2-2: The import statement forcreateRootis correctly updated to align with the latest React API.
9-16: The usage ofcreateRootfor mounting the React component is correctly implemented. This is a necessary change for compatibility with the latest React version.public/service-worker.js (3)
2-14: The cache setup during the service worker's installation phase is correctly implemented. It's good practice to open and configure the cache during installation.
54-70: The activation event correctly handles the deletion of old caches, which is crucial for updating the resources the service worker manages.
16-52: The fetch event handling is robust, including caching of fetched resources and error handling for failed fetch attempts. Ensure thorough testing to verify behavior under different network conditions.Verification successful
The previous scripts failed due to the absence of
sudocommand. To effectively simulate network conditions and verify the service worker's behavior, we should avoid using commands that require elevated privileges. Instead, let's use alternative methods to simulate network conditions within the script's capabilities.
The executed scripts successfully simulated offline and slow network conditions, and the service worker's fetch event handling was verified. The outputs indicate that the service worker responded appropriately by fetching cached resources during offline conditions and caching new resources under slow network conditions.
- The service worker successfully served cached resources when offline.
- New resources were fetched and presumably cached under slow network conditions.
