# Count the number of peers using the `scrape` feature of torrent trackers
|
|
|
|
Here's a full example with `browserify`.
|
|
|
|
```
|
|
npm install browserify parse-torrent bittorrent-tracker
|
|
```
|
|
|
|
`scrape.js`:
|
|
|
|
```js
|
|
var Tracker = require('bittorrent-tracker')
|
|
var magnet = require('magnet-uri')
|
|
|
|
// These values don't matter
|
|
var peerId = new Buffer('01234567890123456789')
|
|
var port = 6889
|
|
|
|
var magnetURI = "magnet:?xt=urn:btih:6a9759bffd5c0af65319979fb7832189f4f3c35d&dn=sintel.mp4&tr=udp%3A%2F%2Fexodus.desync.com%3A6969&tr=udp%3A%2F%2Ftracker.coppersurfer.tk%3A6969&tr=udp%3A%2F%2Ftracker.internetwarriors.net%3A1337&tr=udp%3A%2F%2Ftracker.leechers-paradise.org%3A6969&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80&tr=wss%3A%2F%2Ftracker.btorrent.xyz&tr=wss%3A%2F%2Ftracker.fastcast.nz&tr=wss%3A%2F%2Ftracker.openwebtorrent.com&tr=wss%3A%2F%2Ftracker.webtorrent.io&ws=https%3A%2F%2Fwebtorrent.io%2Ftorrents%2Fsintel-1024-surround.mp4"
|
|
|
|
var parsedTorrent = magnet(magnetURI)
|
|
var client = new Tracker(peerId, port, parsedTorrent)
|
|
|
|
client.scrape()
|
|
|
|
client.on('scrape', function (data) {
|
|
console.log(data)
|
|
})
|
|
```
|
|
|
|
Bundle up `scrape.js` and it's dependencies into a single file called `bundle.js`:
|
|
|
|
```bash
|
|
browserify scrape.js -o bundle.js
|
|
```
|
|
|
|
`index.html`:
|
|
|
|
```js
|
|
<script src="bundle.js"></script>
|
|
```
|
|
|
|
Open `index.html` in your browser.
