Livewire

Open the config/livewire.php file and change this:

'middleware_group' => ['web'],

to this:

'middleware_group' => [
    'web',
    'universal',
    InitializeTenancyByDomain::class, // or whatever tenancy middleware you use
],

Now you can use Livewire both in the central app and the tenant app.

Also make sure to enable universal routes.

And if you're using file uploads, read the Real-time facades page of the documentation. Livewire uses real-time facades in the uploading logic.
