Ionic Discover

Simple UDP based protocol for service discovery implemented in pure JS. It is not mDNS or bonjour, but it tries to accomplish the same thing.

Spec

It uses a JSON based textual format:

const message = {
  t: now,
  id: 'unique',
  name: this.name,
  host: os.hostname(),
  ip: iface.address,
  port: number1,
  commPort: number2
};

return 'ION_DP' + JSON.stringify(message);

key	description
`t`	unix timestamp in second
`id`	unique id for this session
`name`	name of the announced service
`host`	hostname of the machine announcing the service
`ip`	ipv4 address
`port`	tcp port of the announced service
`commPort`	optional websocket port of the communication server

Installation

npm install @ionic/discover

Usage

import { Publisher } from '@ionic/discover';

const namespace = 'your-service';
const serviceName = 'Ionic thing!';
const tcpPort = 8100;
const service = new Publisher(namespace, serviceName, tcpPort);

await service.start();
