npm install react-simple-captcha

import { loadCaptchaEnginge, LoadCanvasTemplate, LoadCanvasTemplateNoReload, validateCaptcha } from 'react-simple-captcha';

render() {
     return (<div>
         <LoadCanvasTemplateNoReload />
         </div>);
 };
Validate captcha by using validateCaptcha(user_captcha_value)

doSubmit = () => {
<! --   let's assume there is an HTML input text box with id 'user_captcha_input' to get user input -->   
     let user_captcha_value = document.getElementById('user_captcha_input').value;

     if (validateCaptcha(user_captcha_value)==true) {
         alert('Captcha Matched');
     }

     else {
         alert('Captcha Does Not Match');
     }
 };
