This is achieved by placing files inside the pages/api directory. Each file within this directory is treated as an API route and becomes an endpoint that can be accessed by making HTTP requests. This approach eliminates the need for a separate server for your API, streamlining development and deployment processes.

For instance, creating a file named user.js inside the pages/api directory automatically generates an API route /api/user. Within this file, you can export a default function that handles incoming requests. This function receives two arguments: req (the request object) and res (the response object).
