What are service workers and how do they work?
Service workers are scripts that run in the background of a web application, separate from the main browser thread. They enable features like offline access, background sync, and push notifications.
Can you explain how to register a service worker?
To register a service worker, you use the navigator.serviceWorker.register()
method in your JavaScript code, typically in the main script of your web app.
What are some common use cases for service workers?
Common use cases include caching assets for offline use, intercepting network requests to serve cached content, and enabling push notifications.
Are there any limitations to using service workers?
Yes, service workers only work over HTTPS, and they have a lifecycle that can be complex to manage, especially with updates.
