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.
