TablixJS jQuery Bundle Constructor Error Fix

Problem Summary

The jQuery bundled version (tablix.jquery.js) was experiencing a constructor error where users got:

TypeError: TablixJS.Table is not a constructor

This occurred because the jQuery wrapper was trying to access the global TablixJS.Table class before it was properly exposed in the UMD bundle execution order.

Root Cause

1. Execution Order Issue: In the UMD bundle, ES6 import hoisting caused the jQuery wrapper to execute before global variables were set
2. Global Dependency: The original jQuery wrapper relied on window.TablixJS being available
3. Timing Problem: jQuery wrapper checked for Table class availability before the bundle had finished exposing it globally

Solution Implemented

1. Created Bundled-Specific jQuery Wrapper

• File: src/jquery/tablixjs-jquery-bundled.js
• Approach: Direct Table class import instead of global dependency
• Key Change: import Table from '../core/Table.js' instead of checking window.TablixJS

2. Function-Based Initialization

• Pattern: Exported initializeJQueryWrapper() function
• Benefit: Explicit control over when jQuery plugin registration occurs
• Result: No more reliance on global variable timing

3. Updated Bundle Entry Point

• File: src/jquery/index.js
• Change: Import and call initializeJQueryWrapper() function
• Result: Guaranteed execution order regardless of ES6 import hoisting

Files Changed

1. src/jquery/tablixjs-jquery-bundled.js (New)

   • Direct Table class import
   • Function-based jQuery plugin registration
   • No global dependencies

2. src/jquery/index.js (Modified)

   • Import bundled wrapper function
   • Explicit function call to ensure execution
   • Maintained global exposure for compatibility

Verification

The fix has been verified with:

• ✅ Function-based initialization present
• ✅ Direct Table class instantiation
• ✅ No global dependency error checks
• ✅ jQuery plugin registration working
• ✅ Bundle size increase minimal (~600 characters)

Testing

1. Automated: node test/verify-jquery-bundle.js
2. Browser: Open examples/jquery-bundle-fix-test.html
3. Console: Should see "TablixJS jQuery plugin initialized successfully (bundled version)"

Benefits

1. Eliminates Constructor Errors: Direct Table class access prevents timing issues
2. Maintains Compatibility: All existing jQuery plugin APIs work unchanged
3. Preserves Performance: Minimal bundle size impact
4. Future-Proof: No longer dependent on global variable timing

Usage Unchanged

Users can continue using the jQuery plugin exactly as before:

// Bundled version usage (FIXED)
$('#table').tablixJS({
  data: myData,
  pagination: { enabled: true }
});

The fix is transparent to end users - no API changes required.
