Localized Routes

Sure, so when someone goes to /, you want to detect their preferred language and redirect them to that languages homepage?

Here's what I would do:

# config/routes.yaml
controllers:
    resource:
        path: ../src/Controller/
        namespace: App\Controller
    type: attribute
    trailing_slash_on_root: false
    prefix:
        en: /en
        fr: /fr
        es: /es

# add this
raw_homepage:
    path: /
    controller: App\Controller\RawHomepageController::homepage

Now, create the RawHomepageController:

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\DependencyInjection\Attribute\Autowire;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;

final class RawHomepageController extends AbstractController
{
    public function homepage(
        Request $request,

        #[Autowire(param: 'kernel.enabled_locales')]
        array $enabledLocales,

        #[Autowire(param: 'kernel.default_locale')]
        string $defaultLocale,
    ): Response {
        // find the user's locales that also are in our enabled locales
        $matches = array_intersect($request->getLanguages(), $enabledLocales);
        
        // use the first match - if none, use our default
        $locale = reset($matches) ?: $defaultLocale;

        return $this->redirectToRoute('app_homepage', ['_locale' => $locale]);
    }
}

Now, / is no longer a 404 and you're redirected to /{locale} (or /en by default).

If you have a bunch of controllers you don't want prefixed (maybe your admin section), you can use subdirectories in your src/Controller directory:

# config/routes.yaml
localized_controllers:
    resource:
        path: ../src/Controller/Localized/
        namespace: App\Controller\Localized
    type: attribute
    trailing_slash_on_root: false
    prefix:
        en: /en
        fr: /fr
        es: /es

unlocalized_controllers:
    resource:
        path: ../src/Controller/Unlocalized/
        namespace: App\Controller\Unlocalized
    type: attribute

Now, routes in src/Controller/Localized will be prefixed, and ones in src/Controller/Unlocalized will not.

I hope this helps!

Wow! Thank you so very much Kevin❗️

this helped me a lot! ⛵️

by the way, call me a nitpicker:
In the transcription code example (3:02) the tick marks are missing. Don't they?

I'm glad this helped!

Haha good catch, you're right, I'm missing the quotes in the code block. It isn't technically required (it works just fine without), but YAML has made syntax changes in the past that require certain text to be wrapped in quotes. Best to use quotes when possible.
