hyperlog-webtorrent-seed

seed webtorrent magnet links from a hyperlog

example

Mirror content from a swarmlog:

var webtorrent = require('webtorrent')
var level = require('level')
var swarmlog = require('swarmlog')
var fstore = require('fs-chunk-store')

var log = swarmlog({
  id: process.argv[2],
  db: level('/tmp/webtorrent-mirror.log'),
  sodium: require('chloride'),
  valueEncoding: 'json',
  hubs: [ 'https://signalhub.mafintosh.com' ]
})

var hseed = require('hyperlog-seed')
var seeder = hseed({
  db: level('/tmp/webtorrent-mirror.seed'),
  log: log,
  map: function (row) {
    if (row.link) return { type: 'put', link: row.link }
    if (row.unlink) return { type: 'del', link: row.unlink }
  }
})

var wseed = require('hyperlog-webtorrent-seed')
wseed({
  db: level('/tmp/webtorrent-mirror.wseed'),
  store: function (n, opts) {
    return fstore(n, {
      path: '/tmp/webtorrent-mirror.store',
      length: opts.length
    })
  },
  seeder: seeder,
  client: webtorrent()
})

Seed content from stdin and publish the magnet links to a swarmlog:

var webtorrent = require('webtorrent')
var parseTorrent = require('parse-torrent')
var level = require('level')
var swarmlog = require('swarmlog')

var log = swarmlog({
  keys: require('./keys.json'),
  db: level('/tmp/webtorrent-publish.db'),
  sodium: require('chloride'),
  valueEncoding: 'json',
  hubs: [ 'https://signalhub.mafintosh.com' ]
})

var client = webtorrent()
client.seed([process.stdin], { name: 'test.txt' }, function (torrent) {
  log.append({ link: torrent.magnetURI })
  console.log(torrent.magnetURI)
})

Generate a keypair for the swarmlog and set up a mirror to follow the public key:

$ node -pe "JSON.stringify(require('ssb-keys').generate())" > keys.json
$ json public < keys.json
T+EccaMYIIsfqNu0Mz549yNhmRC3HCrWr8oghnWHoRw=.ed25519
$ electron-spawn mirror.js T+EccaMYIIsfqNu0Mz549yNhmRC3HCrWr8oghnWHoRw=.ed25519

Publish content and download the content from the mirror with webtorrent:

$ echo WOW | electron-spawn publish.js

api

var wseed = require('hyperlog-webtorrent-seed')

var w = wseed(opts)

Seed to webtorrent given:

• opts.client - a webtorrent instance
• opts.seeder - a hyperlog-seed instance
• opts.db - a levelup instance
• opts.store(chunkLength, opts) - function that returns an abstract-chunk-store instance given a chunkLength and an opts.length of the entire file

In the browser, use idb-chunk-store as opts.store and level-browserify for the opts.db.

w.on('error', function (err) {})

Internal errors are available in the 'error' event.
