If necessary, you will need to return it as an image by itself. For that, we can use the sharp to handle it for yourself. See the example below:

When sharing content on social media platforms, it's essential to have visually appealing images that are properly sized. Let’s explore how we could automatically resize images for Open Graph and Twitter card previews. We’ll be using sharp - a powerful and fast tool that powers the Image component from Next.js.

Last thing left is to use our new upload function in our server action. Since I like to upload images in single format and have some more control over them, I will additionally use sharp library. For file name, I'll generate some random string using nanoid:

blur is a technique to blur images while reducing the file size surprisingly. blur works by enlarging the pixels of the image, which reduces the details of the image, and the number of colors also decreases, thus saving storage space. Sharp is a popular image processing library in Node.js, and it supports the blur function. After going through the blur function, the image size at this point is only a few KB, which is reasonable for an image placeholder in the article.

For simplicity, I will be generating PNGs with JavaScript/Node and the Sharp image library. Any library that can convert between pixel arrays and image files will make the process quite straightforward.

There is also a library that Next.js itself uses: sharp. It can be setup as Node.js service. I even played around a little: image-proxy-service
