How to embed an html page in react created with create-react-app?

Question

React

I'm trying to insert a page using a new component:

var html = require('./index.html');
const RegForm = () => {
    return (
        <div>
            <iframe src={html}></iframe>
        </div>
    )
}

export default RegForm;

Here is the error that it throws:
./src/Components/RegForm/index.html 1:0
Module parse failed: Unexpected token (1:0)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
Is there another way to import html?
