node-cld

Language detection for Javascript. Based on the CLD2 (Compact Language Detector) library from Google.

Highly optimized for space and speed. Runs about 10x faster than other libraries. Detects over 160 languages. Full test coverage. Runs on Linux, OS X, and Windows.

Installation

$ npm install cld

Linux users, make sure you have g++ >= 4.8. If this is not an option, you should be able to install node-cld 2.4.4 even with an older g++ build.

Examples

Simple

const cld = require('cld');

// As a promise
cld.detect('This is a language recognition example').then((result) => {
  console.log(result);
});

// In an async function
async function testCld() {
  const result = await cld.detect('This is a language recognition example');
  console.log(result);
}

Advanced

const cld = require('cld');
const text     = 'Това е пример за разпознаване на Български език';
const options  = {
  isHTML       : false,
  languageHint : 'BULGARIAN',
  encodingHint : 'ISO_8859_5',
  tldHint      : 'bg',
  httpHint     : 'bg'
};

// As a promise
cld.detect(text, options).then((result) => {
  console.log(result);
});

// In an async function
async function testCld() {
  const result = await cld.detect(text, options);
  console.log(result);
}

Legacy

Detect can be called leveraging the node callback pattern. If options are provided, the third parameter should be the callback.

const cld = require('cld');

cld.detect('This is a language recognition example', (err, result) => {
  console.log(result);
});

Options

isHTML

Set to true if the string contains HTML tags

languageHint

Pass a LANGUAGES key or value as a hint

encodingHint

Pass an ENCODINGS value as a hint

tldHint

Pass top level domain as a hint

httpHint

Pass an HTTP "Content-Encoding" value as a hint

Warning

Once the module has been installed, the underlying C sources will remain in the deps/cld folder and continue to occupy considerable space. This is because they will be required if you ever need to run npm rebuild. If you are under severe constraints you can delete this folder and reclam >100M
