youtube-dl-playlist is a Node.js program that uses youtube-dl or cURL to download an entire playlist loaded in from a JSON file.
The program automatically will download all tracks with the best audio available, then convert them into mp3 files using FFmpeg and add ID3v2 frames to the file.

Only one path must be given the program.
The given file must be a JSON array where each item must match the following schema:

{
	"title": string,
	"artist": string,
	"featured_artists"?: string[],
	"album"?: string,
	"nr"?: number,
	"year"?: number,
	"comments"?: string | string[],
	"url"?: string,
	"fallback_urls"?: string[],
	"file"?: string,
	"fallback_files"?: string[],
	"other"?: any
}

URLs in "url" and "fallback_urls" will be download using youtube-dl and all URLs in "file" and "fallback_files" will be downloaded using cURL.

The following options can be specified:

• --download
  Download the playlist
• --high-effort
  Downloads the playlist faster, but uses more system resources.
  Implies the --download option
• --only-show-errors
  Only log tracks that failed to download.
  Implies the --download option
• --compact
  Overwrite the given file with compact JSON. Saves some space
• --pretty=(tab|<number_of_spaces>)
  Overwrite the given file with formatted JSON, either with tabs as indentation or with the number of spaces specified. Good for editing and viewing
• --sort
  Also sort the playlist before overwriting.
  Requires either the --compact or the --pretty option

It's not allowed to give both the --compact and the --pretty options at once.
The --download and one of the overwrite options (--compact and --pretty) are both allowed to be given at once.

youtube-dl, cURL and FFmpeg needs be installed on the system and their binaries must be available on your PATH.

Install using npm:

npm i -g @mfederczuk/youtube-dl-playlist
