NativeScript Firebase Cloud Messaging

This is the plugin that adds FCM support to a NativeScript app.

WORK IN PROGRESS... Stay tuned. ANDROID IMPLEMENTATION IS COMPLETE.

API Example

var FCM = require('nativescript-fcm');

// Register token refresh listener
FCM.setTokenRefreshListener(function(e) {
  sendTokenToBackend(e.token);
});

// Register message listener
FCM.setMessageListener(function(message, data) {
  // message.messageId
  // message.messageType
  // message.sentTime
  // message.ttl
  // message.from
  // message.to
  // message.body
  // message.title
  // message.icon
  // message.sound
  // message.tag
  // message.color

  // #data contains your custom key / values
});

// Start by requesting the token and sending it to the server.
// When token changes, you will receive EVENT_TOKEN_REFRESH event.
var token = FCM.getToken();
if (token) {
  sendTokenToBackend(token);

  // (Optionally) subscribe to a topic
  FCM.subscribeToTopic("news");
} else {
  // ... Unable to get token ...
}

Handling app launches

When the user taps the notification, your app is launched with some extra data. Here's how you can easily extract it in your app.js:

var Application = require("application");
var FCM         = require("nativescript-fcm");

// On app launch, but before we do anything else, we check how
// exactly this app was started.
Application.on(Application.launchEvent, function(args) {
  var notificationData = FCM.launchNotificationData(args);

  if (notificationData) {
    console.log("Launched from notification:");
    console.log(JSON.stringify(notificationData));

    // Normal notification:
    // {"custom_key":"value","from":"1081060181241","collapse_key":"com.myapp.test"}
    //
    // Topic notification:
    // {"from":"/topics/news","collapse_key":"com.myapp.test"}

  } else {
    console.log("Normal launch");
  }
});

Application.start({ moduleName: "main-page" });

Android

Prerequisites

Google Play services 30
Google Repository 28
google-services.json generated in the Firebase Console (https://console.firebase.google.com) for your project.

Installation

In app/App_Resources/Android/app.gradle add your app ID (you can find it in package.json):
```
android {
  defaultConfig {
    ...
    applicationId "com.myapp.id"
    ...
  }
}
```
In platforms/android/build.gradle...
- Near the top add Google Services to the dependencies section like this (gradle classpath should already be there):
```
dependencies {
  classpath "com.android.tools.build:gradle:1.5.0"
  classpath "com.google.gms:google-services:3.0.0"
}
```
- At the very bottom add Google Services plugin:
```
  apply plugin: "com.google.gms.google-services"
```
Put your google-services.json into platforms/android/ folder.

Troubleshooting

TNS build says it can't find firebase-messaging or firebase-core.

You don't have correct Play services / repository SDK installed. Launch Android SDK Manager and look for them in the Extras section.

TNS build says: "File google-services.json is missing. The Google Services Plugin cannot function without it."

Put your google-services.json into platforms/android. You may want a custom script that does that before the build, as this dir can be removed.
