How to Implement PWA Push Notifications With OneSignal

Progressive Web Apps (PWAs) are becoming increasingly popular for their ability to deliver a native app-like experience directly through a web browser. One of the standout features of PWAs is the ability to send push notifications, enhancing user engagement and retention. In this article, we'll explore how to implement PWA push notifications using OneSignal, enabling you to effectively communicate with your users.

Step 1: Create a OneSignal Account

The first step in implementing push notifications for your PWA is to create an account on OneSignal. Visit the OneSignal website and sign up for a free account. Once you’ve registered, you’ll be directed to the dashboard where you can create a new app.

Step 2: Set Up a New App

To set up your PWA, click on "Add a New App" from the dashboard. After naming your app, select the platform as "Web" and then choose "PWA." You will then be prompted to configure some essential settings.

Step 3: Configure Web Push Settings

In the Web Push settings, you will need to enter your site’s URL and specify whether you want to allow users to opt into notifications. OneSignal will also require you to provide a default icon and a notification title. Make sure to customize these to match your brand for a consistent user experience.

Step 4: Generate Your OneSignal SDK Key

After configuring your settings, OneSignal will provide you with an SDK key and other necessary information. This SDK key will be crucial for integrating OneSignal with your PWA. Make sure to note it down as you will use it in the next steps.

Step 5: Integrate OneSignal in Your PWA

To include OneSignal in your PWA, you will need to add the OneSignal SDK to your application. Place the following script in the <head> section of your HTML:


<script src="https://cdn.onesignal.com/sdks/OneSignalSDK.js" async></script>
<script>
    var OneSignal = OneSignal || [];
    OneSignal.push(["init", {
        appId: "YOUR_ONESIGNAL_APP_ID",
        safari_web_id: "YOUR_SAFARI_WEB_ID", // Only required for Safari
        notifyButton: {
            enable: true, // Set to false to hide the button
        },
    }]);
</script>

Make sure to replace YOUR_ONESIGNAL_APP_ID and YOUR_SAFARI_WEB_ID with the relevant keys obtained from OneSignal during setup.

Step 6: Request Permission for Notifications

Before you can send notifications, you need to request user permission to do so. You can do this using the following code:


OneSignal.push(function() {
    OneSignal.isPushNotificationsEnabled(function(isEnabled) {
        if (!isEnabled) {
            OneSignal.push(["registerForPushNotifications"]);
        }
    });
});

When the user grants permission, they will start receiving notifications from your PWA.

Step 7: Sending Notifications

Now that OneSignal is integrated and users can opt-in, it's time to send notifications. You can do this either through the OneSignal dashboard or programmatically using their REST API. From the dashboard, navigate to "Messages" and click on "New Push." Fill in the notification details like title, message, and select the audience you want to target. You can also schedule notifications for later delivery.

Step 8: Testing Your Notifications

Once you’ve set up your notifications, it’s crucial to test them. Ensure your PWA is open in a browser and that you've opted in to receive notifications. Send a test notification from the OneSignal dashboard and confirm it appears on your device. Check for any compatibility issues across different devices and browsers.

Conclusion

Implementing PWA push notifications with OneSignal is a straightforward process that can greatly enhance user engagement. By following these steps, you'll be able to seamlessly communicate with your users even when they are not actively using your app. Regularly monitor the analytics provided by OneSignal to optimize your push notification strategy and keep your users informed and engaged.
