## README

# widest-line

> Get the visual width of the widest line in a string - the number of columns required to display it

Some Unicode characters are [fullwidth](https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms) and use double the normal width. [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code) are stripped and doesn't affect the width.

Useful to be able to know the maximum width a string will take up in the terminal.

## Install

```sh
npm install widest-line
```

## Usage

```js
import widestLine from 'widest-line';

widestLine('古\n\u001B[1m@\u001B[22m');
//=> 2
```
