find-cache-dir

find-cache-dir

Finds the common standard cache directory

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

Install

npm install find-cache-dir

Usage

import findCacheDirectory from 'find-cache-dir';

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

API

findCacheDirectory(options?)

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 find-cache-dir, set the CACHE_DIR environment variable to temporarily override the directory that is resolved.

Similar packages

Other packages similar to find-cache-dir

cache-manager

cache-manager is a more general-purpose caching framework that supports multiple storage backends and provides a flexible API for caching. It is not specifically designed for finding cache directories but can be used to manage cache data in a variety of contexts.

mkdirp

mkdirp is a package that allows you to create a new directory and its parent directories if they do not exist. While it does not provide cache directory finding capabilities, it can be used in conjunction with find-cache-dir to ensure that the cache directory is created.

tmp

tmp is a utility for creating temporary files and directories. It can be used to create temporary cache directories, but unlike find-cache-dir, it does not find or manage persistent cache directories across runs.
