How to connect mongoDB in react

Such a problem that when I try to simply connect mongoDB in react

import React, {Component} from 'react';

export default class App extends Component{

  componentDidMount(){
    const {MongoClient} = require('mongodb');

    const client = new MongoClient('mongodb+srv://dafu4k:****@cluster0.jd26aac.mongodb.net/?retryWrites=true&w=majority');

    const start = async () => {
    try{
        await client.connect();
        console.log('Connected')
    }
    catch(e){
      console.log(e)  
    }
  }
  start();
 }

  render(){
    
  return (

    <>
    <h1>Home page</h1>
    </>
  )

  }
}

Errors of the same type appear in the browser itself

Module not found: Error: Can’t resolve ‘os’ in ‘C:UsersDaFu4OneDriveРабочий >столmongotestmongo-testnode_modulesiplib’

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:

• add a fallback ‘resolve.fallback: { "os": require.resolve("os-browserify/browser") }’
• install ‘os-browserify’
  If you don’t want to include a polyfill, you can use an empty module like this:
  resolve.fallback: { "os": false }

They differ in that the last line has different keys (timers,crypto,http, etc.)

I watched how to connect mongoDB to react, everywhere they used a certain mongoose along with mongoDB, but I can’t understand, maybe it’s required to connect to react, or am I still doing something wrong? (in normal js everything works fine, the code has not changed)

src/index.js

import React from 'react';
import ReactDOM from 'react-dom/client';

import App from './App';
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>
);
