Readme
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.
Install with npm
:
$ npm install diskusage
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.
If no callback is supplied check
will instead return a Promise<DiskUsage>
that you can await.
available
: Disk space available to the current user (i.e. Linux reserves 5% for root)free
: Disk space physically freetotal
: Total disk space (free + used)checkSync
only takes the path argument. It returns the same info
on success, throws an Error
on failure.
const disk = require('diskusage');
const os = require('os');
let path = os.platform() === 'win32' ? 'c:' : '/';
// Callbacks
disk.check(path, function(err, info) {
if (err) {
console.log(err);
} else {
console.log(info.available);
console.log(info.free);
console.log(info.total);
}
});
// Promise
async function getFreeSpace(path) {
try {
const { free } = await disk.check(path);
console.log(`Free space: ${free}`);
return free
} catch (err) {
console.error(err)
return 0
}
}
// Or without using async/await
disk.check(path)
.then(info => console.log(`free: ${info.free}`))
.catch(err => console.error(err))
// Synchronous
try {
let info = disk.checkSync(path);
console.log(info.available);
console.log(info.free);
console.log(info.total);
}
catch (err) {
console.log(err);
}
The module has an embedded .d.ts file. You can use import * as diskusage from 'diskusage'
.
type DiskUsage = {
available: number;
free: number;
total: number;
}
export function check(path: string, callback: (error?: Error, result?: DiskUsage) => void): void;
export function check(path: string): Promise<DiskUsage>
export function checkSync(path: string): DiskUsage;
To see a demo of this library see the demo/
folder.
You can run it with node: (node 8+ required)
node ./demo/
