Laravel Locale Cookie

A Laravel middleware that resolves the application locale from a cookie. The requested value is validated against a configurable list of supported locales and ignored when it is missing or unknown, falling back to a sensible default. Cookie name, supported locales, and fallback locale are all driven by config.

Installation

You can install the package via composer:

composer require jeffersongoncalves/laravel-locale-cookie

You can publish the config file with:

php artisan vendor:publish --tag="locale-cookie-config"

This is the contents of the published config file:

return [
    'cookie' => 'locale',
    'supported' => ['en'],
    'fallback' => null,
];

cookie — the name of the cookie the middleware reads the visitor's locale from (default locale).
supported — the whitelist of accepted locales. A cookie value that is not in this list is ignored.
fallback — the locale applied when the cookie is missing or unsupported. When null, the middleware falls back to the framework's config('app.fallback_locale').

Usage

Register the middleware on the route group that should be locale-aware. The middleware reads the cookie, validates it against your supported list, and applies the matching locale (or the fallback) for the rest of the request:

use JeffersonGoncalves\LocaleCookie\Middleware\SetLocale;

Route::middleware(SetLocale::class)->group(function () {
    // ...locale-aware routes
});

You can also alias it in bootstrap/app.php:

->withMiddleware(function (Middleware $middleware) {
    $middleware->web(append: [
        \JeffersonGoncalves\LocaleCookie\Middleware\SetLocale::class,
    ]);
})

Using with Livewire

If your locale-aware pages use Livewire, register the middleware as a Livewire persistent middleware as well, so subsequent /livewire/update requests keep the visitor's locale instead of falling back to the default. Register both the route-group middleware and the persistent middleware (pattern taken from the source project this package was extracted from):

use Livewire\Livewire;
use JeffersonGoncalves\LocaleCookie\Middleware\SetLocale;

// In a service provider's boot() method
Livewire::addPersistentMiddleware([
    SetLocale::class,
]);
