I’m trying to make readable code for my API calling module and I want to have this convention:

@API
export class Users {
    async getUser(id: number) {
        // some stuff...
    }
}

import { Users } from 'users.ts';

const data = await Users.getUser(1);

I tried to write an API decorator to return and export instances of the API call group class. The code works when I use type any for the class but I don’t want to use type any. there is a problem with types.

The API decorator:

function API<T>(constructor: new (...args: any[]) => T) {
    return new constructor();
}

@API // Error: TS1270: Decorator function return type Namespace is not assignable to type void | typeof Namespac
export class Namespace {
    getNamespaces() {
        console.log('hello namespace');
    }
}

Namespace.getNamespaces(); // Error: TS2339: Property getNamespaces does not exist on type typeof Namespace

What should I do to fix this?
