@stdlib/os-configdir NPM

configdir

Return a directory for user-specific configuration files.

Installation

npm install @stdlib/os-configdir

Usage

var configdir = require( '@stdlib/os-configdir' );

configdir( [path] )

Returns a directory for user-specific configuration files.

var dir = configdir();
// e.g., returns '/Users/<username>/Library/Preferences'

To append a path to the base directory, provide a path argument.

var dir = configdir( 'appname/config' );
// e.g., returns '/Users/<username>/Library/Preferences/appname/config'

On non-Windows platforms, if the function is unable to locate the current user's home directory, the function returns null. Similarly, on Windows platforms, if the function is unable to locate an application data directory, the function also returns null.

Notes

On Windows platforms, the function first checks for a LOCALAPPDATA environment variable before checking for an APPDATA environment variable. This means that machine specific user configuration files have precedence over roaming user configuration files.

Examples

var configdir = require( '@stdlib/os-configdir' );

console.log( configdir( 'appy/config' ) );

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
