Implementing the Chat Component

There are two ways to integrate RAG Chat Component into your application:

1. Use of stand-alone component files (recommended): Create a separate component file and use it in the application:

   // components/chat.tsx
"use client";
import { ChatComponent } from "@upstash/rag-chat-component";
export const Chat = () => {
return <ChatComponent />;
};
// page.tsx
import { Chat } from "./components/chat";
export default function Home() {
return (
<>
<Chat />
<p>Home</p>
</>
);
}

2. Integration directly in client components: Import and use ChatComponent directly in the client page:

   // page.tsx
"use client";
import { ChatComponent } from "@upstash/rag-chat-component";
export default function Home() {
return (
<>
<ChatComponent />
<p>Home</p>
</>
);
}

usage example

Below is a simple example of how to use it:

import { ChatComponent } from "@upstash/rag-chat-component";
export default function App() {
return (
<div>
<h1>Welcome to RAG Chat</h1>
<ChatComponent />
</div>
);
}

With the above steps, you can easily integrate and use Upstash RAG Chat Component in your Next.js application to provide powerful AI chat functionality.
