm config get cache.
For each package that is added to the cache, three pieces of information are
stored in {cache}/{name}/{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. This is stored in {cache}/{hostname}/{path}/.cache.json.
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.
Default: ~/.npm on Posix, or %AppData%/npm-cache on Windows.
The root cache folder.
