how to access dom in npm module

Question

I am writing a NPM package and I want to write something to the DOM inside my function. But I get an error saying the document is not defined example,

foo package:

module.exports = {
    sayHello: function(){
        document.getElementByID('#hello').innerHTML('Hello');
    }
}

In client-side javascript:

import { sayHello } from 'foo';
$('#myButton').click(() => sayHello());

Answer 1

First of all there is a typo at

document.getElementByID

The correct spelling is

document.getElementById

Besides that the question may be a duplicate of this question
