In an era where AI writes code nobody understands — this was built line by line, concept by concept, from scratch.
A complete, production-grade REST API for user authentication. Not a tutorial copy. Not AI-generated. Every decision has a reason. Every line has an understanding.
What it covers:
Register · Login · Logout · Forgot Password · Reset Password JWT Tokens · httpOnly Cookies · bcrypt Hashing · Email Notifications Protected Routes · Rate Limiting · Full Error Handling
Stack:
Node.js · Express · MongoDB · JWT · bcryptjs · Nodemailer · Mailtrap
