Creating modern, scalable dashboards requires a thoughtful combination of frontend technologies and architectural patterns. In this article, we explore how Dashboard Example utilizes Next.js 15, Redux Toolkit, TanStack Table, and shadcn/ui to deliver a fast, maintainable, and feature-rich admin panel.

The application fetches data from JSONPlaceholder, a free online REST API used for prototyping and testing.

This project showcases a clean architecture and focuses on modularity, developer experience, and performance — ideal for real-world applications like CMS dashboards, admin panels, or data-driven UIs.

Technology Stack

Core Frameworks

  • Next.js 15 Provides hybrid rendering (SSR/SSG), dynamic routing, and powerful app routing via the /app directory.
  • React 19 The latest version enhances concurrent rendering and delivers better performance with features like automatic batching and useOptimistic.
  • TypeScript Adds static type safety, reducing runtime bugs and improving development efficiency.
  • Redux Toolkit (RTK Query) Handles global state and API data fetching with minimal boilerplate. RTK Query simplifies caching, re-fetching, and data synchronization.

UI and Styling

  • Tailwind CSS A utility-first CSS framework for consistent styling and rapid prototyping.
  • shadcn/ui A beautiful, accessible component library built on top of Radix UI and styled with Tailwind. It's highly composable and ideal for modern UIs.
  • TanStack Table A powerful headless table solution that supports sorting, pagination, filtering, and virtualization. Perfect for building responsive and interactive tables.

Project Structure

The codebase follows a modular and scalable structure:

├── app/              # App router directory (Next.js 15)
│   ├── albums/       # Feature-based routes
│   ├── posts/
│   ├── todos/
│   └── users/
├── components/       # Shared React components
│   ├── ui/
├── hooks/            # Custom hooks
├── lib/              # Utility functions and helper modules
│   ├── features/
│   ├── interfaces/
├── public/           # Static files (e.g., images, icons)

This organization enables code splitting, maintainability, and logical feature boundaries. Each route in the app/ directory can have its own loading state, error handling, and layout, thanks to the new Next.js app router.

Key Features

1. RTK Query for API Calls

RTK Query handles all CRUD operations with endpoints like /users, /posts, and /albums, automatically caching responses and minimizing network requests.

const { data: users, isLoading } = useGetUsersQuery();

2. Pagination and Filtering with TanStack Table

Every data table in the app (e.g., users, albums) is powered by TanStack Table. This allows:

  • Client-side pagination
  • Column sorting and filtering
  • Responsive layouts with Tailwind
<UsersTable data={users} columns={columns} />

3. Reusable Components with Shadcn/UI

Components like buttons, cards, dropdowns, and modals are built using shadcn/ui, offering consistent styling and accessibility out of the box.

import { Button } from "@/components/ui/button";

<Button variant="outline">Add User</Button>

Conclusion

This project highlights how combining Next.js 15, RTK Query, TanStack Table, and shadcn/ui results in a robust dashboard solution that is:

  • Highly maintainable
  • Scalable
  • Developer-friendly
  • Visually consistent and performant

Whether you're building an admin panel, internal tool, or data-heavy SPA, this stack offers everything you need to get started quickly without sacrificing long-term maintainability.
