🎯 Purpose

This PR adds comprehensive debugging tools to investigate why RemixHookForm stories work in yarn dev but fail in yarn serve (static builds) with the error:

TypeError: Cannot read properties of null (reading 'handleSubmit')

🔧 Changes Made

1. Enhanced Textarea Story (textarea.stories.tsx)

  • Added FormContextDebugger component with real-time context monitoring
  • Visual debug panel showing context availability over time
  • Console logging for detailed context state tracking

2. Enhanced TextField Story (text-field.stories.tsx)

  • Added DebugWrapper component with timing analysis
  • Checks context availability at multiple intervals (0ms, 100ms, 500ms, 1s, 2s)
  • Tracks when context becomes available after component mount

3. New Comparison Story (context-debug-comparison.stories.tsx)

  • Side-by-side comparison of working vs broken patterns
  • Working Pattern: Direct DOM elements with methods.register()
  • Broken Pattern: Form components using useRemixFormContext()
  • Real-time context monitoring for both approaches

🔍 Debug Features

  • Visual Indicators: Color-coded debug panels (green=working, red=broken, yellow=checking)
  • Console Logging: Detailed context state information in browser console
  • Timing Analysis: Track exactly when context becomes available/null
  • Real-time Monitoring: Continuous context status updates

🧪 Testing Instructions

  1. Development Mode: yarn dev - Both patterns should work
  2. Static Build: yarn build-storybook && yarn serve - Only working pattern should work
  3. Check Console: Look for detailed context debugging information
  4. Visual Debug: Watch the debug panels for real-time status

🎯 Expected Findings

This will help us identify:

  • When the context becomes null in static builds
  • Why direct DOM elements work but components fail
  • Timing issues with context initialization
  • Provider/consumer relationship problems

📋 Related Issues

  • Textarea Customized story ✅ works (uses direct DOM)
  • All other RemixHookForm stories ❌ broken (use form components)
  • Issue only occurs in static builds, not development

Next Steps: Once we identify the root cause, we can implement a proper fix for the context initialization timing issue.


💻 View my workAbout Codegen

- Add FormContextDebugger to textarea.stories.tsx with real-time context monitoring
- Add DebugWrapper to text-field.stories.tsx with timing analysis
- Create context-debug-comparison.stories.tsx for side-by-side comparison
- Add console logging to track when context becomes available/null
- Compare working pattern (direct DOM) vs broken pattern (components)

This will help identify why form context is missing in static builds but works in dev.
