3> Get the path of the parent module
4
5Node.js exposes `module.parent`, but it only gives you the first cached parent, which is not necessarily the actual parent.
6

8## Install
9
10```
11$ npm install parent-module
12```
13
14
15## Usage
16
17```js
18// bar.js
19const parentModule = require('parent-module');
20
21module.exports = () => {
22 console.log(parentModule());
23 //=> '/Users/sindresorhus/dev/unicorn/foo.js'
24};
25```

27```js
28// foo.js

35## API
36
37### parentModule([filepath])
38
39By default, it will return the path of the immediate parent.
40
41#### filepath
42
43Type: `string`<br>
44Default: [`__filename`](https://nodejs.org/api/globals.html#globals_filename)
45
46Filepath of the module of which to get the parent path.
47
48Useful if you want it to work [multiple module levels down](https://github.com/sindresorhus/parent-module/tree/master/fixtures/filepath).

51## Tip
52
53Combine it with [`read-pkg-up`](https://github.com/sindresorhus/read-pkg-up) to read the package.json of the parent module.
54
55```js
56const path = require('path');
57const readPkgUp = require('read-pkg-up');
58const parentModule = require('parent-module');
59
60console.log(readPkgUp.sync({cwd: path.dirname(parentModule())}).pkg);
61//=> {name: 'chalk', version: '1.0.0', …}
62```
