@nodelib/fs.scandir

List files and directories inside the specified directory.

:bulb: Highlights

The package is aimed at obtaining information about entries in the directory.

:moneybag: Returns useful information: name, path, dirent and stats (optional).
:gear: On Node.js 10.10+ uses the mechanism without additional calls to determine the entry type. See old and modern mode.
:link: Can safely work with broken symbolic links.

Install

npm install @nodelib/fs.scandir

Usage

import * as fsScandir from '@nodelib/fs.scandir';

fsScandir.scandir('path', (error, stats) => { /* … */ });

API

.scandir(path, [optionsOrSettings], callback)

Returns an array of plain objects (Entry) with information about entry for provided path with standard callback-style.

fsScandir.scandir('path', (error, entries) => { /* … */ });
fsScandir.scandir('path', {}, (error, entries) => { /* … */ });
fsScandir.scandir('path', new fsScandir.Settings(), (error, entries) => { /* … */ });

.scandirSync(path, [optionsOrSettings])

Returns an array of plain objects (Entry) with information about entry for provided path.

const entries = fsScandir.scandirSync('path');
const entries = fsScandir.scandirSync('path', {});
const entries = fsScandir.scandirSync(('path', new fsScandir.Settings());

path

Required: true
Type: string | Buffer | URL

A path to a file. If a URL is provided, it must use the file: protocol.

optionsOrSettings

Required: false
Type: Options | Settings
Default: An instance of Settings class

An Options object or an instance of Settings class.

:book: When you pass a plain object, an instance of the Settings class will be created automatically. If you plan to call the method frequently, use a pre-created instance of the Settings class.

Settings([options])

A class of full settings of the package.

const settings = new fsScandir.Settings({ followSymbolicLinks: false });

const entries = fsScandir.scandirSync('path', settings);

Entry

name — The name of the entry (unknown.txt).
path — The path of the entry relative to call directory (root/unknown.txt).
dirent — An instance of fs.Dirent class. On Node.js below 10.10 will be emulated by DirentFromStats class.
stats (optional) — An instance of fs.Stats class.

For example, the scandir call for tools directory with one directory inside:

{
	dirent: Dirent { name: 'typedoc', /* … */ },
	name: 'typedoc',
	path: 'tools/typedoc'
}

Options

stats

Type: boolean
Default: false

Adds an instance of fs.Stats class to the Entry.

:book: Always use fs.readdir without the withFileTypes option. ??TODO??

followSymbolicLinks

Type: boolean
Default: false

Follow symbolic links or not. Call fs.stat on symbolic link if true.

`throwErrorOnBrokenSymbolicLink`

Type: boolean
Default: true

Throw an error when symbolic link is broken if true or safely use lstat call if false.

`pathSegmentSeparator`

Type: string
Default: path.sep

By default, this package uses the correct path separator for your OS (\ on Windows, / on Unix-like systems). But you can set this option to any separator character(s) that you want to use instead.

`fs`

Type: FileSystemAdapter
Default: A default FS methods

By default, the built-in Node.js module (fs) is used to work with the file system. You can replace any method with your own.

interface FileSystemAdapter {
	lstat?: typeof fs.lstat;
	stat?: typeof fs.stat;
	lstatSync?: typeof fs.lstatSync;
	statSync?: typeof fs.statSync;
	readdir?: typeof fs.readdir;
	readdirSync?: typeof fs.readdirSync;
}

const settings = new fsScandir.Settings({
	fs: { lstat: fakeLstat }
});

`old` and `modern` mode

This package has two modes that are used depending on the environment and parameters of use.

old

Node.js below 10.10 or when the stats option is enabled

When working in the old mode, the directory is read first (fs.readdir), then the type of entries is determined (fs.lstat and/or fs.stat for symbolic links).

modern

Node.js 10.10+ and the stats option is disabled

In the modern mode, reading the directory (fs.readdir with the withFileTypes option) is combined with obtaining information about its entries. An additional call for symbolic links (fs.stat) is still present.

This mode makes fewer calls to the file system. It's faster.
