Convert all existing objects to strings

I have a type that consists of properties with different data types

type ExampleType = {
  one: string
  two: boolean
  three: 'A' | 'Union'
}

Is there an easier way to define the same type but with all properties as strings?

type ExampleStringType = {
  one: string
  two: string
  three: string
}

While looking through the documentation, I came across some intrinsic string manipulation types, but none for converting all properties to string. I believe it should be possible. Perhaps something like this:

const value: AllString<ExampleType> = {
  one: "string"
  two: "string"
  three: "string"
}

Answer №1

If you need to extract keys of a specific type, you can utilize the keyof operator and then convert them into strings using mapping.

type StringKeys<T> = {
  [key in keyof T]: string;
}

Answer №2

type StringTypeExample{
 [index:string]:string;
}

Answer №3

If you want to work with keys and values that can be any string, the Record utility type is perfect for you.

type CustomType = Record<string, string>;
