About ISO 639 Macrolanguage

ISO 639 is a set of international standards that lists short codes for language names. The ISO 639-1 and ISO 639-2 codes are primarily used, and these codes cover the majority of languages in the world. This package uses ISO 639 macrolanguages to ensure comprehensive and accurate representation of languages.

For more information about ISO 639 macrolanguage, visit the Wikipedia page.

Preview in Action:

Using custom toggle button

You can use your own custom toggle button by passing defaultToggleBtn prop as false and rendering the select container with reference to your custom button. Here's an example: Easy peasy!

1import React, { useRef } from 'react';
2import { RiTranslateAi2 } from "react-icons/ri";
3import LanguageSelector from 'react-language-selector-lite';
4
5const App = () => {
6  const customButtonRef = useRef(null);
7
8  const handleLanguageSelect = (language) => {
9    console.log('Selected language:', language);
10    // {1: 'de', 2: 'deu', 3: 'deu', name: 'German', local: 'Deutsch', 2T: 'deu', 2B: 'ger'}
11  };
12
13  return (
14    <div className="relative w-full">
15      <button ref={customButtonRef}>
16        <RiTranslateAi2 className="size-6" />
17      </button>
18      <LanguageSelector
19        onSelect={(value) => handleLanguageSelect(value)}
20        theme="dark"
21        includeDetails={true}
22        defaultToggleBtn={false}
23        buttonRef={customButtonRef}
24      />
25    </div>
26  );
27};
28
29export default App;

Limiting Language Options

You can limit the available options by passing an array of language codes to the options prop:

1<LanguageSelector
2  onSelect={handleLanguageSelect}
3  options={['en', 'es', 'fr']}
4/>
