Minor Changes

• #13527 2fd6a6b Thanks @ascorbic! - The experimental session API introduced in Astro 5.1 is now stable and ready for production use.

  Sessions are used to store user state between requests for on-demand rendered pages. You can use them to store user data, such as authentication tokens, shopping cart contents, or any other data that needs to persist across requests:

  ---
  export const prerender = false; // Not needed with 'server' output
  const cart = await Astro.session.get('cart');
  ---
  
  <a href="/checkout">🛒 {cart?.length ?? 0} items</a>

  Configuring session storage

  Sessions require a storage driver to store the data. The Node, Cloudflare and Netlify adapters automatically configure a default driver for you, but other adapters currently require you to specify a custom storage driver in your configuration.

  If you are using an adapter that doesn't have a default driver, or if you want to choose a different driver, you can configure it using the session configuration option:

  import { defineConfig } from 'astro/config';
  import vercel from '@astrojs/vercel';
  
  export default defineConfig({
    adapter: vercel(),
    session: {
      driver: 'upstash',
    },
  });

  Using sessions

  Sessions are available in on-demand rendered pages, API endpoints, actions and middleware.

  In pages and components, you can access the session using Astro.session:

  ---
  const cart = await Astro.session.get('cart');
  ---
  
  <a href="/checkout">🛒 {cart?.length ?? 0} items</a>

  In endpoints, actions, and middleware, you can access the session using context.session:

  export async function GET(context) {
    const cart = await context.session.get('cart');
    return Response.json({ cart });
  }

  If you attempt to access the session when there is no storage driver configured, or in a prerendered page, the session object will be undefined and an error will be logged in the console:

  ---
  export const prerender = true;
  const cart = await Astro.session?.get('cart'); // Logs an error. Astro.session is undefined
  ---

  Upgrading from Experimental to Stable

  If you were previously using the experimental API, please remove the experimental.session flag from your configuration:

  import { defineConfig } from 'astro/config';
  import node from '@astrojs/node';
  
  export default defineConfig({
     adapter: node({
       mode: "standalone",
     }),
  -  experimental: {
  -    session: true,
  -  },
  });

  See the sessions guide for more information.
