Transforming data objects into simplified interfaces using Typescript

Issue Explanation

Current data:

{
  "field1": "value",
  "field2": 3,
  "field3": true,
  "extraField": "toRemove"
}

An interface is defined as follows:

export interface MyInterface {
  field1: string;
  field2: number;
  field3: boolean;
}

Objective

I am in need of converting or casting my current data to match the MyInterface (with the removal of extraField)

Avoid the Solutions Below

  • Avoid deleting myData.extraField;
  • Avoid using the .map() operator

Answer №1

const NewType = Skip<typeof initialObject, "additionalProperty">;

Skip alias is documented in the TypeScript 2.8 release notes.
