DJAlgoRhythm 🎵

🤖 The AI-Powered Chat-to-Spotify DJ Bot

Turn your group chat into a collaborative music experience

⚠️ DISCLAIMER

This is a vibe-coded passion project! 🚀

While DJAlgoRhythm works great for personal use and small groups, it was built with enthusiasm rather than enterprise-grade standards. Not recommended for production environments or critical applications. Use at your own risk and have fun with it!

🎯 What is DJAlgoRhythm?

DJAlgoRhythm transforms your group chat into an intelligent music curator. Simply drop a song name, artist, Spotify link, or even cross-platform music links (YouTube, Apple Music, Tidal, etc.) into your Telegram group, and watch as the bot automatically adds it to your shared Spotify playlist.

✨ The magic happens when someone says: "Play some Arctic Monkeys" and the AI figures out exactly which song they meant!

🔐 First Run: Spotify Authorization

On first startup, DJAlgoRhythm will guide you through Spotify OAuth:

The terminal will display an authorization URL
Open the URL in your browser
Log in to Spotify and click "Agree"
Your browser will redirect to 127.0.0.1:8080/callback with a success message
DJAlgoRhythm automatically receives the authorization and continues startup

No manual code copy-paste needed! The OAuth flow is fully automated with a temporary callback server.

🎉 Additional Setup: The app will automatically scan for Telegram groups and let you pick one!

Development Environment

The project uses devenv (Nix) for reproducible development:

# Enter development shell
devenv shell

# Available tools
devenv-help

# VS Code with extensions
code .

Included tools:

Go toolchain with delve debugger
golangci-lint for linting
Git LFS for large files
Claude Code extension for AI assistance

Building

# Build binary
make build

# Run tests
make test

# Run all quality checks (fmt, vet, lint, test, build)
make check

# Clean build artifacts
make clean

# Build Docker images (multi-platform: linux/amd64, linux/arm64)
make snapshot-release

Docker Build

The snapshot-release target uses GoReleaser to build multi-platform Docker images automatically:

Built platforms:

linux/amd64 - Linux x86_64
linux/arm64 - Linux ARM64 (Raspberry Pi, AWS Graviton, etc.)

What it does:

Builds Go binaries for all platforms (cross-compilation)
Creates Docker images for each platform
Tags images as djalgorhythm:latest
Uses GoReleaser configuration from .goreleaser.yml

No manual platform selection needed - GoReleaser handles everything automatically!

Testing

# Run all tests
go test ./...

# Run tests with coverage
go test -cover ./...

# Run tests with race detection
go test -race ./...

# Test specific package
go test ./internal/chat/telegram/

API Endpoints

Endpoint	Description
`GET /`	Service information and status
`GET /healthz`	Health check (liveness probe)
`GET /readyz`	Readiness check
`GET /metrics`	Prometheus metrics

Metrics

Key metrics exposed at /metrics:

djalgorhythm_playlist_size - Current playlist track count

Note: Additional metrics for message processing, LLM calls, errors, and active sessions are planned for future releases.

Deployment

Docker

# Run with environment file
docker run --env-file .env -p 8080:8080 enteee/djalgorhythm:latest

Production Considerations

Secrets: Use proper secret management (not .env files)
Monitoring: Set up Prometheus + Grafana dashboards
Logs: Forward structured logs to your logging system
Backup: Chat frontend sessions and Spotify tokens
Scaling: Single instance recommended (chat sessions are stateful)
Compliance: Be aware of chat platform ToS

Troubleshooting

Common Issues

Telegram Bot Setup:

# Check bot token is valid
curl "https://api.telegram.org/bot<TOKEN>/getMe"

# Verify bot is admin in group
# Check group ID is correct (negative number)

Spotify Authentication

# Verify redirect URI matches Spotify app settings
# Check client ID and secret are correct
# Ensure playlist ID is valid and accessible

LLM Errors

# Check API key is valid
# Verify model name is correct
# Monitor rate limits in logs

Debug Mode

# Enable debug logging
DJALGORHYTHM_LOG_LEVEL=debug ./bin/djalgorhythm

# Or with flag
./bin/djalgorhythm --log-level debug
