Optimizing Images Using a Node.js Script

If you are looking for a way to optimize images in your Node.js applications, one tool that you should consider using is sharp. Sharp is a powerful image processing library that provides a wide range of functionalities.

To get started, you will need to import the sharp module:

1	import sharp from 'sharp';

Once you have imported the module, you can use the sharp function to perform various image optimizations. One common task is converting images to the webp format. Here is an example of how to convert an image to webp:

1
2
3

await sharp('image.png')
  .webp({ lossless: true })
  .toFile('image.webp');

The sharp function takes the path to the input image file as the parameter. In the example above, we are converting the image.png file to webp format with lossless compression. The resulting webp image is then saved as image.webp.

Aside from converting images to webp, sharp provides many other image processing capabilities such as rotating, resizing, and more. With sharp, you can efficiently manipulate images within your Node.js script.
