Typed Settings

Building on the standard settings features that is a core part of pyApp typed settings provides a more convenient way to define and access settings.

Default settings are defined using a SettingsDef object along with the expected type via type annotations. The settings can then be accessed at runtime using the same definition.

For example settings are defined in the default_settings.py file as:

from pyapp.typed_settings import SettingsDef

class MyAppSettings(SettingsDef):
    MY_CONFIG_VALUE: str = "Foo"

MY_CONFIG_VALUE is added to pyapp.conf.settings just like any other setting and can be overridden by any other settings file.

Where typed settings really shine is using the settings in your application. The SettingsDef object can be imported from the default_settings file and used to access the runtime settings values using the same definition with all the benefits of auto-completion and typing.

from myapp.default_settings import MyAppSettings

print(MyAppSettings.MY_CONFIG_VALUE)
