makePersistedAdapter

makePersistedAdapter(options): Adapter

Defined in: packages/@livestore/adapter-web/src/web-worker/client-session/persisted-adapter.ts:157

Creates a web adapter with persistent storage (currently only supports OPFS). Requires both a web worker and a shared worker.

On browsers without SharedWorker support (e.g. Android Chrome), this adapter automatically falls back to single-tab mode. In single-tab mode:

Each tab runs independently with its own leader worker
Multi-tab synchronization is not available
Devtools are not supported

Parameters

options

Returns

Adapter
