internationalisation (i18n) with javascript (jquery) the easy way

Introduction

Project goal is to provide a easy way to translate a website on clientside:

• fetch resources from server
• fetch each resource file individual (static) or all once via dynamicRoute
• apply translation to html tags with attribute data-i18n
• post missing key-value pairs to server (for easy development -> just translate the new keys)
• search for key en-US first, than in en, than in fallback language (or de-DE, de , fallback)

Usage

Assuming we loaded en-US, en and dev resources for two namespaces ('ns.special' and 'ns.common'):

// given loaded and merged dictionaries in i18next.js to:
{
  "en_US": {
    "ns.special": {
      "app": {
        "name": "i18n"
        "insert": "you are __youAre__",
        "child": "__count__ child",
        "child_plural": "__count__ children"
      }
    },
    "ns.common": {}
  },
  "en": {
    "ns.special": {
      "app": {
        "area": "Area 51"
      }
    },
    "ns.common": {}
  },
  "dev": {
    "ns.common": {
      "app": {
        "company": {
          "name": "my company"
        }
      },
      "add": "add"
    },
    "ns.special": {
    	"nav": {
    	  "home": "home",
          "1": "link1",
    	  "2": "link2"
    	}
    }
  }
}

you can translate using $.t(key, [options])

$.i18n.init({
    lng: 'en-US',
    ns: { namespaces: ['ns.common', 'ns.special'], defaultNs: 'ns.special'}
}, function() {
    $.t('app.name'); // -> i18n (from en-US resourcefile)
    $.t('app.area'); // -> Area 51 (from en resourcefile)
    $.t('ns.common:app.company.name'); // -> my company (from dev resourcefile)
    $.t('ns.common:add'); // -> add (from dev resourcefile)
});

insert values into your translation

$.t('app.insert', {youAre: 'great'}) // -> you are great

support for plurals

$.t('app.child', {count: 1}) // -> 1 child
$.t('app.child', {count: 3}) // -> 3 children

or you can just $('.mySelector').i18n() assuming you have added attribute data-i18n="key" to your elements

// given
<ul class="nav">
	<li class="active"><a href="#" data-i18n="nav.home">home</a></li>
	<li><a href="#" data-i18n="nav.1">link1</a></li>
	<li><a href="#" data-i18n="nav.2">link2</a></li>
</ul>

// just do to translate all elements having attribute _data-i18n_
$.i18n.init({
    lng: 'en-US',
    ns: { namespaces: ['ns.common', 'ns.special'], defaultNs: 'ns.special'}
}, function() {
    $('.nav').i18n();
});

For missing keys (if option addMissing is set to true) will be send to server with actual text as defaultValue.

Sample usage

In the folder you find one static sample.

serverside integrations

i18next-node is bringing i18next to node.js
