Research: PWA SW Updates & Offline Write Safety

Hypothesis

With cache versioning and cautious update prompts, we can avoid data loss during app updates and schema bumps while offline.

Questions

  • Best timing for SW activation without disrupting writes
  • Handling schema migrations when a stale SW is cached
  • Safe rollback strategy

Method

  • Simulate offline state; bump schema; observe SW activation and data integrity

Acceptance

  • No data loss or corruption across update/migration
  • Clear UX for update available and post-update state

Deliverables

  • SW update policy, cache naming, migration/rollback checklist
