What is Astro? Nedir?
Astro is a modern web framework designed for content-focused websites, shipping zero JavaScript by default.
Astro was developed in 2021 under the leadership of Fred K. Schott as a next-generation web framework optimized for content-focused websites. Astro's core philosophy is the 'Islands Architecture' approach: pages are sent as static HTML by default, and only interactive components are hydrated with JavaScript. Astro's most striking feature is being framework-agnostic. You can use components from different frameworks like React, Vue, Svelte, Solid, and Preact together in the same project. This makes it easy to leverage existing component libraries and balance team preferences. Astro offers structured content management with Content Collections, page transition animations with View Transitions, and server-side rendering support with SSR adapters. Markdown and MDX are natively supported, making it ideal for blogs and documentation sites. With its performance-focused approach, Astro achieves excellent Lighthouse scores. Companies like Google, Microsoft, Porsche, and NordVPN use Astro for documentation and marketing sites.
