Why

Why I built it

I wanted to build a production-grade full-stack app with MERN stack along Typescript with real-world features: complete complex authentication, user and link management, file uploads, analytics and dynamic SEO.

Features

Core features

Secure sign-in

Email and password, or Google and GitHub, with rotating JWT tokens.

Account safety

Email verification, password reset and a 7-day link to undo an unauthorized email change.

Links, your way

Ready-made social links plus custom ones, and an avatar upload.

Make it yours

Colors, fonts, button styles and layouts, with dark and light mode.

Deep dive

A closer look

problem

Changing an account's email is a common way to take it over.

solution

The old address gets a special link that reverts the change. The attacker's email is deleted, and email changes stay locked for 7 days.

insight

Security is mostly small decisions. Hashed tokens and uniform error responses cost little to add, but they limit what an attacker can learn.
