JavaScript Express Basics Deeper into Routing with Express The Response Object

My solution using pure nodeJS

Just did this for fun. Take a look. Took me a minute to realize the post is returning a URL and not just the query string. hence the require 'url' along with the require 'querystring'

const Express = require('express');
const app = Express();
const querystring = require('querystring');
//app.use(Express.urlencoded({ extended: true}))
app.set('view engine', 'pug');
const port = 3000;

app.get('/', (req, res) => {
  res.render('index', {prompt: "Guess a number", hint: "1-10"});
});

app.get('/hello', (req, res) => {
  res.render('hello');
});
//unsafe POST request in pure nodejs
app.post('/hello', (req, res) => {
  let body = '';
  let result
  req.on('data', (chunk) => {
      body += chunk.toString();
  }).on('end', () => {
    result = querystring.parse(body);
    res.render('hello', {username: result.username});
  })
});

app.listen(port, () => {
  console.log(`Listening at http://localhost:${port}`);
});

Nice job, It's always a fun learning experiment to try and recreate things done in libraries that pull away all that abstraction from you. Great way to understand what's going on underneath the hood and as such a better way to gain more knowledge in the field subset.

Thank you, I could not agree more. I always enjoy a good rabbit hole. XD
