Скачать или смотреть MERN Stack Lecture 3 — Secure Registration: bcryptjs Pre-save Middleware & JWT Authentication

In this video, we take our MERN authentication system to the next level 🚀
No more storing plain passwords — we’ll use bcryptjs with Mongoose pre-save middleware to hash them automatically. Plus, you’ll learn how to generate a JSON Web Token (JWT) with expiresIn for secure, time-limited login sessions.

✨ What you’ll learn today:
1️⃣ Why password hashing is a must for real-world apps
2️⃣ Implementing bcryptjs pre-save middleware in Mongoose
3️⃣ Register API with auto password hashing
4️⃣ Generate JWT token with payload & expiry time
5️⃣ Test everything step by step in Postman

👉 By the end of this lecture, you’ll have a professional-grade Register API that’s ready for production authentication.

💡 Next Lecture Preview: We’ll implement Login with JWT and protect private routes!
