This module integrates web push notification services into applications using the ABP framework. It facilitates real-time communication by enabling the sending and receiving of notifications directly through web browsers.

• Notification Management: Create, send, and manage web push notifications.
• Subscription Handling: Manage user subscriptions for receiving notifications.
• Real-Time Updates: Deliver notifications in real-time to engage users effectively.

To implement this module in your ABP framework application, @ TBD... Ensure to configure the necessary dependencies and integrate the service with your application's frontend and backend.

Step 1:

1. Install the WebPushNotificationService ABP Framework Module from Nuget into your project

2. Add DependsOn(typeof(WebPushxxxModule)) attribute to configure the module dependencies.

3. Add builder.ConfigureWebPush(); to the OnModelCreating() method in MyProjectMigrationsDbContext.cs.

4. Add EF Core migrations and update your database. The service will rely on three table to retrive and push notifications: WebPushContents, WebPushSubscriptions and WebPushNotifications

Step 2:

A pair of VAPID key is needed for the system (what is VAPID Key 🤔). There are multiple ways to generate them.

For Angular:

• Install the web-push package from NPM by running npm install web-push -g
• Generate the vapid keys by running web-push generate-vapid-keys [--json]. An example of a pair of VAPID Keys would be

Public Key:
BFwNomlUWWD2-wDR1cLhPQOxFskYDuUmseG_Pvi2DWI8eMMQuQufq27cQWa_tpO9sGK-AxRrKLdM2YLtdHTW1Dc

Private Key:
Ycpv7MDLJpB9512dZoQ6m2puX6tlnhMoKVtydY0Lz94

Step 3:

Set up the configuration by putting the pair of VAPID Keys into your application appsettings.json file. The structure of the key value pair would be as follow:

"WebPush": {
    "VapidKeys": {
      "PublicKey": "YOUR-PUBLIC-KEY",
      "PrivateKey": "YOUR-PUBLIC-KEY"
    },
    "Email": "YOUR-EMAIL"
  }

Create a ETO (event trasfer object) and push it to the event bus and it will handle the notification queue under the hood

var pushNotificationEto = 
        new CreateWebPushNotificationEto(CurrentTenant.Id, new List<Guid>{createMessageInput.ToUserId}, createMessageInput.Subject, 
            null, null, null, null, new DateTime?(), null);
await _distributedEventBus.PublishAsync(pushNotificationEto);
