Cordova Connectivity Monitor

Connectivity status monitoring for Cordova apps. Detects if there is WIFI/3G/EDGE/CDMA available.

Platform SDK supported

  • iOS
  • Android

How to use

To install this plugin, follow the Command-line Interface Guide. You can use one of the following command lines:

  • cordova plugin add cordova-connectivity-monitor
  • cordova plugin add https://github.com/appfeel/connectivity-monitor-cordova.git

To start monitoring connectivity, place the following code in your onDeviceReady callback. In order to attach an event listener, use document.addEventListener("deviceready", onDeviceReady, false).

    
    function onDeviceReady() {
      var myHostToObserve = "www.appfeel.com";
      
      document.removeEventListener('deviceready', onDeviceReady, false);
      
      document.addEventListener(connectivity.events.onReachabilityChanged, onReachabilityChanged, false)
      connectivity.observeRemoteHostName(myHostToObserve);
    }
    
    function onReachabilityChanged(e) {
      console.log(e.interface);
      swich(e.interface) {
        case connectivity.DISCONNECTED:
          console.log('DISCONNECTED');
          break;
        case WIFI:
          console.log('WIFI');
          break;
        case WIMAX:
          console.log('WIMAX');
          break;
        case ETHERNET:
          console.log('ETHERNET');
          break;
        case MOBILE:
          console.log('MOBILE');
          break;
        case UNDEFINED:
          console.log('UNDEFINED');
          break;
      }
      
      if (e.connected) {
        console.log("Is connected");
      } else {
        console.log("Is not connected");
      }
      
      swich(e.observer) {
        case HOST:
          console.log('HOST');
          break;
        case INTERNET:
          console.log('INTERNET');
          break;
        case LOCALWIFI:
          console.log('LOCALWIFI');
          break;
      }
    }

Javascript API

Note: All success callbacks are in the form 'function () {}', and all failure callbacks are in the form 'function (err) {}' where err is a String explaining the error reason.

connectivity.observeRemoteHostName(hostName, stopAllObservers, successCallback, failureCallback);

Observes changes of connectivity to a given hostname.

* {!Object}    hostName         (Optional) Name of the host to observe. Default www.google.com
* {Boolean}    stopAllObservers (Optional) Stop any existing observer. Default false
* {function()} successCallback  (Optional) Callback on success
* {function()} failureCallback  (Optional) Callback on fail

connectivity.observeRemoteIPV4(ipv4, stopAllObservers, successCallback, failureCallback);

Observes changes of connectivity to a given ip v4.

  • {!Object} ipv4 (Required) IP v4 to observe. Ex: 192.168.1.0
  • {Boolean} stopAllObservers (Optional) Stop any existing observer. Default false
  • {function()} successCallback (Optional) Callback on success
  • {function()} failureCallback (Optional) Callback on fail

connectivity.observeRemoteIPV6(ipv6, stopAllObservers, successCallback, failureCallback);

Observes changes of connectivity to a given ip v6.

  • {!Object} ipv6 (Required) IP v6 to observe. Ex: ::ffff:192.168.1.0
  • {Boolean} stopAllObservers (Optional) Stop any existing observer. Default false
  • {function()} successCallback (Optional) Callback on success
  • {function()} failureCallback (Optional) Callback on fail

connectivity.observeLocalWifi(stopAllObservers, successCallback, failureCallback);

Observes changes of connectivity to local wifi. (Android: Not yet implemented)

  • {Boolean} stopAllObservers (Optional) Stop any existing observer. Default false
  • {function()} successCallback (Optional) Callback on success
  • {function()} failureCallback (Optional) Callback on fail

connectivity.observeInternetConnection(stopAllObservers, successCallback, failureCallback);

Observes changes of connectivity to internet connection.

  • {Boolean} stopAllObservers (Optional) Stop any existing observer. Default false
  • {function()} successCallback (Optional) Callback on success
  • {function()} failureCallback (Optional) Callback on fail

connectivity.stopAllObservers(successCallback, failureCallback);

Stop any existing observer.

  • {function()} successCallback (Optional) Callback on success
  • {function()} failureCallback (Optional) Callback on fail

Events

document.addEventListener(connectivity.EVENTS.onReachabilityChanged, onReachabilityChanged, false)

Raised when there is a change in connectivity. It calls a function onReachabilityChanged(e) {}

  • {Object} e An object containing the following fields:
  • e.interface: The ingerface type that has changed connectivity status.
  • e.connected: True/False.
  • e.observer: The observer that raised the event.

Constants

connectivity.OBSERVER

Specifies the observer affected by the connectivity change:

  • HOST: specifies that the connectivity change affected host reachability.
  • INTERNET: specifies that the connectivity change affected internet reachability.
  • LOCALWIFI: specifies that the connectivity change affected local wifi reachability.

connectivity.INTERFACE

Specifies on which interface happened the connectivity change:

  • DISCONNECTED: no interface connected.
  • WIFI: connectivity change occured on wifi interface.
  • WIMAX: connectivity change occured on wifi interface.
  • ETHERNET: connectivity change occured on ethernet interface.
  • MOBILE: connectivity change occured on mobile (3G/GPRS/...) interface.
  • UNDEFINED: connectivity change occured on an undefined interface.
