AngularJS Translations, powered by Symfony2

Integrates BazingaJS Translation bundle with AngularJS.

When integrating an Angular application with Symfony2, you can quickly find yourself in an awkward situation when it comes to dealing with translations.

You have all of your translations server-side and exposed to your JS using the excellent Bazinga JS Translations Bundle, but how do you access those translations from your Angular app (including your view partials)?

This Angular module provides functionality to access translations exposed by the above mentioned Symfony2 bundle from within your Angular app.

Key points:

• Works with both 1.x and 2.x versions of the Bazinga JS Translation bundle.
• Provides trans and transChoice filters with the same method signatures as the methods provided by the BazingaJS bundle.
• Uses an adapter so you can use 2.x syntax regardless of whether you're using 1.x or 2.x.

Installation

• bower install --save angular-symfony-translation or
• npm install --save angular-symfony-translation

Include dist/angular-symfony-translation.js before your Angular app (either as a <script> tag or as part of your build script).

List the module as a dependency of your app:

angular.module('myApplication', ['boxuk.translation']);

Usage

The following assumes you already have Bazinga JS Translations Bundle setup and working.

This module exposes an API that matches what is provided by version 2.x of the BazingaJS bundle. If you're using a 1.x release, you can still use this module with no further modifications as the module will handle transforming method calls for the older API.

General documentation:

The filters provided by this module match the BazingaJS bundle as closely as possible. As such, the documentation provided by that bundle should be consulted for more detail on usage, e.g. parameters, pluralization, etc.

This documentation will cover the differences in usage and nothing else.

In a view partial:

trans filter:

<!-- Basic usage -->
<p>{{ 'key' | trans }}</p>
 
<!-- With custom params and domain -->
<p>{{ 'key' | trans: { 'foo': 'bar' }: 'my_domain' }}</p>

transChoice filter:

# app/Resources/messages.en.yml 
salmon: "{0} No salmon today, sorry.|{1} We have a single salmon!|[1,Inf] Woah, there's %count% salmon. That's a lot of salmon."

<!-- Basic usage -->
<p>{{ 'salmon' | transChoice: 5: {'count': 5} }}</p>
 
<!-- With custom domain -->
<p>{{ 'salmon' | transChoice: 5: {'count': 5}: 'my_domain' }}</p>

TranslationService:

Both of the above filters make use of the translation service, which either directly exposes the Translator object from the BazingaJS Translation bundle (for version 2.x of the bundle) or exposes a 2.x to 1.x adapter.

Exposes the same interface as the 2.x version of the bundle: see the bundle documentation for more details.

  var message = TranslationService.transChoice('number_of_dogs', dogs.length);
}
