Answer 1

create a config folder and create a file databaseConfig.js
var mysql = require('mysql');
config = {
host: 'localhost',
user: 'root',
password: '',
database: '<DB name>'
}
var connection =mysql.createConnection(config); //added the line
connection.connect(function(err){
if (err){
console.log('error connecting:' + err.stack);
}
console.log('connected successfully to DB.');
});
module.exports ={
connection : mysql.createConnection(config)
}
create a app.js file
var express = require('express');
var cors = require('cors');
app = express(),
app.use(cors()),
port = process.env.PORT || 3001;
bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
var routes = require('./api/routes/routes'); //importing route
routes(app);
console.log('todo list RESTful API server started on: ' + port);
app.listen(port);
create a controller.js file
var config = require('../../databaseConfig.js');
var connection= config.connection
connection.query ('CREATE DATABASE mydb', function(error, results){
if (results){
console.log(results);
}
else{
console.log(error);
}
});
