Hi @WiFi Plug. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To display the amount of Discord members on your Nuxt 3 website and cache the result for 10 minutes, you have several caching options, especially with the latest Nuxt/Nitro features. 1. Route Rules (Recommended for Simplicity) Nuxt 3 supports hybrid rendering and route-level caching using routeRules in your nuxt.config.ts. This is the simplest and most maintainable way to cache API responses for a specific duration. For your use case (caching a server route for 10 minutes = 600 seconds): 
// nuxt.config.ts
export default defineNuxtConfig({
  routeRules: {
    '/api/discord-members': { swr: 600 } // 600 seconds = 10 minutes
  }
})
// nuxt.config.ts
export default defineNuxtConfig({
  routeRules: {
    '/api/discord-members': { swr: 600 } // 600 seconds = 10 minutes
  }
})
- swr stands for "stale-while-revalidate": the cached response is served instantly, and a background refresh happens after the TTL expires. - This approach is easy to set up and works well for endpoints like your Discord member count. - Nuxt/Nitro will handle the cache automatically for you, and you don't need to write any extra code in your API handler for caching logic. Pro tip: This is the most "pro" and idiomatic way in Nuxt 3 to cache API responses for a set duration, as it leverages Nitro's built-in caching layer and keeps your codebase clean and maintainable. You can read more about this in the Nuxt docs on hybrid rendering and route rules. 2. Manual Caching in API Handlers If you need more control, you can use Nitro's defineCachedEventHandler in your API route: 
// server/api/discord-members.ts
export default defineCachedEventHandler(async (event) => {
  // Fetch Discord member count from your source
  const count = await fetchDiscordMemberCount()
  return { count }
}, {
  maxAge: 600 // 10 minutes in seconds
})
// server/api/discord-members.ts
export default defineCachedEventHandler(async (event) => {
  // Fetch Discord member count from your source
  const count = await fetchDiscordMemberCount()
  return { count }
}, {
  maxAge: 600 // 10 minutes in seconds
})
- This gives you fine-grained control over caching at the handler level. - Useful if you want to cache only part of the logic or have dynamic cache keys. 3. Client-side Caching (for useFetch/useAsyncData) Nuxt 3.8 introduced getCachedData for client-side caching with useFetch and useAsyncData, but for your use case (server API route), server-side caching is more appropriate. Client-side caching is best for avoiding extra requests from the same user during navigation, not for sharing cached data across all users. Summary - Best practice: Use routeRules with swr for your API route to cache the Discord member count for 10 minutes. - Advanced: Use defineCachedEventHandler for more control. - Client-side caching is not suitable for this use case.
