interface Configuration {
[input: string]: any;
}
This is really puzzling to me, the 'input' is declared as a string type with any value?
Appreciate your help.

When objects implement the Options interface, they become indexable. This means that a key of type string can be used to access any value.
According to https://www.typescriptlang.org/docs/handbook/interfaces.html:
Indexable Types
We can define types that we can access like a[10], or ageMap["daniel"]. Indexable types have an index signature indicating the types we can use for accessing the object and their corresponding return types.
For example:
interface StringArray {
[index: number]: string;
}
let myArray: StringArray;
myArray = ["Bob", "Fred"];
let myStr: string = myArray[0];
