How to properly send data to neo4j from .js file?

I am trying to send data in neo4j database from .js file like so:

import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
var neo4j = require("neo4j-driver");
var driver = neo4j.driver(
  "neo4j://localhost",
  neo4j.auth.basic("neo4j", "something")
);

console.log(driver);

var session = driver.session({
  database: "neo4j",
  defaultAccessMode: neo4j.session.WRITE,
});

session
  .run("CREATE (n:User{nickname: 'Mama africa', reputation: '1789', authtoken: 'bad18eba1ff45jk7858b8ae88a77fa30', registered: 7/26/2022, postamount: 49 })")
  .subscribe({
    onKeys: (keys) => {
      console.log(keys);
    },
    onNext: (record) => {
        console.log(record.get("n"));
      },
      onCompleted: () => {
          session.close(); // returns a Promise
        },
        onError: (error) => {
            console.log(error);
          },
        });
      
const root = ReactDOM.createRoot(document.getElementById("root"));
      
      
      root.render(
        <React.StrictMode>
      <App />
  </React.StrictMode>
);

This is my React project and this .js file is in 'front' folder. So should I create separate folder for example 'back' send data from 'front' to 'back' and therefore send data from 'back' to Database or it doesn't matter?
