A Javascript implementation of the [Levenshtein algorithm](http://en.wikipedia.org/wiki/Levenshtein_distance) with locale-specific collator support. This uses [fastest-levenshtein](https://github.com/ka-weihe/fastest-levenshtein) under the hood.

## Features

* Works in node.js and in the browser.

* Locale-sensitive string comparisons if needed.

* Comprehensive test suite.

## Installation

```bash

$ npm install fast-levenshtein

```

**CDN**

The latest version is now also always available at https://npm-cdn.com/pkg/fast-levenshtein/ 

## Examples

**Default usage**

```javascript

var levenshtein = require('fast-levenshtein');

var distance = levenshtein.get('back', 'book');   // 2

var distance = levenshtein.get('我愛你', '我叫你');   // 1

```

**Locale-sensitive string comparisons**

It supports using [Intl.Collator](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Collator) for locale-sensitive  string comparisons:

```javascript

var levenshtein = require('fast-levenshtein');

levenshtein.get('mikailovitch', 'Mikhaïlovitch', { useCollator: true});

// 1

```

## Building and Testing

To build the code and run the tests:

```bash

$ npm install -g grunt-cli

$ npm install

$ npm run build

```

## Performance

This uses [fastest-levenshtein](https://github.com/ka-weihe/fastest-levenshtein) under the hood.
