Astro
Astro is a modern web framework for building fast, content-focused websites with minimal client-side JavaScript. It uses a component-based architecture that allows developers to write UI components using popular frameworks like React, Vue, or Svelte, but ships zero JavaScript by default, rendering components to static HTML at build time. This approach results in highly performant sites with excellent SEO and user experience, particularly suited for blogs, documentation, marketing pages, and e-commerce sites.
Developers should learn Astro when building static or server-rendered websites where performance and SEO are critical, as it eliminates unnecessary JavaScript and delivers content quickly. It's ideal for content-heavy projects like blogs, portfolios, and documentation sites, where you can leverage familiar component frameworks without the overhead of client-side hydration. Use Astro to combine multiple UI frameworks in a single project or when you need partial hydration for interactive components, making it a versatile choice for modern web development.
