FAQ
Service workers are specialized JavaScript assets that act as proxies between web browsers and web servers. They aim to improve reliability by providing offline access, as well as boost page performance.
A: From a page on the same origin, go to Developer Tools > Application > Service Workers. You can also use chrome://inspect/#service-workers to find all running service workers.
Handle notifications in the service worker Add the following code to the end of the file: // Show notification when received self. addEventListener('message', (event) => { let notification = event. data; self.
Service workers are enabled by default in all modern browsers. To run code using service workers, you'll need to serve your code via HTTPS — Service workers are restricted to running across HTTPS for security reasons. A server supporting HTTPS is necessary.
Web workers and service workers Both run in a secondary thread, allowing JavaScript code to execute without blocking the main thread and the user interface. They don't have access to the Window and Document objects, so they can't interact with the DOM directly, and they have limited access to browser APIs.
To test your service worker locally, you need to use a local HTTPS server, such as the one provided by the Web Server for Chrome extension or the serve package for Node. js. This will allow you to access your web app on a local URL with a self-signed certificate, which is accepted by most browsers for testing purposes.
Your application server sends the content of a notification and device s to your push notification service API. Once the server has sent the request to the push notification service, the service sends the notification to your users' devices.
