find-cache-dir 
Finds the common standard cache directory.
Recently the nyc and AVA projects
decided to standardize on a common directory structure for storing cache
information:
# nyc
./node_modules/.cache/nyc
# ava
./node_modules/.cache/ava
# your-module
./node_modules/.cache/your-moduleThis module makes it easy to correctly locate the cache directory according to this shared spec. If this pattern becomes ubiquitous, clearing the cache for multiple dependencies becomes easy and consistent:
rm -rf ./node_modules/.cacheIf you decide to adopt this pattern, please file a PR adding your name to the list of adopters below.
Install
$ npm install --save find-cache-dirUsage
const findCacheDir = require('find-cache-dir');
findCacheDir({name: 'unicorns'});
//=> /user/path/node-modules/.cache/unicornsAPI
findCacheDir(options)
Finds the cache dir using the supplied options. The algorithm tries
to find a package.json file, searching every parent
directory of the cwd specified (or implied from other
options). It returns a string containing the absolute path
to the cache directory, or null if
package.json was never found.
options
name
Required
Type: string
This should be the same as your project name in
package.json.
files
Type: array of string
An array of files that will be searched for a common parent
directory. This common parent directory will be used in lieu of the
cwd option below.
cwd
Type: string
Default process.cwd()
The directory to start searching for a package.json
from.
create
Type: boolean
Default false
If true, the directory will be created synchronously
before returning.
thunk
Type: boolean
Default false
If true, this modifies the return type to be a function
that is a thunk for path.join(theFoundCacheDirectory).
const thunk = findCacheDir({name: 'foo', thunk: true});
thunk();
//=> /some/path/node_modules/.cache/foo
thunk('bar.js')
//=> /some/path/node_modules/.cache/foo/bar.js
thunk('baz', 'quz.js')
//=> /some/path/node_modules/.cache/foo/baz/quz.jsThis is helpful for actually putting actual files in the cache!
