# TASK-006 Changelog

## Overview

This file tracks all changes made during TASK-006: Fix Custom Font Loading in Editor Preview.

**Problem**: Custom fonts don't load in editor preview due to dev server not serving project directory assets.

**Solution**: (To be documented as implementation progresses)

## Changes

### [December 15, 2024] - Session 1 - Cline AI Assistant

**Summary**: Fixed custom font loading in editor preview by adding missing MIME types to web server configuration. The issue was simpler than expected - the server was already serving project files, but was missing MIME type mappings for modern font formats.

**Files Modified**:
- `packages/noodl-editor/src/main/src/web-server.js` - Added MIME type mappings for all font formats and fixed audio fallthrough bug
  - Added `.otf` → `font/otf`
  - Added `.woff` → `font/woff`
  - Added `.woff2` → `font/woff2`
  - Fixed `.wav` case missing `break;` statement (was falling through to `.mp4`)

**Testing Notes**:
- New projects: Fonts load correctly ✅
- Legacy projects: Fonts still failing (needs investigation)

### [December 15, 2024] - Session 2 - Cline AI Assistant

**Summary**: Added font fallback mechanism to handle legacy projects that may store font paths differently. The issue was that legacy projects might store fontFamily as just the filename (e.g., `Inter-Regular.ttf`) while new projects store the full relative path (e.g., `fonts/Inter-Regular.ttf`).

**Files Modified**:
- `packages/noodl-editor/src/main/src/web-server.js` - Added font fallback path resolution
  - When a font file isn't found at the requested path, the server now searches common locations:
    1. `/fonts{originalPath}` - prepend fonts folder
    2. `/fonts/{filename}` - fonts folder + just filename
    3. `/{filename}` - project root level
    4. `/assets/fonts/{filename}` - assets/fonts folder
  - Added console logging for fallback resolution debugging
  - Fixed ESLint unused variable error in `server.on('listening')` callback

**Technical Details**:
- Font path resolution flow:
  1. First tries exact path: `projectDirectory + requestPath`
  2. If not found and it's a font file (.ttf, .otf, .woff, .woff2), tries fallback locations
  3. Logs successful fallback resolutions to console for debugging
  4. Returns 404 only if all fallback paths fail

**Breaking Changes**:
- None - this enhancement only adds fallback behavior when files aren't found

**Testing Notes**:
- Requires rebuild and restart of editor
- Check console for "Font fallback:" messages to verify mechanism is working
- Test with legacy projects that have fonts in various locations
