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

> Get the username of the current user

This module is meant for informational purposes and not for secure identification.


## Install

```
$ npm install username
```


## Usage

```js
const username = require('username');

(async () => {
	console.log(await username());
	//=> 'sindresorhus'
})();
```


## API

It first tries to get the username from the `SUDO_USER` `LOGNAME` `USER` `LNAME` `USERNAME` environment variables. Then falls back to `$ id -un` on macOS / Linux and `$ whoami` on Windows, in the rare case none of the environment variables are set. The result is cached.

### username()

Returns a `Promise<string>` with the username.

### username.sync()

Returns the username.
