LARC HTML Files Audit Report

Date: November 13, 2025 Purpose: Verify correct pan-bus instantiation and script paths

Summary

Total HTML files found: 125
Files audited: Key files (playground, root, test files)
Status: ✅ Core playground files are correct
Issues Found: See details below

✅ PLAYGROUND (Primary Focus)

`/playground/index.html`

Status: ✅ CORRECT Pan-bus Setup:

✅ Has element at end of body
✅ Inline module script imports pan-bus conditionally
✅ Path: ../core/pan-bus.mjs ← CORRECT
✅ Then imports ./playground.mjs ← CORRECT

All Script Paths Verified:

✅ ./styles/playground.css exists
✅ ./playground.mjs exists
✅ ../core/pan-bus.mjs exists

Components Used:

← Loaded by playground.mjs
← Loaded by playground.mjs
← Loaded by playground.mjs
← Loaded by playground.mjs
← Loaded by playground.mjs

Verdict: Ready for use. All paths resolve correctly.

Submodule Directories

`/core/` - Core Pan-bus Implementation

Contains: pan-bus.mjs
Status: ✅ File exists and is the source for playground

`/components/` - Component Library

Contains: src/components/ with 49 components
Status: ✅ All 36 components with pan-client imports fixed
Import path: ../../../core/pan-client.mjs

`/examples/` - Example Applications

Status: ✅ All paths fixed and verified (36 files updated)
Note: Examples directory is a git submodule with its own repo
Fixed patterns:

- All ./src/pan.js → ../core/pan-bus.mjs - All ../src/pan.js → ../../core/pan-bus.mjs - All ../../src/pan.js → ../../../core/pan-bus.mjs - All pan-client imports updated to correct relative paths - Added missing elements to 24 HTML files

Committed to examples submodule: ab2d792

Key Path Patterns

Correct Import Patterns

From /playground/index.html:

import('../core/pan-bus.mjs')  // ✅ Correct
import('./playground.mjs')                      // ✅ Correct

From /playground/components/pg-canvas.mjs:

import('../../components/pan-card.mjs')  // ✅ Correct

From /components/pan-card.mjs:

import('../../../core/pan-client.mjs')  // ✅ Correct (Fixed)

Pan-bus Element Usage

Correct Pattern:

<script type="module">
  // Load pan-bus module first
  if (!customElements.get('pan-bus')) {
    await import('../core/pan-bus.mjs');
  }
  // Then load your app
  await import('./your-app.mjs');
</script>
<!-- Pan-bus element in body -->
<pan-bus debug="true"></pan-bus>

Issues Fixed During Development

❌ Pan-bus Double Registration

- Fixed: Line 697 trying to register same constructor twice - Solution: Removed pan-bus-enhanced duplicate registration

❌ Wrong pan-client Import Path (36 files in components/)

- Was: ./pan-client.mjs (wrong directory) - Fixed: ../../../core/pan-client.mjs - Files affected: 36 component files

❌ Wrong pan-client Import Path (30+ files in examples/)

- Was: Various wrong paths like ./, ../, etc. - Fixed: Correct relative paths to core/pan-client.mjs - Files affected: 36 files in examples directory

❌ Wrong pan-bus Script Tags (20+ files in examples/)

- Was:
