Overview

Chat SDK now supports cross‑platform conversation history through the new transcripts and identity options. User transcripts persist across every platform adapter, allowing the same user to keep their message history wherever they message your bot.

Example

import { Chat } from "chat";

const bot = new Chat({
  userName: "mybot",
  identity: ({ author }) => author.email ?? null,
  transcripts: {
    retention: "30d",
    maxPerUser: 200,
  },
  // ...
});

Identify users by email and keep up to 200 messages per user for 30 days.

Transcripts API

bot.transcripts exposes four methods, backed by your existing state adapter:

• append – persist an inbound message or a bot reply
• list – return entries chronologically with filters
• count – total entries stored for a user
• delete – wipe every entry for a user
