Enabling Serverless Functions

Enabling serverless functions allows you to create API routes in your Next.js project by creating files in the pages/api directory. These files automatically become serverless functions that can be deployed to serverless platforms like Vercel or AWS Lambda.

For example, you can create an API route in pages/api/hello.js:

// pages/api/hello.js
export default function handler(req, res) {
  res.status(200).json({ message: "Hello from the serverless function!" });
}

With this setup, you can make requests to /api/hello on your website, and it will execute the serverless function and return the JSON response. Serverless functions are auto-deployed and can scale automatically, making them a great choice for building APIs and dynamic features.
