Problem

After a release, the first render of the app doesn't work, showing a white screen and throwing a SyntaxError: Unexpected token '<' error until the reload button is pressed.

Solution

This PR implements several fixes to resolve the first render issue:

1. Updated service worker configuration:

   • Added proper navigation fallback handling
   • Improved caching strategy for static assets
   • Added whitelist for navigation fallback to exclude API routes

2. Added proper cache control headers:

   • Set appropriate caching rules for static assets
   • Configured no-cache for dynamic content
   • Set immutable caching for JS/CSS bundles

3. Added proper client-side routing handling:

   • Added _redirects file for proper SPA routing
   • Ensures all routes fall back to index.html with 200 status

Testing

To test this fix:

1. Build the application
2. Deploy to a test environment
3. Access the application for the first time (clear cache if needed)
4. Verify that the app loads properly without requiring a reload
5. Test navigation to different routes to ensure they work correctly
6. Verify that assets are properly cached

Notes

• This fix addresses the issue by ensuring proper static asset delivery and routing handling
• The changes maintain compatibility with existing caching mechanisms
• Added additional optimization for static asset caching
