How To Implement ChatGPT In NodeJS with axios

To implement ChatGPT in Node.js, you can use the OpenAI API to make requests to the GPT-3.5 model. In this tutorial, we will show very basic setup.

Implement ChatGPT In NodeJS example

1. Inside this new project folder create a new package.json file by using the npm command in the following way:

npm init -y

2. Install the axios package to make HTTP requests from Node.js:

npm install axios

3. Create a JavaScript file for your ChatGPT implementation and import the axios package:

const axios = require('axios');

4. Define a function that makes a request to the OpenAI API with your API key and a prompt:

async function getChatResponse(prompt) {
  const response = await axios.post('https://api.openai.com/v1/engines/davinci-codex/completions', {
    prompt: prompt,
    max_tokens: 60,
    n: 1,
    stop: '\n',
  }, {
    headers: {
      'Content-Type': 'application/json',
      'Authorization': 'Bearer ' + process.env.OPENAI_API_KEY,
    },
  });
  return response.data;// .choices[0].text.trim()
}

5. Run code.

node app.js

Output:

Sign up or sign in for OpenAI API access and get your API key.

You can customize the prompt, max_tokens, and stop parameters to generate different kinds of responses. You can also integrate the ChatGPT function with other parts of your Node.js application to create more complex behavior.
