How to set Cookie in Electron React using npm react-cookie package?

i am trying to set cookie in electron-react app using npm react-cookie package

and setting cookie like that

import { useCookies } from "react-cookie";
const [cookies, setCookie, removeCookie] = useCookies();
setCookie("isWorking", 121, { path: "/" });

its work fine in development mode but as i build electron application its not set my cookies in build application

SnapShot of cookies in development

Snapshot in Production/electron build application

In production, mode electron runs your react application in the file system so cookies never be saved in the file system in order to save cookies you have to run electron-react application in serve mode

  const server = require("./server");

    const createServer = async () => {
      if (isDev) {
        createWindow();
        win.loadURL("http://localhost:3000");
      } else {
        let port = null;
        for (let i = 5001; i < 6000; i++) {
          let isFree = await isPortFree(i);
      
          if (isFree) {
            port = i;
            break;
          }
        }
        currentPort = port;
        server.listen(port, () => {
          console.log(`Example app listening at http://localhost:${port}`);
          createWindow();
          win.loadURL(`http://localhost:${currentPort}`);
        });
      }
    };
app.whenReady().then(createServer);

and you server.js file will be like that

const path = require("path");
const express = require("express");

const app = express();

app.use(express.static(path.join(__dirname, "/app")));

app.get("/", (req, res) => {
  res.sendFile(path.join(__dirname, "/app/index.html"));
});

module.exports = app;
