Type Alias Paths<T, D>

Paths: [D] extends [never]
    ? never
    : T extends object
        ? {
            [K in keyof T]-?: K extends string
            | number
                ? T[K] extends object ? K | Join<K, Paths<T[K], Prev[D]>> : K
                : never
        }[keyof T]
        : ""

Build all nested paths for an object up to a reasonable recursion depth

Type Parameters

T
D extends number = 5

Example

type User = { id: number; profile: { name: string; address: { city: string; zip: number } } };
type UserPaths = Paths<User>;
// "id" | "profile" | "profile.name" | "profile.address" | "profile.address.city" | "profile.address.zip"
