npm install output-file
Write a file and create its ancestor directories if needed
``javascript
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
`
npm install output-file
`javascript`
const outputFile = require('output-file');
path: string | Buffer | Uint8Array | URL string | Buffer | TypedArray | DataView
data: Object
options: (options) or string (file encoding) Promise
Return:
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.
`javascript
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.
`javascript
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'
})();
