Chat History for AI SDK

Overview

With the help of assistant-cloud, you can add thread management and thread history capabilities to assistant-ui. This guide will walk you through the process of integrating assistant-cloud with the AI SDK by Vercel.

Prerequisites

You need an assistant-cloud account to follow this guide. You can sign up here: https://cloud.assistant-ui.com/

Setting up assistant-cloud project in your react project:

1. Create a new project on the assistant-cloud dashboard and copy the Frontend API URL (https://proj-[ID].assistant-api.com) from the settings page.
2. Add the url as an environment variable NEXT_PUBLIC_ASSISTANT_BASE_URL

NEXT_PUBLIC_ASSISTANT_BASE_URL=[YOUR_FRONTEND_API_URL]

3. Create a client side AssistantCloud instance. Note: this will create an anonymous user id that is tied to the user's browser session. For connecting to an auth provider to persist threads for a user based on a workspace and/or user id, look at Cloud Authorization Docs.

"use client";
import {
  AssistantCloud,
  AssistantRuntimeProvider,
  ThreadList,
  Thread
} from "@assistant-ui/react";
import { useChatRuntime } from "@assistant-ui/react-ai-sdk";
 
 
const cloud = new AssistantCloud({
  baseUrl: process.env["NEXT_PUBLIC_ASSISTANT_BASE_URL"]!,
  anonymous: true,
});
 
 
const runtime = useChatRuntime({
  api: "/api/chat",
  cloud,
});
 
 return (
  <AssistantRuntimeProvider runtime={runtime}>
    <div className="grid h-dvh grid-cols-[200px_1fr] gap-x-2 px-4 py-4">
      <ThreadList />
      <Thread />
    </div>
  </AssistantRuntimeProvider>
);
