Type alias DeepToPrimitive<T>

Recursively transforms an object type T into a type where all properties are replaced with their corresponding primitive types.

Returns

A new object type with primitive types.

Example

type Actual = {
  a: 'a';
  b: 85;
  c: true;
  d: {
    e: 'xxxxxxxxxxx';
    f: 'eeeeeeeeeeeeeeeeee';
    g: {
      h: 1000000000000000;
      i: undefined;
      j: null;
    };
  };
};

type Expected = {
  a: string;
  b: number;
  c: boolean;
  d: {
    e: string;
    f: string;
    g: {
      h: number;
      i: undefined;
      j: null;
    };
  };
};

type Result = DeepToPrimitive<Actual>; // Result: Expected
