### Simple, robust, BitTorrent tracker (client & server) implementation
|
|
|
|
Node.js implementation of a [BitTorrent tracker](https://wiki.theory.org/BitTorrentSpecification#Tracker_HTTP.2FHTTPS_Protocol), client and server.
|
|
|
|
A **BitTorrent tracker** is an HTTP service which responds to GET requests from BitTorrent
|
|
clients. The requests include metrics from clients that help the tracker keep overall
|
|
statistics about the torrent. The response includes a peer list that helps the client
|
|
participate in the torrent.
|
|
|
|
Also see [BitTorrent DHT](https://github.com/feross/bittorrent-dht). This module is used
|
|
by [WebTorrent](http://webtorrent.io).
|
|
|
|
## install
|
|
|
|
```
|
|
npm install bittorrent-tracker
|
|
```
|
|
|
|
## usage
|
|
|
|
To connect to a tracker, just do this:
|
|
|
|
```js
|
|
var Client = require('bittorrent-tracker').Client
|
|
var parseTorrent = require('parse-torrent')
|
|
|
|
var torrent = fs.readFileSync(__dirname + '/torrents/bitlove-intro.torrent')
|
|
var parsedTorrent = parseTorrent(torrent) // { infoHash: 'xxx', length: xx, announce: ['xx', 'xx'] }
|
|
|
|
var peerId = new Buffer('01234567890123456789')
|
|
var port = 6881
|
|
|
|
var client = new Client(peerId, port, parsedTorrent)
|
|
|
|
// you must add an 'error' event handler!
|
|
client.on('error', function (err) {
|
|
console.log(err.message)
|
|
// a tracker was unavailable or sent bad data to the client. you can probably ignore it
|
|
})
|
|
|
|
// start getting peers from the tracker
|
|
client.start()
|
|
|
|
client.on('update', function (data) {
|
|
console.log('got a response from tracker: ' + data.announce)
|
|
console.log('number of seeders on this tracker: ' + data.complete)
|
|
console.log('number of leechers on this tracker: ' + data.incomplete)
|
|
})
|
|
|
|
client.once('peer', function (addr) {
|
|
console.log('found a peer: ' + addr) // 85.10.239.191:48623
|
|
})
|
|
|
|
// announce that download has completed (and you are now a seeder)
|
|
client.complete()
|
|
|
|
// force a tracker announce. will trigger more 'update' events and maybe more 'peer' events
|
|
client.update()
|
|
|
|
// stop getting peers from the tracker, gracefully leave the swarm
|
|
client.stop()
|
|
```
|
|
|
|
**TODO: Add a BitTorrent tracker server implementation to this package.**
|
|
|
|
```js
|
|
var Server = require('bittorrent-tracker').Server
|
|
|
|
// TODO
|
|
```
