This November, I published an article about Image Optimization On Jamstack Sites in Smashing Magazine. In this recap, I want to tell you what it is about, the sections and concepts covered in it, and show you the demo used to demonstrate the theory explained.
Who is this article intended for?
For developers and designers who want to improve the quality and performance of their projects containing images.
Anyone who wants to learn new image optimization techniques, reaffirm their knowledge on the subject, or catch up on the latest trends.
What sections make up this article?
The article comprises 5 sections covering theory, problems in working with images, and their theoretical and practical solutions, ending with a step-by-step case study.
Introduction
It begins with a brief introduction to the importance of web performance today, its relationship to images, and how images impact the health of Jamstack sites.
Then, we present the most common problems when using images in our projects and what would be the optimization technique or theoretical solution for each one of them.
This section talks about the types of compression, the use of next-generation formats such as WebP and AVIF, the mandatory definition of width and height attributes in img and source tags, the optimization of images by device, resolution, and size, the lazy or eager loading technique, and the use of server and client cache.
The benefits of using an Image Service CDN
Next, we show a solution to each of the problems mentioned in the previous section by simply using an image CDN and discovering its simplicity and the advantages, flexibility, and scalability that it provides to our projects.
Case study: Image component in a Jamstack site
And with all the theories presented, it only remained to show an example project of how all these techniques could be carried out using Storyblok as a Headless CMS and image CDN provider. In this part, we present a static site generated by Nuxt 3, a custom image component created with Vue 3 and script setup, although it could be implemented in any other technology.
