Transcripts

Transcripts let you save and restore session history. This enables persistent conversations across process restarts.

Exporting a Transcript

Every session has a transcript property:

const session = new LanguageModelSession();
await session.respond("My name is Cody.");
await session.respond("I work on open source.");

// Export as JSON string
const json = session.transcript.toJson();

// Or as a dictionary object
const dict = session.transcript.toDict();

Restoring a Session

Create a new session from a saved transcript:

import { Transcript, LanguageModelSession } from "tsfm-sdk";

// From JSON string
const transcript = Transcript.fromJson(json);
const resumed = LanguageModelSession.fromTranscript(transcript);

// From dictionary object
const transcript = Transcript.fromDict(dict);
const resumed = LanguageModelSession.fromTranscript(transcript);

The restored session has full context of the previous conversation:

const reply = await resumed.respond("What's my name?");
// The model remembers: "Your name is Cody."

Full Example

// First session
const session = new LanguageModelSession();
await session.respond("My name is Cody.");
const json = session.transcript.toJson();
session.dispose();

// Later — resume from saved transcript
const resumed = LanguageModelSession.fromTranscript(Transcript.fromJson(json));
const recall = await resumed.respond("What's my name?");
console.log(recall); // References "Cody"
resumed.dispose();

WARNING

Access session.transcript before calling session.dispose(). The transcript reads from the native session pointer, which is freed on dispose.
