write-files

Write multiple files parallelly

const writeFiles = require('write-files');

writeFiles({
  'foo.txt': 'foo',
  'bar.txt': 'bar'
}, err => {
  if (err) {
    throw err;
  }

  fs.readFileSync('foo.txt', 'utf8'); //=> 'foo'
  fs.readFileSync('bar.txt', 'utf8'); //=> 'bar'
});

Installation

Use npm.

npm install write-files

API

const writeFiles = require('write-files');

writeFiles(nameDataMap [, options], callback)

nameDataMap: Object ({"filename0": "contents0", "filename1": "contents1", ... })
options: Object or String (directly passed to write-file-atomic)
callback: Function

The API is quite the same as write-file-atomic's. The only difference is write-files requires an Object as its first argument: Each key of the object will be used as a file path, and each value of the object will be written to a path where the corresponding key indicates.

After one or more file output failed, it passes an error to its callback function and removes already created files.

const glob = require('glob');
const writeFiles = require('write-files');

writeFiles({
  file1: '1', // success
  file2: '2', // success
  file3: '3', // fail
  file4: '4'  // success
}, err => {
  !!err; //=> true

  glob('file{1,2,3,4}' err, () => {
    paths.length; //=> 0
  });
});
