• Shared global CSS for styling
• Modular JavaScript files
• Application state managed via localStorage

---

🧱 Architecture Layers

🔹 UI Layer

• HTML (structure)
• CSS (layout, styling, responsiveness)

🔹 Logic Layer

• JavaScript handles:

  • Authentication simulation
  • Payment flows
  • UI updates

🔹 Data Layer

• localStorage acts as:

  • Session manager
  • Mock database

---

🔐 Authentication Module

Features

• Login & Signup pages
• OTP verification system
• Session persistence

Flow

1. User enters email & password
2. System validates (mock logic)
3. Random 6-digit OTP generated
4. OTP stored in localStorage
5. On success → Redirect to dashboard

---

🧠 State Management

Data Type	Storage Key
Session	isLoggedIn
OTP	otp
Transactions	transactions
Cards	cardState
Notifications	notifications

---

📦 JavaScript Modules

• auth.js → Authentication & OTP logic
• dashboard.js → Load balance & transactions
• payments.js → Payment simulation
• app.js → Global session handling

---

🔐 Security Simulation

if (localStorage.getItem("isLoggedIn") !== "true") {
  window.location.href = "login.html";
}

⚠️ This is only a frontend protection mechanism and not secure for production.

---

📱 Responsiveness

• Works on desktop and mobile devices
• Built using Flexbox layouts
• Adaptive components for different screen sizes

---

⚠️ Limitations

• No backend integration
• No real authentication system
• No encryption/security layers
• Data lost when localStorage is cleared

---

🔮 Future Enhancements

• Backend integration (Node.js / FastAPI)
• JWT or OAuth authentication
• Real payment gateway integration
• Database connectivity
• Advanced analytics dashboard
• Dark mode support

---

🎯 Purpose

NeoBank is designed to:

• Demonstrate fintech UI architecture
• Simulate banking workflows
• Provide a base for full-stack development

---

🏁 Conclusion

NeoBank is a complete frontend simulation of a banking system that showcases how real-world financial applications are structured.

Final Outcome:

• Structured banking UI
• Simulated transaction system
• Modular frontend architecture
• Backend-ready design
