💾 FsMan

A file system utility that can be used with Node.js fs module.

Installation

FsMan requires Node.js 18.x or higher, and the repository is serviced through NPM.

After configuring the node environment, you can simply run the following command.

# via npm
$ npm install fsman

# via yarn
$ yarn add fsman

# via pnpm
$ pnpm install fsman

How to use

Using named import (Multiple utilities in a single require) - Recommend

import { isHiddenFile, humanizeFileSize } from 'fsman';

async function main() {
  console.log(await isHiddenFile('.hiddenFile')); // true
  console.log(humanizeFileSize(1000000)); // '976.56 KB'
}

Using whole class (multiple utilities simultaneously with one object)

import fsman from 'fsman';

async function main() {
  console.log(await fsman.isHiddenFile('.hiddenFile')); // true
  console.log(fsman.humanizeFileSize(1000000)); // '976.56 KB'
}

Methods

isHiddenFile (Promise<Boolean>)

Checks whether a file or folder in the specified path is a hidden file. Determines system hidden files for Windows and the presence or absence of a .(dot) for Linux and macOS or other operating systems.

If Windows fails to get the file properties, it assumes the file is not hidden.

• filePath <String>: File or directory path
• isWindows <Boolean>: Whether the target operating system to be checked is Windows

console.log(await fsman.isHiddenFile('text.txt')); // false
console.log(await fsman.isHiddenFile('.hiddenFile')); // true
console.log(await fsman.isHiddenFile('.hiddenFile', true)); // false (Files with no hidden attribute applied in Windows)

isFileExists (Promise<Boolean>)

Returns true if the file at the given path exists.

• filePath <String>: File or directory path

console.log(await fsman.isFileExists('text.txt')); // true
console.log(await fsman.isFileExists('not-exist.txt')); // false

humanizeFileSize (<String>)

Returns the given byte argument as a human-friendly string.

• bytes <Number>: Converts it to a human-friendly string via the bytes provided here.
• decimals <Number> (Default: 2): Specifies the number of decimal places to represent.

console.log(await fsman.humanizeFileSize(1000000)); // '976.56 KB'
console.log(await fsman.humanizeFileSize(100000000, 3)); // '95.367 MB'

toValidFilePath (<String>)

Remove invalid or unnecessary characters in the path.

• filePath <String>: File or directory path
• isWindows <Boolean>: Whether the target operating system to be checked is Windows

console.log(fsman.toValidFilePath('C:\\Windows\\System32\\'), true); // 'C:\Windows\System32'
console.log(fsman.toValidFilePath('home/user/.bashrc')); // '/home/user/.bashrc'

getFilePathLevel (<Number>)

Determine how many steps the current path is. The root path (/ or C:\) begins with step 1.

• filePath <String>: File or directory path

// Include 'C:\' root path
console.log(fsman.getFilePathLevel('C:\\Windows\\System32')); // 3
// Include '/' root path
console.log(fsman.getFilePathLevel('/home/user')); // 3

getParentFilePath (<String>)

Returns the parent path one level above the given path.

• filePath <String>: File or directory path

console.log(fsman.getParentFilePath('C:\\Windows\\System32', true)); // 'C:\Windows'
console.log(fsman.getParentFilePath('/home/user/text.txt')); // '/home/user'

toPosixFilePath (<String>)

Returns the given path as a path in POSIX format (usually used by Linux). For example, a Windows path will be converted to / instead of \\.

• filePath <String>: File or directory path

console.log(fsman.toPosixFilePath('C:\\Windows\\System32')); // 'C:/Windows/System32'

joinFilePath (<String>)

Combines paths for each operating system according to the given parameter values.

• isWindows <Boolean>: Whether the target operating system to be checked is Windows
• paths <String[]>: A path value consisting of one or more strings. Omit the path separator and put it in the parameter.

console.log(fsman.joinFilePath(true, 'C:\\', 'Windows', 'System32')); // 'C:\Windows\System32'
console.log(fsman.joinFilePath(false, 'home', '/user', '.bashrc')); // '/home/user/.bashrc'

isValidFileName (<Boolean>)

Determines whether the passed path or filename is using a system-accepted string (Also check the valid file length). Returns false if the name is not available.

