What is the best possible approach to connect seriate node.js with a web application

Question

I am actually involved in a POC and looking to build a web app which can display SQL results after hitting a button. Got to know that seriate node.js is a good platform for this. But unable to find out how to link these components. Any help towards this would be appreciable.

You can check the below code

var webconfig = {
    user: 'login',
    password: 'sa@123',
    server: 'localhost', 
    database: 'TestDB',

    options: {
        encrypt: false // Use this if you're on Windows Azure 
    }
}

var express = require('express');
var sql = require('mssql');
var http = require('http');

var app = express();
var port = process.env.PORT || 8000;

var connection = new sql.Connection(webconfig, function(err) {
    var request = new sql.Request(connection); 
    request.query('select * from Users', function(err, recordset) {
       if(err)      // ... error checks 
            console.log('Database connection error');

    console.dir("User Data: "+recordset);
    });
});


app.listen(port);
console.log(port+' is the magic port');
