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.

@stainless-code/persist/sources/valtio maps a proxy object through snapshot / Object.assign / subscribe (valtio/vanilla) onto persistSource.
proxy({…}) object state and want it to survive reload.bun add @stainless-code/persist valtio
valtio is an optional peer of /sources/valtio.
import { proxy } from "valtio";
import { createJSONStorage } from "@stainless-code/persist";
import { persistProxy } from "@stainless-code/persist/sources/valtio";
const prefs = proxy({ theme: "light" as const });
const persist = persistProxy(prefs, {
name: "app:prefs:v1",
storage: createJSONStorage(() => localStorage),
});
Writes apply with Object.assign(proxy, next) — keys absent from next are not deleted. Design partialize / migrate so hydrate payloads carry the shape you need, or reset keys yourself.
TState extends object.destroy() for non-singleton proxies.persistProxy(proxyObject, options) → PersistApiPersistApi: same as persistSourceSee also: persist-mobx — same object + assign pattern with runInAction.
