Koa HTTP Proxy Middleware

`koa-proxies` is an HTTP proxy middleware specifically designed for Koa@2.x applications, providing robust proxying capabilities powered by the underlying `http-proxy` library. It enables developers to easily route incoming requests to different target servers, a common pattern for API forwarding, bypassing CORS restrictions during development, or orchestrating microservices. The library currently stands at version 0.12.4. While its latest release dates indicate a more maintenance-focused cadence rather than active feature development (last significant features around 2020), it remains a functional and widely used choice for Koa projects. Key differentiators include its flexible option handling, allowing both static configurations and dynamic determination of proxy settings via a function, and integrated support for `path-match` for advanced routing logic. It also provides built-in TypeScript type definitions since version 0.11.0, enhancing developer experience in TypeScript-based Koa applications.
