Typescript question: interface that extends a generic

[Christophe HOARAU]

Hello,

I know this is not specific to angular, but as angular is one of the most active typescript users I was wondering if someone could help me on this one.

I want to create an interface that extends a generic. Something like this :

export interface A{
    A: string;
}

export interface AB{
    B: string;
}

export interface AC{
    C: string;
}

export interface AX<T extends A> extends T{
    X: string;
}

This way I could use AX in places where I need A and X.
I know this might sound a bit weird, but I really need this.

Thanks.

Best regards.

Typescript has composition, so this really isn't necessary.

interface A {}

interface X {}

function f(ax: A&X) {}

Thanks I'll try that, I don't know why I didn't thought about it. I already used this syntax.
