Context

I have made a few iterations on my website, not so much for the safe of the content itself but rather to keep on learning.

At first, I was using a Jekyll blog deployed on Github Pages, then I decided to purchase my own domain and used Netlify to deploy.

Then, at the time I was learning to do a bit of React, I decided to do a complete rewrite with React and Tailwind.

Time passed, and when I was on the verge of migrating to NextJS to get better SEO (for the fans), I came across the recent v1.0 release of Astro

About Astro

Astro 1.0 Astro defines itself as a web framework for building fast, content-focused websites. It is designed for speed thanks to what they call Astro islands: unused JavaScript is replaced with lightweight HTML, guaranteeing faster loads and time-to-interactive (TTI).

Astro also supports both static output (SSG) and live server output (SSR) that can render your content on-demand.

However, the real killing features are:

  • first class citizen support for Markdown and MDX
  • compatibility with common tools like React, Vue, Tailwind …

The rewrite

As all my React components were static, the rewrite was mainly a copy paste of tailwind components to .astro files.

The real benefit it a way cleaner approch on my Markdown blog posts:

const posts = (await Astro.glob('../../blog-posts/*.md')).sort(
  (a, b) => new Date(b.frontmatter.date).valueOf() - new Date(a.frontmatter.date).valueOf()
);

and also a more optimized handling of images by using the Astro native <Image> component

<Image
    src={socialImage}
    format="webp"
    height={96}
    aspectRatio="1:1"
    alt="my picture"
/>

In the end, I managed to reach a 100 Performance score on Lighthouse, more than enough I guess. Lighthouse score

Final notes

Credits to Leosvel for his amazing tutorial that helped me a lot for the rewrite.
