Web App Offline Cache: Avoid Stale Critical Data
A service worker shows an old page while the server has a new version. This guide gives you a small, testable way to approach the issue before changing a live system.
A practical workflow
- Choose a caching strategy by resource: static assets, API data and user records have different needs.
- Test updates and offline behavior after a deployment.
What to check
Do not cache sensitive or payment state without an explicit consistency and security plan. Compare the result with the original problem and record what changed. If a measurement or test does not support the change, revisit the assumption rather than adding more complexity.
Keep the experiment small enough to reverse. Document the starting state, the change and the result so another person can repeat the process. Product menus and versions can change, so check the current documentation for your environment.
