Answer 1

I suggest you to use some template engine, like ejs or jade . This form, you can use res.render and send json information for view. For more details consult the engine docs and res.render doc too.

Answer 2

If you need to render an html page on node.js express, you need to install any of the template engine like ejs or jade and set the view directory. The code used to install ejs using npm is,

npm install ejs --save

include the following code into your app.js file will resolve your problem.

var bodyParser = require('body-parser');
var express = require('express');
var app = express();

app.use(express.static(__dirname + '/'));
app.use(bodyParser.urlencoded({extend:true}));
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'ejs');
app.set('views', __dirname);

app.get('/', function(req, res){
    res.render("index");
});
