In the particular case, I would like to create a form for contact, with name, type of service (dropdown menu: webdesign, mobile), subject and message. I would also like to send this form with name, type of service and message to a specific email in text format.
Usually the validation of a form is done on the server with ASP, Java. Now, would it be possible to validate with JavaScript only? What technology is required to do this?
You can use Client-Side validation with Javascript (pure or using some library like JQuery, AngularJS, etc.). This will occur before you send the data to the server. Something like this:
function Valida() {
if (document.getElementById("nome").value.length < 1) {
alert("Digite um nome.");
document.getElementById("nome").focus();
return false;
} else if (document.getElementById("idade").value.length < 1) {
alert("Digite uma idade.");
document.getElementById("idade").focus();
return false;
} else if (document.getElementById("sexo").value == 0) {
alert("Escolha um sexo.");
document.getElementById("sexo").focus();
return false;
} else {
return true;
}
}

You can (and recommend) do the validation also on the server side using NodeJS and Javascript.
The code is great, check out link .
You can send txt or html emails using nodemailer, plugin for express:
var nodemailer = require('nodemailer');
// create reusable transporter object using the default SMTP transport
var transporter = nodemailer.createTransport('smtps://user%40gmail.com:[email protected]');
// setup e-mail data with unicode symbols
var mailOptions = {
