};

    Functions

    function addEventListener

    addEventListener: (
    listener: Types.NetInfoChangeHandler
    ) => Types.NetInfoSubscription;
    • Subscribe to the global singleton's connection information. The callback is called with a parameter of type [NetInfoState](README.md#netinfostate) whenever the connection state changes. Your listener will be called with the latest information soon after you subscribe and then with any subsequent changes afterwards. You should not assume that the listener is called in the same way across devices or platforms.

      Parameter listener

      The listener which is called when the network state changes.

      Returns

      A function which can be called to unsubscribe.

    function configure

    configure: (configuration: Partial<Types.NetInfoConfiguration>) => void;
    • Configures the library with the given configuration. Note that calling this will stop all previously added listeners from being called again. It is best to call this right when your application is started to avoid issues. The configuration sets up a global singleton instance.

      Parameter configuration

      The new configuration to set.

    function fetch

    fetch: (requestedInterface?: string) => Promise<Types.NetInfoState>;
    • Returns a Promise that resolves to a NetInfoState object. This function operates on the global singleton instance configured using configure()

      Parameter requestedInterface

      interface from which to obtain the information

      Returns

      A Promise which contains the current connection state.

    function refresh

    refresh: () => Promise<Types.NetInfoState>;
    • Force-refreshes the internal state of the global singleton managed by this library.

      Returns

      A Promise which contains the updated connection state.

    function useNetInfo

    useNetInfo: (
    configuration?: Partial<Types.NetInfoConfiguration>
    ) => Types.NetInfoState;
    • A React Hook into this library's singleton which updates when the connection state changes.

      Parameter configuration

      Configure the isolated network checker managed by this hook

      Returns

      The connection state.

    function useNetInfoInstance

    useNetInfoInstance: (
    isPaused?: boolean,
    configuration?: Partial<Types.NetInfoConfiguration>
    ) => { netInfo: Types.NetInfoState; refresh: () => void };
    • A React Hook which manages an isolated instance of the network info manager. This is not a hook into a singleton shared state. NetInfo.configure, NetInfo.addEventListener, NetInfo.fetch, NetInfo.refresh are performed on a global singleton and have no affect on this hook.

      Parameter isPaused

      Pause the internal network checks.

      Parameter configuration

      Configure the isolated network checker managed by this hook

      Returns

      the netInfo state and a refresh function
