capacitor-fcm npm version

Capacitor plugin to enable features from Firebase Cloud Messaging

Notice

This plugin is intended to be used combined with Capacitor API for Push Notifications. Capacitor only provides APN token whereas this plugin offers the possibility to work with FCM tokens and more.

API

method info platform
subscribeTo subscribe to fcm topic ios/android
unsubscribeFrom unsubscribe from fcm topic ios/android
getToken get fcm token to eventually use from a server ios/android
deleteInstance remove local fcm instance completely ios/android

Usage

import { Plugins } from "@capacitor/core";
const { PushNotifications } = Plugins;

//
// with type support
import { FCM } from "capacitor-fcm";
const fcm = new FCM();

//
// alternatively - without types
const { FCMPlugin } = Plugins;

//
// external required step
// register for push
PushNotifications.register()
  .then(() => {
    //
    // Subscribe to a specific topic
    // you can use `FCMPlugin` or just `fcm`
    fcm
      .subscribeTo({ topic: "test" })
      .then(r => alert(`subscribed to topic`))
      .catch(err => console.log(err));
  })
  .catch(err => alert(JSON.stringify(err)));

//
// Unsubscribe from a specific topic
fcm
  .unsubscribeFrom({ topic: "test" })
  .then(() => alert(`unsubscribed from topic`))
  .catch(err => console.log(err));

//
// Get FCM token instead the APN one returned by Capacitor
fcm
  .getToken()
  .then(r => alert(`Token ${r.token}`))
  .catch(err => console.log(err));

//
// Remove FCM instance
fcm
  .deleteInstance()
  .then(() => alert(`Token deleted`))
  .catch(err => console.log(err));

Add Google config files

Navigate to the project settings page for your app on Firebase.

iOS

Download the GoogleService-Info.plist file. In Xcode right-click on the yellow folder named "App" and select the Add files to "App".

Tip: if you drag and drop your file to this location, Xcode may not be able to find it.

Android

Download the google-services.json file and copy it to android/app/ directory of your capacitor project.

Certificate

iOS setup

  • sudo gem install cocoapods (once a time)
  • ionic start my-cap-app --capacitor
  • cd my-cap-app
  • mkdir www && touch www/index.html
  • npx cap add ios
  • npm install --save capacitor-fcm
  • npx cap sync ios (always do sync after a plugin install)
  • npx cap open ios
  • sign your app at xcode (general tab)
  • enable remote notification capabilities
  • add GoogleService-Info.plist to the app folder in xcode
// (optional) turn off `swizzling` in the `info.plist`
<key>FirebaseAppDelegateProxyEnabled</key>
<false/>

Tip: every time you change a native code you may need to clean up the cache (Product > Clean build folder) and then run the app again.

Android setup

  • ionic start my-cap-app --capacitor
  • cd my-cap-app
  • mkdir www && touch www/index.html
  • npx cap add android
  • npm install --save capacitor-fcm
  • npx cap sync android (always do sync after a plugin install)
  • npx cap open android
  • add google-services.json to your android/app folder
  • [extra step] in android case we need to tell Capacitor to initialise the plugin:

on your MainActivity.java file add import io.stewan.capacitor.fcm.FCMPlugin; and then inside the init callback add(FCMPlugin.class);

Now you should be set to go. Try to run your client using ionic cap run android --livereload.

Tip: every time you change a native code you may need to clean up the cache (Build > Clean Project | Build > Rebuild Project) and then run the app again.
