Setting up huge mail server for just sending the informing mail on completion of code ?

That's not anyone likes ! ( I Guess.... )

So, today i am sharing snippet for sending mail using gmail account and a node mailer API.

Before stating

setup your mail account :-

Enable the less secure app access of your google account in order to send mail from any custom agent like Node.js.

This is mandatory else where node-mailer will throw authentication-failed exception

Step 1 : install node-mailer and perform basic configuration

I assume you have installed the nodemailer successfully using npm or yarn. I used npm here. If not then paste this into your terminal

npm i node-mailer --save

After this, i will import node-mailer using CommonJS syntax and create the basic configuration object in order to create mail - transporter object. The object will handle the SMTP (Simple Mail Transfer Protocol) and will perform necessary steps to put mail into recipient's inbox

( fav person In my case)

const nodemailer = require("nodemailer");

module.exports = {
    sendMail: function () {
        let mailTransporter = nodemailer.createTransport({
            service: "gmail",
            auth: {
                user:"yourUserName@gmail.com",
                pass: "<SecretPassword",
            },
        });
    },
}

Step 2: create mailer payload : Mailer payload will be consisting of recipient mail, subject of email and related stuff. We can manipulate it just as we want but, i will keep it simple

let mailDetails = {
            from: "yourUserName@gmail.com",
            to: "favPerson@anyDomain.com",
            subject: "You Were Hacked 8)",
            text: "System failure !",
        };

Step 3 : Fire

Execute the sendMail() function with proper args to execute the code . It will send the email and give you result in terminal.

 mailTransporter.sendMail(mailDetails, function (err, data) {
            if (err) {
                console.log("Error Occurs");
            } else {
                console.log("Email sent successfully");
            }
        });

This is it. we successfully sent the mail using gmail and node. This is pretty helpful when informing some once else on the certain recurring events.
