Next.js Middleware Examples

This Gist contains a collection of Next.js Middleware examples that demonstrate various use cases and scenarios for enhancing your Next.js applications. Middleware in Next.js allows you to intercept, modify, and control the flow of requests and responses, making it a powerful tool for building robust web applications.
