This package convert all your localization messages from your Laravel app to JavaScript with a small library to interact with those messages following a very similar syntax you are familiar with.


  • Support Laravel 4.2.x, Laravel 5.0.x, Laravel 5.1.x, Laravel 5.2.x and Laravel 5.3.x.
  • Includes Lang.js (a thin library highly inspired on Laravel's Translator class).
  • Allow to specify desired lang files to be converted to JS.
  • Lang.js API is based on Laravel's Translator class. No need to learn a whole API.


composer require mariuzzo/laravel-js-localization

In your Laravel app go to config/app.php and add the following service provider:



The Laravel-JS-Localization package provides a command that generate the JavaScript version of all your messages found at: app/lang (Laravel 4) or resources/lang (Laravel 5) directory. The resulting JavaScript file will contains all your messages plus Lang.js (a thin library highly inspired on Laravel's Translator class).

Generating JS messages

php artisan lang:js

Specifying a custom target

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

Compressing the JS file

php artisan lang:js -c


First, publish the default package's configuration file running:

php artisan vendor:publish --provider="Mariuzzo\LaravelJsLocalization\LaravelJsLocalizationServiceProvider"

The configuration will be published to config/localization-js.php.

You may edit this file to define the messages you need in your Javascript code. Just edit the messages array in the config file. Empty messages array will include all the language files in build.

To make only pagination.php & validation.php files to be included in build process:


return [
    'messages' => [

Using gulp (optional)

Install gulp-shell and then run it directly in your gulpfile.js:

var shell = require('gulp-shell');

gulp.task('langjs', shell.task('php artisan lang:js -c public/js/messages.js'));

Using Laravel's elixir (optional)

Before Elixir 4.0:

elixir.extend('langjs', function(path) {
    gulp.task('langjs', function() {
        gulp.src('').pipe(shell('php artisan lang:js ' + (path || 'public/js/messages.js')));

    return this.queueTask('langjs');

Elixir 4.0+:

var Task = elixir.Task;
elixir.extend('langjs', function(path) {
    new Task('langjs', function() {
        gulp.src('').pipe(shell('php artisan lang:js ' + (path || 'public/js/messages.js')));

And use it like this:

elixir(function(mix) {
