Field Compose
FieldCompose provides a custom field type that allows you to define multiple sub-fields with a YAML-based configuration. This is useful for grouping related configuration options into a single field, reducing the need for numerous individual fields and database tables.
This module provides a new Field Type which allows defining multiple fields in field settings with YAML based syntax and by respecting exactly the structure of Form and render elements
A good use-case for when to use it is if you have a component with multiple configuration options, e.g: a slider library in which case you can avoid having 10+ addition tables(+revision tables) if you would implement normal fields for this purpose by storing values as JSON.
With this approach, you might a expect slight increase in CPU usage as field values are decoded from JSON but this exactly what you might want as lots of time CPU is underused and DB operations are expensive(especially in a cloud env)
Example configuration bellow
-
id: my_bool
_type: checkbox
_title: Enable something
-
id: my_string_field
_type: textfield
_title: Enter something(State dependent field)
_required: FALSE
_states:
visible:
':input[name="$field_name$[$field_item_delta$][my_bool]"]': { checked: true }
will produce

This module is for simple, multi-fields and is not meant to be a full-on replacement for using entity references, Media or Image fields.
