Quick Start

import { AssistantCloud } from "assistant-cloud"; import { useChatRuntime, AssistantChatTransport } from "@assistant-ui/react-ai-sdk"; import { AssistantRuntimeProvider } from "@assistant-ui/react"; import { Thread } from "@/components/assistant-ui/thread"; import { ThreadList } from "@/components/assistant-ui/thread-list";

const cloud = new AssistantCloud({ baseUrl: process.env.NEXT_PUBLIC_ASSISTANT_BASE_URL, authToken: async () => getAuthToken(), });

function Chat() { const runtime = useChatRuntime({ transport: new AssistantChatTransport({ api: "/api/chat" }), cloud, });

return ( <AssistantRuntimeProvider runtime={runtime}> <ThreadList /> <Thread /> </AssistantRuntimeProvider> ); }

Authentication Options

// JWT Token (recommended) const cloud = new AssistantCloud({ baseUrl: process.env.NEXT_PUBLIC_ASSISTANT_BASE_URL, authToken: async () => session?.accessToken, });

// API Key (server-side) const cloud = new AssistantCloud({ baseUrl: process.env.ASSISTANT_BASE_URL, apiKey: process.env.ASSISTANT_API_KEY, userId: user.id, workspaceId: user.workspaceId, });

// Anonymous (public apps) const cloud = new AssistantCloud({ baseUrl: process.env.NEXT_PUBLIC_ASSISTANT_BASE_URL, anonymous: true, });

Cloud API

// Thread operations const threads = await cloud.threads.list(); await cloud.threads.create({ title: "New Chat" }); await cloud.threads.update(threadId, { title: "Updated" }); await cloud.threads.delete(threadId);

// Message operations const messages = await cloud.threads.messages(threadId).list();

// File uploads const { signedUrl, publicUrl } = await cloud.files.generatePresignedUploadUrl({ filename: "document.pdf", }); await fetch(signedUrl, { method: "PUT", body: file });
