file-manager-js
Description
It uses node filesystem to manage files and directories on the local storage through an enhanced promise interface. It can list/create/remove files and directories recursively with promises.Install
npm install file-manager-jsUsage
// 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#fsclassfsstats
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)Build
