find-cache-directory

> Finds the common standard cache directory

The nyc and AVA projects decided to standardize on a common directory structure for storing cache information:

``sh


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
`

Install

`sh
npm install find-cache-directory
`

Usage

`js
import findCacheDirectory from 'find-cache-directory';

findCacheDirectory({name: 'unicorns'});
//=> '/user/path/node-modules/.cache/unicorns'
`

API

$3

Finds the cache directory using the given options.

The algorithm checks for the CACHE_DIR environmental variable and uses it if it is not set to true, false, 1 or 0. If one is not found, it 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 undefined if package.json was never found or if the node_modules directory is unwritable.

#### options

Type: object

##### name

Required\
Type: string

Should be the same as your project name in package.json.

##### files

Type: 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

Create the directory synchronously before returning.

Tips

- To test modules using this package, set the CACHE_DIR environment variable to temporarily override the directory that is resolved.
