A client-side web application that polls HTTP endpoints and displays JSON responses in a console-like interface using XMLHttpRequest.

• HTTP Polling: Continuously fetch JSON data from any HTTP endpoint (defaults to http://127.0.0.1:8080)
• Configurable Interval: Adjust polling frequency from 100ms to 10 seconds
• JSON Response Display: Automatically formats and displays HTTP responses
• Console Interface: Terminal-style dark theme with timestamped, color-coded messages
• Request Management: Start/stop polling controls with real-time status indicators
• Statistics Tracking: Counts total requests and errors
• Error Handling: Comprehensive HTTP error handling with status codes
• Clear Console: Reset the message display at any time

1. Open the web application
2. Enter your HTTP endpoint URL (default: http://127.0.0.1:8080)
3. Set the polling interval in milliseconds (default: 1000ms)
4. Click "Start" to begin polling the endpoint
5. JSON responses will be displayed in real-time in the console
6. Use "Clear" to reset the console or "Stop" to halt polling

• Frontend: Pure HTML/CSS/JavaScript with TailwindCSS for styling
• Backend: Hono server for serving static files
• HTTP Client: Native browser XMLHttpRequest API
• Polling: Configurable interval-based requests
• Error Handling: HTTP status codes, network errors, and timeouts
• Timeout: 5-second request timeout to prevent hanging
• Responsive Design: Works on desktop and mobile devices

The application runs entirely client-side once loaded, making HTTP requests directly from the browser to your specified endpoint.
