When working with field masks, checks usually happen at run-time and through tests. After some work, I figured out how to take advantage of TypeScript’s type system, so one can also leverage compile-time checks. I wrote two snippets to showcase it: The first one retrieves only top-level fields of a structure (goto implementation) let data = getPartialData(['id', 'settings']) // data contains ONLY `id` and `settings` fields The second one fetches fields at a specified depth within a structure (goto implementation).
