This module adds GraphQL support for FieldtypeMapMarker. It is only intended for use with ProcessGraphQL module.
ProcessGraphQL comes with support for almost all core ProcessWire fieldtypes. However that might be not enough for everyone. Luckily there is a way to add support for your desired fieldtypes via third-party modules. This module is an example for that. ProcessGraphQL does not support FieldtypeMapMarker out of the box. But once you install this module it seamlessly adds support for FieldtypeMapMarker.
This module's files should be placed in /site/modules/GraphQLFieldtypeMapMarker/ How to install or uninstall modules
Everything works behind the scenes for this module. After you installed it, FieldtypeMapMarker fields will be available in your GraphQL api.
To learn about how you can create your own GraphQL extension modules for ProcessWire see documentation at ProcessGraphQL's github repository.
