The Astro 4.8 release ships with another powerful and long-awaited feature: Astro server actions. Server actions in Astro enable you to define and call backend functions with TypeScript's safety features.
A second great feature in the 4.8 release is the ability to rewrite URL requests, also known as rerouting in other frameworks.
Astro actions are backend type-safety functions that can be called from the frontend. They contain features like RPC actions, built-in formData validator, and support for React 19 actions.
Actions in Astro empower developers by accepting JSON and formData payloads, triggering through HTML forms, providing progressive enhancement for non-JavaScript scenarios, and enabling safe request body parsing with reduced boilerplate code.
