bare-mdns-discovery

bare-mdns-discovery provides multicast DNS (mDNS) for Bare: low-level record queries and higher-level local service discovery. It's pure JavaScript, built on bare-dgram.

npm i bare-mdns-discovery

Usage

const { MDNS } = require('bare-mdns-discovery')

const mdns = new MDNS()
await mdns.ready()

mdns.on('records', (records, rinfo) => {
  for (const r of records) console.log(r.type, r.name, r.data)
})

mdns.query('_http._tcp.local')

API

MDNS

await mdns.ready()

Wait until the responder is bound and ready.

mdns.query(name[, type])

Send an mDNS query. Matching answers arrive on the records event ((records, rinfo)).
