03:08 - What is it, what does it do?

  • Framework for server-first static apps
  • Use any front-end framework
  • Does not ship JS unless you explicitly define a component to ship JS

05:20 - The syntax

  • .astro files is a mash-up of Svelte and React
  • Frontmatter for server-side JS
  • Template syntax is basically JSX
  • TS baked in
<!-- Hydrates on load -->
<!-- <Test client:load  /> -->

<!-- Hydrates after main thread is free -->
<!-- <Test client:idle  /> -->

<!-- Hydrates as it's in viewport aka LazyLoading-->
<!-- <Test client:visible  /> -->

<!-- Hydrate when matching media query -->
<!-- <Test client:media={'(max-width: 600px)'}  /> -->

<!-- Only renders on the client -->
<!-- <Test client:only  /> -->

07:48 - State management

  • In client-side JS only, no state in .astro files

10:50 - CSS

  • Svelte style
  • Local, scoped
  • SCSS baked in

11:16 - Data fetching

  • Fetch in frontmatter via fetch()

12:06 - Vs React? Vs Next? Vs Gatsby? Vs Svelte?

15:24 - Tooling
