Laravel route works with subdomain in 2 environments - laravel

Question

I'm coding a platform to generate sub-websites.
I have a route like this who works very well in local :
//Website
Route::domain('{slug}.domain.test')->group(function () {
Route::get('/','WebsitesController#show')->name('web_website_show');
});
I want to be able to make it works as well in production (other domain), so i did :
//Website
Route::domain('{slug}.{domain}')->group(function () {
Route::get('/','WebsitesController#show')->name('web_website_show');
});
And in my template :
Website
The generated URL looks amazing, but the routing doesn't work and bring me to the parent page of the main domain.
What i am doing wrong ?
Thanks

Answer 1

Working with domain routes like this is a little bit of a pain in Laravel.
In an application recently, I parsed the domain part from the application URL and then set it as a configuration value like this:
class AppServiceProvider extends ServiceProvider
{
public function boot()
{
config([
'app.domain' => parse_url(config('app.url'), PHP_URL_HOST),
]);
}
}
You can then use that in your domain routes:
Route::domain('{slug}.'.config('app.domain'), function () {
// Subdomain routes that work in all environments
});

If you are using laravel homestead, you'll need to register every subdomain on the etc/hosts file and on Homestead.yaml, as you probably did with the main domain. Now, I'll recommend the structure:
app.test
subdomain1.app.test
subdomain2.app.test
I wouldn't recommend to use something like:
subdomain1.app1.test
subdomain2.app2.test
I mean, you could, but it doesn't make much sense, and you would also have to register all of this on your Homestead/Local and Production environments.
For the approach that I suggest, you could set up this on an environment variable. https://laravel.com/docs/6.x/configuration#environment-variable-types
You can add any env variable you want/need to the .env file, there's an APP_URL variable, but this includes the http protocol, you could add something like:
APP_DOMAIN=app.test
And for production
APP_DOMAIN=yourapp.com
Then on the routes file access it with the helper method env, you can omit the second parameter, or use it to setup a default value, in case you forget to put it on the .env file.
Route::domain('{slug}.' . env('APP_DOMAIN', 'default.com'))->group(function () {
Route::get('/','WebsitesController#show')->name('web_website_show');
});
BTW, this might be of help for setting up your slug value with named routes:
