[英]How to extend a TypeScript interface and unpartial it
I want to be able to do the following: 我希望能够执行以下操作:
interface Partials {
readonly start?: number;
readonly end?: number;
}
interface NotPartials extends Partials /*incorporate Unpartialing somehow */ {
readonly somewhere: number;
}
Then, NotPartials would be: 然后,NotPartials将是:
readonly start: number;
readonly end: number;
readonly somewhere: number;
Notice how start and end are required now. 注意现在如何开始和结束。 Is this possible anyway? 反正有可能吗?
Well, this is silly. 好吧,这很愚蠢。
I think in TypeScript 2.8 this is possible: 我认为在TypeScript 2.8中这是可能的:
interface Partials {
readonly start?: number;
readonly end?: number;
}
interface NotPartials extends Required<Partials> {
readonly somewhere: number;
}
