> Write data to a file, replacing the file if it already exists and creating any intermediate directories if they don't already exist. Thin wrapper around node's native fs methods.

## Install

Install with [npm](https://www.npmjs.com/):

```sh
$ npm install --save write
```

## Usage

```js
var writeFile = require('write');
```

## API

### [writeFile](index.js#L40)

Asynchronously writes data to a file, replacing the file if it already exists and creating any intermediate directories if they don't already exist. Data can be a string or a buffer. Returns a promise if a callback function is not passed.

**Params**

* `filepath` **{string|Buffer|integer}**: filepath or file descriptor.
* `data` **{string|Buffer|Uint8Array}**: String to write to disk.
* `options` **{object}**: Options to pass to [fs.writeFile](https://nodejs.org/api/fs.html#fs_fs_writefile_file_data_options_callback) and/or [mkdirp](https://github.com/substack/node-mkdirp)
* `callback` **{Function}**: (optional) If no callback is provided, a promise is returned.

**Example**

```js
var writeFile = require('write');
writeFile('foo.txt', 'This is content...', function(err) {
  if (err) console.log(err);
});

// promise
writeFile('foo.txt', 'This is content...')
  .then(function() {
    // do stuff
  });
```

### [.promise](index.js#L82)

The promise version of [writeFile](#writefile). Returns a promise.

**Params**

* `filepath` **{string|Buffer|integer}**: filepath or file descriptor.
* `val` **{string|Buffer|Uint8Array}**: String or buffer to write to disk.
* `options` **{object}**: Options to pass to [fs.writeFile](https://nodejs.org/api/fs.html#fs_fs_writefile_file_data_options_callback) and/or [mkdirp](https://github.com/substack/node-mkdirp)
* `returns` **{Promise}**

**Example**

```js
var writeFile = require('write');
writeFile.promise('foo.txt', 'This is content...')
  .then(function() {
    // do stuff
  });
```

### [.sync](index.js#L120)

The synchronous version of [writeFile](#writefile). Returns undefined.

**Params**

* `filepath` **{string|Buffer|integer}**: filepath or file descriptor.
* `data` **{string|Buffer|Uint8Array}**: String or buffer to write to disk.
* `options` **{object}**: Options to pass to [fs.writeFileSync](https://nodejs.org/api/fs.html#fs_fs_writefilesync_file_data_options) and/or [mkdirp](https://github.com/substack/node-mkdirp)
* `returns` **{undefined}**

**Example**

```js
var writeFile = require('write');
writeFile.sync('foo.txt', 'This is content...');
```

### [.stream](index.js#L151)

Uses `fs.createWriteStream` to write data to a file, replacing the file if it already exists and creating any intermediate directories if they don't already exist. Data can be a string or a buffer. Returns a new [WriteStream](https://nodejs.org/api/fs.html#fs_class_fs_writestream) object.

**Params**

* `filepath` **{string|Buffer|integer}**: filepath or file descriptor.
* `options` **{object}**: Options to pass to [mkdirp](https://github.com/substack/node-mkdirp) and [fs.createWriteStream](https://nodejs.org/api/fs.html#fs_fs_createwritestream_path_options)
* `returns` **{Stream}**: Returns a new [WriteStream](https://nodejs.org/api/fs.html#fs_class_fs_writestream) object. (See [Writable Stream](https://nodejs.org/api/stream.html#stream_class_stream_writable)).

**Example**

```js
var fs = require('fs');
var writeFile = require('write');
fs.createReadStream('README.md')
  .pipe(writeFile.stream('a/b/c/other-file.md'))
  .on('close', function() {
    // do stuff
  });
```
