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-module
This 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/.cache
If 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-dir
Usage
const findCacheDir = require('find-cache-dir');
findCacheDir({name: 'unicorns'});
//=> '/user/path/node-modules/.cache/unicorns'
API
findCacheDir([options])
Finds the cache directory 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
Should be the same as your project name in package.json.
files
Type: Array `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()
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.js'
This is helpful for actually putting actual files in the cache!
