Configuration
=============

Datasette offers several ways to configure your Datasette instances: server settings, plugin configuration, authentication, and more.

To facilitate this, You can provide a ``datasette.yaml`` configuration file to datasette with the ``--config``/ ``-c`` flag:

.. code-block:: bash

    datasette mydatabase.db --config datasette.yaml

.. _configuration_reference:

``datasette.yaml`` Reference
----------------------------

Here's a full example of all the valid configuration options that can exist inside ``datasette.yaml``.

.. _configuration_reference_settings:
Settings configuration
~~~~~~~~~~~~~~~~~~~~~~

:ref:`settings` can be configured in ``datasette.yaml`` with the ``settings`` key.

.. [[[cog
    from metadata_doc import config_example
    import textwrap
    config_example(cog, textwrap.dedent(
      """
        # inside datasette.yaml

        """).strip()
      )

          }
        }
.. [[[end]]]

.. _configuration_reference_plugins:
Plugin configuration
~~~~~~~~~~~~~~~~~~~~

Configuration for plugins can be defined inside ``datasette.yaml``. For top-level plugin configuration, use the ``plugins`` key.

.. [[[cog
    from metadata_doc import config_example
    import textwrap
    config_example(cog, textwrap.dedent(
      """
        # inside datasette.yaml

            key: my_value
        """).strip()
      )
.. ]]]

.. tab:: datasette.yaml

    .. code-block:: yaml

        # inside datasette.yaml
        plugins:
          datasette-my-plugin:
            key: my_value

.. tab:: datasette.json

    .. code-block:: json

        {
          "plugins": {
            "datasette-my-plugin": {
              "key": "my_value"
            }
          }
        }
.. [[[end]]]

For database level or table level plugin configuration, nest it under the appropriate place under ``databases``.

.. [[[cog
