fetch images of cars from google and sort them by color in javascript

To fetch images of cars from Google in JavaScript, we can use the Google Custom Search API. We need to create a Custom Search Engine and obtain the API key and Search engine ID. Once we have these, we can make a GET request to the API using fetch() method or any HTTP client library.

To sort images by color, we can use color extraction libraries like color-thief or node-vibrant. These libraries can extract the dominant color from an image and sort the images based on the dominant colors.

Here's an example code snippet:

index.tsx
const fetch = require('node-fetch');
const ColorThief = require('color-thief');

const API_KEY = 'YOUR_API_KEY';
const SEARCH_ENGINE_ID = 'YOUR_SEARCH_ENGINE_ID';

// Fetch images from Google Custom Search API
async function fetchImages(query) {
  const res = await fetch(`https://www.googleapis.com/customsearch/v1?key=${API_KEY}&cx=${SEARCH_ENGINE_ID}&q=${query}&searchType=image&num=10`);
  const data = await res.json();
  return data.items;
}

// Sort images by dominant color
async function sortImagesByColor(query) {
  const images = await fetchImages(query);
  const colorThief = new ColorThief();
  const coloredImages = [];
  
  for (let i = 0; i < images.length; i++) {
    const img = images[i];
    const dominantColor = await colorThief.getColor(img.link);
    const coloredImage = {
      imageURL: img.link,
      dominantColor
    };
    coloredImages.push(coloredImage);
  }

  coloredImages.sort((a, b) => {
    const c1 = a.dominantColor;
    const c2 = b.dominantColor;
    // Sort by hue, saturation, and value
    return c1[0] - c2[0] || c1[1] - c2[1] || c1[2] - c2[2];
  });

  return coloredImages;
}

// Usage
sortImagesByColor('red sports car')
  .then(images => console.log(images));

In the above example, we first fetch 10 images of "red sports car" from the Google Custom Search API using our API key and search engine ID. Then, for each image, we extract the dominant color using ColorThief.getColor() method. We store the image URL and the dominant color as an object and push it to an array. Finally, we sort the colored images by hue, saturation, and value using Array.sort() method.

Note that this code requires node-fetch and color-thief npm packages to run.
