RustifyDL

A fast, no-fuss Spotify downloader built in Rust.

Why RustifyDL?

Turn any Spotify track/album/playlist URL into properly tagged audio files. RustifyDL pairs Spotify metadata with audio from YouTube, then writes tidy tags and artwork so your library looks right everywhere.

Features

• ⚡ Concurrent downloads for maximum speed
• 🏷️ Accurate tags: artist, album, track/disc numbers, genre, year, cover art
• 🔇 Clean, minimal logging (tune with verbosity levels)
• 🧰 FFmpeg-based conversion (choose bitrate/format)
• 📚 Library and CLI - use as a Rust crate or standalone binary

Library Usage

Add to your Cargo.toml:

[dependencies]
rustifydl = "0.1"
tokio = { version = "1", features = ["full"] }

Example usage:

use rustifydl::{download_spotify, DownloadOptions};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error + Send + Sync>> {
    let opts = DownloadOptions {
        url: "https://open.spotify.com/album/xxxxxxxx".into(),
        client_id: "<your_spotify_client_id>".into(),
        client_secret: "<your_spotify_client_secret>".into(),
        output_dir: "./downloads".into(),
        concurrent_downloads: 6,
        no_dupes: true,
        bitrate: "192k".into(),
        format: "mp3".into(),
        verbosity: "info".into(),
        no_tag: false,
        timeout: 60,
    };
    
    download_spotify(opts).await?;
    Ok(())
}

Configuration (Automatic)

RustifyDL manages Spotify API credentials automatically. On first use it creates a config file and reuses it next time—no need to pass credentials on the command line.

Config location examples:

• Windows: %APPDATA%/RustifyDL/config.toml
• Linux: ~/.config/RustifyDL/config.toml
• macOS: ~/Library/Application Support/RustifyDL/config.toml

To reset, delete the file and run again.
