Gate Alpine.js UI on Persist hydration (Alpine.plugin + useHydrated / $hydrated). Use when wiring HydrationSignal into Alpine data components.
Gate Angular UI on Persist hydration with useHydrated (readonly Signal). Call inside an injection context; use when avoiding flash of default state on async backends.
Gate Lit element UI on Persist hydration with HydrationController. Use when wiring HydrationSignal into a ReactiveControllerHost; not a hook.
Persist with React Native AsyncStorage via @stainless-code/persist/backends/async-storage. Use for RN string-wire JSON state; always gate with useHydrated.
Compress a string-wire StateStorage with @stainless-code/persist/backends/compressed (gzip/deflate). Backend wrapper — compose with createStorage; stack compress-then-encrypt.
Cross-tab sync for backends without storage events via @stainless-code/persist/transport/crosstab (createBroadcastCrossTab). Wrap storage + pass crossTabEventTarget; call close() on teardown.

Exports nodeFsStateStorage({ dir }) only — compose with createStorage + a codec. One file per key; sanitized name + djb2 hash suffix (collision-safe). Refuses keys that sanitize to . / .. / "". ENOENT → null / no-op remove.
import { createStorage, jsonCodec } from "@stainless-code/persist";
import { nodeFsStateStorage } from "@stainless-code/persist/backends/node-fs";
const storage = createStorage<Prefs>(
() => nodeFsStateStorage({ dir: "./.persist" }),
jsonCodec(),
);
No optional peer for this backend — uses node:fs. Richer graphs → persist-seroval as the codec.
