Deep dive: Use JavaScript to send emails

In principle, sending emails from a web application could seem easy, but in reality, it calls for a deep comprehension of email servers and email sending protocols. For security and functional reasons, JavaScript, which is typically used for client-side development, cannot send emails directly. It is still possible to send emails from JavaScript programs, though. This can be resolved by using third-party backend servers or APIs to handle email sending functionality.

In actuality, server-side JavaScript email sending is much simplified by tools such as Nodemailer for Node.js. With the aid of these tools, developers can effortlessly set up mail servers, send HTML emails with plenty of content, control attachments, and even set up more complex settings like authentication and encryption. Moreover, employing email sending providers like SendGrid or Mailgun can provide extra features like analytics reporting, email tracking, and improved spam management, offering a comprehensive answer for any online application's email sending requirements.

const nodemailer = require('nodemailer');
let transporter = nodemailer.createTransport({
  service: 'gmail',
  auth: {
    user: 'votre.email@gmail.com',
    pass: 'votreMotDePasse'
  }
});
let mailOptions = {
  from: 'votre.email@gmail.com',
  to: 'destinataire.email@example.com',
  subject: 'Envoi d\'email via Node.js',
  text: 'Bonjour, ceci est un email envoyé via Node.js et Nodemailer.'
};
transporter.sendMail(mailOptions, function(error, info){
  if (error) {
    console.log(error);
  } else {
    console.log('Email envoyé: ' + info.response);
  }
});
