Live Demo

Explore the live demo showcasing image optimization using the Next.js Image component: Image Optimization Demo

Overview

Project Insight: 📚

This documentation outlines the features and implementation details for optimizing images using the Next.js Image optimizations. The primary focus is on ensuring responsive, visually appealing images while maintaining performance.

Features

1. Envalid Library Integration

• Safely type .env variables using the envalid library to enhance security and maintainability.

2. Personalized Aspect Ratio for Each Image

• Achieve a personalized aspect ratio for images based on their original width and height, ensuring a visually consistent display.

3. External API (Pexels) Integration

• Integrate the Pexels API seamlessly by adding it to the remotePatterns in the next.config.js file.

  const nextConfig = {
    images: {
      remotePatterns: [
        {
          protocol: "https",
          hostname: "images.pexels.com",
          port: "",
          pathname: "/photos/**",
        },
      ],
    },
  };
  
  module.exports = nextConfig;

4. Proper Scaling with object-fit: contain

• Apply object-fit: contain; to images for proper scaling within their parent containers, ensuring an aesthetically pleasing layout.

5. Dynamic Image Sizing with sizes Property

• Utilize the sizes attribute along with tools like respimagelint to automatically calculate optimal image sizes for different devices.

6. Blurring Effect for Dynamic Images

• Implement a blurring effect for dynamic images using the blurDataURL property. Tools like Plaiceholder can assist in generating base64 image data.

  • Schema property for blurred effect:

    blurredDataUrl: z.string().optional(),

7. Calculating Width and Height Ratios

• Calculate image dimensions based on specific width and height values, ensuring accurate display and layout.

  const widthHeightRatio = photo.height / photo.width;
  const galleryHeight = Math.ceil(250 * widthHeightRatio);
  const photoSpans = Math.ceil(galleryHeight / 10) + 1;
