Installation

npm install --save fs-promise-lite

npm install --save-dev fs-promise-lite

Utilisation

the same api with original fs

const fs = require('fs-promise-lite')

fs.readFile('file1.txt','utf8')
  .then((data) => {
   console.log(data)
  })

Supported

fs.readdir(dir,options)

fs.readFile(file,options)

fs.stat(file)

fs.writeFile(file,data,options)

fs.unlink(file)

fs.mkdir(dirname,mode)

fs.rmdir(dirname)

fs.appendFile(file,data,options)

fs.chmod(path,mode)

fs.chown(path,uid,gid)

fs.symlink(target,path,type)

Exceptional

1. readFiles(fileArr,options) - read many files

const fs = require('fs-promise-lite')

let arr = ['file1.txt','file2.txt','file3.txt']

Promise.all(fs.readFiles(arr,'utf8'))
       .then(console.log)

// [['file1.txt','data1'],['file2.txt','data2'],['file3.txt','data3']]

2. unlinks(fileArr) - delete many files

const fs = require('fs-promise-lite')

let arr = ['file1.txt','file2.txt','file3.txt']

Promise.all(fs.unlinks(arr))
       .then(() => {
         console.log('ok')
       })

3. writeFiles(files_datas,options)

const fs = require('fs-promise-lite')

let files_datas = [
 ['file1.txt','data1'],
 ['file2.txt','data2'],
 ['file3.txt','data3']
]

Promise.all(fs.writeFiles(files_datas,'utf8'))
       .then(() => {
         console.log('ok')
       })

4. stats(files)

const fs = require('fs-promise-lite')

let arr = ['file1.txt','file2.txt','file3.txt']

Promise.all(fs.stats(arr))
       .then(console.log)

/*
[['file1.txt',Object_stat1],['file2.txt',Object_stat2],['file3.txt',Object_stat3]]
which Object_stats is like:

Stats {
  dev: 66311,
  mode: 33188,
  nlink: 1,
  uid: 0,
  gid: 0,
  rdev: 0,
