Just an example of not using body-parser

server.js

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

const app = express();
const PORT = 3000;

app.use(express.json()); // JSON-encoded body
app.use(express.urlencoded({extended: true}));  // URL-encoded body
app.set('view engine','ejs');


let pool = mysql.createPool({
  connectionLimit: 100,
  host: '',
  user: '',
  password: '',
  database: '',
  port: 1111,
});

app.get(`/database`, (req, res) => {
  // Database connection
  pool.getConnection((error, connection) => {
    if (error) {
      connection.release();
      throw error;
    }
    connection.query(``, (error, row, fields) => {
      // Query
    });
    connection.release(); // End
  })
});

// Post
app.post(`/`, (req, res) => {
  console.log(req.body);
  /*
    If we sent a form post request with
    key : value
    We can access doing
    req.body.key
    So if it was age it would be
    req.body.age
   */
});

// Get
app.get(`/`, (req, res) => {
    res.send('Running :3000')
});

app.listen(PORT, () => { console.log(`Listening -> ${PORT}`);});
