node-fs-writefile-promise


fs.writeFile wrapped in an ES6 Promise

``js
const writeFile = require('node-fs-writefile-promise');

writeFile('path/to/file', 'string or buffer data')
.then(() => console.log('data written successfully to disk'))
.catch(err => console.error(err.message));
`

A simple ES6 Promise-based wrapper around Node's built-in [writeFile][fs.writeFile].

Installation

npm i node-fs-writefile-promise

npm install docs

API

`js
const writeFile = require('node-fs-writefile-promise');
`

$3

_file_: String | Buffer | Integer filename or file descriptor
_data_: String | Buffer
_options_: Object | String ([fs.writeFile] options)

Returns: ([Promise][promise])

Once the file is written, the returned promise will be [_resolved_][resolve] with no arguments.

If there is an error, the returned promise will be [_rejected_][reject] with an error as its first argument.

`js
const writeFile = require('node-fs-writefile-promise');

const onFulfilled = () => console.log('File written successfully');
const onRejected = err => console.log('Cannot write to the file');

writeFile('path/to/file', 'string or buffer data').then(onFulfilled, onRejected);

writeFile('path/to/file', 'string or buffer data')
.then(onFulfilled)
.catch(onRejected);
