️Build backend features in Nuxt - without a backend.⚡

With Nitro + H3, every file in `/server/api` becomes a serverless function ready to deploy to Vercel, Netlify, or Cloudflare.

Read how it works 👇
https://certificates.dev/blog/serverless-functions-in-nuxt-backend-power-without-a-backend
Serverless functions in Nuxt: backend power without a backend
Serverless functions are tiny pieces of code that run on demand in the cloud. You don’t provision servers or infrastructure, or write scaling rules. Cloud providers handle the underlying infrastructure, automatically scaling resources based on demand. They’re perfect for lightweight APIs, form handlers, webhooks, simple auth endpoints, and glue code.

Advanced data fetching in Nuxt just got smarter. 🤓

In his latest article, Reza Baar dives into powerful features in `useFetch` and `useAsyncData`, like:
📛 `dedupe: 'defer'`
🔁 `retry`, `retryDelay`
⏳ `delay`

Find out more 👇
https://certificates.dev/blog/data-fetching-game-in-nuxt-advanced-level
Data Fetching Game in Nuxt: Advanced Level
This article shows how Nuxt uses enhanced control in useFetch / useAsyncData: with dedupe: 'defer' to skip duplicate fetches, retry & retryDelay to handle flaky endpoints, and delay to smooth UI transitions. These options yield cleaner, faster, and more resilient data flows—especially helpful for reactive interfaces and unstable networks.
