Different Versions of Type in Typescript: Generic vs Non-Generic

Having a quick question here! How can I create two classes with generic type arguments in typescript?

export class ServiceResponse { }

export class ServiceResponse<T> extends ServiceResponse {}

I encountered an issue where TypeScript flagged these as duplicate identifiers. Can you declare the same name with a generic type argument in TypeScript? Has anyone dealt with this challenge before? In C#, this scenario is frequently seen.

Appreciate your help!

Answer №1

Responding to the previous comment, Aleksey wanted to elaborate on the answer and provide more information for future use

The reason behind the issue is due to the fact that when Typescript code is compiled to JavaScript, the type annotations are removed, resulting in classes with the same name causing a duplicate identifier error.

To address this, you can define both a generic and non-generic version of the class by setting a default value for the generic type parameter:

export class ServiceResponse<T = void> {
}
