Get Started With NLUX React 🚀

The example below demonstrates how to create an AI chat interface using NLUX React and LangChain, the open source framework for building LLM backends. But you can use NLUX with any LLM ― either via the standard adapters provided, or by creating your own adapter.

To get started with NLUX React and LangChain, install the @nlux/react and @nlux/langchain-react packages:

npm install @nlux/react @nlux/langchain-react

Then include <AiChat /> in your React app to get started. Use the useChatAdapter hook to configure an adapter for your LLM.

import {AiChat} from '@nlux/react';
import {useChatAdapter} from '@nlux/langchain-react';

const App = () => {
    const gptAdapter = useChatAdapter({
        url: 'https://<Your LangServe Runnable URL>'
    });

    return (
        <AiChat
            adapter={gptAdapter}
            composerOptions={{
                placeholder: 'How can I help you today?'
            }}
            conversationOptions={{
                historyPayloadSize: 'max'
            }}
        />
    );
}

You should also include the NLUX theme CSS file in your HTML page or import it in your React app.

And The Result Is ✨

An AI chatbot, powered by LangChain, that can understand and respond to user messages:

Theme File and CSS 🎨

You should include a theme CSS file into your HTML page. The recommended way for React developers is to install @nlux/themes

npm install @nlux/themes

Then import the theme CSS file into your app or component as follows:

import '@nlux/themes/nova.css';

This requires that your bundler is configured to load CSS files.
