What would be the right way to present business objects in the front end?
There is a backend that returns list of persons.
It gets automatically mapped into collection of TypeScript busness object class (Person) objects using Angular/rxjs.
export class Person {
Id: string;
Name: string;
Age: number;
}
There is a need to display these entities in a list with an additional column, stating whether records are selected or not - required for further processing.
The question is - what would be the right way to do this?
Should I create a PersonModel class that inherits from Person and add additional field in there?
export class PersonModel extends Person {
Selected: boolean;
}
Or, should I ignore the fact that back-end has nothing to do with the Selected property and simply add the property to the Person class?
export class Person {
Id: string;
Name: string;
Age: number;
Selected: boolean;
}
Are there other, more proper ways of dealing with such situation?

Instead of Class, You can create an interface which extends another interface.
export interface Person {
Id: string;
Name: string;
Age: number;
}
export interface PersonAttrib extends Person {
Selected: boolean;
}
