feat: Add react-joyride guided walkthrough for first-time users

[nadimtuhin]

Implements issue #10

Adds a comprehensive guided walkthrough using react-joyride for first-time users with localStorage state management.

Features:

• 🎯 Guided tour with 7 steps highlighting key UI elements
• 💾 localStorage persistence for tour completion status
• ⌨️ Manual tour trigger via ⌘⇧? keyboard shortcut
• 🎨 Seamless integration with existing UI
• 📚 Updated keyboard shortcuts documentation

Technical Details:

• Added react-joyride and TypeScript types
• Created reusable GuidedTour component with useShouldShowTour hook
• Added data-tour attributes to key UI elements
• Tour automatically shows for first-time users after 1s delay

Code Review Complete ✅

Reviewed the react-joyride guided walkthrough implementation. Overall, this is a well-structured feature with good TypeScript usage and React patterns. Here are my findings:

🟢 Code Quality & Best Practices

Strengths:

• Strong TypeScript usage: Proper interfaces (GuidedTourProps, well-typed react-joyride imports)
• Good component separation: Custom hook useShouldShowTour cleanly separates tour logic
• Consistent styling: Uses existing Tailwind classes and design patterns
• Accessibility: Good keyboard navigation support and ARIA-friendly structure

Minor improvements:

• Consider extracting tour steps to a separate config file for maintainability (src/components/GuidedTour.tsx:11-47)

🟡 Potential Bugs & Issues

Critical:

1. Race condition in tour initialization (src/components/GuidedTour.tsx:120-128):

   // Current code has potential timing issue
   const timer = setTimeout(() => {
     setShouldShow(true);
   }, 1000);

   Fix: Add DOM ready check or use requestAnimationFrame to ensure elements exist

2. Missing error handling for localStorage (src/components/GuidedTour.tsx:67):

   localStorage.setItem(TOUR_STORAGE_KEY, 'true'); // No try/catch

   Fix: Wrap in try/catch for incognito/storage-disabled browsers

Minor:
3. Keyboard event cleanup dependency (src/App.tsx:250): Missing setShowTour in useEffect dependency array
4. Tour target validation: No verification that data-tour elements exist before starting tour

⚡ Performance Considerations

Good:

• Proper event listener cleanup (src/App.tsx:248-250)
• Conditional rendering of tour component

Optimizations:

• localStorage access on every render: Move hasCompletedTour check to ref or memo
• Multiple keyboard listeners: Consider consolidating into single handler
• Tour delay: 1000ms delay seems reasonable for UX

🔒 Security Assessment

✅ No major security concerns:

• localStorage usage is standard and safe
• Tour content is static (no user input or external content)
• No XSS vectors identified
• Proper event handling without eval or innerHTML

❌ Test Coverage

Missing test coverage for:

• Tour flow and step progression
• Keyboard shortcut functionality (⌘⇧? trigger)
• localStorage persistence behavior
• Hook state management (useShouldShowTour)
• Error scenarios (missing DOM elements, localStorage failures)

Recommended test files:

src/components/__tests__/GuidedTour.test.tsx
src/components/__tests__/useShouldShowTour.test.tsx

📋 Recommendations

High Priority:

1. Add error handling for localStorage operations
2. Fix useEffect dependency in src/App.tsx:250
3. Add basic test coverage for tour functionality

Medium Priority:

4. Validate tour targets exist before starting
5. Extract tour configuration to separate file
6. Add loading state for tour initialization

Low Priority:

7. Consider tour analytics (optional, for usage insights)
8. Add tour version management for future updates

🎯 Overall Assessment

This is a solid implementation that follows React best practices and provides good UX. The code is clean, well-typed, and integrates seamlessly with the existing codebase. Main concerns are around error handling and test coverage rather than fundamental issues.

Recommendation: ✅ Approve with minor fixes
