Laravel different 404 pages for different namespaces/route-groups - php

Question

I have three different Http namespaces in Laravel: Frontend, Backend, and API. There is also a different namespace for each route group. Here is an example code (frontend route group) from RouteServiceProvider:
protected function mapFrontendRoutes(Router $router) {
$router->group([
'namespace' => 'App\Http\Controllers\Frontend',
'middleware' => 'web',
], function ($router) {
require app_path('Http/Routes/frontend.php');
});
}
Now, I want to setup three different 404 pages for these namespaces/route groups:
API - show 404 response in JSON format
Frontend - errors/404.blade.php
Backend - have a separate view in backend/errors/404.blade.php
How can I create these? I have been searching the web and have come across nothing regarding this.
Laravel version: 5.2

You can achieve that by overriding (add) renderHttpException method in App\Exceptions\Handler. The method receives the HttpException as parameter and returns a response.
Something like this:
protected function renderHttpException(HttpException $e) {
$status = $e->getStatusCode();
if (Request::ajax() || Request::wantsJson()) {
return response()->json([], $status);
} else if(Request::is('/backend/*')) { //Chane to your backend your !
return response()->view("backend/errors.{$status}", ['exception' => $e], $status, $e->getHeaders());
}else {
return response()->view("errors.{$status}", ['exception' => $e], $status, $e->getHeaders());
}
}
