Examples

Basic Usage

import type { LoosePartial } from 'uni-types'

interface User {
  id: number
  name: string
  email: string
}

type PartialUser = LoosePartial<User>
// { id?: number; name?: string; email?: string }

const user: PartialUser = {
  name: 'John'
  // id and email can be omitted
}

With Update Functions

function updateUser(id: number, updates: LoosePartial<User>) {
  // Only update provided fields
}

updateUser(1, { name: 'Jane' })
updateUser(2, { email: 'jane@example.com', name: 'Jane' })
