Extending express.Router

Question

Is there a way to extend express.Router ?

I tried this :

class Test extends express.Router() {

};

But express throws me an error.

Any solution ?

The right way to do it:

class Test extends express.Router {
    constructor() {
        super();
        this.get('/', (req, res) => console.log('test'));
    }
};

When you write express.Router() (with parentheses) you already call the constructor and therefore you're trying to extend an object instead of class.
