takeSnapshot

(…storeNames: ?string

AltStore): string

Take snapshot provides you with the entire application’s state serialized to JSON, by default, but you may also pass in stores to take a snapshot of a subset of the application’s state.

Snapshots are a core component of alt. The idea is that at any given point in time you can takeSnapshot and have your entire application’s state serialized for persistence, transferring, logging, or debugging.

var snapshot = alt.takeSnapshot();
var partialSnapshot = alt.takeSnapshot(Store1, Store3);

You can bootstrap a snapshot into your application using alt.bootstrap
