打字稿嵌套对象，因此属性不会重复

Question

我的界面目前看起来像这样。是否有可能重构它，以便在两者中不再重复属性。

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

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

Answer 1

export interface NavigationBase {
    name: string;
    roles: number[];
}

export interface Navigation extends NavigationBase {
    sublinks: NavigationItem[];
}

export interface NavigationItem extends NavigationBase {
    url: string;
}
