Install

npm install file-manager-js

Usage

// require all functions
const fileManager = require('file-manager-js');

// OR specific functions
const { list, removeFile, rename } = require('file-manager-js');

.stat(path)

promisified fs.stat. retrieves the stats of a file or directory. https://nodejs.org/api/fs.html#fs_class_fs_stats

fileManager.stat('./test.txt')
  .then((stats) => // stats)
  .catch((error) => // error);

.info(path)

returns an extended stats object that includes size (bytes) and type of the path

// file info
fileManager.info('./test.txt').then((info) => {
  /*
   {
     size: 19,
     type: 'file',
     ...
   }
  */
}).catch((error) => // error);

// directory info
fileManager.info('./test')
  .then((info) => {
    /*
     {
       size: 2146, // size of all files in dir tree
       type: 'directory',
       ...
     }
    */
  })
  .catch((error) => // error);

.join(path1, path2)

join two paths. a delegate to require('path').join

let p = fileManager.join('a/b/c', 'd/e/f'); // a/b/c/d/e/f

.list(path)

list first-level files and directories inside a directory

// path can be an absolute path using __dirname
fileManager.list('./project')
  .then((entries) => {
    /*
     {
       files: ['index.js', 'README.md'],
       dirs : ['lib', 'node_modules', 'test']
     }
    */
  })
  .catch((error) => // error)

.listDeep(path)

list in-depth files and directories inside a directory

fileManager.listDeep('./content')
  .then((entries) => {
    /*
     {
       files: ['test.txt', 'abc/test.csv', 'new/content/test/a.txt'],
       dirs : ['abc', 'abc/test', 'new/content/test']
     }
    */
  })
  .catch((error) => // error)

.exists(path)

checks if a path (file or directory) exists and resolve with true or false

fileManager.exists('./content')
  .then((exists) => // true)
  .catch((error) => // error)

fileManager.exists('./newContent')
  .then((exists) => // false)
  .catch((error) => // error)

.createDir(path)

creates a single directory or a directory tree

// create a directory tree
fileManager.createDir('./a/b/c/d')
  .then((path) => // path = ./a/b/c/d)
  .catch((error) => // error)

.createFile(path)

creates a file and creates the directory tree in the path if not exists

// creates a directory structure then the file
fileManager.createFile('./x/y/z/test.txt')
  .then((path) => // path = ./x/y/z/test.txt)
  .catch((error) => // error)

.readFile(path)

reads entire file content

fileManager.readFile('./x/y/z/test.txt')
  .then((content) => // content is instance of Buffer)
  .catch((error) => // error)

.removeDir(path)

removes a directory or directory tree with all its content

// remvove a/b/c/d + a/b/c +  a/b/test.txt + a/b + a
fileManager.removeDir('./a')
  .then((path) => // ./a)
  .catch((error) => // error)

.removeFile(path)

removes a file

// removed ./test.txt
fileManager.removeFile('./test.txt')
  .then((path) => // ./test.txt)
  .catch((error) => // error)

.rename(oldPath, newPath)

rename a file or directory

// rename file ./test.txt to ./ttt.txt
fileManager.rename('./test.txt', './ttt.txt')
  .then((newPath) => // ./ttt.txt)
  .catch((error) => // error)
