output-file

npm version Build Status codecov

Write a file and create its ancestor directories if needed

const {readFile} = require('fs').promises;
const outputFile = require('output-file');

(async () => {
  await outputFile('foo/bar/baz.txt', 'Hi!');
  await readFile('foo/bar/baz.txt', 'utf8'); //=> 'Hi!'
})();

This module is very similar to fs-extra's fs.outputFile, but has the following features fs-extra doesn't have:

  • Support for various non-string path types – Buffer, Uint8Array and URL
  • An option to set mode of created directories

Installation

Use npm.

npm install output-file

API

const outputFile = require('output-file');

outputFile(path, data , options)

path: string | Buffer | Uint8Array | URL
data: string | Buffer | TypedArray | DataView
options: Object (options) or string (file encoding)
Return: Promise<undefined>

It writes the data to a file asynchronously. If ancestor directories of a file don't exist, it creates those directories before writing a file.

const {stat} = require('fs').promises;
const outputFile = require('output-file');

// When the directory `foo/bar` exists

(async () => {
  await outputFile('foo/bar/baz/qux.txt', 'Hello');

  (await stat('foo/bar/baz')).isDirectory(); //=> true
  (await stat('foo/bar/baz/qux.txt')).isFile(); //=> true
})();

options

All options for fs.promises.writeFile() and fs.promises.mkdir(), except for mode and recursive, are supported.

recursive option is enabled by default and cannot be disabled.

Instead of mode option, use the followings:

options.fileMode

Set mode of a file.

options.dirMode

Set mode of directories.

const {stat} = require('fs').promises;
const outputFile = require('output-file');

(async () => {
  await outputFile('dir/file', 'content', {
    dirMode: '0745',
    fileMode: '0644'
  });

  (await stat('dir')).mode.toString(8); //=> '40745'
  (await stat('dir/file')).mode.toString(8); //=> '100644'
})();
