Ionic Notification/Push message

Question

I need to send a JSON containing the category and the message all users who have my application installed, like this:

{category:"shoes", message:"New pair of shoes available"}

then I need to display a alert/notification only to users which checked a specific option which matches the category in the JSON.

I'm using Ionic, NodeJS and Express. How could I do that?

 Hello Shadow00, Then first of all you have to install FOUR Plugins for that. 1)cordova plugin add https://github.com/phonegap-build/PushPlugin // For notification 2)cordova plugin add cordova-plugin-device // For on Device Ready to call 3)cordova plugin add cordova-plugin-dialogs // For notification Dialog 4)cordova plugin add cordova-plugin-media // For Notification Sound 

and generate API key and SenderId throw developer console.and senderid past in bellow code. And e.regid pass to on server.

  <script type="text/javascript" src="PushNotification.js"></script>

        <script type="text/javascript">
            var pushNotification;

            function onDeviceReady() {
                $("#app-status-ul").append('<li>deviceready event received</li>');

                document.addEventListener("backbutton", function(e)
                {
                    $("#app-status-ul").append('<li>backbutton event received</li>');

                    if( $("#home").length > 0)
                    {
                        // call this to get a new token each time. don't call it to reuse existing token.
                        //pushNotification.unregister(successHandler, errorHandler);
                        e.preventDefault();
                        navigator.app.exitApp();
                    }
                    else
                    {
                        navigator.app.backHistory();
                    }
                }, false);

                try 
                { 
                    pushNotification = window.plugins.pushNotification;
              $("#app-status-ul").append('<li>registering ' + device.platform + '</li>');
                    if (device.platform == 'android' || device.platform == 'Android' ||
                            device.platform == 'amazon-fireos' ) {
            pushNotification.register(successHandler, errorHandler, {"senderID":"661780372179","ecb":"onNotification"});        // required!
