Each request to the backend is eventually executed by a controller. A list of routes is defined which maps a given request to a controller and an action.
Routes are defined inside extensions, in file
for general requests and in
Here is an extract of
<?php use TYPO3\CMS\Backend\Controller; /** * Definitions for routes provided by EXT:backend * Contains all "regular" routes for entry points * * Please note that this setup is preliminary until all core use-cases are set up here. * Especially some more properties regarding modules will be added until TYPO3 CMS 7 LTS, and might change. * * Currently the "access" property is only used so no token creation + validation is made, * but will be extended further. */ return [ // Login screen of the TYPO3 Backend 'login' => [ 'path' => '/login', 'access' => 'public', 'target' => Controller\LoginController::class . '::formAction' ], // Main backend rendering setup (previously called backend.php) for the TYPO3 Backend 'main' => [ 'path' => '/main', 'target' => Controller\BackendController::class . '::mainAction' ], ... ];
So a routes file essentially returns an array containing routes mapping.
A route is defined by a key, a path and a target. The “public”
property indicates that no authentication is required for that action.
As the above code extract mentions, routes are a new feature (since TYPO3 CMS 7) and may yet evolve.
