Getting error while trying to connect with postgres databse from react ES6

I am trying to set up a database connection from my existing react app. But I am getting net.Socket is not a constructor error. I have seen this Node JS: net.Socket is not a constructor but still can't figure out what should I do. I have tried using websocket but then I am getting some other exception -websocket is not a constructor.

Here is my code

import { Client } from 'pg';

const app = express();
const query = 'SELECT id, description, name, salary FROM public.usecase_details';
const client = new Client({
  user: 'out',
  host: 'pgn.example.com',
  database: 'salary_details',
  password: 'out',
  port: 1032,
});
client.connect();

client.query(query)
.then((res) => {
  console.log('Table is found');
})
.catch((err) => {
  console.error(err);
})
.finally(() => {
  client.end();
});

Can I please get some idea/ help to solve this issue?

here are the error details:
