  Overview A routeis a path which is defined for Drupal to return some sort of content on. For example, the default front page, '/node' is a route. When Drupal receives a request, it tries to match the requested path to a route it knows about. If the route is found, then the route's definition is used to return content. Otherwise, Drupal returns a 404.

  Routing in Drupal7 ● In Drupal 7 routing is handled by hook_menu(). ● Apart from just routing it has many other responsibilities to do ➢ Routing ➢ Access Control ➢ Visible navigation ➢ File uploading ● It is too much for a single function to handle and apart from routing many other tasks are tightly coupled in a single function. ● And this looks a bit alien concept to developers from other MVC frameworks.

  Routing in Drupal8 ● Drupal's routing system works with the Symfony HTTP Kernel. ● Rather than defining routes in hook_menu(), they are now defined in module.routing.yml files, in YAML format ● An example from node.routing.yml file entity.node.edit_form: path: '/node/{node}/edit' defaults: _entity_form: 'node.edit' requirements: _entity_access: 'node.update' options: _node_operation_route: TRUE
