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:

``ts
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

`ts
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();
