Introduction
This is an i18next language detection plugin used to detect user language in the browser, with support for:
- cookie (set cookie i18next=LANGUAGE)
- sessionStorage (set key i18nextLng=LANGUAGE)
- localStorage (set key i18nextLng=LANGUAGE)
- navigator (set browser language)
- querystring (append
?lng=LANGUAGEto URL) - htmlTag (add html language tag <html lang="LANGUAGE" ...)
- path (http://my.site.com/LANGUAGE/...)
- subdomain (http://LANGUAGE.site.com/...)
Getting started
Source can be loaded via npm, bower or downloaded from this repo.
# npm package
$ npm install i18next-browser-languagedetector
# bower
$ bower install i18next-browser-languagedetector
- If you don't use a module loader it will be added to
window.i18nextBrowserLanguageDetector
Wiring up:
1import i18next from 'i18next'; 2import LanguageDetector from 'i18next-browser-languagedetector'; 3 4i18next.use(LanguageDetector).init({ 5 supportedLngs: ['de', 'en', 'fr'], 6 ...i18nextOptions 7});
As with all modules you can either pass the constructor function (class) to the i18next.use or to a concrete instance.
supportedLngs is optional, but allows i18next to pick the best match from the list of detected languages. If it's not set then language will be set to the first detected language, regardless of whether your application has translations for that language or not.
Detector Options
The default options can be found here.
1{ 2 // order and from where user language should be detected 3 order: ['querystring', 'cookie', 'localStorage', 'sessionStorage', 'navigator', 'htmlTag', 'path', 'subdomain'], 4 5 // keys or params to lookup language from 6 lookupQuerystring: 'lng', 7 lookupCookie: 'i18next', 8 lookupLocalStorage: 'i18nextLng', 9 lookupSessionStorage: 'i18nextLng', 10 lookupFromPathIndex: 0, 11 lookupFromSubdomainIndex: 0, 12 13 // cache user language on 14 caches: ['localStorage', 'cookie'], 15 excludeCacheFor: ['cimode'], // languages to not persist (cookie, localStorage) 16 17 // optional expiry and domain for set cookie 18 cookieMinutes: 10, 19 cookieDomain: 'myDomain', 20 21 // optional htmlTag with lang attribute, the default is: 22 htmlTag: document.documentElement, 23 24 // optional set cookie options, reference:[MDN Set-Cookie docs](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie) 25 cookieOptions: { path: '/', sameSite: 'strict' }, 26 27 // optional conversion function used to modify the detected language code 28 convertDetectedLanguage: 'Iso15897', 29 convertDetectedLanguage: (lng) => lng.replace('-', '_') 30}
Options can be passed in:
preferred - by setting options.detection in i18next.init:
1import i18next from 'i18next'; 2import LanguageDetector from 'i18next-browser-languagedetector'; 3 4i18next.use(LanguageDetector).init({ 5 detection: options, 6});
on construction:
1import LanguageDetector from 'i18next-browser-languagedetector'; 2const languageDetector = new LanguageDetector(null, options);
via calling init:
1import LanguageDetector from 'i18next-browser-languagedetector'; 2const languageDetector = new LanguageDetector(); 3languageDetector.init(options);
Adding own detection functionality
interface
1export default { 2 name: 'myDetectorsName', 3 4 lookup(options) { 5 // options -> are passed in options 6 return 'en'; 7 }, 8 9 cacheUserLanguage(lng, options) { 10 // options -> are passed in options 11 // lng -> current language, will be called after init and on changeLanguage 12 // store it 13 }, 14};
adding it
1import LanguageDetector from 'i18next-browser-languagedetector'; 2const languageDetector = new LanguageDetector(); 3languageDetector.addDetector(myDetector); 4 5i18next.use(languageDetector).init({ 6 detection: options, 7});
Don't forget: You have to add the name of your detector (myDetectorsName in this case) to the order array in your options object. Without that, your detector won't be used. See the Detector Options section for more.
