suppose in the folder /src/public, there is some html pages.
const express = require('express')
const router = express()
router.listen('5002', () => {
console.log('listening on 5002');
});
router.use(express.static('./src/public'))
b. one quick way to extract value from a post form is using body parser
const express = require('express');
const bodyParser = require('body-parser');
const app = express()
app.listen('5000', () => {
console.log('listening on 5000');
});
app.use(bodyParser.json());
api.post('/test', (req, res) => {let lastName= req.body["Last Name"] let firstName=req.body["First Name"]
});
