Get keys of a Typescript interface as array of strings

Question

I\'ve a lot of tables in Lovefield and their respective Interfaces for what columns they have.
Example:

export interface IMyTable {
  id: number;
  t         


        

Answer 1

The following requires you to list the keys on your own, but at least TypeScript will enforce IUserProfile and IUserProfileKeys have the exact same keys (Required was added in TypeScript 2.8):

export interface IUserProfile  {
  id: string;
  name: string;
};
type KeysEnum = { [P in keyof Required]: true };
const IUserProfileKeys: KeysEnum = {
  id: true,
  name: true,
};
