Travis Coveralls npm version Bower David

locizer.js

locizer.js is lightweight client to access data from your locize project and use that inside your application (eg. passing that to polyglot, formatjs).

Getting started

Source can be loaded via npm, bower or downloaded from this repo.

Or load it from the offical npm cdn:

https://unpkg.com/locizer[@version]/locizer[.min].js

<!DOCTYPE html>
<html>
  <head>
    <script src="https://unpkg.com/locizer/locizer.min.js"></script>
    <script>
      locizer
        .init({
          fallbackLng: "en",
          referenceLng: "en",
          projectId: "[your project id]"
        })
        .load("translation", function(err, translations, lng) {
          // feed the translations to formatjs, polyglot,...
        });
    </script>
  </head>
  <body></body>
</html>

Init options

IMPORTANT make sure you do not add your apiKey in the production build to avoid misuse by strangers

{
  lng: 'en', // optional if set we won't detect language of user
  fallbackLng: 'en',
  referenceLng: 'en',

  loadIfTranslatedOver: 0.1, // default 1 - we only load lngs that are fully translated, lower this value to load files from languages that are just partially translated

  projectId: 'c8038fbe-7be8-4f96-9692-943b3333185b',
  apiKey: '27e9ecff-8926-43b0-80fd-e683abe49297', // only needed if you want to add new keys via locizer - remove on production!
  version: 'latest', // version to load from locize
  private: false, // set true if using locize private publish

  // hostnames that are allowed to send last used data
  // please keep those to your local system, staging, test servers (not production)
  allowedHosts: ['localhost'],
  // hostnames that are allowed to add, update keys
  // please keep those to your local system, staging, test servers (not production)
  allowedAddOrUpdateHosts: ['localhost'],

  // language detection options:

  // order and from where user language should be detected
  order: ['querystring', 'cookie', 'localStorage', 'sessionStorage', 'navigator', 'htmlTag'],

  // keys or params to lookup language from
  lookupQuerystring: 'lng',
  lookupCookie: 'i18next',
  lookupLocalStorage: 'i18nextLng',

  // cache user language on
  caches: ['localStorage', 'cookie'],

  // optional expire and domain for set cookie
  cookieMinutes: 10,
  cookieDomain: 'myDomain',

  // optional htmlTag with lang attribute, the default is:
  htmlTag: document.documentElement
}

API

init

locizer.init(options);

getLanguage

// gives the language provided in options or detected from user compared to languages existing in your project (see also init option: loadIfTranslatedOver)
locizer.getLanguage((err, lng) => {));

// if you want the language detected but unfiltered against what your project provided
var loc = locizer.detector.detect();

getLanguages

// gives you all languages supported in your project
locizer.getLanguages((err, lngs) => {));

// something like:
{
  "en": {
    "name": "English",
    "nativeName": "English",
    "translated": {
      "latest": 1
    }
  },

    "translated": {
      "latest": 0.19999999999999998
    }
  }
}

load

// load namespaces from locize in the lng provided in options or detected from user
locizer.load("namespace", (err, res) => {});

// load in different lng
locizer.load("namespace", "de", (err, res) => {});

add

// add a new key
