Performance-Heavy Admin Dashboard
High-performance admin dashboard built to handle massive datasets, real-time metrics, and secure role-based access.
Overview
This project is a fully performance-optimized admin dashboard designed to manage large-scale data in real time. It features a virtualized table capable of rendering 10,000+ rows without lag, advanced server-side filtering, real-time metric updates via WebSockets, and secure role-based access. Developed using Next.js App Router, the dashboard focuses on speed, scalability, and clean architecture.
Problem Statement
Modern admin dashboards often struggle with:
This project addresses all of these challenges head-on with a performance-first approach.
Goals & Requirements
Primary Goals
Render 10,000+ rows without lag using virtualization.
Provide real-time metric updates via WebSockets.
Implement secure role-based access control (RBAC).
Ensure smooth filtering, sorting, and pagination.
Tech Requirements
60 FPS scroll performance
Minimal bundle size and code splitting
Responsive design for mobile and desktop
Accessible UI components
Key Features
Ultra-Fast Virtualized Table
Implemented using TanStack Table + React Virtual for windowed rendering. Supports 10k+ rows, sticky header, column resize, and row selection.
Real-Time Metrics
Live CPU, request/sec, and active users streamed over WebSockets and visualized with lightweight charts.
Role-Based Access Control
JWT authentication with server-side middleware enforcing RBAC for protected routes and components.
Skeleton & Shimmer Loading
Custom shimmer rows and page-level skeletons to improve perceived performance during data fetches.
Architecture
The application follows a modular frontend architecture with clear separation between UI components, state management, and data access layers. Zustand manages client state while Next.js API routes handle data operations and WebSocket connections.

Backend
Performance Optimizations
Windowed rendering with React Virtual
Memoized cell renderers and column definitions
Debounced search and filter inputs
Dynamic imports for charts and heavy components
Server-side pagination and cached API responses
UI / UX
Focused on clarity and responsiveness: a compact sidebar, a top navigation bar with quick actions, and responsive tables that adapt to smaller screens without losing usability.

What I Learned
Designing for performance is often a cross-cutting concern across UI, APIs, and state management.
Zustand is excellent for small, focused state slices and avoids prop drilling.
Real-time systems require careful batching and throttling to avoid UI overwhelm.
