Include a fresh attribute in the Interface

How can I include a boolean property

isPhotoSelected: boolean = false;
in an API interface that I cannot modify? The current interface looks like this:

export interface LibraryItem {
    id: string;
    photoURL: string;
    thumbnailURL: string;
    fileName: string;
}

Answer №1

Create a class that will implement the specified interface.


export class CustomLibraryItem implements LibraryItem {
    // Ensure to define all required properties of the interface here
    isSelected: boolean
}

Answer №2

Have you considered exploring declaration merging? It appears to align more closely with what you're seeking compared to your current accepted solution:

// importing from a module
import { LibraryItem } from 'librarymodule'; 

// locally extending the module's interface declaration  
declare module './playground' {
  export interface LibraryItem {
    isPhotoSelected: boolean
  }
}

// utilizing it
const libtaryItem: LibraryItem = {
  id: 'id',
  photoURL: 'https://example.com/photo.jpg',
  fileName: 'fileName.ext',
  thumbnailURL: 'https://example.com/thumbnail.jpg',
  isPhotoSelected: true
}

I hope this information proves helpful; best of luck!
