📁 Features

🔐 Authentication

• User login system with encrypted passwords (bcrypt)
• JWT tokens are issued on login and stored in cookies
• Middleware verifies token for protected routes

👤 User Features

• Create a new user
• Prevent duplicate user creation if a user is already logged in

📝 Post Management

• Create a post with:
  • Title
  • Description
  • Optional Image URL
  • Like count (defaults to 0)
  • Date (automatically generated)
• Each post is tied to the authenticated user

🔒 Middleware Protection

• A middleware checks if the JWT token exists and is valid
• Blocks access to protected routes if the user is not authenticated
• Clears expired or invalid tokens and redirects to login
