Here the example :

Quick Fix [ PHP ]:

Add to https://github.com/cretueusebiu/laravel-vue-spa/blob/master/resources/views/index.blade.php

@php
$config = [
    'appName' => config('app.name'),
    'locale' => $locale = app()->getLocale(),
    'locales' => config('app.locales'),
    'githubAuth' => config('services.github.client_id'),
];

if ( isset ( $_COOKIE['locale'] ) AND ! array_key_exists( $_COOKIE['locale'] ,  $config['locales'] ) ) {
    setcookie ( 'locale', $config['locale'], time() + ( 86400 ), "/");
}
@endphp
