valibot VS sharp

What if you use a schema library, like Zod or Valibot? The schema has been built on value-level, and you cannot assign the variant to its property inside the declaration.

I'll use Valibot library, which is a pretty new and cool library for schema validation, similar to Zod.

The ModelFusion zodSchema function wraps the Zod object definition. This is necessary because ModelFusion supports Zod and unchecked JSON schemas and is adaptable to other schema validation libraries such as Valibot.

There was already existing validation in place for the question form page using Valibot, so I only needed to change two lines of code. I imported includes in addition to the other Valibot functions, and I also added an a new line of validation using the includes function to ensure the string has at least one space (If it does not the corresponding error message will be displayed). I had never used Valibot before, but it was easy to learn by looking at the web documentation as well as the existing code. See screenshots of my fix in my PR.

Valibot (good for types and constraints)

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
