2. Production URL is -> https://stg.abc.com/tools/forecaster.
   Local URL -> http://localhost:8081/tools/forecaster

routes.js

import React from 'react'
import {
  BrowserRouter as Router,
  Route
} from 'react-router-dom';
import login from './components/login';

const myTool = () => (
  <Router>
    <div>
      <Route exact path="/tools/forecaster" component={login}/>

      <Route exact path="/tools/forecaster_hs" component={login}/>

    </div>
  </Router>
)
export default myTool

server.js

const express = require("express");
const app = express();
const path = require('path');
const port = process.env.PORT || 8081 ;

app.use(express.static(path.join(__dirname, 'build')));

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

app.listen(port);

Expected behaviour

The static assets should load from the build path

Actual behaviour

The static assets are also loading index.html file . It is not loading these files.
