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](https://docs.npmjs.com/cli/install)

## API

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

### writeFile(_file_, _data_ [, _options_])

_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);
```
