🚀 Today I Learned How to Send Emails Using Node.js & Nodemailer (OAuth2 + Gmail)
As part of improving my backend development skills, I implemented an email sending system using Node.js and Nodemailer with secure Gmail OAuth2 authentication.
Instead of using basic passwords, I configured OAuth2 for better security and production-ready implementation. 🔐
🔹 Loaded environment variables using dotenv
🔹 Configured Gmail transporter with OAuth2 (Client ID, Client Secret, Refresh Token)
🔹 Verified SMTP connection before sending emails
🔹 Built a reusable sendEmail() function
🔹 Supported both plain text and HTML email formats
This implementation can be integrated into:
✅ Authentication systems (Email verification)
✅ Password reset features
✅ Notification systems
✅ Contact forms
Learning how backend services communicate with email servers gave me deeper understanding of real-world application architecture.
Excited to keep building and improving my full stack development journey 💻🔥
