Typescript：从主类型中删除交叉类型

Question

我是 Typescript 的新手，并陷入了这个问题。所以，我有一个类型定义为：

type MainType = Node & {
  id: string;
  name: string;
  notifications: number
}

我想要一个不包含Node类型的类型。

//Expected type
 {
  id: string;
  name: string;
  notifications: number
 }


// I tried using Exclude, but it returns never
type SecondaryType = Exclude<MainType, Node>

//I tried using Omit, but that doesn't allow me to pass Node
type SecondaryType = Omit<MainType, Node>

Answer 1

您需要省略类型中的所有键Node：

type SecondaryType = Omit<MainType, keyof Node>
