About this project

A modern blockchain dashboard that showcases the power of PAPI for interacting with the Polkadot network. The application provides real-time block monitoring, network metrics, and interactive blockchain data visualization.

Key Features

  • Real-time Updates: Live block feed with smooth animations and instant updates.
  • Blockchain Metrics: Monitor finalized block numbers and calculate average block time.
  • WebSocket Integration: Persistent WebSocket connection with automatic reconnection handling.
  • Reactive Subscriptions: Utilizing observables for efficient real-time data stream management.
  • Performance Optimized: Reduced bundle size and efficient memory management for a smooth experience.

Challenges

The biggest challenge was efficiently handling frequent blockchain data updates while maintaining a responsive user interface. Implementing automatic reconnections and managing connection state also required careful consideration.

Learnings

This project helped me master PAPI and reactive programming concepts. I learned the importance of efficient WebSocket connection management and performance optimization strategies for real-time applications.
