  1. Create a custom module: If you haven’t already done so, create a custom module in Drupal 10. You can refer to the previous question for a step-by-step guide on creating a custom module.<\/li>\n
  2. Define the routing file: In the module folder, create a new file with the extension “.routing.yml”. This file defines your module’s page’s URL path and corresponding controller. For example, if you want to create a controller for the path “\/ttn-hello-world”, your routing file would look like this:<\/li>\n<\/ol>\n
    \n
    custom_module.ttn_hello_world:\r\npath: '\/ttn-hello-world'\r\ndefaults:\r\n_controller: '\\Drupal\\custom_module\\Controller\\TTNHelloWorldController::content'\r\n_title: 'TTN Hello, World!'\r\nrequirements:\r\n_permission: 'access content'\r\n\r\nIn this example, the \"custom_module.ttn_hello_world\" route maps to the \"TTNHelloWorldController::content\" controller, which we'll define in the next step. The \"_title\" parameter sets the page title, and the \"_permission\" parameter restricts access to users with the \"access content\" permission.<\/pre>\n<\/blockquote>\n
      \n
    1. Create the controller class: In the module folder, create a new file with the extension “.php” in the “src\/Controller” directory. This file defines the controller class for your page. For example, if you want to create a controller for the path “\/ttn-hello-world”, your controller class would look like this:<\/li>\n<\/ol>\n
      \n
      <?php\r\n\r\nnamespace Drupal\\custom_module\\Controller;\r\n\r\nuse Drupal\\Core\\Controller\\ControllerBase;\r\n\r\nclass TTNHelloWorldController extends ControllerBase {\r\n\r\n\/**\r\n* Returns the page content.\r\n*\/\r\npublic function content() {\r\n$output = [\r\n'#markup' => $this->t('TTN Hello, World!'),\r\n];\r\nreturn $output;\r\n}\r\n\r\n}<\/pre>\n<\/blockquote>\n
      Now clear cache and access page : \/ttn-hello-world<\/p>\n
