Project Setup

• Initialized project structure with directories: src/, public/, database/
• Created package.json with required dependencies:
  • express (web server)
  • sqlite3 (database)
  • node-telegram-bot-api (Telegram bot)
  • ytdl-core (YouTube downloads)
  • fluent-ffmpeg (MP3 conversion)
  • axios (HTTP requests)
• Set up SQLite database schema with tables:
  • users (telegram users)
  • search_history (user search queries)
  • downloads (converted files tracking)
• Initialized git repository

Completed Features

• Create Telegram Web App HTML interface
• Implement YouTube search functionality
• Add video thumbnail display
• Implement MP3 conversion with ffmpeg
• Set up Telegram bot integration
• Created configuration files (.env.example, .gitignore)
• Added comprehensive README with deployment instructions

Technical Implementation

• Frontend: Responsive Web App with Telegram Web App SDK integration
• Backend: Express.js server with RESTful API
• Database: SQLite with user management and search history
• YouTube: Custom search implementation with fallback methods
• Audio: FFmpeg-based MP3 conversion pipeline
• Bot: Full Telegram Bot API integration with inline queries

Files Created

• src/server.js - Main Express server with API endpoints
• src/bot.js - Telegram bot with commands and Web App integration
• src/youtube.js - YouTube search and audio stream extraction
• src/database.js - SQLite database management
• public/index.html - Web App interface
• public/style.css - Responsive CSS with Telegram theming
• public/script.js - Frontend JavaScript with Web App SDK
• Configuration and documentation files

Next Steps for Deployment

• Install FFmpeg on target server
• Set up environment variables
• Configure Telegram bot with BotFather
• Deploy to hosting platform (Docker with Traefik SSL)

TypeScript Migration

• Migrated entire project from JavaScript to TypeScript
• Added type definitions for all dependencies
• Created separate TypeScript configs for backend/frontend
• Updated build process and package.json scripts
• All files converted: server.ts, bot.ts, database.ts, soundcloud.ts, script.ts

Docker & Production Setup

• Complete Docker setup with multi-stage builds
• Traefik reverse proxy with automatic SSL (Let's Encrypt)
• GitHub Actions CI/CD with security scanning

Critical Issues Discovered

• YouTube integration completely blocked by bot detection
• Attempted multiple YouTube packages (play-dl, ytdl-core, youtube-dl-exec)
• All anonymous methods return 403 errors from YouTube
• SoundCloud integration attempted as replacement

SoundCloud Integration Failure

• Installed soundcloud-downloader package
• Created SoundCloudService class with proper error handling
• CRITICAL BUG FOUND: Frontend sends YouTube video IDs, backend expects SoundCloud IDs
• This architectural mismatch breaks the entire conversion flow

Current Status: BROKEN

• ❌ Music search: No working backend service
• ❌ MP3 conversion: Depends on working search
• ❌ Download functionality: Cannot find tracks
• ✅ Infrastructure: Telegram bot, database, Docker all working
• ✅ Frontend UI: Search interface functional
• ✅ TypeScript: Full type safety implemented

Alternative Sources Analysis

• Evaluated Archive.org, Jamendo, Bandcamp, Spotify
• Archive.org identified as most promising (largest free collection)
• NEXT: Implement Archive.org integration
• NEXT: Fix frontend-backend service mismatch
