@nodelib/fs.stat

Get the status of a file with some features.

:bulb: Highlights

Wrapper around standard method fs.lstat and fs.stat with some features.

:beginner: Normally follows symbolic link.
:gear: Can safely work with broken symbolic link.

Install

npm install @nodelib/fs.stat

Usage

import * as fsStat from '@nodelib/fs.stat';

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

Also available with the promise interface:

import * as fsStat from '@nodelib/fs.stat/promises';

await fsStat.stat('path');

API

.stat(path, [optionsOrSettings], callback)

Returns an instance of fs.Stats class for provided path with standard callback-style.

:book: If you want to use the Promise API, import @nodelib/fs.stat/promises or use util.promisify.

fsStat.stat('path', (error, stats) => { /* … */ });
fsStat.stat('path', {}, (error, stats) => { /* … */ });
fsStat.stat('path', new fsStat.Settings(), (error, stats) => { /* … */ });

.statSync(path, [optionsOrSettings])

Returns an instance of fs.Stats class for provided path.

const stats = fsStat.stat('path');
const stats = fsStat.stat('path', {});
const stats = fsStat.stat('path', new fsStat.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 fsStat.Settings({ followSymbolicLink: false });

const stats = fsStat.stat('path', settings);

Options

`followSymbolicLink`

Type: boolean
Default: true

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

`markSymbolicLink`

Type: boolean
Default: false

Mark symbolic link by setting the return value of isSymbolicLink function to always true (even after fs.stat).

:book: Can be used if you want to know what is hidden behind a symbolic link, but still continue to know that it is a symbolic link.

`throwErrorOnBrokenSymbolicLink`

Type: boolean
Default: true

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

`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;
}

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