Database driven urls

In CI3 I use following code in routes.php:

PHP Code:

require_once( BASEPATH .'database/DB'. EXT );
$db =& DB();
$url = trim($_SERVER['REQUEST_URI'],'/');

$query_res = $db->query("SELECT * FROM `routes` where name = ?");
$row = $query_res->row();
if(isset($row)){
    $route[$url] = $row->path;
} 


for database driven routes.
How can I store routes in DB in CI4?
I want use routes like http://site.com/route1 for different controllers
