🍿 Minor Changes

• #11071 8ca7c73 Thanks @bholmesdev! - Adds two new functions experimental_getActionState() and experimental_withState() to support the React 19 useActionState() hook when using Astro Actions. This introduces progressive enhancement when calling an Action with the withState() utility.

  This example calls a like action that accepts a postId and returns the number of likes. Pass this action to the experimental_withState() function to apply progressive enhancement info, and apply to useActionState() to track the result:

  import { actions } from 'astro:actions';
  import { experimental_withState } from '@astrojs/react/actions';
  
  export function Like({ postId }: { postId: string }) {
    const [state, action, pending] = useActionState(
      experimental_withState(actions.like),
      0 // initial likes
    );
  
    return (
      <form action={action}>
        <input type="hidden" name="postId" value={postId} />
        <button disabled={pending}>{state} ❤️</button>
      </form>
    );
  }

  You can also access the state stored by useActionState() from your action handler. Call experimental_getActionState() with the API context, and optionally apply a type to the result:

  import { defineAction, z } from 'astro:actions';
  import { experimental_getActionState } from '@astrojs/react/actions';
  
  export const server = {
    like: defineAction({
      input: z.object({
        postId: z.string(),
      }),
      handler: async ({ postId }, ctx) => {
        const currentLikes = experimental_getActionState<number>(ctx);
        // write to database
        return currentLikes + 1;
      },
    }),
  };
