A cross-platform API that provides access to network information.

@react-native-community/netinfo allows you to get information about connection type and connection quality.

Installation

If you are installing this in an existing React Native app, make sure to install expo in your project. Then, follow the installation instructions provided in the library's README or documentation.

API

To import this library, use:

import NetInfo from '@react-native-community/netinfo';

If you want to grab information about the network connection just once, you can use:

NetInfo.fetch().then(state => {
  console.log('Connection type', state.type);
  console.log('Is connected?', state.isConnected);
});

Or, if you'd rather subscribe to updates about the network state (which then allows you to run code/perform actions anytime the network state changes) use:

const unsubscribe = NetInfo.addEventListener(state => {
  console.log('Connection type', state.type);
  console.log('Is connected?', state.isConnected);
});

// To unsubscribe to these update, just use:
unsubscribe();

Accessing the SSID

To access the ssid property (available under state.details.ssid), there are a few additional configuration steps:

• Request location permissions with Location.requestForegroundPermissionsAsync() or Location.requestBackgroundPermissionsAsync().

iOS only

• Add the com.apple.developer.networking.wifi-info entitlement to your app.json under ios.entitlements:

  app.json

  Copy

    "ios": {
      "entitlements": {
        "com.apple.developer.networking.wifi-info": true
      }
    }
  

• Check the Access Wi-Fi Information box in your app's App Identifier, which can be found here.

• Rebuild your app with eas build --platform ios or npx expo run:ios.
