// Happy coding guys
const express = require('express');
const app = express()
const port = 3000

const router = require('./router/index.js');

app.set('view engine','ejs');
app.use(express.urlencoded({extended:true})); // ini middleware
app.use('/',router);



app.listen(port, () => {
  console.log(`Example app listening on port ${port}`)
})
