MongoDB not saving data because "Uncaught ReferenceError: require is not defined"

Question

I'm testing NodeJS and MongoDB. So, I've created an html file with a form.

That form grabs the user input and tries to save it to a Mongo database.

I've tried manually inserting the values into mongo using the console and it works.

I've started node server writing down node at the terminal, inside my EC2 amazon web server. I've already installed both (node and mongo).

The form looks like this:

<form>
<input type="email" name="email" class="form-control" id="email">
<input type="submit" onclick="avisoPago.insertarDB()" class="btn btn-danger" value="Avisar del pago ahora"></input>

And here's what I'm trying to do in the js file:

"use strict";
const mongojs = require("mongojs");
//string connection
const db = mongojs("localhost:27017/pagosDB",["pagosDB"]);

var avisoPago = {
    email: function () {    return $('#email').val();   },    
    insertarDB: function(){
            db.pagos.insert({
                email:"[email protected]",
                //I've also tried email:"this.email()",
                estado: "pendiente"
            });
    }

}

I've also installed mongojs (using npm install mongojs).

But I get this error avisos-de-pago.js:4 Uncaught ReferenceError: require is not defined

Note: Line 4 of the JS file is: const mongojs = require("mongojs");)

I know thata there is something very silly that I'm missing here...

NodeJS is a server-side technology, not a client-side technology. In this case, NodeJS calls, like require(), do not work in the browser.

See browserify or webpack if you wish to serve browser-specific modules from NodeJS.
