    Basic Zeroconf implementation for React-native

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


    yarn add react-native-zeroconf
    # for react-native < 0.60 only (all platforms):
    react-native link
    # for ios (when using CocoaPods): 
    (cd ios && pod install)

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

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

    For Android please ensure your manifest is requesting all necessary permissions.

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_MULTICAST_STATE" />


    Take a look at the example folder. Install the dependencies, run node server.js and launch the project.


    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.

    publishService(type, protocol, domain, name, port, txt) 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 txt should be a hash, for example {"foo": "bar"}

    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

    zeroconf.on('start', () => console.log('The scan has started.'))
    start Triggered on scan start
    stop Triggered on scan stop
    found Triggered when a service is found

    Broadcast a service name as soon as it is found.

    resolved Triggered when a service is resolved

    Broadcast a service object once it is fully resolved

      "host": "XeroxPrinter.local.",
      "addresses": [
      "name": "Xerox Printer",
      "fullName": "XeroxPrinter.local._http._tcp.",
      "port": 8080
    remove Triggered when a service is removed

    Broadcast a service name removed from the network.

    update Triggered either when a service is found or removed
    error Triggered when an error occurs
