Implementing Ember.js Internationalization Features

Ember.js provides a built-in internationalization (i18n) feature that allows developers to easily translate their applications into multiple languages. In this article, we will explore how to implement Ember.js internationalization features in your application.

Setting Up Ember.js Internationalization

To set up Ember.js internationalization, you need to install the `ember-i18n` addon. You can do this by running the following command in your terminal:

ember install ember-i18n

Once the installation is complete, you need to configure the `ember-i18n` addon in your Ember.js application. You can do this by creating a new file called `config/environment.js` and adding the following code:

module.exports = function(environment) {
  var ENV = {
    // ...
    i18n: {
      defaultLocale: 'en'
    }
  };
  // ...
  return ENV;
};

Defining Translations

To define translations in your Ember.js application, you need to create a new file called `config/locales/en/translations.js` and add the following code:

export default {
  'hello.world': 'Hello World',
  'goodbye.world': 'Goodbye World'
};

This code defines two translations: `hello.world` and `goodbye.world`. You can add more translations as needed.

Using Translations in Your Application

To use translations in your Ember.js application, you need to use the `t` helper provided by the `ember-i18n` addon. You can use the `t` helper in your templates like this:

{{t 'hello.world'}}

This code will render the translation for `hello.world` in your template.

Switching Between Locales

To switch between locales in your Ember.js application, you need to use the `setLocale` method provided by the `ember-i18n` addon. You can use the `setLocale` method like this:

import Ember from 'ember';

export default Ember.Controller.extend({
  actions: {
    switchToFrench() {
      this.set('i18n.locale', 'fr');
    }
  }
});

This code sets the locale to French when the `switchToFrench` action is triggered.

Pluralization and Formatting

The `ember-i18n` addon also provides support for pluralization and formatting. You can use the `t` helper with pluralization and formatting options like this:

{{t 'hello.world' count=2}}

This code will render the translation for `hello.world` with the correct pluralization for the count of 2.

Using the `format` Option

You can also use the `format` option to format the translation. For example:

{{t 'hello.world' format='uppercase'}}

This code will render the translation for `hello.world` in uppercase.
