Astro, a framework focused on content sites, is evolving with the introduction of server-side rendering (SSR) support, expanding its application to larger CMS-backed sites and e-commerce platforms. This new feature simplifies template syntax, allowing for mostly HTML-based templates with sprinkles of JavaScript where needed. API routes are also introduced, enabling non-HTML requests such as POST requests for user profile updates or GET requests for dynamically retrieving JSON data. Astro's SSR support is being deployed to Netlify, a popular platform for deploying static sites, and can be used in conjunction with Netlify Functions, which enable building dynamic applications quickly. With this feature, developers can handle redirects, 404s, and other dynamic response codes directly in their templates, as well as handle non-GET HTTP methods and API calls from the client.
