# write-pkg [![Build Status](https://travis-ci.org/sindresorhus/write-pkg.svg?branch=master)](https://travis-ci.org/sindresorhus/write-pkg)

> Write a `package.json` file

Writes atomically and creates directories for you as needed. Sorts dependencies when writing. Preserves the indentation if the file already exists.


## Install

```
$ npm install write-pkg
```


## Usage

```js
const path = require('path');
const writePackage = require('write-pkg');

(async () => {
	await writePackage({foo: true});
	console.log('done');

	await writePackage(__dirname, {foo: true});
	console.log('done');

	await writePackage(path.join('unicorn', 'package.json'), {foo: true});
	console.log('done');
})();
```
