Convert a HTML file into PDF in ReactJS

Question

I need to download a HTML file in PDF format. I tried some plugins but that doesn't work. I need help.

import React from 'react';
class App extends React.Component {
    htmlToPdf()
    {
       //code need to be written
    }
    render() {

        return (
             <div>
              <button onClick={this.htmlToPdf}>download</button>
             </div>
           );

        }
     }


export default App;
