@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`.

## <tt>throwErrorOnBrokenSymbolicLink</tt>

- Type: `boolean`
- Default: `true`

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

## <tt>pathSegmentSeparator</tt>

- 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.

## <tt>fs</tt>

- 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 }
});

# <tt>old</tt> and <tt>modern</tt> 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.
