1) Define a topic

Topic is a string identifier for the synchronized resource, for example:

• app-config
• auth-state
• settings

Topics are compared strictly (===).

2) Wire the engine

You need 3 parts:

• subscriber (listens for invalidation events)
• provider (fetches snapshots)
• applier (applies snapshots locally)

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

const handle = createRevisionSync({
  topic: 'settings',
  subscriber: myInvalidationSubscriber,
  provider: mySnapshotProvider,
  applier: mySnapshotApplier,
  logger: createConsoleLogger({ debug: true }),
});

await handle.start();

3) Stop (single-use handle)

After stop(), the handle is considered “dead” (to protect against subscription leaks).

handle.stop();
// if you need it again, create a new handle via createRevisionSync(...)
