Number of Seeders/Leechers

[GuacheSuede]

Hello Webtorrent,

how does one get total number of peers(seeders, leechers) without downloading ?

Cheers

You can do this by "scraping" a tracker, see https://wiki.vuze.com/w/Scrape.

You can use https://github.com/feross/bittorrent-tracker as a client (see https://github.com/feross/bittorrent-tracker#client).

Hi Gillesdemy,

There's a project that harvests IP addresses of peers https://github.com/Stefan-Code/peer-harvest that uses PEX and DHT.

DHT works very differently from regular trackers, there's a great presentation on crawling the DHT: https://www.defcon.org/images/defcon-18/dc-18-presentations/Wolchok/DEFCON-18-Wolchok-Crawling-Bittorrent-DHTS.pdf

For PEX, you can listen for new peers and keep track of a unique map of connected peers to the swarm.
See https://github.com/Stefan-Code/peer-harvest/blob/master/peer-harvest.js#L305-L324
