Persistence

Overview​

By default, Kritzel uses an empty provider list (providers: []), so canvas state resets on page reload. To persist data locally in the browser, configure syncConfig with IndexedDBSyncProvider.

IndexedDB persistence is ideal when you want users to keep their canvas state across reloads and browser restarts on the same device.

Persisting Canvas State with IndexedDB​

Configure IndexedDBSyncProvider in syncConfig.providers to make object state durable in the browser.

  • Sync configuration (syncConfig, KritzelSyncConfig)
  • Local persistence provider (IndexedDBSyncProvider)
  • Provider list (syncConfig.providers)
