Today I continued improving DevConnect (the project I'm building as I learn Next.js) by adding two important security features.
I integrated email verification and password reset using Better Auth with Resend, which gave me a better understanding of how authentication libraries handle secure email flows while relying on dedicated email providers for delivery.
I also added rate limiting with Upstash Redis to protect the app from abuse. Login attempts are now limited to reduce brute-force attacks, and post creation has its own limits to help prevent spam.
One detail I found especially interesting was learning that even small implementation choices matter for security. For example, email sending shouldn't block the response because response timing can unintentionally leak information to attackers.
Building these features has been a great reminder that developing an application isn't just about adding functionality—it's also about making it secure, reliable, and resilient.
If you're learning too, don't skip the "behind-the-scenes" topics like security. They're what turn a working app into a production-ready one.
