res.set('Content-Type', 'text/html');

var express = require("express");
var app = express();

app.set("view engine", "ejs");
app.get("/", function (req, res) {
 res.render("haha", {news:[]});
});

app.listen(3000);

app.get("/check", function (req, res) { 
 res.set('Content-Type', 'text/html'); 
 res.send({ 
 "user" : "ok"
