Package description
The @nodelib/fs.scandir package is a Node.js library that provides a way to read the contents of a directory with the ability to get detailed information about each entry. It supports both synchronous and asynchronous operations and can handle errors gracefully. It is a low-level package that can be used to build more complex file system utilities.
Asynchronous directory scanning
This feature allows you to asynchronously scan a directory and obtain an array of entries, each representing a file or directory within the scanned directory.
const { scandir } = require('@nodelib/fs.scandir');
scandir('/path/to/directory', (error, entries) => {
if (error) {
console.error(error);
return;
}
entries.forEach((entry) => {
console.log(entry);
});
});Synchronous directory scanning
This feature allows you to synchronously scan a directory and obtain an array of entries, similar to the asynchronous version but blocking the event loop until the operation is complete.
const { scandirSync } = require('@nodelib/fs.scandir');
try {
const entries = scandirSync('/path/to/directory');
entries.forEach((entry) => {
console.log(entry);
});
} catch (error) {
console.error(error);
}Stream-based directory scanning
This feature provides a stream interface for directory scanning, allowing you to process entries as they are read, which can be more memory-efficient for large directories.
const { scandirStream } = require('@nodelib/fs.scandir');
const stream = scandirStream('/path/to/directory');
stream.on('data', (entry) => {
console.log(entry);
});
stream.on('error', (error) => {
console.error(error);
});
stream.on('end', () => {
console.log('Scanning is complete.');
});fs-extra is a package that extends the built-in fs module with additional methods and improvements. It includes methods for directory scanning, but it is a more comprehensive file system utility library.
readdirp is a package that provides recursive directory reading with a stream interface. It is similar to @nodelib/fs.scandir's stream feature but focuses on recursive scanning and filtering.
glob is a package that allows pattern matching for filenames. It can be used to scan directories and filter files based on glob patterns, which is different from the straightforward directory listing provided by @nodelib/fs.scandir.
Readme
List files and directories inside the specified directory.
The package is aimed at obtaining information about entries in the directory.
name, path, dirent and stats (optional).npm install @nodelib/fs.scandir
import * as fsScandir from '@nodelib/fs.scandir';
fsScandir.scandir('path', (error, stats) => { /* … */ });
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) => { /* … */ });
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());
truestring | Buffer | URLA path to a file. If a URL is provided, it must use the file: protocol.
falseOptions | SettingsSettings classAn Options object or an instance of Settings class.
:book: When you pass a plain object, an instance of the
Settingsclass will be created automatically. If you plan to call the method frequently, use a pre-created instance of theSettingsclass.
A class of full settings of the package.
const settings = new fsScandir.Settings({ followSymbolicLinks: false });
const entries = fsScandir.scandirSync('path', settings);
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. When the stats option is enabled, it 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'
}
booleanfalseAdds an instance of fs.Stats class to the Entry.
:book: Always use
fs.readdirwithout thewithFileTypesoption. ??TODO??
booleanfalseFollow symbolic links or not. Call fs.stat on symbolic link if true.
throwErrorOnBrokenSymbolicLinkbooleantrueThrow an error when symbolic link is broken if true or safely use lstat call if false.
pathSegmentSeparatorstringpath.sepBy 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.
fsFileSystemAdapterBy 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 }
});
