• #16335 9a53f77 Thanks @ascorbic! - Adds a CDN cache provider for Astro route caching on Vercel

  Setup

  Import cacheVercel() from @astrojs/vercel/cache and set it as your cache provider:

  import { defineConfig } from 'astro/config';
  import vercel from '@astrojs/vercel';
  import { cacheVercel } from '@astrojs/vercel/cache';
  
  export default defineConfig({
    adapter: vercel(),
    cache: {
      provider: cacheVercel(),
    },
  });

  Caching responses

  Use Astro.cache.set() in your pages and API routes to cache responses on Vercel’s edge network. The provider sets Vercel-CDN-Cache-Control and Vercel-Cache-Tag headers on responses.

  ---
  Astro.cache.set({ maxAge: 300, tags: ['products'] });
  const data = await fetchProducts();
  ---
  
  <ProductList items={data} />

  You can also set cache rules for groups of routes in your config:

  cache: { provider: cacheVercel() },
  routeRules: {
    '/products/[...slug]': { maxAge: 3600, tags: ['products'] },
    '/api/[...path]': { maxAge: 60, swr: 600 },
  },

  Invalidation

  Purge cached responses by tag or path from any API route or server endpoint:

  export async function POST({ request, cache }) {
    await cache.invalidate({ tags: ['products'] });
    return new Response('Purged');
  }
  
  // Path-based invalidation
  await cache.invalidate({ path: '/products/123' });

  Both tag-based and path-based invalidation are supported. Tag invalidation is a soft invalidation, marking cached responses as stale so they can be revalidated in the background via stale-while-revalidate.
