Sparc.Notifications.Azure

The Sparc.Notifications.Azure library enables integration between Sparc projects and Azure Notification Hubs, with fallbacks for Web Push.

Getting Started

Step 1: Install the Package

  1. Install the Sparc.Notifications.Azure NuGet package to your Sparc Features project:

    > dotnet add package Sparc.Notifications.Azure

  2. Add the following line of code to Startup.cs to register the library's services:

    services.AddAzurePushNotifications(Configuration.GetSection("Notifications"));

Step 2: Set Up Your Platforms

Android
  1. Create a project in Firebase: https://firebase.google.com/docs/projects/learn-more#project-id
  2. Add an Android App to your Firebase project and download the google-services.json file, then add it to your Sparc MAUI platform project.
  3. In Firebase Console, switch to the Cloud Messaging tab and copy the Server Key.
  4. Add the following entries to your Sparc MAUI .csproj file (reference): 
    <ItemGroup>
    <GoogleServicesJson Include="google-services.json" />
</ItemGroup>
  5. Add the following entries to your Sparc MAUI AndroidManifest.xml file: 
    <uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.GET_ACCOUNTS"/>
Web

  1. Add a Web Push Key Pair in the Cloud Messaging section of your Firebase project.

  2. Add the necessary JavaScript to your Sparc Web index.html file (reference). Example:

    <body>

  <script type="module">
    import { initializeApp } from 'https://www.gstatic.com/firebasejs/9.6.10/firebase-app.js'

    // Add Firebase products that you want to use
    import { getMessaging, getToken, onMessage } from 'https://www.gstatic.com/firebasejs/9.6.10/firebase-messaging.js'

    // TODO: Replace the following with your app's Firebase project configuration
    // See: https://firebase.google.com/docs/web/learn-more#config-object
    const firebaseConfig = {
      // ...
    };

    // Initialize Firebase
    const app = initializeApp(firebaseConfig);


    // Initialize Firebase Cloud Messaging and get a reference to the service
    const messaging = getMessaging(app);

    // Get registration token. Initially this makes a network call, once retrieved
    // subsequent calls to getToken will return from cache.
    const messaging = getMessaging();
    getToken(messaging, { vapidKey: '<YOUR_PUBLIC_VAPID_KEY_HERE>' }).then((currentToken) => {
      if (currentToken) {
        // Send the token to your server and update the UI if necessary
        // ...
      } else {
        // Show permission request UI
        console.log('No registration token available. Request permission to generate one.');
        // ...
      }
    }).catch((err) => {
      console.log('An error occurred while retrieving token. ', err);
      // ...
    });

  </script>
</body>

  3. Add an empty firebase-messaging-sw.js file to the root of your domain (ie. the wwwroot folder of your Sparc Web project).

  4. Set up your app to handle messages that come in when your app is in the foreground (background messages are handled automatically by the browser):

    // Handle incoming messages. Called when:
// - a message is received while the app has focus
// - the user clicks on an app notification created by a service worker
//   `messaging.onBackgroundMessage` handler.

onMessage(messaging, (payload) => {
  console.log('Message received. ', payload);
  // ...
});

Step 3: Set Up Azure Notification Hubs

  1. Create a Notification Hub in Azure and copy the DefaultFullSharedAccessSignature connection string.

  2. In the Google/FCM settings, copy the API key from step 3 in the Android section above.

  3. In the Apple settings, copy the API key from step 3 in the Apple section above.

  4. Add the following section to your Sparc Web / Sparc MAUI projects' appsettings.json file:

    {
   "Notifications": {
      "ConnectionString": "[The DefaultFullSharedAccessSignature from Step 1 above]",
      "HubName": "[The name of your Azure Hub]"
   }
}

Step 4: Register the User's Devices in the Backend

  1. Inject AzureNotificationService into an appropriate Feature (i.e. a feature that registers users and/or devices).

    public RegisterDevice(AzureNotificationService notifications) => Notifications = notifications;

  2. Call the RegisterAsync method on the AzureNotificationService to register the device with Azure Notification Hubs, passing in the token received from the client.

    // userId is your app's identifier for the user
// device is an injectable object of type Device that automatically pulls device and push token info from each Sparc platform 

await notifications.RegisterAsync(userId, device);

Step 5: Send Messages

  1. Inject AzureNotificationService into the Feature.

    public NotifyUser(AzureNotificationService notifications) => Notifications = notifications;

  2. Create your message using the Message class from Sparc.Notifications.Azure. This class represents a generic message that will be automatically translated into Android, iOS, and Web push formats for Firebase and APS.

  3. Send your message using the SendAsync function.

    Message message = new("Time to wake up!", "Wake up, sleepyhead. It's time to face the new day!");

// Send to a specific user
await notifications.SendAsync(userId, message);

// Send to a specific device
await notifications.SendAsync(userId, deviceId, message);

// Send to a specific group of users
await notifications.SendAsync(message, "user-group-1");
