Astro
Astro is a content-driven web framework designed for building multi-page applications that prioritize performance by shipping minimal JavaScript to the browser. It functions as a static site generator and server-side rendering engine, transforming source files into optimized HTML documents. By utilizing an island architecture, the framework isolates interactive components within static pages, ensuring that only necessary code is hydrated on the client side.
The framework provides a unified build pipeline that supports component-agnostic rendering, allowing developers to integrate components from various UI libraries into a single project. It enforces content-collection type safety through schema-based validation for local data files and generates search-engine-friendly pages to ensure proper indexing.
Beyond its core rendering capabilities, the project includes build-time asset optimization to process and transform images, scripts, and styles for reduced payload sizes. You can initialize a new project by running the create command via your package manager.
