Send email with Gmail - Nodemailer

How to send an email with your personal gmail account using Nodemailer

Prerequisite:

Nodejs (Installed)

Before running any of the following steps. Make sure you run npm install to install any dependencies needed for this project.

Step 1

Create a file named .env, and copy everything inside the .env-example file to the .env file. Inside the .env file, fill in the information with your email and password.

Step 2

We need to define our nodemailer transporter to connect to our service. Make sure you fill in with your credentials such as email and password.

let transporter = nodemailer.createTransport({
    service: 'gmail',
    auth: {
        user: process.env.EMAIL || 'abc@gmail.com', 
        pass: process.env.PASSWORD || '1234'
    }
});

Step 3

Define a mailOptions variable. It should contains information that your receiver should know about it.

let mailOptions = {
    from: 'abc@gmail.com', 
    to: 'cba@gmail.com',
    subject: 'Nodemailer - Test',
    text: 'Wooohooo it works!!'
};

Step 4

In order to send an email with nodemailer, we need to bring the transporter that we previously configured above, and invoke the sendMail function. If everything goes well, you should receive an email.

transporter.sendMail(mailOptions, (err, data) => {
    if (err) {
        return log('Error occurs');
    }
    return log('Email sent!!!');
});

Once you have successfully completed the above steps. Run npm start to send an email
