Webtorrent-beacon

Create a new torrent and receive a beacon when a new peer requests it

Webtorrent-beacon instantly sends a beacon when a new peer requests it. It does't care whether or not the new peer has actually connected to the torrent.

Some use-cases

• Instantly count peers interested in your torrent as they arrive (or leave [not as instantly])
• Instantly send a beacon to another instance (or multiple instances) of Webtorrent-beacon that a peer is interested in the same torrent. This may be useful for decentralizing WebRTC signaling between peers that connect to different tracker servers. Peerservers intends to use this library as the signaling method for peers connected to disparate tracker servers.

If you have another use-case, please share with an issue / PR!

let opts = {} // webtorrent options

let beacon = new Beacon(opts, filename, data, beacon => {

 if(beacon){
  console.log('Torrent has a new interested peer:', beacon) // true
 }

 if(!beacon){
  console.log('An interested peer has left')
 }

})

beacon.infoHash(infoHash => {
 console.log(infoHash)
})

beacon.magnet(magnet => {
 console.log(magnet)
})

API
