Declaring variables from object property

I have a simple object with constants.

{
  KEY1: "value1",
  KEY2: "value2"
}

I want to make them accessible globally.
I make this object globally, use it like Config.KEY1
But I am trying to find a way so that I only use KEY to get the value.
app.js

const express = require('express')
const app = express()

//load app config variables
const config = require('config') //this returns the plain object with config keys and dvalues
...config //oops, can't do this :(

If I could do somthing like below, I think it should work.

const express = require('express')
const app = express()

//load app config variables
const KEY1 = "value1"
const KEY2 = "value2"

Destructure the config object when you import it, so that you have standalone variable names:

const { KEY1, KEY2 } = require('config');

You can also combine the config with the global object, allowing you to use those standalone variable names anywhere without importing the config everywhere, but it's not such a good idea IMO:

const util = require('./util');
Object.assign(global, util);

(make sure you don't have any properties that conflict with properties on the global object)
