Typescript: Eliminate the intersection type from the primary type

I am new to Typescript and currently facing a roadblock with this specific issue. I have defined a type as:

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

My objective is to create a type that does not include the Node type.

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


// I attempted to use Exclude, but it just returns never
type SecondaryType = Exclude<MainType, Node>

//I also experimented with Omit, however, it doesn't allow me to exclude Node
type SecondaryType = Omit<MainType, Node>

Answer №1

In order to exclude all the keys of the Node type, you can use the following code:

type SecondaryType = Omit<MainType, keyof Node>
