The Application tab in Chrome’s Developer Tools contains a section to inspect and manage Service Workers associated with a PWA. Options available in this section include:
- Offline simulates running the PWA whilst disconnected from the internet, used for testing and debugging offline behaviour.
- Update on reload fetches and installs the latest Service Worker each time the page is refreshed.
- Bypass for network ignores any active Service Worker and fetches resources from the network. When you are working on client-side JavaScript or CSS this ensures you are using the latest version.
The Service Worker section also provides an option to unregister the Service Worker and activating waiting Service Workers.
