Day 171 of Learning MERN Stack

Hello Dev Community! 👋

It is officially Day 171 of my full-stack web development journey, and I am thrilled to announce that QuickChat (MERN Stack Real-Time Chat App) is officially complete! 🎉🚀

Today, I finalized the last key security layer: JWT Authentication & Route Protection Middleware.

🛠️ Technical Breakdown: JWT Route Security

As captured in my implementation snapshots (auth.js & utils.js):

1. Token Signature Utility (utils.js)

• Configured a centralized token generator helper signing payload userId parameters using environment secrets:

javascript
  const generateToken = (userId) => {
    return jwt.sign({ userId }, process.env.JWT_SECRET);
  };
