Is there a way to define a custom type named TestType that extends the existing BaseType, while also accepting a generic type as input?
Consider the following code snippet:
type BaseType={
id:number
}
interface TestType<T=any> extends BaseType {
prop1:string;
[key: string]: T;
}
When implementing this code, I encounter an error labeled TS2411:
Property 'prop1' of type 'string' is not assignable to 'string' index type 'T'.
Any suggestions on how to resolve this issue?
Ensuring that the index signature [key: string]: T does not create conflicts with explicitly declared properties is crucial.
type BaseType = {
id: number;
};
interface TestType<T = any> extends BaseType {
prop1: string;
[key: string]: T | string | number; // Ensures compatibility with prop1 and id
}
