@ts-types/deep-partial v0.0.1

deep-partial

This package base on TypeScript's built-in Partial<T> type. But allow allowing deep partials to be created.

The current behavior of TypeScript's Partial<T> type means that nested objects will not have the optional status applied to their fields. For example:

type Employee = {
  name: string;
  age: number;
  address: {
    number: number;
    street: string;
  };
};

const myHouseNumber: Partial<Employee> = { address: { number: 52 } };

// The above is invalid, and results in error: Property 'street' is missing in
// type '{ number: number; }' but required in type '{ number: number; street: string; }'.

Using DeepPartial<T> instead makes this assignment possible:

const myHouseNumber: DeepPartial<Employee> = { address: { number: 52 } };

Installation

Just a quick npm install --save-dev @fs-types/deep-partial, or the Yarn equivalent.
