Laravel - Routing - Subdomain Routing

Route groups may also be used to handle subdomain routing. Subdomains may be assigned route parameters just like route URIs, allowing you to capture a portion of the subdomain for usage in your route or controller. The subdomain may be specified by calling the domain method before defining the group:

Route::domain('{account}')->group(function () {
    Route::get('user/{id}', function ($account, $id) {
In order to ensure your subdomain routes are reachable, you should register subdomain routes before registering root domain routes. This will prevent root domain routes from overwriting subdomain routes which have the same URI path.
