Iterate over interface properties in TypeScript

Question

I need to map interface properties to objects:

interface Activity {
  id: string,
  title: string,
  body: string,
  js         


        

Answer 1

If you are okay with having it added during a compile time and you are using TypeScript >= 2.4.1, you can try the way proposed here.

Basically, you should add the ts-transformer-keys dependency, custom transformer, like a basic one and you'll be able to list the properties like this:

import { keys } from 'ts-transformer-keys';

interface Props {
    id: string;
    name: string;
    age: number;
}
const keysOfProps = keys();

console.log(keysOfProps); // ['id', 'name', 'age']
