One app multiple view routes (and domains assigned to it)

Hi, I'm going to build an application thats using multiple domains. Each domain has its own views, but its all the same application.

Api gets json
site1 gets his views
site2 gets other views

I've tried this setup in my routes.php:

<?php

/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.
|

Route::get('/', function () {
    return view('welcome');
});

Route::auth();

//**********************

Route::get('home', 'HomeController@index');
Route::get('api', 'HomeController@index');

Route::get('site2', 'HomeController@index');

//**********************

//**********************
//
// API

Route::get('product', 'HomeController@index'); //returns login or welcome text

    $product = \App\Product::with('category','supplier')->find($id);
    return response(view('product',array('product'=>$product)),200, ['Content-Type' => 'application/json']);
});
//

Route::get('site1/product', function () { // returns all products as view, styled as site1
    $products = \App\Product::all();
    return response(view('site1/products',array('products'=>$products)),200);

    $product = \App\Supplier::with('product')->find($id);
    return response(view('site2/supplier',array('supplier'=>$supplier)),200);
});

It works, but:

I think it can be done better / simpler
How can i connect domains to an in app route like /site1 in apache via htacces or httpd/vhost?

If that's not possible, maybe its better to create a middleware for it to regognise the way its requested and not duplicating the routes for each site?

PS: The answer of @thefuzzy0ne looks like a better way than mine. I'm still thinking about the other way's of @dylanh too and let all the possible way's to do it pass my thoughts, but for now this one is the real answer on my initial question ;)

Or better yet: (Still untested):

function viewForDomain($view, $data = [], $mergeData = [])
{
    $domain = str_replace('.', '_', url());
    return view($domain.'.'.$view, $data, $mergeData);
}

Now you don't have to specify the domain at all, the function will use it automatically. You can still use the standard view() helper when you just want a normal view.

=============================================================

edit from Bart:

i made it working with this one as helper (multiple ways to make helpers, google for that) and added a fallback, so you can make base views and overrule them per domain:

<?php
function viewForDomain($view, $data = [], $mergeData = [])
{
    $domain = str_replace('.', '_', str_replace('http://', '', url('/')));
    if (view()->exists($domain.'.'.$view)) {
        return view($domain.'.'.$view, $data, $mergeData);
    }
    else{
        return view('base.'.$view, $data, $mergeData);
    }
}
?>
