Laravel 5.4 proper way to store Locale setLocale()

Question

I need to know. What is the proper way to store Locale for user. If for each users' request I change the language by

    App::setLocale($newLocale);

Would not it change language for my whole project and for other requests as well? I mean when one user changes language it will be used as default for other users.

Thanks in advance

If you set App::setLocale() in for example in your AppServiceProvider.php, it would change for all the users.

You could create a middleware for this. Something like:

<?php

namespace App\Http\Middleware;

use Closure;

class SetLocale
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        app()->setLocale($request->user()->getLocale());

        return $next($request);
    }
}

(You need to create a getLocale() method on the User model for this to work.)

And then in your Kernel.php create a middleware group for auth:

'auth' => [
    \Illuminate\Auth\Middleware\Authenticate::class,
    \App\Http\Middleware\SetLocale::class,
],

And remove the auth from the $routeMiddleware array (in your Kernel.php).

Now on every route that uses the auth middleware, you will set the Locale of your Laravel application for each user.
