is rapidly changing the way we interact with technology. One of the most significant recent advances has been the development of ChatGPT by - an AI research lab that produces some of the most advanced AI models in the world. This powerful tool has already gained recognition in , , and other fields! Artificial Intelligence (AI) OpenAI natural language processing computer vision reinforcement learning, is one of the largest and most intelligent language models, used widely in education, mental health support, customer service, personal assistance, and entertainment. ChatGPT In this article, we'll discuss how OpenAI can enhance JavaScript File API usage to create smarter apps capable of performing complex tasks, thereby increasing business revenue. This discussion will provide you with a new perspective and confidence to utilize OpenAI for future projects. What is the JavaScript File API? The allows developers to access and manipulate files directly from the browser. By using File API, developers can create web apps that can carry out file-related operations, such as uploading and downloading files, validating user input, and performing various other file manipulations. JavaScript File API you’ll find the bare essentials we need to know about the File API to confidently proceed to other sections. Here Files are represented as objects which include individual File objects. Every object provides access to metadata such as , , , and . In order to access file contents we can simply pass objects to FileReader. FileList File file's name size type last modified date File The method provided by the  FileReader interface is used to read the contents of the specified or . When the read operation is finished, the becomes , and the is triggered. At that time, the attribute contains the data as a data: URL representing the file's data as a encoded string. readAsDataURL Blob File readyState DONE loadend result base64 Nowadays there are plenty of advanced tools like FileStack that help you simplify file upload and management and automate much of routine work for you. In this story, we’ll focus on file management using the . vanilla File API Setup Open AI OpenAI has a well-written official documentation - - that opens up a broad range of natural language processing capabilities like chatbots, virtual assistants, and other conversational interfaces. They even have a nice guide to get acquainted with key concepts through hands-on and interactive examples. So if you feel like you’re new to it, don’t pass around it. platform.openai.com QuickStart The next thing we should care about is API keys. In order to use OpenAI API in Javascript, we will need an to authenticate and authorize our requests to their servers. An is a security token that identifies our account when we access OpenAI API services. Without an , your requests will be rejected, and you will not be able to access OpenAI API. So first we must create an account on the OpenAI’s platform and generate an API key - - see below. API Key API Key API Key Platform API Keys The registration process is fairly straightforward: you merely - and you’re good to go! But should you have any questions or obstacles, don’t hesitate to drop me a line. I’ll be glad to be of service to assist you or create a separate story for that. add a new secret key Leverage OpenAI with File API The integration of and empowers developers to build intelligent applications capable of executing intricate tasks such as , , , and more. By combining the power of language models with the file manipulation capabilities of , we can develop advanced new-level apps that can automatically generate text content based on user input or perform advanced text analytics on large datasets. OpenAI JavaScript File API content curation data analysis predictive analytics OpenAI's JavaScript File API Let’s cut to the chase and look over how OpenAI can be used with the File API in the example of Smart Image Recognition. With the help of advanced image recognition models, can be enhanced to identify images and classify them accordingly. To tailor the image recognition feature we’ll be using the following endpoints: OpenAI's JavaScript File API 1. https://api.openai.com/v1/images/gpt
2. https://api.openai.com/v1/images/generations Then with the help of we’re going to read the file selected by the user and convert it to format. This is what the above expect. We then send the Base64-encoded image to OpenAI's image recognition model, which identifies the image and returns the classification results. File API, Base64 endpoints Let’s take a glance at a general example of how we can utilize here and print the : Open AI API image classification results // Get the image file from the input element
const input  = document.querySelector('input[type="file"]');
// Get a File object from the FileList
const imageFile = input.files[0];
// Initiate a file reader to analyze file contents further
const reader = new FileReader();
// Define OpenAI API Key we generated earlier
const apiKey = '<HACKERNOON API KEY>';

// Read file contents
reader.readAsDataURL(imageFile);

// Add an "onload" handler that'll be invoked as soon as the file is loaded
reader.onload = async function() {
  // Parse image content as Base64 format 
  const base64Image = reader.result.replace(/^data:image\/(png|jpg|jpeg);base64,/, '');
  // Fetch image classification results
  const response = await fetch('https://api.openai.com/v1/images/gpt', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${apiKey}`,
    },
    body: JSON.stringify({ image: base64Image }),
  });
  // Parse the response from OpenAI as JSON
  const result = await response.json();
  // Print the result in the console
  console.log(result);
}; We can even go far beyond and reap other powerful Open AI benefits with the Images API like: Images Generation We can create brand new images from scratch based on a text prompt - Images Generation: Here’s the code sample: const input = document.querySelector('input[type="file"]');

input.addEventListener('change', async (event) => {
  const file = input.files[0]; // or event.target.files[0];
  const reader = new FileReader();

  reader.onload = async () => {
    const base64Image = reader.result.replace(/^data:image\/(png|jpg|jpeg);base64,/, '');
    const response = await fetch('https://api.openai.com/v1/images/generations', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${apiKey}`,
      },
      body: JSON.stringify({
        model: 'image-alpha-001',
        prompt: 'a close up, studio photographic portrait of a white siamese cat that looks curious, backlit ears',
        image: base64Image,
      }),
    });

    const result = await response.json();
    const imageUrl = result.data[0].url;

    const generatedImage = document.createElement('img');
    generatedImage.src = imageUrl;
    document.body.appendChild(generatedImage);
  };

  reader.readAsDataURL(imageFile);
}); Images Editing Apart from that we can extend or create edits of an existing image based on a new text prompt - Edit Images: Here’s how we can achieve it: const input = document.querySelector('input[type="file"]');
const imageFile = input.files[0];

const formData = new FormData();
formData.append('image', imageFile);

const response = fetch('https://api.openai.com/v1/images/generations', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': `Bearer ${apiKey}`
  },
  body: JSON.stringify({
    model: 'image-alpha-001',
    prompt: 'a sunlit indoor lounge area with a pool containing a flamingo',
    response_format: 'url',
    image_size: [512, 512],
    image_crop: [1.0, 1.0],
    image_rotate: 0.0,
    image_translate: [0.0, 0.0],
    response_format: 'url',
    target_images: [formData],
  }),
});

const result = await response.json();
const imageUrl = result.data[0].url;

const generatedImage = document.createElement('img');
generatedImage.src = imageUrl;
document.body.appendChild(generatedImage); Images Variations On top of that, we also create variations of existing images: Here’s how it can be done: const input = document.querySelector('input[type="file"]');

input.addEventListener('change', async (event) => {
  const imageFile = input.files[0]; // or event.target.files[0];
  const reader = new FileReader();

  reader.onload = async () => {
    const base64Image = reader.result.replace(/^data:image\/(png|jpg|jpeg);base64,/, '');
    const response = await fetch('https://api.openai.com/v1/images/generations', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${apiKey}`,
      },
      body: JSON.stringify({
        model: 'image-alpha-001',
        prompt: `generate variations of this image: ${base64Image}`,
        size: 512,
        response_format: 'url',
      }),
    });

    const result = await response.json();
    const imageUrl = result.data[0].url;

    const generatedImage = document.createElement('img');
    generatedImage.src = imageUrl;
    document.body.appendChild(generatedImage);
  };

  reader.readAsDataURL(imageFile);
}); Looks impressive, isn’t it? Give it a shot yourself and let me know if you want to see other usages!
