Check Internet Connection is Available in Ionic Application

The following Content will show you how to make use of social media sharing in your Android and Windows and iOS mobile application using Ionic Framework.
To implement this , we’ll be using the plugin cordova-plugin-network-information.
1.Create the project
ionic start Test blank
cd Test
ionic platform add android
2.Add Plugin
This plugin provides an implementation of an old version of the Network Information API. It provides information about the device's cellular and wifi connection, and whether the device has an internet connection.
This plugin not supported in browser for testing build in device.
   cordova plugin add cordova-plugin-network-information
Until Cordova 2.3.0, the Connection object was accessed via navigator.network.connection, after which it was changed to navigator.connection to match the W3C specification. It's still available at its original location, but is deprecated and will eventually be removed.
3.Implementation
In your index.html nothing to change for testing purpose you just need to add following code in your app.js to showing network connection problem.
app.js
// Ionic Starter App
// angular.module is a global place for creating, registering and retrieving Angular modules
// 'starter' is the name of this angular module example (also set in a <body> attribute in index.html)
// the 2nd parameter is an array of 'requires'
angular.module('starter', ['ionic'])
.run(function($ionicPlatform, $ionicPopup) {
 $ionicPlatform.ready(function() {
   // Check for network connection
   if(window.Connection) {
     if(navigator.connection.type == Connection.NONE) {
       $ionicPopup.confirm({
         title: 'Network Problem',
         content: 'Sorry, Please Check Your Network Connection.'
       })
       .then(function(result) {
         if(!result) {
           navigator.app.exitApp();
         }
       });
     }
   }
 });
})
4.Build or Run It

ionic build android or

         ionic run android
NOTE:
Here , the connection object, exposed via navigator.connection, provides information about the device's cellular and wifi connection.
Available more constants with it as follows ,
  • Connection.UNKNOWN
  • Connection.ETHERNET
  • Connection.WIFI
  • Connection.CELL_2G
  • Connection.CELL_3G
  • Connection.CELL_4G
  • Connection.CELL
  • Connection.NONE

Simple example for connection.type


function checkConnection() {
    var networkState = navigator.connection.type;

    var states = {};
    states[Connection.UNKNOWN]  = 'Unknown connection';
    states[Connection.ETHERNET] = 'Ethernet connection';
    states[Connection.WIFI]     = 'WiFi connection';
    states[Connection.CELL_2G]  = 'Cell 2G connection';
    states[Connection.CELL_3G]  = 'Cell 3G connection';
    states[Connection.CELL_4G]  = 'Cell 4G connection';
    states[Connection.CELL]     = 'Cell generic connection';
    states[Connection.NONE]     = 'No network connection';

    alert('Connection type: ' + states[networkState]);
}

    Dropped internet connection is really a big problem. A reliable connection is always needed. The internet service provider Reno should be careful about this and give support to clients.

What exactly means MVW design pattern ?

What is a MVW framework? The abbreviation stands for 'Model - View - Whatever'.  Well there are many different JavaScript frameworks available , all invented for the same purpose. They all try to separate the presentation logic from the business logic where JavaScript holds the model and logic, and html the presentation layer. Quick overview : You can change the model without changing the view and vice-versa Unit testing is easy These are the core benefits of using such a framework. By separating presentation and business logic changes to the code are easier to implement and take less time. Another benefit is that code can be reused from a controller thus saving more time. Angularjs makes the code also shorter in comparison to other frameworks, which improves code stability. Less code means minor potential for bugs. For several years +AngularJS was closer to MVC (or rather one of its client-side variants), but over time and thanks to many refactorings...

Steps To Create Cordova Plugin

Introduction A plugin is a package of injected code that allows the Cordova webview within which the app renders to communicate with the native platform on which it runs. Plugins comprise a single JavaScript interface along with corresponding native code libraries for each supported platform. Due to following reason, we will go for plugin development To get the native capabilities of the device in the cordova based app Build the common functionality across the number of Cordova application(Reusability) Prerequisites For the creation of plugin you need to install plugman . npm install -g plugman Plugin Structure Decide Plugin ID & Name The plugin ID should be unique Plugin name should follow the convention “cordova.plugin.[your.plugin.name]” Create the structure Use the following command to create the plugin with plugin ID “cordova.plugin.test” and name “Test”. plugman create --name Test --...
