How do you deal with partial types?

Fully typed apps are the correct approach. Let's say your API backend returns a 'full' type (of a Workshop type with 8 fields for example), and, secondly, a list of Workshops but this time only with a 'name' field. In the frontend, you have a 'full view', a 'list of workshops view' (showing only the name of each) and a 'preview view' of a Workshop which uses 3 of its 8 fields. How do you describe these types in the app and at the interfaces between the frontend and backend?How do you deal with partial types?
