Songy

Music quiz application with Spotify integration built with Phoenix Framework.

Requirements

• Nix (flakes enabled)
• direnv + nix-direnv (optional, for automatic environment activation)

Setup

1. Install Nix

sh <(curl -L https://nixos.org/nix/install)

2. Enable flakes

mkdir -p ~/.config/nix
printf "experimental-features = nix-command flakes\n" >> ~/.config/nix/nix.conf

3. (Optional) Install direnv and nix-direnv

For automatic environment activation when entering the project directory:

# Install direnv
nix profile add nixpkgs#direnv

# Install nix-direnv
nix profile add nixpkgs#nix-direnv

# Configure nix-direnv hook
mkdir -p ~/.config/direnv
echo 'source $HOME/.nix-profile/share/nix-direnv/direnvrc' >> ~/.config/direnv/direnvrc

# Add direnv hook to shell (bash, for other shells see https://direnv.net/docs/hook.html)
echo 'eval "$(direnv hook bash)"' >> ~/.bashrc

4. Clone the repository

5. Start development

With direnv (automatic):

cd songy/
direnv allow
# Environment automatically activated
mix setup
mix phx.server

Without direnv (manual):

cd songy/
nix develop
mix setup
mix phx.server

Now you can visit localhost:4000 from your browser.

Music Providers

By default, the app uses iTunes (no configuration needed) - its rate limits are sufficient for development.

For production or enhanced features, configure one of these providers:

Spotify

1. Go to Spotify Developer Dashboard

2. Create a new app

3. Add http://localhost:4000/auth/spotify/callback to redirect URIs

4. Set environment variables:

   SPOTIFY_CLIENT_ID=your_client_id
   SPOTIFY_SECRET_KEY=your_client_secret
   

Apple Music

Requires Apple Music API developer token:

APPLE_MUSIC_ACCESS_TOKEN=your_access_token
