Synchronously write a file and create its ancestor directories if needed
const {readFileSync} = require('fs');
const outputFileSync = require('output-file-sync');
outputFileSync('foo/bar/baz.txt', 'Hi!');
readFileSync('foo/bar/baz.txt', 'utf8'); //=> 'Hi!'
This module is very similar to fs-extra's fs.outputFileSync
method, but different in the following points:
output-file-sync accepts mkdirp options.
const {statSync} = require('fs');
const outputFileSync = require('output-file-sync');
outputFileSync('foo/bar', 'content', {mode: 33260});
statSync('foo').mode; //=> 33260
output-file-sync validates its arguments strictly, and prints highly informative error message.
npm install output-file-sync
const outputFileSync = require('output-file-sync');
path: string
data: string
, Buffer
or Uint8Array
options: Object
(options for fs.writeFileSync and mkdirp) or string
(encoding)
Return: string
if it creates more than one directories, otherwise null
It writes the data to a file synchronously. If ancestor directories of the file don't exist, it creates the directories before writing the file.
const {statSync} = require('fs');
const outputFileSync = require('output-file-sync');
// When the directory `foo/bar` exists
outputFileSync('foo/bar/baz/qux.txt', 'Hello', 'utf-8');
statSync('foo/bar/baz').isDirectory(); //=> true
statSync('foo/bar/baz/qux.txt').isFile(); //=> true
It returns the directory path just like mkdirp.sync:
Returns the first directory that had to be created, if any.
const dir = outputFileSync('foo/bar/baz.txt', 'Hello');
dir === path.resolve('foo'); //=> true
All options for fs.writeFileSync and mkdirp are available.
Additionally, you can pass fileMode
and dirMode
options to set different permission between the file and directories.
Set the mode of a file, overriding mode
option.
Set the modes of directories, overriding mode
option.
outputFileSync('dir/file', 'content', {dirMode: '0745', fileMode: '0644'});
fs.statSync('dir').mode.toString(8); //=> '40745'
fs.statSync('dir/file').mode.toString(8); //=> '100644'
