Kumara-discover is a streaming Signal K mDNS discovery library.

API

discover ()

Returns Flyd stream of immutable Maps, identifying sK advertisers by URL.

Example

import discover from 'kumara-discover';
 
const servers = discover();
 
servers.map(
  state => state.toJS() // Convert immutable to plain JS object
).map(
  state => JSON.stringify(state, null, 2)
).map(
  state => console.log('\n###', state)
);

This would return a bunch of messages such as the following:
