Typescript: constants in an interface

Question

How do I place a constant in an Interface in typescript. Like in java it is:

interface OlympicMedal {
  static final String GOLD = \"Gold\";
  static final S         


        

Answer 1

Just use the value in the interface in place of the type, see below

export interface TypeX {
    "pk": "fixed"
}

let x1 : TypeX = {
    "pk":"fixed" // this is ok
}

let x2 : TypeX = {
    "pk":"something else" // error TS2322: Type '"something else"' is not assignable to type '"fixed"'.
}
