Quickly set up modular routes for Express

const express = require('express');
const exphbs = require('express-handlebars');
const path = require('path');

// Database
const db = require('./config/database');

// test db connection
db.authenticate()
  .then(() => {
    console.log('Connection has been established successfully.');
  })
  .catch(err => {
    console.log('Unable to connect to the Database');
  });

const app = express();
const PORT = process.env.PORT || 5000;

// Routes
app.use('/gigs', require('./routes/gigs'));

// set up home route
app.get('/', (req, res) => res.send('INDEX'));

// Sets up the Express app to handle data parsing
app.use(express.urlencoded({ extended: true }));
app.use(express.json());

app.listen(PORT, console.log(`Server started on port ${PORT}`));

const express = require('express');
const router = express.Router();

router.get('/', (req, res) => res.send('GIGS'));

module.exports = router;
