Basic Zeroconf implementation for React-native

Get running services advertizing themselves using Zeroconf implementations like Avahi, Bonjour or NSD.


npm i -S react-native-zeroconf
react-native install react-native-zeroconf
react-native link react-native-zeroconf

You can look at the wiki if you prefer a manual install.

TXT records will be available on iOS and Android >= 7.


import Zeroconf from 'react-native-zeroconf'
const zeroconf = new Zeroconf()
scan(type = 'http', protocol = 'tcp', domain = 'local.') Start the zeroconf scan

This will initialize the scan from the Zeroconf instance. Will stop another scan if any is running.

stop() Stop the scan

If any scan is running, stop it. Otherwise do nothing.

getServices() Returns resolved services

Will return all names of services that have been resolved.

removeDeviceListeners() Remove listeners

Allow you to clean the listeners, avoiding potential memory leaks (#33).

addDeviceListeners() Add listeners

If you cleaned the listeners and need to get them back on.

zeroconf.on('start', () => console.log('The scan has started.'))

stop Triggered on scan stop
found Triggered when a service is found
