# homedir-polyfill [](https://www.npmjs.com/package/homedir-polyfill) [](https://npmjs.org/package/homedir-polyfill) [](https://travis-ci.org/doowb/homedir-polyfill) [](https://ci.appveyor.com/project/doowb/homedir-polyfill)
> Node.js os.homedir polyfill for older versions of node.js.
## Install
Install with [npm](https://www.npmjs.com/):
```sh
$ npm install --save homedir-polyfill
```
## Usage
```js
var homedir = require('homedir-polyfill');
console.log(homedir());
//=> /Users/doowb
```
## Reasoning
This library is a polyfill for the [node.js os.homedir](https://nodejs.org/api/os.html#os_os_homedir) method found in modern versions of node.js.
This implementation tries to follow the implementation found in `libuv` by finding the current user using the `process.geteuid()` method and the `/etc/passwd` file. This should usually work in a linux environment, but will also fallback to looking at user specific environment variables to build the user's home directory if neccessary.
Since `/etc/passwd` is not available on windows platforms, this implementation will use environment variables to find the home directory.
In modern versions of node.js, [os.homedir](https://nodejs.org/api/os.html#os_os_homedir) is used.