• filePath <String>: File or directory path
• unixType <Boolean?>: Passes true if the file type is unix type.

console.log(fsman.isValidFileName('C:\\Windows\\System32*')); // false
console.log(fsman.isValidFileName('/home/user/.bashrc', true)); // true

createFolder (<Void>)

Creates a directory with the specified path. Ignores the operation if the directory already exists.

• filePath <String>: File or directory path
• recursive <Boolean?|true>: Recursively creates all directories in the given path.

fsman.createFolder('/home/user/a/b/c');

getFileName (<String>)

Returns the file name within the path.

• filePath <String>: File or directory path
• withExtension <Boolean?|false>: Returns the name with extension.

console.log(fsman.getFileName('/home/user/test.txt')); // 'test'
console.log(fsman.getFileName('/home/user/test.txt', true)); // 'test.txt'

normalizeFile (<String>)

Changes a string (usually file names) according to the Unicode normalization form method used by each operating system.

• filePath <String>: File or directory path
• normalizationForm <'NFC'|'NFD'|'NFKC'|'NFKD'|undefined>: Normalization method (If value is undefined, NFC is used.)

console.log(fsman.normalizeFile('안녕하세요Hello.txt', 'NFC')); // '안녕하세요Hello.txt'
console.log(fsman.normalizeFile('안녕하세요Hello.txt', 'NFD')); // '안녕하세요Hello.txt'

getFileExtension (<String>)

Returns the file extension from the given file path. An empty string value is returned for files without extension.

• filePath <String>: File or directory path
• isWindows <Boolean?|false>: If the given file path is a Windows system path

console.log(fsman.getFileExtension('/home/user/test.txt')); // 'txt'
console.log(fsman.getFileExtension('/home/user/test.txt.sample')); // 'sample'

getFileInfo (<FileStat>)

Returns file or directory information as an easy-to-understand object.

• filePath <String>: File or directory path

console.log(fsman.getFileInfo('/home/user/test.txt'));

Examples of returned values:

{
  success: true, // Whether the file stat import was successful
  isDirectory: false,
  ext: 'txt',
  size: 33,
  sizeHumanized: '33 Bytes',
  name: 'test.txt',
  dirname: 'user',
  path: '/home/user/test.txt',
  created: 1652581984, // Unix timestamp
  modified: 1652581984 // Unix timestamp
}

headFile (<String|Null>)

Returns the first line of the specified text file path. The length argument is the total number of lines to print. Default is 1.

console.log(fsman.headFile('/test/targets/hello.md')); // '# Hello, World!'

tailFile (<String|Null>)

• filePath <String>: File or directory path
• length <number>: Number of lines of text to return

console.log(fsman.tailFile('/test/targets/hello.md')); // '--- Hello End ---'

touchFile (<Void>)

Create a file of empty data. If the same file already exists, it is ignored.

fsman.touchFile('/home/user/test.txt');

touchFileWithDummy (<Void>)

Creates a file with the specified size in bytes.

• filePath <String>: File or directory path

fsman.touchFileWithDummy('/home/user/test.txt', 100000);

deleteFile (<Void>)

Delete files in the specified path. If the file does not exist in the path, it is ignored.

• filePath <String>: File or directory path

fsman.deleteFile('/home/user/text.txt');

moveFile (<Void>)

Moves a file in the specified file path to another path.

fsman.moveFile('/home/user/text.txt', '/home/user/text2.txt');

deleteAllFileFromDirectory (<Void>)

Deletes all files in the specified directory path. However, the directory is preserved.

• directoryPath <String>: Directory path

fsman.deleteAllFileFromDirectory('/home/user/Downloads');

hashFile (Promise<String>)

Returns the file in the specified path as a value hashed by a specific algorithm. The default algorithm is md5. This method uses a Promise to return a valid hash value.

• filePath <String>: File or directory path
