webtorrentify-link

Generate a WebTorrent-compatible .torrent from a URL

What it does

This module will take a download URL and convert it into a .torrent file. Warning: it downloads the URL in order to do this. It's basically a thin wrapper around create-torrent that makes sure the .torrent files satisfy certain properties.

Features

• Deterministic. Assuming the file on the server hasn't changed, identical input will result in identical output.
• WebSeeds. It lists the source URL as a WebSeed in order to bootstrap the torrent, so it always has at least one seed.
• WebTorrent trackers. Client side JavaScript cannot make UDP requests, so it cannot use traditional UDP trackers. The .torrent files generated use the default tracker list from create-torrent, which includes both UDP and WebSocket trackers.
