Actions

Astro Actions allow you to define and call backend functions with type-safety. Actions perform data fetching, JSON parsing, and input validation for you. This can greatly reduce the amount of boilerplate needed compared to using an API endpoint.

Use actions instead of API endpoints for seamless communication between your client and server code and to:

• Automatically validate JSON and form data inputs using Zod validation.
• Generate type-safe functions to call your backend from the client and even from HTML form actions. No need for manual fetch() calls.
• Standardize backend errors with the ActionError object.

We use actions to handle auth, payments and other areas.
