fast-folder-size


Node CLI or module to calculate folder size.

It uses:

- Sysinternals DU on Windows, automatically downloaded at
installation time because the license does not allow redistribution. See below about specifying the download location.
- native du on other platforms

Installation

``
npm i fast-folder-size
`

Usage

$3

`js
const { promisify } = require('util')
const fastFolderSize = require('fast-folder-size')
const fastFolderSizeSync = require('fast-folder-size/sync')

// callback
fastFolderSize('.', (err, bytes) => {
if (err) {
throw err
}

console.log(bytes)
})

// promise
const fastFolderSizeAsync = promisify(fastFolderSize)
const bytes = await fastFolderSizeAsync('.')

console.log(bytes)

// sync
const bytes = fastFolderSizeSync('.')

console.log(bytes)
`

#### Aborting

The non-sync version of the API also supports AbortSignal, to abort the operation while in progress.

`js
const fastFolderSize = require('fast-folder-size')

const controller = new AbortController()

fastFolderSize('.', { signal: controller.signal }, (err, bytes) => {
if (err) {
throw err
}

console.log(bytes)
})

controller.abort()
`

$3

`bash
fast-folder-size .
`

$3

By default the Sysinternals DU.zip is downloaded from https://download.sysinternals.com/files/DU.zip.

If you need to change this, e.g. to download from an internal package repository
or re-use an existing du.zip, you can set the FAST_FOLDER_SIZE_DU_ZIP_LOCATION environment variable.

For example:

`shell
export FAST_FOLDER_SIZE_DU_ZIP_LOCATION="https://your.internal.repository/DU.zip"
`

or

`shell
export FAST_FOLDER_SIZE_DU_ZIP_LOCATION="D://download/du.zip"
