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
