App-cache-dir NPM

app-cache-dir

Get a path of the standard cache directory for a given application

const appCacheDir = require('app-cache-dir');

// On most Linuxes
appCacheDir('my-app'); //=> '/root/shinnn/.cache/my-app'

// On macOS
appCacheDir('my-app'); //=> '/Users/shinnn/.cache/my-app'

// On Windows
appCacheDir('my-app'); //=> 'C:\\Users\\shinnn\\AppData\\Local\\my-app\\cache'

Installation

Use npm.

npm install app-cache-dir

API

const appCacheDir = require('app-cache-dir');

appCacheDir(appName)

appName: string (application name)
Return: string (absolute directory path)

It resolves an application name into its standard cache directory presented in the Atom issue tracker, with following the environment variables XDG_CACHE_HOME (POSIX) and LOCALAPPDATA (Windows).

Basically it results:

~/.cache/${appName} on POSIX
C:\\Users\\${username}\\AppData\Local\${appName}\cache on Windows

// On macOS

appCacheDir('hi'); //=> '/Users/shinnn/.cache/hi'

process.env.XDG_CACHE_HOME = '/foo/bar/';

appCacheDir('hi'); //=> '/foo/bar/hi'

When it cannot resolve the cache path, for exmaple both HOME and XDG_CACHE_HOME are empty, it returns ${os.tmpdir()}/${appName}/cache as a last resort.
