Laravel JS Lang Converter

Laravel Localization in JavaScript.

Laravel JS Lang Converter converts all your localization messages of your Laravel app to JavaScript, providing a small JavaScript library to interact with those messages in the fron end.

Most of the work has been developed in Mariuzzo's package

Laravel 5.5+ is supported. PHP 7.0 is required. For Laravel 5.1 - 5-4 versions, use the v2.x branch.

Installation

Add the following line to you composer.json file under require.

"michele-angioni/laravel-js-lang-converter": "~3.0"

and run composer update or composer install.

Then you need to add the Laravel JS Lang Converter service provider in your app/config/app.php file

'providers' => [
    // ...
    'MicheleAngioni\LaravelJsLangConverter\LaravelJsLangConverterServiceProvider',
    // ...
],

In order to use some package features, you need to publish the config file through the artisan command php artisan vendor:publish. It will create the laravel_js_lang.php file in your config directory.

Now you are done!

Usage

This project comes with a command that generate the JavaScript version of all your messages found in resources/lang directory. The resulting JavaScript file will have the whole bunch of messages and a thin library similar to Laravel's Lang class.

Generating JS messages

php artisan lang:js

Specifying a custom target

php artisan lang:js public/assets/dist/lang.dist.js

Converting only some files

If you don't want to convert ALL your lang files, you can specify the files you want to be converted into your laravel_js_lang.php conf file. Under the files array, just add the list of your source files, like so:

'files' => [
    'pagination',
    'validation'
]

Compressing the JS file

php artisan lang:js -c

Use gulp to publish (optional):

1. Install gulp-shell from https://github.com/sun-zheng-an/gulp-shell with npm install --save-dev gulp-shell .

2. Create an extension for elixir in your gulpfile.js:

   var shell = require('gulp-shell');
   
   //......
   
   var Task = elixir.Task;
   
   elixir.extend('langjs', function(path, minimize) {
       new Task('langjs', function() {
           var command = "php artisan lang:js " + (path || "public/js/messages.js");
               if (minimize) {
                   command += " -c";
               }
           return gulp.src("").pipe(shell(command));
       });
   });
   
   gulp.task('langJs', shell.task('php artisan lang:js -c public/js/messages.js'));
   

3. Use the new elixir task:

elixir(function(mix) {
    var path = "public/js";
    var minimize = true;
    mix.langjs(path, minimize);
});

Documentation

This is the documentation regarding the thin JavaScript library. The library is highly inspired on Laravel's Lang class.

Getting a message

Lang.get('messages.home');

Getting a message with replacements

Lang.get('messages.welcome', { name: 'Joe' });

Changing the locale

Lang.setLocale('es');

Checking if a message key exists

Lang.has('messages.foo');

Support for singular and plural message based on a count

Lang.choice('messages.apples', 10);

Calling the choice method with replacements

Lang.choice('messages.apples', 10, { name: 'Joe' });

For more detailed information, take a look at the source: Lang.js.
