Using object destructuring to require() Express Router

Question

This code works:

const express = require('express');
const Router = express.Router();

Router.get('/hello-world', (req, res, next) => {                                     
    res.send("hello world!"); //works great                   
});

But this code doesn't:

const {Router} = require('express');

Router.get('/hello-world', (req, res, next) => {                                     
    res.send("hello world!"); // :( doesnt work                  
});

What am I misunderstanding about destructuring? Thanks

You would still need to call the function:

const {Router} = require('express');
Router().get('/hello-world', (req, res, next) => {
//    ^^
    res.send("hello world!"); // :( doesnt work                  
});

What am I misunderstanding about destructuring?

The code

const {Router} = require('express');

is equivalent to

const temp = require('express');
const Router = temp.Router;

but you were doing

const express = require('express');
const Router = express.Router();
//                           ^^
