--- title: @react-native-community/netinfo description: A cross-platform API that provides access to network information. sourceCodeUrl: https://github.com/react-native-community/react-native-netinfo packageName: @react-native-community/netinfo platforms: ["android", "ios", "tvos", "web"] inExpoGo: true --- `@react-native-community/netinfo` allows you to get information about connection type and connection quality. ## Installation ## API To import this library, use: ```js ``` If you want to grab information about the network connection just once, you can use: ```js 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: ```js 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()`](location.md#locationrequestforegroundpermissionsasync) or [`Location.requestBackgroundPermissionsAsync()`](location.md#locationrequestbackgroundpermissionsasync). ### iOS only - Add the `com.apple.developer.networking.wifi-info` entitlement to your **app.json** under `ios.entitlements`: ```json app.json "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](https://developer.apple.com/account/resources/identifiers/list). - Rebuild your app with [`eas build --platform ios`](/build/setup/#4-run-a-build) or [`npx expo run:ios`](/more/expo-cli/#compiling). ## Learn more
