How to render React on the server?

Question

JavaScript

The task is to get html on the server side from React components.
Stumbled with babel.
In general, in all examples, all templates are written without quotes. I am also getting an error. I understand that babel is needed.
Connected.

var code = 'export default React.createClass({
  getInitialState() {
    return { num: this.getRandomNumber() };
  },

  getRandomNumber(): number {
    return Math.ceil(Math.random() * 6);
  },

  render(): any {
    return <div>
      Your dice roll:
      {this.state.num}
    </div>;
  }
});';

var qwerty = babel.transform(code, {
  presets: [
    "es2015",
    "react",
    "stage-0"
  ]
});
console.info(qwerty);

I'm getting a burst of data. I need pure html to be output.
Well, I need to display it in the browser. The task is to save html to a file.
