Can You Specify Multiple Type Constraints For TypeScript Generics

Question

I have a generic interface like this example with a single type constraint:

export interface IExample {
    getById(id: number): T;
         


        

Answer 1

Typescript doesn't offer a syntax to get multiple inheritance for generic types. However, you can achieve similar semantics by using the Union types and Intersection types. In your case, you want an intersection :

interface Example {}

For a Union of both types :

interface Example {}
