Overview

This library introduces an innovative solution for handling middleware in Next.js API routes, which traditionally lacked a straightforward implementation approach. While Next.js has made integrating backend functionality into React applications a breeze, it falls short in easing the integration of middleware. This library aims to create a cleaner, more modular way to implement middleware, making the development experience smoother and more enjoyable.

By adopting a “winding and unwinding stack” model, this library allows developers to add multiple middleware functions to API routes seamlessly. Each middleware function can interact with the request in three distinct phases—setup, waiting, and teardown—providing flexibility without overwhelming complexity.

Features

Winding and Unwinding Stack: Middleware functions operate within a defined sequence, allowing requests to flow through them before reaching the handler and unwinding back, ensuring structured handling of requests.
Flexible Middleware Phases: Each middleware has three phases—setup, waiting, and teardown—enabling developers to manage processes before and after awaiting the next function effectively.
Reusable Middleware Collections: The label utility enables the creation of reusable middleware collections, allowing developers to easily apply common middleware across different API routes.
Simple API Integration: Using withMiddleware, developers can quickly integrate middleware into Next.js API routes, streamlining the development process.
Error Handling Simplicity: The library simplifies error catching in middleware with its structured phases, aiding in creating robust backend services.
Basic and Advanced Use Cases: It supports both straightforward use cases and more specialized configurations, making it adaptable to various project requirements.
Compatibility with Next.js: Specifically designed for Next.js pages router, ensuring seamless integration with existing Next.js structures without the need for complex setups.
