A single-file HTML application that allows you to analyze entire folders of files using Large Language Models (LLM). Upload a folder, ask questions, and get AI-powered insights across all your files. Part of a 3-stage loading architecture for maximum reliability.

Package Exports

  • @kosmas10/folder-llm-analyzer
  • @kosmas10/folder-llm-analyzer/folder-llm-analyzer.html

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@kosmas10/folder-llm-analyzer) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Version: 0.0.3
Package: @kosmas10/folder-llm-analyzer

🏗️ Architecture: 3-Stage Loading System

This application uses an innovative 3-stage loading architecture designed for maximum reliability and flexibility:

Stage 1: Bootstrap (User Installs This)

  • File: folder-llm-analyzer-bootstrap.html
  • Purpose: Ultra-minimal loader that NEVER changes
  • Size: ~2KB
  • What it does: Loads Stage 2 from npm/CDN

Stage 2: Loader (Auto-Updates)

  • Package: @kosmas10/html-app-loader
  • Purpose: Sophisticated HTML app loader
  • What it does: Handles complex loading logic, can be updated via npm

Stage 3: Application (Auto-Updates)

  • Package: @kosmas10/folder-llm-analyzer (this package)
  • Purpose: The actual Folder LLM Analyzer application
  • What it does: Provides the full folder analysis experience

Why This Architecture?

  1. 🛡️ Future-Proof: Stage 1 never changes, so users never need to update their local file
  2. 🔄 Auto-Updates: Stages 2 & 3 update automatically via npm/CDN
  3. 🐛 Bug Fixes: Loader bugs can be fixed without user intervention
  4. 📦 Flexible: Can adapt to new requirements without breaking existing installations

🚀 Quick Start

  2. Open it in your browser:

    • Double-click the file, or
    • Open it from your browser's File menu

  3. That's it! The application will load automatically and stay up-to-date.
