hypercore-multicast-swarm
Multicast hypercore data over a multicast UDP socket
npm install hypercore-multicast-swarm
Still does all the data verification that hypercore normally does etc, it's just multicast!
Usage
const mswarm = require('hypercore-multicast-swarm')
// this will make the hypercore listen for multicast data on the network.
// when it receives a message it doesn't have it will verify it and store it.
const swarm = mswarm(someHypercoreFeed)
someHypercoreFeed.on('download', function (seq, data) {
console.log('we recevied ' + seq + ' over multicast')
})
// to multicast a hypercore entry
swarm.multicast(42) // multicasts entry 42API
swarm = mswarm(feed, [options])
Make a hypercore feed join the multicast swarm. Options include:
{
mtu: 900,
port: 5007,
address: '224.1.1.1' // the multicast address to use
}No hypercore messages are multicast until you call the multicast api below
swarm.multicast(seq, [callback])
Multicast the entry stored at seq in the feed.
The callback is called when the underlying udp socket has been flushed.
