mm-services-mdns

mm-services-mdns

directory service to store connection information for remote peers

works with MicroMinion platform

Initialization

var MicroMinionPlatform = require('mm-platform')
var MulticastDNS = require('mm-services-mdns')

var platform = new MicroMinionPlatform()

var mdns = new MulticastDNS({platform: platform})

Messaging API

Data structures

nodeInfo: Javascript object with node information

• boxId: base64 encoded public encryption key used by nacl
• signId: base64 encoded public signature key used by nacl
• connectionInfo: javascript dictionary with 1tp connection information

Published messages

self.transports.nodeInfo

Publishes connection information for remote node

var MicroMinionPlatform = require('mm-platform')
var MulticastDNS = require('mm-services-mdns')

var platform = new MicroMinionPlatform()

var mdns = new MulticastDNS({platform: platform})

platform.messaging.on('self.transports.nodeInfo', function(topic, sender, nodeInfo) {
  console.log(topic) // 'self.transports.nodeInfo'
  console.log(sender) // 'local'
  console.log(nodeInfo) // {boxId: <boxId>, signId: <signId>, connectionInfo: <1tp connectionInfo>}
})

self.transports.nodeInfoBootstrap

Publishes bootstrap information for remote nodes (used by DHT)

var MicroMinionPlatform = require('mm-platform')
var MulticastDNS = require('mm-services-mdns')

var platform = new MicroMinionPlatform()

var mdns = new MulticastDNS({platform: platform})

platform.messaging.on('self.transports.nodeInfo', function(topic, sender, nodeInfo) {
  console.log(topic) // 'self.transports.nodeInfo'
  console.log(sender) // 'local'
  console.log(nodeInfo) // {boxId: <boxId>, signId: <signId>, connectionInfo: <1tp connectionInfo>}
})

Subscribed messages

self.transports.myNodeInfo

Uses our own node information to broadcast on local network through mdns

You'll never need to send this message since this is triggered from the platform object

var MicroMinionPlatform = require('mm-platform')
var MulticastDNS = require('mm-services-mdns')

var platform = new MicroMinionPlatform()

var mdns = new MulticastDNS({platform: platform})

var nodeInfo = {
  boxId: platform.directory.identity.getBoxId()
  signId: platform.directory.identity.getSignId()
  connectionInfo: platform.directory._connectionInfo
}

platform.messaging.send('transports.myNodeInfo', 'local', nodeInfo)

self.transports.requestBootstrapNodeInfo

Request message that triggers 'nodeInfoBootstrap' responses

Needed if you want to implement your own directory service or want to discover local nodes

var MicroMinionPlatform = require('mm-platform')
var MulticastDNS = require('mm-services-mdns')

var platform = new MicroMinionPlatform()

var mdns = new MulticastDNS({platform: platform})

platform.messaging.send('transports.requestBootstrapNodeInfo', 'local', {})
