Visual LANSA is integrated with push notifications to keep you informed about important updates from apps. The push notifications lifecycle is the following:
- Request Permission to send push notifications.
- A user subscribes to receive push notifications from a web application resulting in a subscription object.
- The web application passes the subscription object to the application server to store it in a database.
- An event is triggered on the application server to send a notification. The subscription objects are fetched from the database.
- A push notification request is sent to the user agent.
- The user agent processes the request.
- The end user receives the notification.
LANSA simplifies this entire process by making it easy to get updates:
- The Visual LANSA Web Push Manager allows users to easily subscribe to receive notifications and results in the subscription object.
- The subscription object is passed back to the server module and stored in a database table.
- LANSA defines an event for sending a notification. For example, the system will be undergoing maintenance at a given time and date, there is a sale on a product or a set of tasks have been completed.
- The subscription object can then be fetched from the database table on demand to construct a custom notification for the end user.
- The notification is sent from your LANSA application.
The Visual LANSA Push Notification feature simplifies the enhancement of your Progressive Web Applications (PWA). It removes the complexities associated with integrating multiple systems, languages, and technologies, along with the need for custom encryption and managing data across different platforms.
To start using this feature you need to enable the Visual LANSA PWA web application and an EC256 private key.
