🚀 Day-18 — CORS Setup, React CRUD Integration & Password Encryption (bcryptjs) | MERN Bangla

Welcome back to the MERN Stack Full Course Bangla (Backend Edition)!
This is Day-18, where we connect frontend with backend and introduce security basics in APIs.

In this class, you’ll enable cross-origin communication, integrate your React app with Express APIs, and secure user data using password encryption.

What you’ll learn in this video:
Installing and configuring CORS in Express
Enabling cross-origin requests between React and backend
Connecting React frontend with CRUD APIs
Sending data from React to Express server
Password encryption using bcryptjs
Password comparison (decryption logic) during login
Real-world examples of secure authentication flow

This class bridges the gap between frontend and backend while introducing industry-level security practices.

By the end of this video, you’ll be able to connect your full stack app and securely handle user passwords.
