Laravel 5.2 Laravel 5.1 Laravel 5.0 Laravel 4.2 Latest Stable Version Total Downloads License

This is a simple package that convert all your localization messages of your Laravel app to JavaScript, and provides a small JavaScript library to interact with those messages.

Support Laravel 4.2.x, Laravel 5, Laravel 5.1.x. and Laravel 5.2.x.


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

"mariuzzo/laravel-js-localization": "1.2.*"


composer update

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

'providers' => [
    // ...
    // ...

That's it!


This project comes with a command that generate the JavaScript version of all your messages found at: app/lang or 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

Compressing the JS file

php artisan lang:js -c

Use gulp to publish (optional):

Install gulp-shell from with npm install --save-dev 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'));

or you can extend Laravel's elixir like this:

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');

And use it like this:

elixir(function(mix) {




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

Getting a message


Getting a message with replacements

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

Checking if a message key exists


Support for singular and plural message based on a count

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