The amp-web-push component allows users to subscribe to web push notifications.
amp-web-push component in the header.
<script async custom-element="amp-web-push" src="https://cdn.ampproject.org/v0/amp-web-push-0.1.js" ></script>
amp-form component is being used in this demo, to send a post request so the notification can be prepared and sent.
<script async custom-element="amp-form" src="https://cdn.ampproject.org/v0/amp-form-0.1.js" ></script> <script async src="https://cdn.ampproject.org/v0.js"></script> </head> <body>
amp-web-push component requires two additional HTML files as well as an amp-web-push compatible Service Worker. These three files form the configuration described below.
<amp-web-push id="amp-web-push" layout="nodisplay" helper-iframe-url="https://amp.dev/documentation/examples/components/amp-web-push/amp-web-push-helper-frame.html" permission-dialog-url="https://amp.dev/documentation/examples/components/amp-web-push/amp-web-push-permission-dialog.html" service-worker-url="https://amp.dev/documentation/examples/components/amp-web-push/sw.js" service-worker-scope="https://amp.dev/documentation/examples/components/amp-web-push/" > </amp-web-push>
Clicking the subscription widget pops up a page prompting the user for notification permissions and signals the service worker (configured below) to subscribe the user to push in the background. On this example, we are intercepting the call to
onMessageReceivedSubscribe, and storing the subscription object on IndexedDB.
<amp-web-push-widget visibility="unsubscribed" layout="fixed" width="500" height="70" > <button on="tap:amp-web-push.subscribe"> Subscribe to Notifications </button> </amp-web-push-widget>
Clicking the unsubscription widget signals the worker to unsubscribe the user from push in the background. On this example, we'll be also removing the previoulsy stored subscription object from IndexedDB.
<amp-web-push-widget visibility="subscribed" layout="fixed" width="500" height="180" > <button on="tap:amp-web-push.unsubscribe"> Unsubscribe from Notifications </button> <form method="post" action-xhr="https://amp.dev/documentation/examples/components/amp-web-push/send-push" target="_top"> <input type="submit" value="Send Web Push" /> <div submitting>Sending Push message...</div> <div submit-success>Web Push sent!</div> <div submit-error>Something went wrong.</div> </form> </amp-web-push-widget> <amp-web-push-widget visibility="blocked" layout="fixed" width="250" height="80" > Looks like you've blocked notifications! </amp-web-push-widget>
