Testing Instructions
How to test the offline flag and tracking
Setup:
Stop your dev server
Close Chrome completely and uninstall any existing PWA
Start the dev server: yarn dev
Go to http://localhost:7081/mundo/live/c7dkx155e626t?renderer_env=local
Install it as a PWA (click the install icon in the address bar)
Test the flag:
Once installed, refresh the page to make sure the offline page gets cached
Open DevTools, go to Network tab and set it to Offline
Refresh the page - you should see the custom offline page
Check Local Storage (in DevTools → Application → Local Storage)
You should see offline_page_visit with value "true"
Test the tracking event:
While still on the offline page with the flag set
Open the Console tab in DevTools
Switch Network back to Online
You should see a tracking beacon fire with event name pwa-offline-page-view and network type
Check Local Storage again - the offline_page_visit flag should be gone
Test it fires again:
Go offline again, refresh to see the offline page
The flag gets set again
Go back online
The event fires again and the flag is removed
That's it. The event should fire every time you go from offline → online after visiting the offline page.
