Replay

Replay records a bounded session of status, transition, context, blocked-navigation, and error observations.

import { createReplayPlugin } from "@rxova/journey-core/plugins";

const machine = createLinearJourney(definition, {
  plugins: [createReplayPlugin({ maxEntries: 500, captureSnapshots: true })]
});

API

const replay = machine.plugins.replay;

replay.getReplaySession();
replay.exportReplaySession({ pretty: true });
replay.clearReplaySession();

The session contains startedAt and a bounded entries array. Each entry has at, kind, data, and, when enabled, a serialized snapshot.

clearReplaySession() resets both the entries and session start time. The snapshot extension exposes { entryCount }.

Options

Option	Meaning
`maxEntries`	Ring-buffer capacity; default `500`, minimum `1`.
`captureSnapshots`	Attach a serializable snapshot to each entry; default `true`.
`now`	Injectable clock.

Serialization converts unsupported values to safe representations; use the exported toSerializable and serializeReplaySession helpers when building related tooling.
