Using OpenAI API with Node.js

Introduction

This tutorial demonstrates how to integrate and use the OpenAI API with Node.js to leverage advanced AI capabilities in your applications.

1. Setting Up Your OpenAI API Key

Before starting, make sure you have your OpenAI API key ready. You can obtain it from the OpenAI website after signing up for an account.

2. Making API Requests

To make requests to the OpenAI API using Node.js, you'll use the `axios` library for HTTP requests.

Text Completion

Here’s an example of making a request for text completion:

const axios = require('axios');

const apiKey = 'YOUR_API_KEY_HERE';
const url = 'https://api.openai.com/v1/completions';

axios.post(url, {
    prompt: 'Translate English to French: Hello, how are you?',
    max_tokens: 50
}, {
    headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${apiKey}`
    }
})
.then(response => {
    console.log(response.data.choices[0].text.trim());
})
.catch(error => {
    console.error('Error:', error);
});
                    

This Node.js script sends a POST request to the OpenAI API for text completion and logs the API response.

Code Generation

Here’s an example of making a request for code generation:

const axios = require('axios');

const apiKey = 'YOUR_API_KEY_HERE';
const url = 'https://api.openai.com/v1/engines/davinci-codex/completions';

axios.post(url, {
    prompt: 'Generate Python code to sort an array using bubble sort',
    max_tokens: 150,
    stop: ['\n']
}, {
    headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${apiKey}`
    }
})
.then(response => {
    console.log(response.data.choices[0].text.trim());
})
.catch(error => {
    console.error('Error:', error);
});
                    

def sort_list(list):
    list.sort()
    return list

my_list = [3, 1, 4, 2]
print(sort_list(my_list))
                    

This Node.js script sends a POST request to the OpenAI Codex engine for code generation and logs the generated code.

3. Handling Responses

Once you receive a response from the API, you can handle it in your Node.js code.

Text Completion

Here’s how you might handle the completion response:

// Assuming `response` contains the API response object
console.log(response.data.choices[0].text.trim());
                    

In this example, `response` contains the JSON response from the OpenAI API.

Code Generation

Here’s how you might handle the code generation response:

// Assuming `response` contains the API response object
console.log(response.data.choices[0].text.trim());
                    

In this example, `response` contains the JSON response from the OpenAI API with the generated code.
