state-syncReliable state synchronization between windows/processes

Invalidation → Fetch snapshot → Apply (revision gate)

Quickstart

Packages

Lifecycle

Framework-agnostic

Works with Pinia/React/vanilla state via applier adapters.

Transport-agnostic

Any IPC/transport (Tauri events+invoke, BroadcastChannel, in-memory) via subscriber/provider.

Deterministic

Monotonic revisions + snapshot source of truth guard against out-of-order events.

Production-friendly

Contract tests, strict protocol validation, and observability via phases.

Install

bash

npm install @statesync/core
npm install @statesync/pinia   # if Pinia
npm install @statesync/tauri   # if Tauri

Quick example

import { createConsoleLogger, createRevisionSync } from '@statesync/core';

const handle = createRevisionSync({
  topic: 'app-config',
  subscriber: mySubscriber,
  provider: myProvider,
  applier: myApplier,
  logger: createConsoleLogger({ debug: true }),
});
