LiveSmart AI Video – Smart Video Avatars with ChatGPT | Node.js

Introduction

LiveSmart AI Video is a revolutionary technology that allows you to create realistic and engaging video avatars that can interact with your customers in real-time. By combining LiveSmart AI Video with ChatGPT, a cutting-edge language model, you can create a truly immersive experience for your users. In this tutorial, we will guide you on how to use LiveSmart AI Video - Smart Video Avatars with ChatGPT in Node.js. This technology has numerous applications in industries such as e-commerce, customer service, and education, and is perfect for creating interactive experiences for your customers.

Prerequisites

Before we dive into the tutorial, make sure you have the following prerequisites:

• A Node.js development environment set up on your computer
• Familiarity with JavaScript and HTML/CSS
• A LiveSmart AI Video account and an API key
• A ChatGPT API key
• A text editor or IDE of your choice

Step 1: Set up your development environment

To get started, create a new Node.js project by running the following command in your terminal:

npm init -y

This will create a new file called package.json in your project directory. Next, install the required dependencies by running the following command:

npm install express body-parser

This will install the Express.js web framework and the body-parser middleware.

Step 2: Create a LiveSmart AI Video avatar

To create a LiveSmart AI Video avatar, you need to upload a video file and configure the avatar settings. You can do this by following these steps:

1. Go to the LiveSmart AI Video dashboard and click on the "Avatars" tab.
2. Click on the "Create Avatar" button and upload a video file.
3. Configure the avatar settings, such as the animation style and mouth movements.
4. Click on the "Save" button to create the avatar.

Once you have created the avatar, you can obtain an API key by clicking on the "API" tab and copying the API key.

Step 3: Integrate LiveSmart AI Video with ChatGPT

To integrate LiveSmart AI Video with ChatGPT, you need to create a Node.js script that makes API calls to both services. Create a new file called index.js in your project directory and add the following code:

const express = require('express');
const bodyParser = require('body-parser');
const axios = require('axios');

const app = express();
app.use(bodyParser.json());

const liveSmartAPIKey = 'YOUR_LIVE_SMART_API_KEY';
const chatGPTAPIKey = 'YOUR_CHAT_GPT_API_KEY';
const avatarId = 'YOUR_AVATAR_ID';

app.post('/api/handleChat', (req, res) => {
  const userInput = req.body.input;

  // Make a request to the ChatGPT API to get a response
  axios.post(`https://api.chatgpt.com/v1/messages`, {
    message: userInput,
    key: chatGPTAPIKey
  })
 .then(response => {
    const chatResponse = response.data.message;

    // Make a request to the LiveSmart AI Video API to render the avatar
    axios.post(`https://api.livesmart.ai/video/v1/render`, {
      avatarId: avatarId,
      text: chatResponse,
      apiKey: liveSmartAPIKey
    })
   .then(response => {
      res.send(response.data);
    })
   .catch(error => {
      console.error(error);
      res.status(500).send('Error rendering avatar');
    });
  })
 .catch(error => {
    console.error(error);
    res.status(500).send('Error getting ChatGPT response');
  });
});

app.listen(3000, () => {
  console.log('Server started on port 3000');
});

Replace YOUR_LIVE_SMART_API_KEY, YOUR_CHAT_GPT_API_KEY, and YOUR_AVATAR_ID with your actual API keys and avatar ID.

Step 4: Test the integration

To test the integration, run the following command in your terminal:

node index.js

This will start the Express.js server and make the API endpoint available at http://localhost:3000/api/handleChat. You can test the integration by sending a POST request to this endpoint with a JSON body containing the user's input.

For example, you can use the curl command to send a POST request:

curl -X POST 
  http://localhost:3000/api/handleChat 
  -H 'Content-Type: application/json' 
  -d '{"input": "Hello, how are you?"}'

This should render the LiveSmart AI Video avatar and display the chat response. You can then interact with the avatar and see the conversation in action.

Conclusion

In this tutorial, we have shown you how to use LiveSmart AI Video - Smart Video Avatars with ChatGPT in Node.js. By following these steps, you can create a realistic and engaging video avatar that can interact with your customers in real-time. With the integration of ChatGPT, you can provide personalized and accurate responses to your users' questions, making it an ideal solution for industries such as e-commerce, customer service, and education.
