In TypeScript, the nested object structure ensures that each property is unique and does not repeat within

Here is the current state of my interface. I am wondering if there is a way to streamline it to avoid repeating properties in both parts.

export interface Navigation {
    name: string;
    roles: Array<number>;
    sublinks: NavigationItem[];
}

export interface NavigationItem  {
    name: string;
    roles: Array<number>;
    url: string;
}

Answer №1

declare interface NavBase {
    title: string;
    permissions: number[];
}

declare interface NavigationMenu extends NavBase {
    subItems: NavItem[];
}

declare interface NavItem extends NavBase {
    link: string;
}
