Handling huge route file

Can you define "huge"? How many lines of code, without comments, etc...?

I guess you can create php files in routes folder then just require them in your web.php file...

Glad it's not just me.

Since L5.3 you can split your routes into files. Since then I have separate route files relating to things like the auth levels and areas of the site. E.g

web.php //public routes
customer.php //customer login
admin.php // staff login

These are mapped in the RouteServiceProvider.php

public function map()
{
        
$this->mapWebRoutes();

$this->mapCustomerRoutes();
        
$this->mapAdminRoutes();

}

// then subsequently you can also add in things like a prefix to apply to all the routes in each file:

protected function mapCustomerRoutes()
{
Route::group([
       'middleware' => 'web',
       'prefix' => 'customer',
       'namespace' => $this->namespace,
        ], function ($router) {
            require base_path('routes/customer.php');
        });
}

It also makes it very clear and easy to do things like apply middleware and pass parameter to a set of routes e.g.

    protected function mapAdminRoutes()
    {
        Route::group([
        // pass admin param to role middleware to check admin privileges
            'middleware' => ['web', 'role:admin' ], 
            'prefix' => 'admin',
            'namespace' => $this->namespace,
        ], function ($router) {
            require base_path('routes/admin.php');
        });
    }
