You will always need a backend that will send you email, this is indispensable (but using NodeJS, you do the sending, which is only JS).
An example of this using JS
+ NodejS
<input type="email" id="email">
<textarea id="msg"></textarea>
<button id="btn">Entrar em Contato</button>
<script>
document.getElementById('btn').onclick = function(){
let email = document.getElementById('email').value
let msg = document.getElementById('msg').value
// Exemplo usando axios
axios.post('SUA URL', {
email: email,
msg: msg
})
.then(response => {
alert('FOI')
})
.catch(error => {
alert('ERRO')
})
}
</script>
// Do lado do servidor com Node
'use strict';
const nodemailer = require('nodemailer');
// Generate test SMTP service account from ethereal.email
// Only needed if you don't have a real mail account for testing
nodemailer.createTestAccount((err, account) => {
// create reusable transporter object using the default SMTP transport
let transporter = nodemailer.createTransport({
host: 'smtp.ethereal.email',
port: 587,
secure: false, // true for 465, false for other ports
auth: {
user: account.user, // generated ethereal user
pass: account.pass // generated ethereal password
}
});
// setup email data with unicode symbols
let mailOptions = {
