Integrating Nodemailer in a Node.js Project
To integrate Nodemailer in a Node.js project, you can follow these steps:
1. Install Nodemailer
npm install nodemailer --save
This will install Nodemailer and add it to your project's dependencies .
2. Set Up Nodemailer in Your Project:
After installing Nodemailer, you can include it in your Node.js application using the following code:
var nodemailer = require('nodemailer');
If you are using ES modules, you can use the import statement instead .
3. Create a Transporter:
Use the createTransport method to create a transporter for sending emails. You can specify the email service (e.g. Gmail, outlook, aws ses ect.) and provide authentication details:
var transporter = nodemailer.createTransport({
service: 'gmail',
auth: {
user: 'youremail@gmail.com',
pass: 'yourpassword'
}
});
-------------------------or--------------------------
var transporter = nodemailer.createTransport({
service: "Outlook365",
host: "smtp.office365.com",
port: "587",
auth: {
user: 'youremail@gmail.com',
pass: 'yourpassword',
},
requireTLS: true,
});
Replace 'youremail@gmail.com' with your email address and 'yourpassword' with your email password .
4. Send an Email:
Once the transporter is set up, you can use it to send an email. Here's an example of how to send a simple email:
var mailOptions = {
from: 'youremail@gmail.com',
to: 'recipient@example.com',
subject: 'Subject of the Email',
text: 'Body/template of the Email'
};
transporter.sendMail(mailOptions, function(error, info) {
if (error) {
console.log(error);
} else {
console.log('Email sent: ' + info.response);
}
});
Replace 'youremail@gmail.com' with your email address, 'recipient@example.com' with the recipient's email address, and provide the subject and body of the email as needed .
These steps outline the process of integrating Nodemailer in a Node.js project and sending emails using Nodemailer and Gmail/outlook/aws ect. Remember to handle sensitive information such as email credentials securely in your project.
Conclusion
If you want to make you gmail/outlook will able to send email through code, you will also need to provide authentication of nodemailer in setting of gmail/aws/outlook etc.
For best practice, put all the credential in .env file, and call it in the function to make active.
e.g:
.env file
SMTP_PASS = xxxxxxxx
SMTP_HOST = amazonaws.com / gmail / office365.com
STMP_PORT = 5187
FROM_Email = youremail@gmail.com
create an export function to call when send an mail.
export function mailSend(email_id, otp) {
let mailTransporter = nodemailer.createTransport({
service: 'aws',
host: process.env.SMTP_HOST,
auth: {
user: process.env.SMTP_USER_NAME,
pass: process.env.SMTP_PASS
}
});
let mailDetails = {
from: process.env.FROM_Email,
to: `${email_id}`,
subject: 'Otp send by Team',
text : `OTP is ${otp}`
};
mailTransporter.sendMail(mailDetails, function(err, data) {
if(err) {
console.log('Error Occurs', err);
} else {
console.log('Email sent successfully');
}
});
}
Call mailSend function when you want to initiate nodemailer to send otp.
mailSend(email_id, '983844');
