TinyTorrent

A tiny bittorrent client written in typescript for learning.

For details, check my blog post tinyTorrent: 从头写一个 Deno 的 BitTorrent 下载器.

NOTE: This is a leech client, it doesn't upload any data to peers!

Usage

$ deno run --allow-read --allow-net --allow-write src/main.ts <file.torrent> -- --debug # enable debug log

Create a local test torrent file

First, install and run bittorrent-tracker.

$ yarn add bittorrent-tracker 
$ ./node_modules/.bin/bittorrent-tracker --http

Tracker is running with the url: http://localhost:8000/announce.

Second, install Folx.

Select File -> Create Torrent File to create a torrent, add above url as the tracker url.

Now we have a test torrent file that can be downloaded by our client.
