Project 1 — Advanced Admin Dashboard (Real-World Architecture)

🧭 Introduction

Now that you’ve mastered:

• Advanced hooks
• State management
• Authentication & RBAC
• Error handling
• Testing
• TypeScript

It’s time to combine everything into a real, production-style project.

This project is designed to simulate how enterprise React dashboards are actually built in companies.

⚠️ This is not a toy project
This is a career-grade React project

🎯 Project Goals

By completing this project, you will learn how to:

• Design a scalable React architecture
• Implement authentication & role-based access
• Build protected admin routes
• Manage global state properly
• Handle APIs, loading, and errors
• Apply performance optimizations
• Structure a real production app

🧠 What We Are Building

✅ Advanced Admin Dashboard

Features include:

• Login & Logout
• Role-based access (Admin / Manager / User)
• Protected routes
• Dashboard layout (Sidebar + Header)
• User management (CRUD)
• API integration
• Global error handling
• Loading states
• Reusable components
• TypeScript everywhere

└── types/              → TypeScript types

This is a feature-first, scalable structure.

🔐 Authentication & RBAC (Core Feature)

Roles

• admin → Full access
• manager → Limited admin access
• user → Read-only

Protected Routes

<RoleProtectedRoute allowedRoles={["admin"]}>
  <UsersPage />
</RoleProtectedRoute>

🧩 Dashboard Layout

Layout Structure

• Sidebar navigation
• Top header (user info + logout)
• Content area

<DashboardLayout>
  <Outlet />
</DashboardLayout>

✔ Reusable
✔ Clean
✔ Easy to extend

👥 User Management Module (CRUD)

Features

• List users
• Add user
• Edit user
• Delete user (admin only)

API Layer (Centralized)

export const getUsers = () =>
  apiClient<User[]>("/users");

No API logic inside components.

🧠 State Management Strategy

This avoids overusing Redux.

⚡ Performance Optimizations Used

• React.memo for heavy components
• useCallback for handlers
• Code splitting for routes
• Lazy-loaded pages

const UsersPage = React.lazy(() => import("./Users"));

🛡️ Error Handling Strategy

• Error Boundaries at layout level
• Global error banner for API errors
• Graceful fallbacks

<ErrorBoundary>
  <DashboardLayout />
</ErrorBoundary>

🧪 Testing Strategy (Applied)

• Component tests for forms
• API mocking for user list
• RBAC behavior tests

Example:

expect(screen.getByText("Access Denied"))
  .toBeInTheDocument();

🔷 TypeScript Usage

• Typed API responses
• Typed context
• Typed routes & props

No any allowed 🚫

📦 Reusable Components Built

• Button
• Modal
• Table
• Loader
• ErrorBanner

These components can be reused in any future project.
