Nexpresst 🚀

Nexpresst is a lightweight TypeScript utility designed to build Express-like API routes in Next.js applications. It leverages the Next.js App Router's file-based routing system, providing a structured way to handle HTTP methods, middleware, and response processing—all with strong TypeScript support.

⚠️ Note: This version requires Next.js >= 15.0.0. For Next.js < 15.0.0, please use Nexpresst version 1.X.X.

Features

• Express-like Routing: Use familiar patterns from Express to create API routes in Next.js.
• Express Middleware Adapter: You can leverage existing Express-compatible middleware like helmet, compression, csurf and cors in your Next.js API routes with the expressMiddlewareAdapter.
• Custom Middleware Support: Define global and route-specific middleware for fine-grained request handling.
• Strong TypeScript Support: Utilize TypeScript generics for type-safe request handlers and middleware, ensuring robust and predictable API interactions.
• Easy Integration: Seamlessly integrate with Next.js's App Router and next/server module for a smooth development experience.
