react-fluxible-i18n

Simple i18n translation and localization components and helpers for React+Fluxible applications.

Note: If you are not using Fluxible, you can use react-i18nify instead. If you are using Redux, you can use react-redux-i18n instead.

Preparation

First install the package:

npm i react-fluxible-i18n --save

Secondly, register the I18nStore in your app:

var Fluxible = require('fluxible');
var I18nStore = require('react-fluxible-i18n').I18nStore;

const app = new Fluxible({
  // ...
});

app.registerStore(I18nStore);

Finally, set the translations and locales to be used, by dispatching events:

context.dispatch('SET_TRANSLATIONS', {
  en: {
    application: {
      title: 'Awesome app with i18n!',
      hello: 'Hello, %{name}!'
    },
    date: {
      long: 'MMMM Do, YYYY'
    },
    export: 'Export %{count} items',
    export_0: 'Nothing to export',
    export_1: 'Export %{count} item',
    two_lines: 'Line 1<br />Line 2'
  },
  nl: {
    application: {
      title: 'Toffe app met i18n!',
      hello: 'Hallo, %{name}!'
    },
    date: {
      long: 'D MMMM YYYY'
    },
    export: 'Exporteer %{count} dingen',
    export_0: 'Niks te exporteren',
    export_1: 'Exporteer %{count} ding',
    two_lines: 'Regel 1<br />Regel 2'
  }
});

context.dispatch('SET_LOCALE', 'nl');

Now you're all set up to start unleashing the power of react-fluxible-i18n!

Components

The easiest way to translate or localize in your React components is by using the Translate and Localize components:

var React = require('react');
var Translate = require('react-fluxible-i18n').Translate;
var Localize = require('react-fluxible-i18n').Localize;

var AwesomeComponent = React.createClass({
  render: function() {
    return (
      <div>
        <Translate value="application.title"/>
          // => returns '<span>Toffe app met i18n!</span>' for locale 'nl'
        <Translate value="application.title" style={{ fontWeight: 'bold', fontSize: '14px' }} />
        // => returns '<span style="font-weight:bold;font-size:14px;">Toffe app met i18n!</span>' for locale 'nl'
        <Translate value="application.hello" name="Aad"/>
          // => returns '<span>Hallo, Aad!</span>' for locale 'nl'
        <Localize value="2015-09-03" dateFormat="date.long"/>
          // => returns '<span>3 september 2015</span> for locale 'nl'
        <Localize value={10/3} options={{style: 'currency', currency: 'EUR', minimumFractionDigits: 2, maximumFractionDigits: 2}}/>
          // => returns '<span>€ 3,33</span> for locale 'nl'
        <Translate value="export" count={1} />
          // => returns '<span>Exporteer 1 ding</span> for locale 'nl'
        <Translate value="export" count={2} />
          // => returns '<span>Exporteer 2 dingen</span> for locale 'nl'
        <Translate value="two_lines" dangerousHTML />
          // => returns '<span>Regel 1<br />Regel 2</span>'
      </div>
    );
  }
});

Helpers

If for some reason, you cannot use the components, you can use the I18n.t and I18n.l helpers instead:

var I18n = require('react-fluxible-i18n').I18n;

I18n.t('application.title'); // => returns 'Toffe app met i18n!' for locale 'nl'
I18n.t('application.hello', {name: 'Aad'}); // => returns 'Hallo, Aad!' for locale 'nl'
I18n.t('export', {count: 0}); // => returns 'Niks te exporteren' for locale 'nl'
I18n.t('application.weird_key'); // => returns 'Weird key' as translation is missing
I18n.t('application', {name: 'Aad'}); // => returns {hello: "Hallo, Aad!", title: "Toffe app met i18n!"} for locale 'nl'

I18n.l(1385856000000, { dateFormat: 'date.long' }); // => returns '1 december 2013' for locale 'nl'
I18n.l(Math.PI, { maximumFractionDigits: 2 }); // => returns '3,14' for locale 'nl'

Supported localize options

The localize component and helper support all date formatting options as provided by the Javascript moment library. For the full list of options, see http://momentjs.com/docs/#/displaying/format/.

For number formatting, the localize component and helper support all options as provided by the Javascript built-in Intl.NumberFormat object. For the full list of options, see https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/NumberFormat.
