var express = require('express');
// Initializing the express and port number
var app = express();
// Initializing the router from express
var router = express.Router();
var PORT = 3000;
// Defining an endpoint
app.get('/api', function(req, res){
// Setting the Content-type
res.set({
'Content-Type': 'application/json',
});
// "text/plain"
console.log(res.get('Content-Type'));
res.end();
});
app.listen(PORT, function(err){
