Offline Recovery & UniApp Migration

Connect message synchronization and move away from the unmaintained UniApp SDK.

Before production

  • Use wss:// and verify certificates, reverse-proxy WebSocket Upgrade, and CSP.
  • Some console output in 1.3.5 is not controlled by config.debug and can contain decoded message data. Apply an approved removal or redaction approach and inspect the final bundle.
  • Keep tokens in memory or controlled session storage; exclude them from URLs, analytics, error reporting, and browser logs.
  • Test network loss, sleeping tabs, expired tokens, kicks, offline deduplication, account switching, and rollback.

Channels
