Question: Net.createConnection is not a function

Is more a question than an error, I already know in a browser environment the net module is supposed to not exists, but I’m writing a electron app with angular2 and i’ve tested this script:

<script>
var connection = mysql.createConnection({
      host     : 'localhost',
      user     : 'user',
      password : 'password',
      database : 'test'
});

console.log( connection.connect() )
</script>

and is working good, since electron is node based and can interact with filesystem and net.

But the problem come when I try to put in a angular2 component this:

import { Component } from '@angular/core';
import * as mysql from 'mysql';

export class AppComponent {

  constructor() {

    var connection = mysql.createConnection({
      host     : 'localhost',
      user     : 'user',
      password : 'password',
      database : 'test'
    });

    console.log( connection.connect() )
  
 }

}

it says: Net.createConnection is not a function…so my question is… why? what’s happening?

Any hint is appreciated. Many thanks in advance.
