How to serve multiple HTML files with React?

I want to build a web application with React with multiple HTML pages. For example login.html and index.html. I've created these HTML pages and mapped them to URIs with my backend. So I have localhost:8080/login and localhost:8080/index. Unfortunately, React only uses the index.html file to render content!

So index.html works and the React content is shown: localhost:3000/index.html

<!-- index.html -->
...
<body>
  <noscript>
      You need to enable JavaScript to run this app.
  </noscript>
  <div id="wizard"></div>
</body>
...

<!-- index.tsx -->
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import FetchData from "./FetchData";
import 'bootstrap/dist/css/bootstrap.min.css';
import './index.css';
import registerServiceWorker from './registerServiceWorker';

ReactDOM.render(
<div className="d-flex flex-column">
            <div className="bg-dark text-light AppHeading">Self-Service-Webwizard</div>
            <div className="bg-white"><FetchData /></div>
        </div>,
document.getElementById('wizard') as HTMLElement
);
registerServiceWorker();

But wizardLogin.html doesn't show the React content: localhost:3000/wizardLogin.html

<!-- wizardLogin.html -->
...
<body>
  <noscript>
      You need to enable JavaScript to run this app.
  </noscript>
  <div>Wizard login</div>
  <div id="wizardLogin"></div>
</body>
...

<!-- LoginPage.tsx -->
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import 'bootstrap/dist/css/bootstrap.min.css';
import './index.css';
import registerServiceWorker from './registerServiceWorker';
import LoginForm from "./LoginForm";

ReactDOM.render(
    <div>
        <div><h1>Wizard Login.tsx</h1></div>
        <div><LoginForm/></div>
    </div>,
    document.getElementById('wizardLogin') as HTMLElement
)
;
registerServiceWorker();

Am I doing something wrong or is it not possible to serve multiple HTML files with React?

Solution

So far I've learned that React native doesn't support multiple HTML pages because it's an single page application. I kept index.html as single HTML page and solved the issue with conditional rendering in react. When a condition is fullfilled then I'm rendering another React .tsx-file.
