How to Structure Types for a Restaurant Menu in a Database?

Typically, you’d want to have application-wide types that don’t strictly reflect your database schema. Although they often align, it’s beneficial to keep them separate to prevent issues during refactoring. Start by defining the essential types for your business logic, then create composite types for your detailed menus as needed. This separation allows your application and the database to evolve independently, which is key for scalable applications!

One thing to keep in mind is how the types will be utilized. For instance, your list page might require just the basic `Menu` type while the editor needs the complete structure. Define your types based on what each view uses instead of what the database provides directly. Additionally, it's smart to keep your inferred types as the 'row' types while creating separate API response types like `MenuDetail` for better clarity and organization in your code.

I've faced this same dilemma! Here’s what has worked for me: keep `Menu` as your basic database row type and use `MenuWithCategories` or `MenuTree` for the nested version. I like to think of it in terms of depth levels—`Menu` is depth 0, `MenuWithCategories` adds depth 1, and if you ever need to include items too, then consider using `MenuFull` or `MenuWithCategoriesAndItems`. You can even define nested types as extensions for cleaner code!

Your naming seems alright to me! I'd suggest creating a response type that includes all necessary details, perhaps naming it `FullMenuResponse`. This would encapsulate the menu along with its related data. Just a note: it’s usually better to make API types less dependent on the database structure to avoid tight coupling. This way, changes in the database won't break your API. Just something to ponder!

You could stick with the `Menu` name for the basic type and then call your comprehensive type something like `MenuWithContents` or `FullMenu`. If you want a simpler approach, you could rename your existing `Menu` to `BaseMenu`. This way, it’s clear and intuitive!

Consider calling the nested version `MenuWithItems` or `MenuFull`, while keeping `Menu` for the base type. If you want to get a bit creative, `MenuExpanded` could also work. Just go with what feels intuitive!
