Installation

yarn add react-native-zeroconf
cd ios && pod install

1.0 release candidate: one C++ native module on every platform, for React Native 0.82 and later (New Architecture, Expo SDK 55 and later). Try it with npm install react-native-zeroconf@next, see what changes from 0.17. The documentation covers 0.17, which stays the default and keeps getting bug fixes.

On iOS, declare the service types you use in NSBonjourServices, see Permissions and Setup. Expo works with development builds, see Installation with Expo.

Usage

import { useZeroconf } from 'react-native-zeroconf'

function Printers() {
  const { services } = useZeroconf({ type: 'ipp' })

  return services.map(service => (
    <Text key={service.name}>
      {service.name} {service.ipv4[0]}:{service.port}
    </Text>
  ))
}

Without React:

import Zeroconf from 'react-native-zeroconf'

const zeroconf = new Zeroconf()
zeroconf.on('resolved', service => console.log(service.name, service.host, service.port))
zeroconf.scan({ type: 'http' })
