Learn the proper way to specify the return type of a function as a class, rather than an instance, in Typescript

Is there a way to declare that a function returns a generic class definition? I have tried the following for non-generic classes, but it does not work for generic ones:

export function composeAll(composeFunction: Function, depsFunction: Function):
(component: any) => typeof React.Component; // works

export function composeAll<V>(composeFunction: Function, depsFunction: Function):
(component: any) => typeof React.Component<V, {}>; // fails

Any solutions or insights would be greatly appreciated. Thank you!

Answer №1

Forget about using the typeof. Just keep it simple with:

export function composeAll(composeFunction: Function, depsFunction: Function): 
    (component: any) => React.Component;

Also consider:

export function composeAll<V>(composeFunction: Function, depsFunction: Function): 
    (component: any) => React.Component<V, {}>;

Instead of a type query, what you're attempting is more suited for a different approach.
