Features

Component caching

Use the <RenderCacheable> wrapper component to cache the markup of the default slot:

<template>
  <div>
    <RenderCacheable cache-key="navbar_de" :max-age="3600">
      <Navbar />
    </RenderCacheable>
  </div>
</template>

The component is only rendered once and its markup cached. Afterwards the markup is directly returned.

Route caching

Cache rendered pages or custom API responses:

<script lang="ts" setup>
useRouteCache((route) => {
  // Mark the page as cacheable for 1 hour and add a cache tag.
  route
    .setCacheable()
    .setMaxAge(3600)
    .addTags(['page:2'])
})
</script>

CDN cache control headers

Manage the cacheability for the current response. This will set the correct cache control and cache tags headers for Cloudflare, Fastly and other cache providers:

<script lang="ts" setup>
useCDNHeaders((helper) => {
  helper
    .public()
    .setNumeric('maxAge', 3600)
    .setNumeric('staleWhileRevalidate', 21600)
    .set('mustRevalidate', true)
    .addTags(['page:2', 'image:342'])
})
</script>

The state is managed inside the current request and can be changed for the entire duration of the request. The headers are generated right before the response is sent.

API

The optional API provides endpoints to manage the caches.
