astro@5.0.0-beta.8

Minor Changes

• #12373 d10f918 Thanks @​bholmesdev! - Changes the default behavior for Astro Action form requests to a standard POST submission.

  In Astro 4.x, actions called from an HTML form would trigger a redirect with the result forwarded using cookies. This caused issues for large form errors and return values that exceeded the 4 KB limit of cookie-based storage.

  Astro 5.0 now renders the result of an action as a POST result without any forwarding. This will introduce a "confirm form resubmission?" dialog when a user attempts to refresh the page, though it no longer imposes a 4 KB limit on action return value.

  Customize form submission behavior

  If you prefer to address the "confirm form resubmission?" dialog on refresh, or to preserve action results across sessions, you can now customize action result handling from middleware.

  We recommend using a session storage provider as described in our Netlify Blob example. However, if you prefer the cookie forwarding behavior from 4.X and accept the 4 KB size limit, you can implement the pattern as shown in this sample snippet:

  // src/middleware.ts
  import { defineMiddleware } from 'astro:middleware';
  import { getActionContext } from 'astro:actions';
  export const onRequest = defineMiddleware(async (context, next) => {
  // Skip requests for prerendered pages
  if (context.isPrerendered) return next();
  const { action, setActionResult, serializeActionResult } = getActionContext(context);
  // If an action result was forwarded as a cookie, set the result
  // to be accessible from Astro.getActionResult()
  const payload = context.cookies.get('ACTION_PAYLOAD');
  if (payload) {
  const { actionName, actionResult } = payload.json();
  setActionResult(actionName, actionResult);
  context.cookies.delete('ACTION_PAYLOAD');
  return next();
  }
  // If an action was called from an HTML form action,
  // call the action handler and redirect with the result as a cookie.
  if (action?.calledFrom === 'form') {
  const actionResult = await action.handler();
  context.cookies.set('ACTION_PAYLOAD', {
    actionName: action.name,
    actionResult: serializeActionResult(actionResult),
  });
  if (actionResult.error) {
  // Redirect back to the previous page on error
  const referer = context.request.headers.get('Referer');
  if (!referer) {
