react-native-connectivity-tracker

Why?

Because we can no longer trust that react-native connectivity changes are valid, so we have to double check before we trust the result. Here's the RN issue

Usage:

import ConnectivityTracker from 'react-native-connectivity-tracker';

const onConnectivityChange = (isConnected, timestamp, connectionInfo) => {
    console.log(`isConnected: ${isConnected}, when: ${timestamp} more info: ${JSON.stringify(connectionInfo)}`)
    // connectionInfo is only available if attachConnectionInfo is set to true
}

ConnectivityTracker.init({
    onConnectivityChange,
    attachConnectionInfo: false,
    onError: msg => console.log(msg),
    // verifyServersAreUp: store.dispatch(checkOurServersAreUp()),
});

Params:

Key	Type	Default	Definition
onConnectivityChange	function(bool, Date, Object)	-	This is the main callback you should care about. It get's dispatched whenever there's a connectivity change.
attachConnectionInfo	boolean	false	Attaches more details about the connection on the onConnectivityChange callback (3rd param)
alsoVerifyOnlineStatuses	boolean	false	By default we only verify the connectivity whenever we receive an offline status. By turning this on we'll also verify online statuses too.
dispatchOldEventsToo	boolean	false	By default we only dispatch the latest event we received from NetInfo. By turning this on we'll dispatch EVERYTHING. Caution, the order of events is not guaranteed if this is set to true.
onError	function	-	Pass a function here if you want to log errors.
verifyServersAreUp	Promise or function	-	This overrides the default verification method. Feel free to disregard this, unless want to use your own verification method, instead of relying to google responces.
