? Build an AI Image Generator in JavaScript! (Super simple!)

Introduction

In this article, we'll walk you through the process of building a simple AI image generator using the OpenAI API, specifically the DALL-E model. This straightforward tutorial is perfect for beginners who want to learn how to create their own projects using the OpenAI API. We'll be utilizing JavaScript, HTML, and CSS to generate images based on text prompts.

Getting Started

Before we jump into the coding part, let’s take a moment to explore API layer, a marketplace of curated APIs. You can find various APIs to incorporate into the app we are building, such as smart image cropping APIs.

Create a Project: Start with a new project in your preferred code editor. We will create three files: index.html, app.js, and styles.css.

Setup index.html: In this file, set up the HTML boilerplate and link the JavaScript and CSS files.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" href="styles.css">
    <title>AI Image Generator</title>
</head>
<body>
    (* Content will go here *)
    <script src="app.js"></script>
</body>
</html>

Create Background

Generate or Customize Background: You can create a custom background using an online SVG generator.
Add Background to HTML: Once you have your SVG, you can embed it directly into your HTML and style it using CSS.

HTML Structure

In your index.html, create the necessary elements:

Header: An h1 element for your title
Image Section: A section for displaying generated images
Input Section: A container for user input and a submit button

<body>
    <h1>AI Image Generator</h1>
    <section class="image-section"></section>
    <section class="input-container">
        <input type="text" id="prompt-input" placeholder="Enter your prompt here">
        <div id="submit-icon">➤</div>
    </section>
</body>

CSS Styling

Set the CSS for body, header, and sections to center the elements and establish a consistent layout.
Utilize Flexbox for alignment, spacing, and responsiveness.

body (
    display: flex;
    flex-direction: column;
    justify-content: space-between;
    align-items: center;
    height: 100vh;
    margin: 0;
    background-color: #f0f0f0;
)

h1 (
    color: white;
)

JavaScript Functionality

API Key Safety: Begin by acquiring your OpenAI API key from the OpenAI website. Avoid posting this key publicly.
Fetch API: Use the Fetch API to send a POST request to OpenAI's DALL-E model using the text input prompt to retrieve images.

const API_KEY = 'YOUR_API_KEY_HERE';
const submitIcon = document.getElementById('submit-icon');

submitIcon.addEventListener('click', async () => (
    const inputElement = document.getElementById('prompt-input');
    const prompt = inputElement.value;
    const response = await fetch('https://api.openai.com/v1/images/generations', {
        method: 'POST',
        headers: {
            'Authorization': `Bearer ${API_KEY)`,
            'Content-Type': 'application/json'
        },
        body: JSON.stringify(( prompt, n: 4, size: "1024x1024" ))
    });
    const data = await response.json();
    // Handle the resulting data here
});

Handle and Display Images: Create new image elements based on the URLs returned by the API and append them to the image section.

data.data.forEach(imageObject => (
    const imgContainer = document.createElement('div');
    const imgElement = document.createElement('img');
    imgElement.src = imageObject.url;
    imgContainer.appendChild(imgElement);
    document.querySelector('.image-section').appendChild(imgContainer);
));

Conclusion

You now have a functioning AI image generator using the OpenAI API! This project serves as a launching point for more complex applications, including uploads and backend integration for added functionality.
