Different ways of retrieving indexed objects from a tuple list of properties in Typescript

Given the following input:

type Props = ['a', 'b', 'c']

The output derived from the Props type is as follows:

type Obj = {
 a: string,
 b: string,
 c: string
}

Although it seems tricky, I am confident that a solution is achievable.

Answer №1

To retrieve a combination of the string literals in Props (Props[number]), you can utilize a type query. Afterwards, you can create the specified props as strings using Record.

type Object = Record<Props[number], string>
