ytsave

A simple and powerful Node.js tool to download YouTube videos and playlists with ease.
Works both as a CLI tool and as a library. 🎥🎶

✨ Features

• 📥 Download single YouTube videos
• 🎵 Download entire playlists in one command
• 🔊 Support for both audio-only (mp3) and video (mp4) formats
• ⚡ Fast & reliable (powered by yt-dlp)
• 🛠 Usable both as a CLI and as a library

🚀 Installation

As CLI (global)

npm install -g ytsave
`

As dependency (library usage)

npm install ytsave

📥 Install yt-dlp & ffmpeg

ytsave relies on the external tool yt-dlp to download media and (optionally) ffmpeg to merge separate video/audio streams. Install them on your system and ensure they're available on your PATH before running the CLI.

Windows

• Using winget:

  winget install yt-dlp
  

• Using pip (if Python is installed):

  pip install yt-dlp
  

• Using Scoop:

  scoop install yt-dlp
  

• Using Chocolatey:

  choco install yt-dlp
  

• Or download the yt-dlp.exe from the releases page and add it to your PATH: https://github.com/yt-dlp/yt-dlp/releases

macOS

• Using Homebrew:

  brew install yt-dlp
  

Linux

• Using pip:

  pip3 install --user yt-dlp
  

• Using your distro package manager (if available) or download the binary from the releases page.

ffmpeg (optional but recommended)

• ffmpeg is required if yt-dlp needs to merge separate video and audio streams (this happens when selecting the best video and best audio). Install ffmpeg via your platform package manager:
  • Windows (scoop/choco) — scoop install ffmpeg or choco install ffmpeg
  • macOS (Homebrew) — brew install ffmpeg
  • Linux (apt/yum/pacman) — sudo apt install ffmpeg or equivalent

After installing, verify both commands are available:

yt-dlp --version
ffmpeg -version
