Configuration Module
====================

When ``typo3/cms-lowlevel`` is installed, TCA_API registers a provider in the
TYPO3 backend **Configuration** module (:guilabel:`System → Configuration`).
The provider displays all loaded resource definitions as an interactive tree,
which is useful for debugging your setup and verifying that definitions are
loaded and parsed as expected.

What is shown
=============

Each resource definition is listed by its ``resourceName`` and expanded into all
resolved properties. All values reflect the parsed state after ``ApiDefinitionLoader``
has normalised the raw PHP arrays — so what you see is exactly what the extension acts
on at runtime.

.. note::

    The tree is read-only. It reflects the in-memory state after the DI
    container has been warmed up. Clear the TYPO3 caches after changing a
    resource definition file to see the updated values.
