Connectivity

The connectivity module provides a common abstraction of the functionality responsible for receiving information about the connection type and availability of the network.

Usage

const connectivityModule = require("tns-core-modules/connectivity"); exports.onNavigatedTo = function(args) { const page = args.object; let connectionTypeString; const type = connectivityModule.getConnectionType(); switch (type) { case connectivityModule.connectionType.none: console.log("No connection"); connectionTypeString = "No Internet connectivity!"; break; case connectivityModule.connectionType.wifi: console.log("WiFi connection"); connectionTypeString = "WiFI connectivity!"; break; case connectivityModule.connectionType.mobile: console.log("Mobile connection"); connectionTypeString = "Mobile connectivity!"; break; case connectivityModule.connectionType.ethernet: console.log("Ethernet connection"); connectionTypeString = "Ethernet connectivity!"; break; case connectivityModule.connectionType.bluetooth: console.log("Bluetooth connection"); connectionTypeString = "Bluetooth connectivity!"; break; default: break; } connectivityModule.startMonitoring((newConnectionType) => { switch (newConnectionType) { case connectivityModule.connectionType.none: console.log("Connection type changed to none."); break; case connectivityModule.connectionType.wifi: console.log("Connection type changed to WiFi."); break; case connectivityModule.connectionType.mobile: console.log("Connection type changed to mobile."); break; case connectivityModule.connectionType.ethernet: console.log("Connection type changed to ethernet."); break; case connectivityModule.connectionType.bluetooth: console.log("Connection type changed to bluetooth."); break; default: break; } }); // Stoping the connection monitoring connectivityModule.stopMonitoring(); page.bindingContext = { connectionType: connectionTypeString }; };
