How to redirect all Laravel routes to a new subdomain using Laravel routing system?

Question

Redirect all Laravel routes to the same route, but change the base URL.

I want to move my Laravel project from domain to subdomain What is the best way to redirect all requests on the last domain to the same new subdomain.

For example, if a user sends a request to this URL

mydomain.com/page/1

Redirect to this URL

subdomain.mydomain.com/page/1

I prefer to handle it inside the Laravel project. Not an NGINX configuration.

To handle this at the Laravel level you can use middleware. Middleware provides a convenient mechanism to inspect and filter HTTP requests entering your application.

Here are examples of how you can do this.

First, create a new middleware by running the following command:

php artisan make:middleware SubdomainRedirectMiddleware

Next, open the newly created file app/Http/Middleware/SubdomainRedirectMiddleware.php and add the redirection logic to the handle method:

public function handle(Request $request, Closure $next)
{
    // Replace 'mydomain' with your actual domain
    if ($request->getHost() === 'mydomain.com') {

        // Replace 'subdomain' with your actual subdomain
        return redirect()->to(str_replace('mydomain.com', 'subdomain.mydomain.com', $request->fullUrl()));
    }

    return $next($request);
}

Then, you need to register this middleware. Open app/Http/Kernel.php and add the following lines to the routeMiddleware array:

protected $routeMiddleware = [
    'subdomain.redirect' => \App\Http\Middleware\SubdomainRedirectMiddleware::class,
];

Route::group(['middleware' => 'subdomain.redirect'], function () {
    // All your routes go here
});

Please replace 'mydomain' and 'subdomain' with your actual domain and subdomain in SubdomainRedirectMiddleware.php.
