Modern AI Generation UX 🎨

Features Implemented

1. Real-Time Progress Tracking

Shows elapsed time and dynamic messages during generation:

generationStartTime = signal<number | null>(null);
elapsedTime = signal<number>(0);

// Update every second
this.elapsedTimeInterval = setInterval(() => {
  if (this.generationStartTime()) {
    this.elapsedTime.set(
      Math.floor((Date.now() - this.generationStartTime()!) / 1000)
    );
  }
}, 1000);

Messages shown:

• "Analyzing your prompt..." (0-5s)
• "Generating widget code..." (5-15s)
• "Applying intelligent properties..." (15-20s)
• "Finalizing..." (20s+)

2. User-Controlled Cancellation

Users can stop generation at any time:

cancelGeneration(): void {
  this.isGenerating.set(false);
  this.generationCancelled = true;
  // Clear intervals, stop requests
}

UI:

<button (click)="cancelGeneration()" *ngIf="isGenerating()">
  Cancel Generation
</button>

3. Enhanced Error Messages

Specific, actionable error messages:

if (cancelled) {
  error = 'Generation cancelled by user';
} else if (timeout) {
  error = 'Generation took longer than expected. Try a simpler prompt.';
} else if (noResponse) {
  error = 'AI did not return a valid response. Please try again.';
}
