Using TypeScript's `extend` keyword triggers an ESLint error when attempting to extend a generic type

I am dealing with numerous models that include additional meta data, which led me to create a generic type for appending them to the models when necessary:

type WithMeta<T> = T extends Meta;

However, I encountered an error stating: Parsing error: '?' expected.

Unfortunately, ESLint did not specify which rule triggered this error. Any insights from anyone here would be greatly appreciated. Thank you!

Answer №1

After some troubleshooting, I managed to solve my problem involving the use of &:

interface Information {
  dateCreated: string;
  lastUpdated: string;
}

type IncorporatingMeta<S> = S & Information;
