Building Real-time Dashboards

Create responsive real-time dashboards that update instantly as data changes without page refreshes.

Real-time Technologies Comparison

Technology	Best For	Complexity
WebSockets	Bi-directional communication	High
Server-Sent Events	Server-to-client updates	Medium
HTTP Long Polling	Simple implementations	Low

Architecture Patterns

Choose the right pattern for your needs:

• Pub/Sub with Redis
• Database change data capture
• Message queue integration
• Edge computing push notifications

React State Management

Optimize updates with:

// Using SWR for real-time data
import useSWR from 'swr'

function Dashboard() {
  const { data, error } = useSWR('/api/metrics', 
    fetcher, { refreshInterval: 1000 })
  
  return 
}

Visualization Techniques

• Smooth animations with React Spring
• Canvas-based rendering for high-frequency updates
• Virtualized lists for large datasets
• Throttling and debouncing strategies

Build dashboards that handle thousands of updates per second with sub-100ms latency.
