Diagnose Runtime Issues

Quickly diagnose runtime performance issues in web applications including freezes, hangs, memory leaks, and slow performance.

What to analyze

Please specify what you need to diagnose:

1. Provide the URL: The web application URL to analyze
2. Describe symptoms (optional):
   • App freezes or becomes unresponsive
   • High memory usage or memory leaks
   • Slow performance or laggy interactions
   • Browser tab crashes
   • Specific user actions that trigger issues
3. Authentication (if needed): Provide auth token or credentials

Analysis approach

I'll use the web-performance-agent to:

1. Quick Diagnosis: Rapid scan for common issues

   • Memory leaks
   • Main thread blocking
   • Network bottlenecks
   • JavaScript errors

2. Framework Detection: Identify and apply framework-specific debugging

   • Angular: Zone.js and change detection issues
   • React: Re-render and state management problems
   • Vue: Reactive system and watcher issues

3. Deep Analysis (if needed):

   • CPU profiling to find hot functions
   • Heap snapshots for memory analysis
   • Network request monitoring
   • Long task detection

4. Provide Solutions:

   • Immediate fixes to try
   • Code examples for optimization
   • Architecture recommendations
   • Best practices to follow

Example usage

/diagnose-runtime https://example.com/app

Or with more details:

/diagnose-runtime https://example.com/app "The app freezes after clicking the submit button"

Or with authentication:

/diagnose-runtime https://example.com/app "token: abc123xyz"

What I'll provide

• Root cause analysis of the performance issue
• Evidence with metrics and measurements
• Immediate actions to resolve the problem
• Long-term solutions for prevention
• Specific code fixes when applicable

Let's diagnose your runtime performance issues!
