API

import Zeroconf from 'react-native-zeroconf'
const zeroconf = new Zeroconf()
Methods
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.

publishService(type, protocol, domain, name, port) Publish a service

This adds a service for the current device to the discoverable services on the network.

domain should be the domain the service is sitting on, dot suffixed, for example 'local.' type should be both type and protocol, underscore prefixed, for example '_http._tcp' name should be unique to the device, often the device name port should be an integer

unpublishService(name) Unpublish a service

This removes a service from those discoverable on the network.

name should be the name used when publishing the service
