DeepPartial

Recursive variant of TypeScript's `Partial<T>` — every property at every depth becomes optional.

Usage

import type { DeepPartial } from '@maz-ui/utils'

interface UserSettings {
  notifications: {
    email: boolean
    push: boolean
  }
  theme: {
    primary: string
    secondary: string
  }
}

const update: DeepPartial<UserSettings> = {
  notifications: { email: false },
}

API

type DeepPartial<T> = T extends object
  ? { [P in keyof T]?: DeepPartial<T[P]> }
  : T

Notes

• Primitives (string, number, boolean, null, undefined, …) are returned unchanged.
• Useful for partial-update payloads (PATCH requests, merge functions, default-options patterns).
