Detect the language of text.

What’s so cool about franc?

1. franc supports more languages^(†) than any other library, or Google;
2. franc is easily forked to support 300+ languages;
3. franc is just as fast as the competition.

† - If humans write in the language, on the web, and the language has more than one million speakers, franc detects it.

Installation

npm:

$ npm install franc

Component:

$ component install wooorm/franc

Bower:

$ bower install franc

Usage

var franc = require('franc');

franc('Alle menslike wesens word vry'); // "afr"
franc('এটি একটি ভাষা একক IBM স্ক্রিপ্ট'); // "ben"
franc('Alle mennesker er født frie og'); // "nno"
franc(''); // "und"

franc.all('O Brasil caiu 26 posições em');
/*
 * [
 *   [ 'por', 5507 ],
 *   [ 'glg', 6270 ],
 *   [ 'src', 6292 ],
 *   [ 'lav', 6391 ],
 *   [ 'cat', 6432 ],
 *   [ 'spa', 6481 ],
 *   [ 'bos', 6509 ],

 * ]
 */

franc.all(''); // [ [ 'und', 1 ] ]

Note!: franc returns the "und" language code for an undetermined language. This happens when the input value is too short to give a significant answer.
