About This Episode:
Your app just got a voice 💬✨
It’s time to give your users clear feedback with flash messages — those friendly pop-ups that say things like “User created” or “Access denied.”
In this episode, we’ll bring interactivity and state together to create a polished, professional experience.
👉 In this episode, you’ll learn how to:
🚀 Implement flash messages using your existing session system
⚙️ Build alert helpers (req.alert.success, req.alert.error, req.alert.warn)
🧩 Pass flash data into your EJS views for dynamic display
💡 Automatically clear messages after they’re shown
🎨 Create a reusable _flash.ejs component for consistent UX
By the end, your Node.js app will communicate like a pro — giving users instant, elegant feedback ⚡️
