    $ npm i --save fsman


    import fsman from 'fsman';
    async function main () {
        console.log(await fsman.isHidden('.hiddenFile')); // true
        console.log(fsman.humanizeSize(1000000)); // '976.56 KB'


    isHidden (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.

    • filePath <String>: File or directory path
    • isWindows <Boolean>: Whether the target operating system to be checked is Windows
    console.log(await fsman.isHidden('text.txt')); // false
    console.log(await fsman.isHidden('.hiddenFile')); // true
    console.log(await fsman.isHidden('.hiddenFile', true)); // false (Files with no hidden attribute applied in Windows)

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

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

    joinPath (<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.joinPath(true, 'C:\\', 'Windows', 'System32')); // 'C:\Windows\System32'
    console.log(fsman.joinPath(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

    mkdir (<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.

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

    stat (<FileStat>)

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

    • filePath <String>: File or directory path

    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

    touch (<Void>)

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

    • filePath <String>: File or directory path

    rm (<Void>)

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

    • filePath <String>: File or directory path

    mv (<Void>)

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

    • filePath <String>: File or directory path
    • targetFilePath <String>: Path of file to move
    console.log('/home/user/text.txt', '/home/user/text2.txt'));

    empty (<Void>)

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

    • directoryPath <String>: Directory path

    hash (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
    • algorithm <'md5'|'sha1'|'sha256'|'sha512'>: OpenSSL algorithm to be used for file hashing
    console.log(await fsman.hash('/home/user/text.txt', 'sha1')); // '38851813f75627d581c593f3ccfb7061dd013fbd'
