node-diskusage

This module implements platform specific bindings to obtain disk usage information on Windows and POSIX platforms. Windows support is backed by GetDiskFreeSpaceEx and POSIX is implemented with statvfs.

Installation

$ npm install @amilajack/diskusage

Usage

The module exposes two functions. check takes a path/mount point as the first argument and a callback as the second. The callback takes two arguments err and info. err will be an Error if something went wrong. info contains three members: available, free and total in bytes.

• available: Disk space available to the current user (i.e. Linux reserves 5% for root)
• free: Disk space physically free
• total: Total disk space (free + used)

checkSync only takes the path argument. It returns the same info on success, throws an Error on failure.

Examples

import disk from '@amilajck/diskusage';
import os from 'os';

const path = os.platform() === 'win32' ? 'c:' : '/';
const info = disk.checkSync(path);
console.log(info.available);
console.log(info.free);
console.log(info.total);
