How to Create and Download Image from OpenAI API in NodeJS Command Line Script

Openai Image Generator in NodeJS

Learn how to use the OpenAI API to generate and download images from a NodeJS command line script with this step-by-step guide.

Introduction:

Artificial Intelligence is rapidly revolutionizing the world by offering new and innovative solutions to various problems. One such solution is the OpenAI API, which enables developers to create various applications and tools using machine learning models. In this article, we will explore how to generate and download images from the OpenAI API using a NodeJS command line script.

In today’s world, the generation of artificial intelligence has opened doors to limitless possibilities. One such AI-based technology that has gained immense popularity is the OpenAI image generation. In this article, we will discuss the OpenAI image generation in Node.js, its working, and how to use it to generate realistic and high-quality images.

Setting Up Your Environment

1. Install Node.js: The first step is to install Node.js on your system. You can download the latest version from the official nodejs website. You can read my guide how to install NodeJS and NPM.

2. Install a Text Editor: You will need a text editor to write your code. Popular choices include Sublime Text, Atom, and Visual Studio Code.

3. Install a Package Manager: A package manager is a tool that helps you install and manage third-party libraries and packages. Popular choices include npm and Yarn.

Installing Required Dependencies

npm install request

Retrieving Your API Key

Writing script in nodejs in your editor

const request = require('request');

const fs = require('fs');
const https = require('https');

const openai_api_key = 'your-openai-api-key-here';

const args = process.argv.slice(2);
const filename = args[0];
const prompt = args[1];
const size = args[2] || '1024x1024';

const options = {
  url: 'https://api.openai.com/v1/images/generations',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer ' + openai_api_key
  },
  body: {
    prompt,
    'n': 1,
    size
  },
  json: true
};

request.post(options, (err, res, body) => {
  console.log(body.data[0].url);
  https.get(body.data[0].url, (response) => {
    response.pipe(fs.createWriteStream('./' + filename + '.png'));
  });
});

save your nodejs script as: openai-gen-image.js

to run your script in command line use:

node openai-gen-image.js your_filename "example prompt: mountains, rivers"
